Splenic torsion, a challenging diagnosis: Case report and review of literature

Wandering spleen combined with pedicle torsion and splenic infarction: a rare case report and literature review

Wandering spleen (WS) concurrent with splenic pedicle torsion and infarction has been described rarely. We reported our experience in diagnosing and treating such a condition in a 16-year-old girl with acute abdominal pain. A plain CT scan showed the wandering of the spleen from the left upper quadrant. Contrast-enhanced CT indicated dilatation and distortion in the splenic vein, a counterclockwise "whirl sign" in the splenic pedicle, pancreatic tail torsion, and splenic infarction. The patient was diagnosed with WS combined with splenic pedicle torsion and splenic infarction and underwent splenectomy for treatment. She showed a satisfactory outcome during the follow-up. To enhance our understanding of it, we performed a comprehensive literature research to summarize the clinical manifestations, treatment options, and outcomes among adolescent patients.

Imaging Features of Uncommon Entities That Manifest with Torsion

Torsion is the twisting of an object along the axis, and various structures (organs and tumors) in the body can twist. Torsion causes initial lymphatic and venous outflow obstruction, leading to congestive edema, enlargement, venous hemorrhagic infarction, and surrounding edema. It can also cause subsequent arterial obstruction depending on the degree of torsion, leading to ischemia, infarction, necrosis, gangrene, and surrounding inflammation. Therefore, in several cases of torsion, immediate surgical intervention is required to improve blood flow and prevent serious complications. Clinical manifestations of torsion are often nonspecific and can affect individuals of varying ages and sex. Imaging plays an important role in the early diagnosis and management of torsion. Multiple imaging modalities, including US, radiography, CT, and MRI, are used to evaluate torsion, and each modality has its specific characteristics. The imaging findings reflect the pathophysiologic mechanism: a twisted pedicle (whirlpool sign), enlargement of the torsed structures, reduced blood flow, internal heterogeneity, and surrounding reactive changes. The whirlpool sign is a definitive characteristic of torsion. In some cases, despite poor internal enhancement, capsular enhancement is observed on contrast-enhanced CT and MR images and is considered to be associated with preserved capsular arterial flow or capsular neovascularization due to inflammation. Radiologists should be familiar with the pathophysiologic mechanisms, clinical characteristics, and imaging characteristics of torsion in various structures in the body. Since other articles about common organ torsions already exist, the authors of this article focus on the uncommon entities that manifest with torsion. ©RSNA, 2024.

Wandering spleen with acute torsion mimicking an adnexal mass

Wandering spleen manifests when the splenic ligaments are underdeveloped, or become lax, thereby allowing the spleen to relocate from its anatomical site to more distant areas. During such movements, torsion of the long splenic peduncle is common, which can lead to symptoms of acute abdomen and further complications such as infarction. It is typically seen in children and young females. Our report presents a case of a 22-year-old female presenting to the ER with complaints of severe pain in the abdominal region. On ultrasound, there was suspicion of an adnexal mass, which was later confirmed to be a misplaced spleen in the lower abdomen, with torsion, fat stranding, and splenic vein thrombosis, as revealed by enhanced CT abdomen and pelvic MRI. It was followed by an emergency splenectomy. As wandering spleen presents nonspecifically and is a rare condition, it is important to consider wandering spleen when patients present similarly to this case, to prevent misdiagnosis and to deliver surgical treatment quickly to preserve the spleen.

Wandering spleen causing small bowel obstruction: Laparoscopic surgical treatment (with video)

INTRODUCTION

Wandering spleen (WS) is a clinical entity in which the spleen is not located in its normal anatomical site. Few cases have been reported, mainly in women of childbearing age. This condition can be congenital or acquired due to excessive elasticity of the spleen's suspensory ligaments. WS may cause acute complications requiring emergency surgery, especially related to the rotation of its vascular pedicle, leading to chronic or acute ischemia. The aim of the present case is to show a rare complication of WS, small bowel obstruction (SBO), and its management.

PRESENTATION OF CASE

We report the case of a 40-year-old female presenting with abdominal pain, nausea, and vomiting. CT scan showed SBO caused by WS located in the pelvis with an enlarged spleen vascular pedicle (SVP). Laparoscopic exploration, splenectomy, small bowel resection and anastomosis were performed.

