Hydatid cyst of spleen: a diagnostic challenge

Ruptured splenic hydatid cyst

Hydatid cysts of the spleen are rare. Our report details a case wherein an 8-year-old boy with a ruptured splenic hydatid cyst suffered ongoing abdominal pain and shock. Computed Tomography (CT) imaging showed an irregular cyst at the spleen's lower edge with a "floating membranes" sign. Emergency surgery was performed to remove the hydatid cyst and repair the ruptured spleen. During follow-up, the patient was treated with Albendazole orally for 12 months.

Giant isolated splenic hydatid cyst in a pediatric patient: A rare case report

INTRODUCTION

Hydatidosis, caused by Echinococcus granulosus, is endemic in regions where cattle rearing is prevalent. While liver and lung involvement are common, isolated splenic hydatid cysts are rare, particularly among adolescents. We present a rare case of a 14-year-old female with an isolated giant splenic hydatid cyst.

CASE PRESENTATION

A 14-year-old female presented with left upper quadrant pain. Imaging revealed a large splenic cyst without evidence of liver or lung involvement. A total splenectomy was performed, and a histological examination confirmed the diagnosis of a hydatid cyst. The patient underwent postoperative albendazole therapy and remained asymptomatic during follow-up.

CLINICAL DISCUSSION

Isolated splenic hydatid cysts are rare in the pediatric population. Imaging techniques such as ultrasound and CT play a crucial role in diagnosis. Surgical resection and Puncture-aspiration-injection-reaspiration remain the choice of treatment, supplemented by anti-parasitic therapy. Postoperative follow-up is essential to monitor for recurrence.

CONCLUSION

Isolated splenic hydatid cysts are exceptionally rare in pediatric patients. Prompt diagnosis, surgical intervention, and postoperative surveillance are crucial for successful management and prevention of recurrence.

A Case Series of Isolated Primary Hydatid Cyst of the Spleen

Hydatid disease is endemic mainly in Asia and other sheep-raising areas. In India, hydatid disease has been a very common disease because of its close association with livestock rearing. Hydatid disease is a parasitic infestation caused by Echinococcus granulosus. The usual location of infestation is in the liver sinusoids, lungs, and spleen. Hydatid disease in humans is rare, and a hydatid cyst of the spleen without involving the liver is very rare. The rarity of splenic hydatid disease may pose a diagnostic challenge for clinicians, especially in non-endemic areas. The diagnosis of hydatid disease is based on the epidemiological background of patients, clinical grounds, or noninvasive screening procedures. With this background, we aimed to study the presenting symptomatology and various clinical manifestations of isolated spleen hydatid disease and analyze the morbidity and mortality of hydatid disease. Different surgical modalities and their complications were studied. Three patients operated on for splenic hydatid at our institute were studied retrospectively.

A Stellar Case of Splenic Hydatid Cyst

Hydatid disease, also known as hydatidosis or echinococcosis, is a zoonotic infection caused by cestode, namely Echinococcus granulosus (tapeworm). Humans are the incidental hosts that acquire the infection by being in contact with infected animals or through the fecal-oral route via contaminated feces. Hydatid disease of the spleen is a zoonotic disease of rare occurrence. Most often, the patients do not have any specific symptoms except dull dragging pain in the abdomen. In some unfortunate cases, the patient may present with an acute abdomen or anaphylactic shock state due to rupture of the cyst, which is a medical and surgical emergency. The mainstay of treatment remains albendazole and praziquantel medically, along with surgery, i.e., splenectomy. A 30-year-old female presented in the OPD with complaints of pain in the abdomen for the last two years with no other complaints. The pain did not respond to regular analgesics and antacids. The patient was admitted for further evaluation. A contrast-enhanced computed tomography (CECT) abdomen was done for the patient, which showed splenomegaly along with features suggestive of a splenic hydatid cyst. The lady was taken for a planned splenectomy. The histopathological features were suggestive of a hydatid cyst of the spleen. The mainstay of treatment is medically anthelmintic medications and surgical splenectomy along with the puncture aspiration injection re-aspiration (PAIR) technique.

Splenic Hydatid Cyst Presenting As Non-cirrhotic Portal Hypertension: A Rare Case Report

Hydatid cystic disease, also called cystic echinococcosis, arises from Echinococcus, a tapeworm infestation. It results in developing cysts primarily in the liver, although they can also occur in other organs. While the spleen is an uncommon site for cyst formation, it can still be affected. These infections are more prevalent in rural and underdeveloped regions, particularly among individuals involved in livestock rearing and animal care. The case we came across was of a 32-year-old female from a rural background engaged in animal handling and farming. She presented to our hospital with left hypochondriac pain, decreased appetite, and generalized weakness, but the patient had a history of two episodes of melena, which was self-limiting. Subsequent investigations revealed a diagnosis of splenic hydatid cyst with perisplenic collaterals and cystic compression of the splenic vein, causing symptoms of non-cirrhotic portal hypertension. Here, we present a unique case of splenic hydatid cyst leading to non-cirrhotic portal hypertension. This rare presentation poses diagnostic challenges and emphasizes the importance of considering parasitic infections in differential diagnoses.

Primary hydatid cyst of the spleen: A rare case report and literature review

Hydatidosis is an endemic disease in certain areas in the world particularly in the Mediterranean, the Middle East, and South America, caused by a cestode known as Echinococcus granulosus. Humans are the accidental intermediate hosts. The liver and the lungs are the most commonly involved organ. If the parasite passes through the pulmonary capillary bed, the hydatid cyst may develop at any site in the body like bone, pancreas, brain, kidney, and orbit. Isolated spleen hydatid cyst is very rare. We hereby report one observation of isolated hydatid cyst of the spleen in a patient living in non-endemic area and without any potential risk.

