Cystic lymphangiomas: CT diagnosis and thin needle aspiration

Acquired cryptorchidism: an unexpected consequence of inguinoscrotal lymphatic malformation treated with Eppikajutsuto

Lymphatic malformation (LM) that causes inguinoscrotal swelling is extremely rare. Surgery, sclerotherapy and pharmacotherapy have been reported as possible treatment options for LM. Recently, Eppikajutsuto (TJ-28), a traditional Japanese herbal medicine has emerged as therapeutic option for LM. We report the case of a 2-year-old boy who presented with a left inguinoscrotal swelling, which was diagnosed as retroperitoneal LM extending into the left scrotum. The surgical approach was less favourable, given the risk of damaging the testicular vasculature or the spermatic cord. Therefore, the patient received medical treatment with TJ-28. As a result, a volume reduction of 83% was obtained, as well as the unexpected consequence of the left testicle retracting into the inguinal area. Laparoscopic exploration was performed and a small bulge on the internal inguinal ring was detected. The patient's acquired cryptorchidism was subsequently treated by orchidopexy.

A rare case of retroperitoneal lymphangioma in a 74-year-old Chinese male

Retroperitoneal lymphangioma is an uncommon and benign mesodermal tumour that arises from the retroperitoneal lymphatics. Notably, it is a rare occurrence in adults, where <200 adult retroperitoneal lymphangioma cases have been published in the literature. Additionally, retroperitoneal lymphangioma is often difficult to diagnose preoperatively and formal diagnosis is frequently determined following surgical exploration. Here, we describe a rare case of retroperitoneal lymphangioma in a 74-year-old man who presented with a 6-month history of intermittent fresh per rectal bleeding with an incidental non-tender left iliac fossa firm mass on examination. Computed tomography scan established a retroperitoneal cystic lesion abutting the aorta and left common iliac vessels. Surgical exploration revealed a large cystic mass and a clean plane of dissection was performed, where the mass was completely excised with all the key structures preserved. Histology was consistent with a retroperitoneal lymphangioma.

Cystic Hygroma of the Breast: A Rare Lesion

Lymphangiomas are congenital malformations of lymphatic vessels. More than 50% of these lesions are present at birth; 90% are diagnosed by the age of 2. These lesions do not expand very rapidly but they tend to infiltrate surrounding tissues; their degeneration into malignant tumors is an extremely rare occurrence. They are mostly located in the neck region and the axilla; breast lymphangioma is very rare. Surgery is usually performed for aesthetic reasons and in order to make a differential diagnosis with other, more common lesions. The surgical procedure involves the excision of the mass; other methods, such as radiotherapy and sclerotherapy, have proved to be completely ineffective.

Correlative imaging of cystic lymphangiomas: ultrasound, CT and MRI comparison

BACKGROUND

Cystic lymphangioma is a rare benign lesion derived from the detachment of the lymph sacs from venous drainage systems; the treatment of choice is a surgical excision and the final diagnosis is of histological type.

PURPOSE

To compare the results of ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI) in patients with cystic lymphangioma to clearly evaluate the anatomic as well as the structural lesion features necessary for differential diagnosis and for the patient treatment planning.

MATERIAL AND METHODS

We analyzed the imaging results of six patients admitted in our department to evaluate cyst-like tumor masses clinically palpable or detected by US. All the patients underwent US, CT, and MRI. The pathology reports demonstrated a mesenterial cystic lymphangioma in five cases underwent surgical resection and in the last case a chest cystic lymphangioma underwent a fine needle aspiration biopsy (FNAB).

RESULTS

In all the cases, the results of US, CT, and MRI were concordant showing cyst-like tumor masses in the abdomen (n = 5) and chest (n = 1) ranging in size from 3.5 to 15 cm.

CONCLUSION

According to our experience, we suggest that the appropriate diagnostic imaging protocol in patients with cystic lymphangioma should initially include the US study and followed by a MRI scan with contrast administration. CT should be avoided because of radiation exposure. US and MRI may also be useful in the follow-up of patients who refuse surgical resection or in whom surgery is contraindicated or postponed as well as to early detect a possible disease relapse.

Dumbbell-shaped lymphangioma of neck and thorax

Vascular malformations consist of a spectrum of lesions involving all parts of the body. They have different terminologies like vascular tumors, vascular malformations, vascular anomalies, and so on, which create a lot of confusion in understanding and treating these pathologies. Of late, classification on the basis of cellular kinetics and clinical behavior has been devised. Hemangioma is the most common vascular tumor. Vascular malformations are of either lymphatic or capillary and venous origin. Sometimes they are of a mixed origin. Lymphangiomas are common in the face and neck area. They are also not unusual in the mediastinum. We present a case where a huge lymphangioma occupied the right supraclavicular area of the neck, extending to nearly the entire right thoracic cavity, compressing the whole lung. The patient had occasional symptoms of cough. Ultrasonography (US) and computed tomography (CT) images clearly described the lesion as cystic, occupying both the supraclavicular and thoracic cavity compressing the lung parenchyma. Surgical excision was planned and we approached the lesion via both cervical and thoracotomy incisions. Complete excision was done, and the lung expended fully after the surgery.