DISCUSSION

WS may cause chronic or acute complications, mainly linked with enlargement and torsion of SVP, including acute ischemia and spleen necrosis, or compression of the near organs such as small intestine, stomach, pancreas. The diagnosis is based on physical examination, CT scan and blood exams. Generally, the WS's treatment is laparoscopic splenectomy or splenopexy. In case of vital spleen, splenopexy can be performed, in case of not vital spleen, splenectomy should be preferred.

CONCLUSION

This case provides an excellent example of SBO related to WS. In the video, the management of this complex situation is shown. In these cases, splenectomy represents a valuable option.

Splenic torsion, a challenging diagnosis in an adult presenting with acute abdomen

INTRODUCTION

Wandering spleen (WS) is a rare condition, occurring in only 0.2 % of cases, where the spleen becomes hypermobile due to the absence or laxity of its anchoring ligaments. Torsion of the spleen, primarily seen in children but occasionally in adults, is a critical complication that can lead to infarction and is considered a medical emergency.

CLINICAL PRESENTATION

We present a case report of a 50-year-old woman with type 2 diabetes and psychiatric illness presented with 2 days of vomiting, abdominal pain, and dehydration. Physical examination showed a tender mass in the abdomen and imaging confirmed a twisted spleen with a thrombosed splenic vein, leading to a successful emergency splenectomy. The patient had an uncomplicated recovery and was discharged with post-splenectomy protocol.

DISCUSSION

Splenic torsion, a rare occurrence primarily observed in children. Clinical diagnosis is aided by palpable abdominal masses and confirmed by radiological imaging. The gold standard diagnostic tool is contrast-enhanced computed tomography (CT), whereas Ultrasonography (USG) is equally good in early assessment. Early identification is crucial to salvage the spleen. Management options include detorsion, splenopexy, or splenectomy depending on the organ viability. Elective splenopexy has emerged as a proactive measure, particularly in children, to prevent complications.

CONCLUSION

Splenic torsion is a rare but important differential diagnosis in patients presenting with acute abdomen. Early diagnosis and prompt management is necessary to preserve the spleen and to prevent the development of complication. Surgery is often necessary and either splenopexy or splenectomy should be done.

IMAGING MANIFESTATIONS OF WANDERING SPLEEN WITH TORSION

BACKGROUND

A wandering spleen (WS) is a rare clinical entity characterized by a spleen located in the lower part of the abdomen or the pelvic cavity rather than the normal anatomical site. The complications of a wandering spleen include splenic torsion, splenic infarction, and adjacent visceral injury.

CASE REPORT

We present a case of a male patient admitted to the emergency department with vomiting, nausea, and persistent lower abdominal pain. Computed tomography and ultrasound were performed and were used to diagnose a wandering spleen with torsion leading to splenic infarctions. Subsequently, laparoscopic surgery and pathology confirmed this diagnosis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Ultrasound and computed tomography scans play a significant role in diagnosing WS and its complications, allowing an emergency physician to establish treatment options for WS.

Wandering Spleen with Splenic Torsion: Unusual Cause of Acute Abdomen

INTRODUCTION

Wandering spleen is a rare condition characterised by laxity or lack of splenic ligaments as a result of acquired or congenital causes. There is a possibility of misdiagnosis due to its vague symptoms. In order to make a proper diagnosis, imaging techniques including abdominal ultrasonography and CT scanning are essential. Surgery is the main option of management. If the spleen is viable and there is no thrombosis in the splenic veins, splenopexy is the preferred surgical procedure. Alternatively, splenectomy plus prophylactic antibiotic and vaccination usage may be employed if spleen has infarction.

CASE PRESENTATION

A 12-year-old male child who had previously experienced constipation, mucoid diarrhoea, and abdominal distention arrived with crampy abdominal pain that had lasted for four days. The patient was tachycardic with abdominal tenderness. Whirlpool sign and lack of a spleen in its normal position were visualized on an abdominal ultrasound. The spleen was located intraoperatively in the lower abdomen, adhered to the ileum and appendix. It was 720° twisted and had necrotic areas. The patient underwent an appendectomy with splenectomy with a smooth post-operative course; combination meningococcal and pneumococcal vaccines were administered; and antibiotic prophylaxis was started for the patient.

CONCLUSION

High clinical suspicion and the use of imaging modalities like ultrasound and CT scan are extremely crucial to diagnose wandering spleen and perform splenic salvage surgery because its clinical diagnosis is challenging.

Wandering small intestinal stromal tumor: A case report

BACKGROUND

The occurrence of gastrointestinal stromal tumors (GISTs) in the small intestine is rare, and a case of wandering small intestinal stromal tumor has been rarely reported to date. Dissemination of this case can help inform future diagnosis and effective treatment.