Postpartum Spontaneous Rupture of a Primary Splenic Hydatid Cyst: A Case Report

Hydatid disease is endemic in some regions of the world. Even in endemic regions, splenic hydatid cysts are rare, especially in pregnancy. The most serious presentation is intra peritoneal rupture, which is a surgical emergency. Exploration with splenectomy is the favoured management. We present a case of splenic hydatid cyst, detected late in pregnancy, with intraperitoneal rupture in the postpartum period. Cystic lesions located anywhere in the body in endemic regions could be hydatid cysts. Prompt treatment should be planned immediately on detection in order to prevent potentially serious complications like rupture.

A 16-year-old adolescent with a history of minor abdominal trauma diagnosed with a giant isolated primary splenic hydatid cyst: a case report

Introduction

Hydatosis is a zoonotic parasitic disease caused by echinococcosis larval infection. South America, Africa, the Middle East, South Europe, India, and Australia are endemic to this disease. Splenic involvement is a rare and complicated hydatid disease presentation. A splenic hydatid cyst is an infrequent clinical occurrence, even in regions where the disease is endemic.

Case presentation

A 16-year-old male, having a background of mild abdominal trauma and non-resolving dull abdominal pain attended a paediatric surgical outpatient office and following a thorough examination, was diagnosed with a giant solitary isolated splenic hydatid cyst. Subsequently, the patient received albendazole and underwent total splenectomy, necessitated by the considerable size of the cyst, classified as a giant.

Clinical discussion

Splenic involvement of hydatid disease is a rare presentation (0.5-8%.). With the initial clinical finding often involving the accidental discovery of a palpable mass, the most frequently reported symptoms and signs include the presence of a palpable mass, fever, dull pain, or splenomegaly. Ultrasound and computed tomography are the most helpful tools for evaluating focal splenic diseases. The preferred treatment involves the use of antihelminthic drugs such as albendazole or mebendazole in conjunction with splenectomy. Total splenectomy is the preferred approach and is associated with decreased hospital stay, reduced healthcare costs, and a lower likelihood of recurrence.

Conclusion

in endemic areas, in patients with splenic cysts, hydatidosis should be contemplated.

Spleen-preserving surgery for splenic hydatid cyst: a case report

Hydatidosis is a zoonosis due to the development of the larval form of Echinococcus granulosus in humans. This disease is very frequent in many countries of North Africa such as Morocco. The most frequent locations of hydatid cysts are the liver (75%) and the lungs (15.4%). Splenic hydatid cyst occurs in only 5.1% of cases. The diagnosis remains challenging and is made upon a hundle of clinical, radiological, biological, and histological arguments. In this paper, we report a case of spleen-preserving surgery for a splenic hydatid cyst to suggest the best management of these hydatid cysts and avoid recurrences.

Pre-extensively Drug-Resistant Pulmonary Tuberculosis With a Giant Primary Splenic Hydatid Cyst With Multiple Adverse Drug Reactions

Drug-resistant tuberculosis is a noteworthy threat to public health, especially in high-burden countries. Management of these types of tuberculosis is lengthy and associated with a number of adverse drug reactions. Pre-extensively drug-resistant tuberculosis is a serious type of disease that is caused by the strains of Mycobacterium tuberculosis that are resistant to either rifampicin or both, i.e., rifampicin and isoniazid, and resistant to any fluoroquinolones. A splenic hydatid cyst is relatively rare and has never been reported in a case of pre-extensively drug-resistant pulmonary tuberculosis. The present case is a rare case of a young Indian male who was diagnosed with pre-extensively drug-resistant pulmonary tuberculosis through a cartridge-based nucleic acid amplification test and second-line drug susceptibility testing. Further, a diagnostic radiometric investigation showed a giant hydatid cyst in the spleen. He was started on an all-oral longer treatment regimen per the existing protocols. However, his treatment was associated with multiple adverse drug reactions.

Laparoscopic Management of Multiple Liver, Omental, Mesenteric, Peritoneal, and Round Ligament Hydatid Cysts-A Rare Report of a Case and a Systematic Literature Review

Hydatid cyst disease is a parasitic ailment with an endemic nature, predominantly affecting geographical areas with a tradition in animal husbandry. The most common localization of hydatid disease is in the liver (60%), followed by the lungs, with other organ localizations comprising less than 10%. The surgical approach to this condition can be carried out through open surgery or laparoscopy. The coexistence of hepatic and intraperitoneal hydatidosis often leads to the preference for open surgery. We performed a literature review aiming to retrieve data regarding demographic characteristics, clinical features, preoperative management, and surgical approach concerning these unusual localizations of hydatid disease. It was observed that the mesenteric localization frequently presented with acute abdominal pain (p = 0.038) and that the open approach was preferred in 85.71% of cases. Furthermore, an interdependence was identified between the localization of the cysts and the type of surgical approach (p = 0.001), with mesenteric localizations being approached through laparotomy and excision (p = 0.037), while omental localizations, due to the easier approach, benefited from laparoscopy with excision in 14.29% of cases. Overall, the laparoscopic approach was less frequently used, but its utilization resulted in a lower number of complications and faster recovery. Additionally, we present a rare case of hepatic and intra-abdominal hydatidosis, resolved exclusively through a laparoscopic approach, including a review of the literature for these uncommon localizations of hydatid disease. A 45-year-old patient diagnosed with multiple hydatid cysts, both hepatic and intraperitoneal, underwent surgical intervention with exploratory laparoscopy. Laparoscopic excision of peritoneal, epiploic, mesenteric cysts, and round ligament, along with laparoscopic inactivation, evacuation, and pericystectomy of hepatic hydatid cysts, was performed. The patient's recovery was uneventful, and she was reevaluated at 3 and 9 months without signs of recurrence. The association of hepatic hydatid cysts with multiple intra-abdominal localizations is not commonly encountered. The treatment of choice is surgical and is predominantly conducted through open surgery. The presented case is unique due to the exclusive laparoscopic approach in the management of mixed hepatic and intra-abdominal hydatidosis.