CASE SUMMARY

A 68-year-old patient presented to us with tarry stools. Computed tomography showed a mobile tumor moving widely within the abdominal cavity. As the laboratory data showed a low range of red blood cells and an immediate surgery was not indicated, we performed digital subtraction angiography and embolization to achieve hemostasis. Surgical resection was performed after the patient’s condition improved. The tumor was successfully removed laparoscopically. Histological examination revealed submucosal GIST with infarction, which was of intermediate-risk, with mitotic count < 1 per 10 high-power field. Immunohistochemical studies revealed the following: CD117+, Dog1+, CD34+, SMA+, S100-, CK-, Des-, SOX-11-, STAT6-, Ki67 Hotspots 10%+. The patient was ultimately diagnosed with wandering small intestinal stromal tumor.

CONCLUSION

When a highly vascularized tumor is clinically encountered in the small intestine, the possibility of stromal tumors should be considered. However, when the tumor cannot be visualized at its original location, the possibility of tumor migration is considered.

Wandering spleen with torsion and infarction: A case report

Wandering spleen, also known as ectopic spleen, is a rare condition in which the spleen's anatomical location is other than its fixed position in the abdomen's left upper quadrant. The cause of such an abnormality could be due to congenital or acquired factors, which could ultimately lead to torsion and splenic infarct. Given the nonspecific clinical symptoms and the potential complications associated with wandering spleen, computed tomography scans provide a crucial means for proper diagnosis. In this article, we report the case of a 16-year-old female with a diagnosis of wandering spleen with torsion and splenic infarct.

Surgical Management of a Volvulus of a Wandering Spleen Associated with a Volvulus of the Small Intestine

Introduction

A wandering spleen is a rare anatomical condition characterized by a free-floating splenic tissue that is not located in its normal position in the left upper quadrant. This condition is usually asymptomatic but can also manifest itself with volvulus of the spleen and consequent infarction and necrosis of the parenchyma, requiring an urgent surgical management. Additionally, a wandering spleen can be associated with other contemporaneous anatomical anomalies. Case Presentation. We report a case of a 21-year-old woman, admitted to our hospital for intense abdominal pain and vomiting. A CT scan revealed a wandering spleen in the mesogastric area with the spleen torted on its axis, associated with a volvulus of the small intestine. Abdominal exploration revealed a macroscopically normal free-floating spleen attached to an abnormally long vascular pedicle. The management of the wandering spleen was conservative, and a splenopexy was performed.

Conclusions

The torsion of the wandering spleen constitutes an infrequent but life-threatening abdominal emergency. The diagnosis of the wandering spleen is frequently challenging since clinical findings are usually not specific. Imaging such as computed tomography scan plays an important role in the differential diagnosis pathway. Treatment should be planned according to the splenic parenchyma conditions. Splenectomy is indicated when massive infarction and thrombosis of splenic vessels have occurred. When splenic parenchyma is not compromised, it is preferred to perform a conservative surgical technique, such as splenopexy, in order to avoid postsplenectomy complications.

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.

Wandering Spleen: A Rare Case of an Adnexal Lesion

The wandering spleen (WS) is a rare condition in which the spleen is not found in its usual location in the left hypochondrium but is positioned in the lower abdomen or the pelvis. This is a case of a 21-year-old woman who presented with chronic, intermittent, and subtle pain in the left lower quadrant of her abdomen. After clinical examination and ultrasound evaluation, an adnexal lesion was detected in the left lumbar area, and no splenic tissue was found in the left hypochondrium. The wandering spleen should be included in the differential diagnosis when encountering a patient with non-typical or acute abdominal pain. Accurate diagnostic evaluation can be performed with low-cost imaging modalities such as Doppler ultrasound.

Torsion of spleen and portal hypertension: Pathophysiology and clinical implications

The displacement of spleen from its normal location to other places is known as wandering spleen (WS) and is a rare disease. The repeated torsion of WS is due to the presence of long pedicle and absence/laxity of anchoring ligaments. A WS is an extremely rare cause of left-sided portal hypertension (PHT) and severe gastric variceal bleeding. Left-sided PHT usually occurs as a result of splenic vein occlusion caused by splenic torsion, extrinsic compression of the splenic pedicle by enlarged spleen, and splenic vein thrombosis. There is a paucity of data on WS-related PHT, and these data are mostly in the form of case reports. In this review, we have analyzed the data of 20 reported cases of WS-related PHT. The mechanisms of pathogenesis, clinico-demographic profile, and clinical implications are described in this article. The majority of patients were diagnosed in the second to third decade of life (mean age: 26 years), with a strong female preponderance (M:F = 1:9). Eleven of the 20 WS patients with left-sided PHT presented with abdominal pain and mass. In 6 of the 11 patients, varices were detected incidentally on preoperative imaging studies or discovered intraoperatively. Therefore, pre-operative search for varices is required in patients with splenic torsion.