A rare simultaneous occurrence of splenic and ovarian hydatid cyst: A case report

INTRODUCTION AND IMPORTANCE

Hydatid disease is an infectious illness caused by a parasite called Echinococcus. It can affect any organ, primarily the liver and lungs. The occurrence of splenic or ovarian hydatid cyst is rare; simultaneous involvement of both is extremely uncommon. This case report provides valuable insights to clinicians, guiding them to consider a hydatid cyst as a potential differential diagnosis in the presence of a cystic mass lesion.

CASE PRESENTATION

A 33-year-old female presented with abdominal pain of 10 years duration. The past medical and surgical history was negative. Ultrasound and CT scans of the abdomen showed double-layered splenic (15.3 cm × 12.8 cm × 15 cm) and pelvic (8.4 cm × 10.3 cm × 9 cm) cysts. Laparotomy revealed splenic and ovarian hydatid cysts with adhesions to surrounding structures. We performed total splenectomy and left salphingo-opherectomy, yielding excellent outcome.

DISCUSSION

Hydatid cysts of the spleen and ovary are rare, with few case reports. It is usually secondary to systemic dissemination or intra-peritoneal spread from a ruptured hepatic cyst. Imaging modalities such as ultrasound and CT scans can aid in reaching a diagnosis. The standard treatment for a hydatid cyst is surgery.

CONCLUSION

The simultaneous occurrence of hydatid cysts in the spleen and ovary is rare. The diagnosis is challenging due to nonspecific clinical presentations, necessitating a high level of suspicion. Surgery is the primary treatment for hydatid cysts.

Lung Hydatidosis Unveiled: A Multisystem Mirage of Pathological Rarity

Lung hydatidosis is a zoonotic infection, primarily caused by Echinococcus sp., and has a significant role in the economy and public health. Canines are the predominant hosts of these parasitic tapeworms. Lungs are the most commonly infected organ after the liver. Hepatic pulmonary blood circulation is mainly reported to transport infection to the lungs. The prevalence of hydatid disease has increased over the past decade. In addition, patients with multi-organ involvement of hydatid cysts have been reported in different parts of the world. Hydatidosis can remain asymptomatic for years after infection in some conditions, especially in cases of splenic hydatidosis. Chest radiography and computed tomography findings can be used to confirm the diagnosis of hydatid disease. Hydatid disease is, in general, managed by pharmacological therapy, but if multi-organ involvement is observed, surgery along with medical management is required. Long-term follow-up is recommended in such cases to check the recurrence of the disease.

Challenges and Prospective of Enhancing Hydatid Cyst Chemotherapy by Nanotechnology and the Future of Nanobiosensors for Diagnosis

Hydatid cysts have been widely recognized for decades as a common medical problem that affects millions of people. A revolution in medical treatment may be on the prospect of nanotechnology enhancing chemotherapy against hydatid cysts. An overview of nanotechnology's impact on chemotherapeutics is presented in the current review. It discusses some of the challenges as well as some of the opportunities. The application of nanotechnology to enhance chemotherapy against hydatid cysts is what this review will explore. Nanotechnology is a critical component of delivering therapeutic agents with greater precision and efficiency and targeting hydatid cysts with better efficacy, and minimizing interference with surrounding tissue. However, there are biodistribution challenges, toxicity, and resistance problems associated with nanotherapeutics. Additionally, nanobiosensors are being investigated to enable the early diagnosis of hydatid cysts. A nanobiosensor can detect hydatid cysts by catching them early, non-invasively, rapidly, and accurately. The sensitivity and specificity of diagnostic tests can be enhanced with nanobiosensors because they take advantage of the unique properties of nanomaterials. By providing more precise and customized treatment options for hydatid cysts, nanotechnology may improve therapeutic options and strategies for diagnosing the disease. In conclusion, treatment with nanotechnology to treat hydatid cysts is potentially effective but presents many obstacles. Furthermore, nanobiosensors are being integrated into diagnostic techniques, as well as helping to diagnose patients earlier and more accurately.

A massive primary hydatid splenic cyst was successfully managed through open total splenectomy: a case report and review article

Background

Cystic echinococcosis (CE) is a parasitic infection that is caused by the tapeworm Echinococcus granulosus. CE is very common, especially in the rural areas of developing countries. The most commonly affected organs by hydatid cysts are the liver and the lungs. However, the primary splenic hydatid cyst (PSHC) is a very rare manifestation of CE with an incidence of 0.5-8%.

Case presentation

A 17-year-old female patient presented with abdominal pain which gradually increased over months, along with anorexia and vomiting. Computerized tomography showed a massive splenic cystic mass. An open total splenectomy was performed. By follow-up, the platelet count and a postoperative chest X-ray were normal. The patient was prescribed Albendazole and analgesics. The pathological study confirmed the diagnosis of PSHC.

Conclusion

Despite the occurrence of PSHC being very rare, it is very important to take it into consideration, especially in endemic areas.

A rare case of recurrent hydatid cyst of the spleen: A case report

Cystic echinococcosis (CE), or hydatid disease, is a parasitic infection caused by Echinococcus granulosus endemic to areas with considerable pastoral farming and animal husbandry. Typical presentations include hydatid cyst formation in the liver, lungs, brain, kidneys, or bones. An isolated splenic hydatid cyst is an extremely rare occurrence, accounting for only 0.5%-4% worldwide incidence rates, and recurrent cases are even more infrequent. Globalization, cross-border travel, and altered immigration patterns over time have shifted some of the burden of CE from the developing to the developed world, making the diagnosis challenging for these nonendemic areas. Judicious use of imaging modalities for prompt diagnosis and effective intervention is necessary to treat the initial disease and prevent a recurrence. Herein, we present the case of a 13-year-old male with recurrent isolated splenic hydatid cyst. The patient presented with chronic and nonradiating pain in his left hypochondrium. Physical examination revealed splenomegaly. Ultrasonography showed multiple cysts. Computerized tomography (CT) scan showed cystic lesions in splenic parenchyma with numerous internal enhancing septae. Surgical evacuation was performed for the management of disease.

An Unexpected Finding of Isolated Hydatidosis of the Spleen With Concomitant Visceromegaly in an Elderly Female

Hydatidosis of the spleen is a rare zoonotic clinical entity. The occurrence of isolated splenic hydatid cysts in the absence of these cysts in any other portion of the body is referred to as primary splenic hydatidosis. It is a rare disorder that accounts for only 2% of the burden of hydatid disease worldwide. After the liver and the lungs, the spleen is the organ that is most frequently affected by this condition.

Echinococcal Disease of the Fallopian Tube as a Rare Cause of Primary Subfertility

Echinococcosis is a significant zoonotic infection caused by Echinococcus granulosus, which has a worldwide distribution. In India, the annual incidence varies from one to 200 in 100,000 people. The liver and lungs are often affected, making diagnosis difficult when infections occur in uncommon areas. We report a case of a hydatid cyst in the fallopian tube, which presented as subfertility and was confirmed by radiological imaging.

Giant splenic cyst: A case series of rare and challenging cases from the last 22 years

INTRODUCTION AND IMPORTANCE

Splenic cyst is a rare disease, with reported incidences ranging from 0.07 to 0.3 %. A splenic cyst is typically discovered inadvertently and may not cause any symptoms until it grows to a significant size. In some cases, complications such as acute abdomen may be brought on by an intracystic hemorrhage, rupture, or infection. As a rare disease, diagnosing a splenic cyst is still precarious because only a few cases have been reported.

CASE PRESENTATION

The first case is a 23-year-old Asian man without a significant history of illness who complains of a left upper quadrant mass that he discovered 10 years prior. Since then, the mass had been gradually growing and had been accompanied by severe pain. Walking made the pain worse; lying down made it lessen. A computed tomography (CT) scan of the abdomen showed a 20.05 × 15.95 × 26.71 cm splenic cyst. Surgery for a peri-cystic splenectomy was done. A primary splenic cyst was identified in the specimen after microscopic and macroscopic examination. After 10 days, the patient was released from the hospital without complications. The second case is that of a 28-year-old Asian man who complained of a mass in their abdomen that was getting bigger in size. Four years prior to the complaint, the patient had fallen while driving a motorcycle, and the left side of his abdomen collided with the sidewalk. In this patient, a splenectomy-the complete removal of all spleen parts-was done. The specimen's macroscopic and microscopic examination revealed a splenic pseudocyst. The patient was discharged after three days without complications.

CLINICAL DISCUSSION

Splenic cysts are considered rare and challenging to diagnose, as there have been only a limited number of reports. Nevertheless, proper management is still needed, as it carries the risk of rupturing and causing complications such as peritonitis and anaphylactic reactions. Considering the risk of overwhelming post-splenectomy infection (OPSI), conservative treatment can be the gold standard for splenic cysts. However, considering the risk from the size of the cyst, splenectomy or peri-cystic splenectomy is an appropriate surgery option for a splenic cyst.

CONCLUSION

Splenectomy, or peri-cystic splenectomy, is a surgery option for a splenic cyst with significant size and rupture risk.

The Neoplasms Mimicker: A Pictorial Review of Hydatid Disease

Hydatid cyst is a common name for the larval stage of a tapeworm species of the genus Echinococcus granulosus, which is transmitted from animals to humans via the fecal–oral route. Hydatid cysts predominantly affect the liver (75%), followed by the lung (15%), and they can affect many organs in the human body. Medical imaging modalities are the keystone for the diagnosis of hydatid cysts with high sensitivity and specificity. Ultrasound imaging with high resolution is the first choice for diagnosis, differential diagnosis, staging, establishing a role in interventional management, and follow-up, and it can differentiate Type I hydatid cysts from simple liver cysts. Unenhanced computed tomography (CT) is indicated where or when an ultrasound is unsatisfactory, such as with chest or brain hydatid cysts, when detecting calcification, and in obese patients. Magnetic resonance imaging (MRI) is superior for demonstrating cyst wall defects, biliary communication, neural involvement, and differentiating hydatid cysts from simple cysts using diffusion-weighted imaging (DWI) sequences. According to the phase of growth, hydatid cysts occur in different sizes and shapes, which may mimic benign or malignant neoplasms and may create diagnostic challenges in some cases. Hydatid cysts can mimic simple cysts, choledochal cysts, Caroli’s disease, or mesenchymal hamartomas of the liver. They can mimic lung cystic lesions, mycetoma, blood clots, Rasmussen aneurysms, and even lung carcinomas. Differential diagnosis can be difficult for arachnoid cysts, porencephalic cysts, pyogenic abscesses, and even cystic tumors of the brain, and can create diagnostic dilemmas in the musculoskeletal system.

An Isolated Splenic Hydatid Cyst

An isolated hydatid cyst of the spleen is a rare presentation of echinococcal diseases, especially in non-endemic areas where it may end up with unnecessary work-up and misdiagnosis. Here, we present the case of a 28-year-old female presenting with generalized abdominal pain, constipation, and early satiety who had a delayed diagnosis of isolated splenic hydatid cyst which was partially treated with albendazole, eventually requiring splenectomy.

Hydatid Disease: A Pictorial Review of Uncommon Locations

Hydatid disease is a zoonotic infection caused primarily by the tapeworm parasite, Echinococcus granulosus. It is considered an endemic disease in the Mediterranean region.  In about 90% of cases, hydatid cysts are found in the liver and lungs; however, any other organ in the body may be affected, particularly in endemic areas. When encountering cystic lesions in these areas, the physician should always keep hydatid disease as a possible diagnosis in mind. To avoid life-threatening conditions such as anaphylactic shock or pressure effect on vital organs, timely diagnosis, and proper management are critical. When a rare site is involved, hydatid disease should be diagnosed using a combination of serologic assays and imaging modalities such as ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI). These imaging modalities can also be used to determine the extent of the disease and assess possible complications. Here, we present a pictorial review of typical imaging manifestations of hydatid cysts in unusual sites. Being aware of these imaging features will assist physicians in making an accurate, timely diagnosis and subsequently, providing optimal management.