Infarcted wandering spleen: A case report from Saudi Arabia

Spleen is normally positioned in the left upper quadrant. Abnormal location where it is not found in its normal anatomical position is called wandering spleen (WS). Wandering spleen is a rare medical condition that occurs due to developmental abnormality or acquired laxity of the ligaments that hold the spleen in its normal anatomical position. It affects children and young adults, especially childbearing age women. Patients affected with this condition may present with nonspecific symptoms requiring a high index of suspicion. Here, we are presenting a 20-year-old female known to have WS ended up with infarcted WS requiring emergency splenectomy.

'Wandering spleen with acute torsion' : a rare indication for splenectomy in an adult, complicated by postoperative splanchnic venous thrombosis and intestinal gangrene

Wandering spleen (WS) is a hypermobile spleen that, due to the laxity of its ligaments, is prone to torsion. We report a case of a 45-year-old multiparous woman who presented with acute abdominal pain and a tender palpable mass. A contrast-enhanced computed tomography scan of the abdomen showed a WS with torsion. She underwent an emergency splenectomy and was discharged after an uneventful recovery. She was readmitted with splanchnic venous thrombosis and was managed with therapeutic low-molecular-weight heparin (LMWH) and discharged. Twenty days later, she presented with new-onset abdominal pain. She had not complied with LMWH as advised. The thrombosis had progressed, leading to small bowel gangrene, requiring resection and a stoma. Due to frequent metabolic disturbances, an early reversal of stoma was performed. She was lost to follow-up thereafter. This case highlights a rare indication for emergency splenectomy and one of its major postoperative complications.

Case Report: Conservative Non-operative Management of a Neonate With Torted Wandering Spleen

BACKGROUND

The management of wandering spleen (WS) with torsion, a rare pathological condition, is currently unclear. Most patients with this disorder are treated with surgical interventions, such as splenectomy or splenopexy.

CASE PRESENTATION

A newborn female presented with low hemoglobin (10.8 mg/L) and high total serum bilirubin (193 μmol/L) at 3 h of life. A palpable mass was observed during her physical examination, and a magnetic resonance imaging scan of the abdomen confirmed the presence of an infarcted WS with torsion. Upon conservative management with oral antibiotic prophylaxis, careful observation, and repeated follow-ups, the infant remained clinically stable. At 2 years of age, she had normal complete blood count, and a repeat technetium study revealed two splenunculi/splenules in the splenic bed.

CONCLUSION

Most patients with WS are treated surgically with splenectomy or splenopexy. Non-operative management may be a feasible treatment option in select cases with infarcted WS and may allow the natural process of autosplenectomy to occur.

Endoscopic full-thickness resection of gastric ectopic splenic nodules

Background

Ectopic spleen is extremely rare. Most cases are congenital, acquired ectopic spleen may be a consequence of surgery or trauma to the spleen. The ectopic spleen in the gastric wall we reported is even rarer.

Case presentation

We report a 41-year-old female patient, with a past history of splenectomy, who presented with heartburn. Gastroscopy revealed a swelling in the fundus in the stomach. Ultrasonography and computed tomographic examination suggested the possibility of gastrointestinal stromal tumor. We performed endoscopic resection of the mass. Pathological examination of the resected mass showed ectopic spleen.

Conclusion

When a patient with a history of splenectomy presents with a gastric submucosal tumor, ectopic spleen should also be considered in the differential diagnoses. And minimally invasive endoscopic treatment can achieve the purpose of diagnosis and treatment for unobvious submucosal tumors.

Treatment of a congenital diaphragmatic hernia with associated wandering spleen: Case report of a 17-year-old girl

•

Wandering spleen with an associated congenital diaphragmatic hernia is an extremely rare diagnosis.

•

Clinical diagnosis is unlikely, making computed tomography the diagnostic test of choice.

•

Prompt surgical management is required given the risk of significant morbidity associated with both conditions.