Atypical presentations of hydatid cyst in children and their management

Hydatid cyst (HC) is uncommon in children and usually involves a single organ, the lung being the most common site followed by the liver. A series of 18 children who presented with HC at different organs of the body managed at our institute over a period of 5 years is presented here. The clinico-radiological evaluation was done in all patients followed by pharmacotherapy/surgery and was followed up for 2 years. Demographic data, organs of involvement, clinical presentations and investigations, response to oral albendazole therapy, surgical procedures, operative findings, perioperative clinical courses, and surgical outcomes were recorded. The mean age of presentation was 7.7 years with a male:female ratio of 11:7. All patients were symptomatic at presentation and four (22.22%) had atypical symptoms (obstructive jaundice, bladder outlet obstruction, and acute abdominal pain). Liver HC was more common than lung HC. Three patients (16.6%) had synchronous involvement of the lung and liver/spleen. All the patients underwent surgical excision of the cyst as none of them responded to preoperative pharmacotherapy. Open surgery was done in 15 patients and laparoscopic excision was carried out in three (16.6%). Two patients had abnormal communications (cysto-biliary/cysto-bronchial), which were managed successfully. Neither any major perioperative morbidity nor mortality was nor any recurrence was seen in a 2-year clinical follow-up, no significant perioperative morbidity or mortality occurred, and no recurrence was noted. In conclusion, single organ HC is more common in children, with more prevalence of hepatic than pulmonary HC. Early surgical excision of the cyst should be considered (preferably laparoscopic whenever possible) instead of pharmacotherapy.

A giant isolated primary splenic hydatidosis: A case report

Introduction

and importance: Hydatid cyst disease is caused by Echinococcus tapeworm and is one of the major health problems in endemic regions like Nepal. The cases of splenic hydatidosis are quite rare and giant isolated primary splenic hydatidosis is even rarer. The patients present with vague symptoms or no symptoms at all. Here we report a case of isolated splenic hydatid cyst. So, we should think the differential diagnosis of splenic hydatidosis in any abdominal case of endemic regions.

Case presentation

A 27-year-old female presented with left-side abdominal pain for the past 7 months without any particular attraction. Abdominal ultrasound showed a well-defined cystic mass on the upper pole with low-level internal floating debris. Contrast Enhanced CT scan showed well defined cystic lesion measuring about 10.8 × 9.6 × 8.5 cm in the upper pole of the spleen with an exophytic component and minimal homogenous wall enhancement. Laparoscopic Splenectomy was done and albendazole for 3 weeks was prescribed after all the patient was completely normal.

Clinical discussion

In this case, the optimal treatment of giant isolated splenic hydatidosis was splenectomy and prescription of albendazole.

Conclusion

We believe in any abdominal case of the endemic region, the hydatid cyst of the spleen should be taken as one of the differential diagnoses and should be managed appropriately before the complication arises.

A case of giant primary splenic hydatid cyst: Case report

Introduction

Primary splenic hydatidosis is a rare zoonotic disease, common in grazing regions of the world. Primary splenic hydatid cyst is rare and accounts for <2% of patients. Splenectomy is advocated in case of giant hydatid cyst locating in central and hilum area; however, spleen salvaging operations are done in superficial cyst, cysts localized to one pole of the spleen or cysts that are unresectable due to extensive adhesions and in children.

Presentation of case

We present a case of 29-year male patient from rural areas presented with the complain of left hypochondriac pain and tenderness along with the history of farming and cattle raising. There was no other significant history.

Clinical findings and investigations

Physical examination showed mildly distended abdomen, mild tenderness over left hypochondrium. Routine laboratory investigations were sent. Ultrasound and CT scan of the abdomen showed giant splenic cyst measuring approx. 15 × 14 × 11 cm along with daughter cysts. Postoperatively, cyst was sent for histopathological examination.

Intervention and outcome

Preoperatively, vaccinations against Pneumococcus, Hemophilus influenzae and Meningococcus along with Albendazole (15 mg/kg/day) was given 2 weeks before the planned operation. Total splenectomy was performed and diagnosis was confirmed by histopathological examination. Albendazole was continued for 2 more weeks. Patient remains asymptomatic thereafter and regularly followed up in OPD basis.

Relevance and impact

Presence of isolated splenic cyst should raise suspicion for primary splenic hydatid cyst in endemic areas. Splenectomy versus spleen salvaging options should be analyzed and performed as per the indications. Splenic hydatid cyst is one of the rare clinical findings and there is very much high chance that it goes undiagnosed during the clinical practice. So, the main motive behind writing this article is to shed knowledge on basic approach to this splenic finding.

Laparoscopic splenectomy for solitary splenic hydatid cyst: Case report

Hydatid cyst disease is a parasitic disease caused by a type of tapeworm called Echinococcus. It is endemic to cattle-rearing regions of Africa, Asia, South Europe, the Mediterranean, the Middle East and Australia. The most common site of infection is the liver (75%). Involvement of the spleen is rare and occurs in 5% of the cases. Solitary splenic cysts are even rarer (0.5%-4%). We present a case of solitary hydatid cyst of the spleen in a 47-year-old woman. The cyst was asymptomatic and an accidental find on a full-body computed tomography after epileptic seizure and body trauma. The condition was treated successfully with albendazole, but the patient requested the cyst removed. Laparoscopic splenectomy was performed. The specimen was placed in an Endo-Bag and extracted. The patient recuperated well and was discharged on the post-operative day 5. Six months after the procedure, the patient has no complaints.

Isolated Splenic Cystic Echinococcosis and Albendazole hepatotoxicity

Isolated splenic cystic echinococcosis is a rare condition. In Greece the number of cases has declined substantially in the last 20 years. The spleen is the second most common extrahepatic site of cystic echinococcosis. Albendazole is safe, but mebendazole can be used as a substitute, in case of adverse reaction. Our patient was diagnosed with isolated splenic echinococcal cyst, during the investigation for newly diagnosed type 2 diabetes mellitus. We opted for elective splenectomy, based on a risk assessment due to the patient’s working conditions, and treatment with albendazole represented a safety measure until surgery was possible. The patient developed acute hepatocellular injury to albendazole after eight weeks of treatment. This was confirmed through rechallenge with albendazole after discontinuation of the drug. Postsplenectomy the treatment with mebendazole proved to be safe with no adverse reactions. Even though, albendazole is known to be safe, monitoring of hepatic enzymes and full blood count should be offered. In case of toxicities, mebendazole with or without praziquantel can be used. Toxicity to mebendazole can be similar to albendazole but a trial is worthwhile. In our patient, treatment with mebendazole was uneventful

MDCT Findings of Splenic Pathology

The delineation and characterization of splenic lesions and other abnormalities can be challenging on computed tomography. Many splenic lesions are incidentally found, imaging features tend to overlap, and without the appropriate clinical context, differentials can range from benign to malignant. Radiologists should be familiar with the wide variety of pathologies seen on computed tomography as it is often the first imaging modality a splenic lesion is seen. The purpose of this MDCT-focused review is to understand normal splenic anatomy and its variants, to illustrate and describe typical and atypical imaging patters of inflammatory, infectious, vascular, traumatic, benign, and malignant tumors of the spleen and provide clues in reaching the appropriate differential diagnosis and management.

OUP accepted manuscript

Echinococciasis is a zoonotic infection observed in almost every anatomic location in the body. The liver and lungs are the most frequent sites of infection. However, spleen involvement is rare, and isolated splenic hydatid disease is even less common. Herein, we report a case of isolated splenic hydatid cyst without any tissue involvement that was treated with the classical surgical approach.

Cross-sectional imaging findings of splenic infections: is differential diagnosis possible?

The spleen plays an important role in the immunological homeostasis of the body. Several neoplastic and non-neoplastic diseases may affect this organ, and imaging is of fundamental importance for diagnosis. Infectious diseases of the spleen can be encountered in daily radiology practice, and differential diagnosis may sometimes be challenging. Infectious involvement of the spleen can be primary or secondary to a different source outside the spleen. Despite the fact that different infectious diseases may cause similar imaging findings, we believe that differential diagnosis between different causes may also be possible in certain patients with imaging. Early diagnosis may potentially enhance patients’ treatment and outcome. In this review, we aimed to increase imaging specialists’ awareness of splenic infections by describing the multimodality imaging features of common and atypical infections of the spleen with their differential diagnoses.

WFUMB Position Paper-Incidental Findings, How to Manage: Spleen

The World Federation for Ultrasound in Medicine and Biology (WFUMB) is addressing the issue of incidental findings (IFs) with a series of publications entitled "Incidental Imaging Findings-The Role of Medical Ultrasound." IFs are less commonly encountered in the spleen than in many other abdominal organs but remain a frequent dilemma in clinical practice. A histological diagnosis is rarely necessary for patient management. Many IFs, such as secondary spleens and splenic cysts, are harmless and do not require any further investigation. The diagnosis of many other focal splenic lesions is, however, often problematic. The following overview is intended to illustrate a variety of incidentally detected spleen pathologies such as size variants, shape variants, secondary spleens, focal splenic lesions and splenic calcifications. It should aid the examiner in establishing the diagnosis. Moreover, it should help the ultrasound practitioner decide which pathologies need no further investigation, those requiring interval imaging and cases in which immediate further diagnostic procedures are required.

Primary splenic hydatid cyst an unexpected diagnosis: Case report

Introduction

Hydatid disease is endemic in farming areas but occurs worldwide. The most common site of disease is liver. Hydatid disease of the spleen is a rare condition. Worldwide incidence of splenic hydatid is 0.5-4%. Surgery is the mainstay of treatment. The standard treatment is open total or partial splenectomy.

Presentation of case

A 28 year-old female patient was referred to our institution, after coincidental sonography finding. On abdominal examination, there was no sensitization, and there was no resistance or rebound.Ultrasound showed an enlarge spleen; an abdominal CT confirmed the presence of a splenic cyst at the lower pole of the spleen of 7 cm in diameter, no other organ involvement. The biological confirmation was made by indirect hemagglutination. Spleen-sparing surgery was performed. Macroscopic and microscopic examination of the specimen confirmed Hydatid cyst. The patient was discharged from hospital on the seventh postoperative day with a prescription for albendazole (2 × 400 mg/day) for three months.

Discussion and conclusion

The rarity of primary splenic hydatid disease poses a diagnostic challenge for clinicians, the disease should be considered in differential in every patient in endemic areas with cystic lesion of spleen until proved otherwise, it may be detected incidentally or present with non-specific complaints, preservation surgery should always be tried to avoid post splenectomy infection, especially in young patients.

Isolated Giant Primary Splenic Hydatid Cyst in a 10-Year-Old Boy: A Case Report

Hydatid cyst (HD) disease is a parasitic infection produced by cysts containing the larval stage of Echinococcus granulosus. It occurs worldwide, but its prevalence is higher in the rural communities of some developing countries like Yemen, where sheep and cattle raising constitute a crucial component of the agricultural industry. This zoonotic disease spreads due to close contact humans with sheep and dogs. The most involved organs with HC are the liver and lungs. However, other organs may also foster it, such as the spleen, with an incidence rate of between 0.5% and 6%. To the best of our knowledge, primary involvement of the spleen by HC is very rare, and a few cases with isolated spleen HC in children were reported. In this study, a ten-year-old boy with a huge primary splenic HC is reported with chief chief complaint of pain and non-tender bulging in his abdomen’s left upper quadrant. A 20×16×18 cm splenic cystic mass was detected by ultrasonography (US) and confirmed by abdominal computed tomography (CT) scan without macroscopic involvement in other organs. Total splenectomy was carried out for hem. Pathological examinations revealed cystic hydatidosis. We describe this case of an isolated huge spleen HC, which was successfully treated with total splenectomy, focusing on the management and outcome of this disease.