Introduction

A congenital diaphragmatic hernia (CDH) is rarely diagnosed in adults and can allow passage of abdominal viscera into the chest cavity. A particularly rare association is a wandering spleen due to absence of its diaphragmatic and retroperitoneal attachment which predisposes to elongation of the vascular pedicle with risk of torsion, infarction and rupture.

Presentation of case

A 17-year-old girl presented with a two-day history of increasing abdominal pain. Examination identified an abdominal mass. Computer tomography (CT) chest, abdomen and pelvis revealed a significantly enlarged wandering spleen with signs of torsion and an associated large left CDH with viscera in the chest cavity. The patient proceeded to an open splenectomy and repair of CDH. Post-operatively the patient developed ileus and required a temporary chest tube for pneumothorax, but otherwise progressed well.

Discussion

Untreated CDH with a symptomatic wandering spleen is an extremely rare diagnosis with only one similar previous case report. Clinical detection is unlikely, making CT scanning the diagnostic test of choice. Surgery is recommended given the high morbidity and mortality of associated complications of both conditions. Splenic preserving options are favoured, however the majority of identified cases require splenectomy because of associated torsion or splenomegaly. Reduction of the CDH should be performed with primary closure of the defect and mesh reinforcement where possible.

Conclusion

CDH with associated wandering spleen in adults presents an extremely rare but clinically important diagnosis. Prompt surgical management as reported in this case should be performed to minimise immediate and future complications.

Wandering spleen with splenic torsion in a toddler: A case report and literature review

RATIONALE

Wandering spleen (WS) is a rare clinical entity characterized by splenic hypermobility caused by absent or abnormal laxity of the suspensory ligaments, which fix the spleen in its normal position. Due to abnormal attachment, the spleen is predisposed to torsion and a series of complications. Pediatric WS is mostly reported in children aged <10 years, especially among infants aged <1 year; it is uncommon among toddlers between 1 and 3 years. To the authors' knowledge, only seven cases of WS have been described previously. Herein, we present the case of a 3-year-old toddler with WS and splenic torsion.

PATIENT CONCERNS

A 3-year-old boy was presented to the pediatric emergency room with a 2-day history of abdominal pain and vomiting. The ultrasonographic examination revealed a mass in the left upper abdomen cavity and absence of spleen in its normal position. Computed tomography showed an enlarged displaced spleen occupying the left abdomen cavity with an elongated splenic vascular pedicle (whirl sign), suggesting splenic torsion.

DIAGNOSES

The patient was diagnosed that had WS and splenomegaly, with or without complications due to splenic torsion.

INTERVENTIONS

The patient underwent emergency laparotomy and splenectomy due to nonviability after detorsion.

OUTCOMES

The postoperative course was uneventful, and the patient was discharged on the 7th day postoperatively without complications. The patient had favorable outcome over a 1-year follow-up.

LESSONS

Herein, we reported the case of a toddler with WS with splenic torsion. Moreover, after reviewing relevant studies in literature, we presented our findings on the diagnosis and treatment of toddlers with WS. Toddlers with WS are characterized by acute abdominal pain, unclear history description, examination restrictions, and high rates of life-threatening complications. High level of suspicion, careful physical examination, detailed history collection, and objective investigation are crucial in the management of toddlers with WS.

Wandering spleen: a rare complication of sleeve gastrectomy

The spleen is an intraperitoneal organ typically located in the left upper quadrant. Ectopic ('wandering') spleen refers to the displacement of the spleen from its normal anatomical location to another region in the abdominal cavity or pelvis. It's a relatively rare condition with no clear aetiology. We present, here, a case of a wandering spleen following sleeve gastrectomy in a 23-year-old female patient, whose spleen, prior to this event, was demonstrated by imaging in a normal anatomical position. A splenectomy was performed, and after an uneventful postoperative period, the patient was discharged. No similar case description was found in the relevant medical literature. Possible causes and decision-making process are discussed. We conclude that the wandering spleen phenomenon should be considered in the differential diagnosis of patients presenting with abdominal pain and new abdominal mass following sleeve gastrectomy.

The Importance of Recognizing Wandering Spleen as a Cause of Recurrent Acute Pancreatitis

Wandering spleen, as its name suggests, is a rare condition where the spleen wanders in the abdomen and is most commonly found in the inferior quadrant as a palpable mass. It can have varying presentations and commonly presents as splenic torsion and very rarely as acute pancreatitis. It is imperative not to miss this diagnosis as it can lead to life-threatening complications in the form of splenic torsion/infarction. Here we describe a rare manifestation of wandering spleen where a young female presented with recurrent episodes of acute pancreatitis.