Primitive isolated hydatid cyst of the spleen: total splenectomy versus spleen saving surgical modalities

Background

This study aims to describe the clinical features of the isolated primitive splenic hydatid cyst, discuss and compare the different surgical approaches of this uncommon disease.

Methods

This is a descriptive retrospective study carried out over a period of 7 years extending from January 2013 to December 2019 reporting eight cases of isolated primitive splenic hydatid cysts. Data were collected from the register of the general surgery department of the Jendouba regional hospital. Files concerning another associated hydatid localization were excluded. Four patients underwent total splenectomy and four of them underwent different spleen preserving surgical techniques including resection of the protruding dome, partial splenectomy and pericystectomy.

Results

The diagnosis was incidentally made in 50% of cases. The main other revealing complaints are pain in the left upper quadrant of abdomen in 25% of cases and a painless renitent mass in the same quadrant in only 12,5%. None of patients who underwent total splenectomy had fever or sings of postoperative sepsis. Compared to those who had total splenectomy, patients who underwent spleen preserving surgery had a longer average hospital stay (9 vs 6,25 days) related to post-operative complications including abscess in the residual cavity after protruding dome resection in one patient and post-operative haemorrhage in one patient.

Conclusions

The current case series argues in favor of total splenectomy, preferably by laparoscopic route whenever the technical platform allows it, associated with some specific peri-operative therapeutic measures. It seems to be the safest way that helps to avoid post-operative complications of spleen saving surgical modalities. These complications are usually difficult to manage in poor countries with limited technical resources. Total splenectomy guarantees at least a decreased hospital stay, reduced healthcare costs, and the absence of recurrence in highly endemic underdeveloped countries.

A giant splenic hydatid cyst: Why calcified cysts should not be considered as a dead cyst

Our case report showed that peripheral wall calcification of the hydatid cyst does not mean inactivation of the cyst and calcification of cyst wall may occur in all stages of disease.

Clinical and Laboratory Presentation of Hydatid Disease: A Study From Northeast India

Introduction

Hydatid disease is an immense health problem in developing countries. The diagnosis of hydatid cyst is often difficult because of its protean manifestations. Our objective was to evaluate the various clinical and laboratory presentations of hydatid disease and various modalities of treatment from a tertiary care center.

Materials and methods

We reviewed the clinical and laboratory features of patients presenting with hydatid cyst through retrospective analysis from January 2018 to December 2019 from a tertiary care hospital in northeast India.

Results

Of the 26 adult patients with hydatid cysts who were part of the study, 14 (53.8%) were males and 12 (46.2%) were females. The mean age was 34.6 years. The most common site of involvement was the liver (69%) followed by lung (19.2%) and brain (7.7%). Palpable mass in the right upper quadrant of the abdomen was the most common symptom (88.3%) for liver hydatid cyst followed by pain abdomen (66.6%). Systemic symptoms like fever and weakness were present in most of the patients. The majority of patients (80%) were from rural areas.

Conclusion

Hydatid cysts present with varied symptomatology. History of exposure to infected animals may not be present. A high degree of clinical suspicion combined with meticulous history and clinical examination supported by laboratory investigations are required for its diagnosis.

Primary splenic hydatid cyst treated with laparoscopic spleen preserving surgery: A case report

•

Primary splenic hydatidosis is an uncommon entity.

•

Total splenectomy is considered the standard treatment, but carries multiple risks.

•

Partial splenectomy offers comparable outcomes with reduced morbidity.

•

Partial splenectomy is recommended for simple, single, small, and peripherally located cysts.

•

Laparoscopic cyst unroofing is feasible in treating primary splenic hydatid cysts.

Background

Primary splenic hydatidosis is an uncommon etiology. Total splenectomy has been the treatment of choice, however, spleen preserving surgery has been gaining popularity.

Case Report

We present a case of a 52-year-old man who was evaluated for a splenic cyst, found incidentally on CT scan done at another institution. MRI was repeated in our institution along with an indirect hemagglutination test to confirm the diagnosis. Since our patient had a single non-complicated cyst confined to the spleen’s lower pole, we decided to opt for laparoscopic cyst unroofing and omentoplasty, a spleen preserving technique.

Discussion

Due to the rarity of splenic hydatidosis, no strict management guidelines are available, and the decision is usually left for the surgeon. Total splenectomy has been considered the standard of care, however, spleen preserving surgical techniques and percutaneous interventions have been suggested as better alternatives. Spleen preserving techniques lead to surgical outcomes comparable to total splenectomy, with the added benefit of preserving the immunological protection provided by the spleen and protecting patients from dramatic complications that might follow total splenectomy, such as overwhelming post-splenectomy infections, which are associated with very high mortality.

Conclusion

Laparoscopic cyst unroofing and omentoplasty is a feasible surgical technique to treat primary splenic hydatidosis while preserving the spleen’s immunologic function.

Evaluation the Effects of Eucalyptus Essential Oil and Hypertonic Saline as Scolicidal Agents in Induction of Sclerosing Cholangitis in Rabbits

Background

There are several scolicidal agents for inactivation of hydatid cyst protoscolices during surgery, but most of them are associated with adverse side effects such as sclerosing cholangitis (SC) and liver necrosis. The present study aimed to evaluate the adverse effects of Eucalyptus essential oil to induce SC in animal models.

Materials and Methods

Eighteen rabbits weighting 2000-3500 g were included in three groups for this study. About 0.3 ml of Eucalyptus essential oil (1%), or 5% hypertonic saline, or normal saline was injected for 5 min in the gallbladder. After 4 months, the liver, common bile duct, and duodenum were resected and immediately sent for cholangiography and pathologic studies.

Results

According to pathological studies, inflammation is more common in Eucalyptus and hypertonic saline groups. Due to cholangiographic studies, stricture was slightly higher in the hypertonic saline group than the Eucalyptus group.

Conclusion

Thus, 1% Eucalyptus essential oil is at least as safe as 5% hypertonic saline, but for clinical uses, it must be confirmed with further studies.

Simultaneous Huge Splenic and Mesenteric Hydatid Cyst

Hydatid disease (HD) is caused by Echinococcus granulosus and is endemic in many parts of the world. This parasitic tapeworm can produce cysts in almost every organ of the body, with the liver and lung being the most frequently targeted organs. The spleen and mesentery are unusual locations. We report a case of simultaneous huge splenic and mesenteric hydatid cyst in a 91-year-old male patient. The patient was presented with chronic abdominal pain, increased frequency of defecation, and typical history of animal contact (cattle, sheep, and dogs). After performing imaging studies, he was diagnosed with a simultaneous huge spleen and pelvic mesentery hydatid cyst that was managed surgically by splenectomy, pelvic mesenteric cyst deroofing, and partial cystectomy.

Laparoscopic Management of Initially Unrecognized Splenic Hydatid Cysts: A Case Report and Review of the Literature

We present a case report that demonstrates diagnostic and intraoperative challenges in the laparoscopic management of initially unrecognized splenic hydatid disease. A male patient, aged 44, was admitted to our department with a big unilocular splenic cyst, radiologically (ultrasonography, computed tomography) characterized as a simple cyst. Serological tests for anti-Echonococcus antibody were negative, and chests X-ray findings were unremarkable, so laparoscopic cyst fenestration with omentoplasty was planned. The intraoperative finding did not correspond to a simple splenic cyst. Hydatid daughter cysts were recognized after the careful opening of the cyst wall. The operation was completed without shifting to open procedures. Laparoscopic partial pericystectomy with omentoplasty is a safe and effective surgical procedure for the management of splenic hydatid disease.

Spontaneous rupture of isolated splenic hydatid cyst without acute abdomen: A case report

Isolated splenic hydatid cyst is a very rare manifestation of hydatid cyst. Rarely, patients present late after the cyst is ruptured. They might not present with usual presentations such as the acute abdomen, anaphylaxis, or urticarial rashes but only with a distended abdomen. Splenectomy is the emergency operative management.

Hydatid Cyst of Spleen Presenting with Vague Symptoms: A Diagnostic Conundrum

Hydatid cysts are caused by a tapeworm Echinococcus granulosus. They usually occur in the liver. When occurring in spleen they present with vague symptoms which make it difficult for the physicians to diagnose. We present a case of a 10-year-old male who presented with fever, abdominal pain, and burning micturition along with vomiting. Abdominal exam revealed no visceromegaly. Abdominal ultrasound (US) and computed tomography (CT) scan showed multiple hypoechoic and hypo-dense areas, respectively. Splenic abscess, abdominal tuberculosis (TB), pyelonephritis and malignancy were ruled out with appropriate investigations. The patient was not responding to triple therapy of antibiotics (ceftriaxone, metronidazole, and cloxacillin). A final diagnosis of hydatid cyst of spleen was made when serum echinococcus immunoglobulin G (IgG) antibodies were found to be positive. The patient was treated with albendazole and was discharged on improvement. It is vital to be vigilant and consider echinococcal hydatid cyst as a differential in the lesions of spleen, especially if the patient has a rural background.

Unusual pseudocyst in a wandering spleen

Pseudocysts of the spleen are rare, generally asymptomatic lesions developing secondary to trauma, infection or infarction. When symptomatic, they typically present as non-specific pain in the left hypochondrium, with or without a palpable lump on clinical examination. However, these conventions fail when they occur in a wandering spleen, making imaging critically important. This report describes an unusual case of a 50-year-old who presented with a large cystic mass in a pelvic spleen; imaging facilitated a successful splenectomy and subsequent histopathology revealed a pseudocyst in a wandering spleen.

Labial hydatid cyst - A rare entity

Hydatid cyst is a parasitic infestation by tapeworm Echinococcus. This endemic disease is prevalent in the Middle East and Southeast Asian populations. This zoonotic disease is mainly transmitted by cattle and dogs. Few studies have been reported in the head-and-neck region. There are very few isolated cases have been reported within the oral cavity region. No case until now has been isolated from the labial mucosa. We now present one such case here.

Splenic Cysts: A Strong Indication for a Minimally Invasive Partial Splenectomy. Could the Splenic Hilar Vasculature Type Hold a Defining Role?

BACKGROUND

The aim of the study is to assess the impact of the splenic hilar vasculature configuration on the amount of remnant splenic parenchyma volume after partial splenectomy for splenic cysts.

METHODS

The data of all patients receiving a splenectomy for a splenic cyst from 2002 to 2016 at the Center of General Surgery and Liver Transplantation of Fundeni Clinical Institute were retrospectively reviewed. The size and location in the splenic parenchyma of the cyst and the splenic hilar vasculature type were assessed for each patient with a splenectomy.

RESULTS

Thirty-one patients with non-parasitic and 32 patients with hydatid cysts were recorded. In cases of centrally located cysts, a total splenectomy was performed for the majority of cases, while in peripheral cysts a spleen-preserving surgery was feasible for most of the patients (p = 0.001). The size of the cyst was significantly higher in the group of patients with a total splenectomy, compared with the group with a partial splenectomy (p = 0.003). In the subgroup with a distributed arterial pattern, preservation of more than 50% of the initial parenchyma was achieved in a significantly higher proportion of patients, compared with the subgroup of patients with a magistral pattern (p = 0.012).

CONCLUSION

Besides cyst size or peripheral location in the splenic parenchyma, the vascular pattern is also considered another decisive factor that associates with successful conservative or minimally invasive approach.