Bilateral renal lymphangiomatosis: imaging and histopathologic findings

Renal lymphangiomatosis is an extremely rare disease characterized by developmental malformation of the lymphatic system surrounding the kidneys. We present the case of a 22-year-old pregnant female discovered because of worsening. Ultrasound, computed tomography, and magnetic resonance imaging studies were performed. An 18 × 11 × 10 cm voluminous cystic subcapsular lesion compressing the left kidney and subcapsular cysts of the right kidney were found. After the delivery, marsupialization was performed and the pathological analysis confirmed the diagnosis of lymphangiomatosis. A review of the literature is proposed.

Computed tomography findings in bilateral perinephric lymphangiomatosis

Perinephric lymphangioma is rare disorder that may be confused with various forms of renal cystic diseases and urinomas. In this disorder a developmental malformation results in failure of developing lymphatic tissue to establish normal communication with the rest of lymphatic system. Once there is restricted drainage of lymphatic fluid the lymphatic channels dilate to form cystic masses that may be unilocular or multilocular and may be seen unilaterally or bilaterally .This condition presents with various signs and symptoms or can be just an incidental finding which in presence of misleading clinical history may be confused with other diseases. CT scan with delayed cuts and USG guided aspiration with biochemical analysis of fluid will help us in arriving to final diagnosis.

Huge cystic lymphangioma involving the entire breast

We report a case of a 31-year-old female who required mastectomy with the diagnosis of cystic lymphangioma of the entire left breast. We tried operative management that is not mastectomy since it was not malignant, but finally mastectomy was needed. In reduction mammaplasty patients, plastic surgeons should consider cystic lymphangioma as a differential diagnosis of unilateral large breasts.

Laparoscopic excision of a retroperitoneal cystic lymphangioma: an insidious case

Cystic lymphangioma is a rare, benign malformation of the lymphatic system. In this paper, we describe a rare case of a retroperitoneal cystic lymphangioma in a 25-year-old woman.

Retroperitoneal lymphangioma

Lymphangiomas are rare cystic tumours that may present as cystic masses in the retroperitoneum. Retroperitoneal lymphangiomas account for approximately 1% of all lymphangiomas. Confusion with other cystic tumours of the retroperitoneum including those arising from the liver, kidney and pancreas is common. A case of a retroperitoneal cystic lymphangioma occurring in a 41-year-old woman raising interesting diagnostic and management issues is reported. The patient presented with vague abdominal pain and persistent nausea. Radiological imaging demonstrated a large multiloculated thin-walled cyst involving the upper retroperitoneum. Surgical resection was complete, revealing a benign cavernous lymphangioma. The patient made a complete recovery and was disease-free 30 months postoperatively.

Lymphangiomas of the ileum: a report of two cases and a review of the literature

Lymphangiomas of the gastrointestinal tract are seen very rarely, especially in adults. We herein present two cases of ileal lymphangioma which were found during surgery. One case was a 43-year-old man with a palpable mass, and the other was a 19-year-old man who presented with symptoms of pyloric stenosis. Although radiologic studies helped us, we could only be certain about the diagnosis after both the operation and histopathologic studies. We performed a total excision with ileal resection in both cases.

Cystic retroperitoneal lymphangiomas in adults

Lymphangioma (LA) is a rare benign tumour of the lymphatic tissue, most common in the neck and head, and clinically manifests itself mostly in childhood. Within this group, intra-abdominal and retroperitonal LA are the rarest tumours, especially when occurring in adults. We report four LAs localized in the retroperitoneum of patients aged between 28 and 72 years. One of these tumours infiltrated the transverse mesocolon and greater omentum, others were situated in the left retroperitoneum and retroperitoneally at the duodeno-jejunal flexure, and in the retrosplenal and retropancreatic area. Diagnosis was made by light microscopy supported by immunohistochemistry. In three cases the tumour could be removed by radical surgery and none of these patients had a recurrence (median follow-up time: 4 years). The tumour could not be removed completely from one patient with pre-operative chylascos. Six months after diagnosis of LA this patient died of cardiopulmonary failure due to progressive tumour chylascos. Isolation and ligation of the cystic LA's peduncle as well as ligation of lymph channels can prevent recurrences and chylascos.

Identification and surgical management of cystic retroperitoneal lymphangioma in children

Retroperitoneal lymphangiomas are rare, benign cystic structures that are best evaluated with computed tomography and ultrasound. Preoperative diagnosis is often difficult, in part because there is little to distinguish them from other cystic masses and because the lesion is often not considered on the differential diagnosis. Surgery may be required as both a diagnostic and therapeutic measure. The cysts may be asymptomatic for years and then present because of compression of surrounding structures or pain. The treatment is as complete surgical excision as is possible. Bowel cleansing should be done preoperatively. The long-term results are excellent when total excision or near-total excision with marsupialization is accomplished.

Retroperitoneal cystic lymphangioma

Two cases of retroperitoneal cystic lymphangioma (CL) are presented; the current literature on this rare, benign neoplasm of the lymphatic system is reviewed. This tumor consists of various numbers of cyst-like cavities filled with a serous, serosanguineous or chylous fluid. The histogenesis of CL is still uncertain. Most commonly CL occurs in the neck and in the axillary region, whereas it is rare in the retroperitoneum. Although retroperitoneal CL is a benign lesion, it may cause significant morbidity due to its large size, and its often invasive character with a strong tendency to secondary infection. The treatment of choice is surgical excision.

Lymphangioma of the diaphragm (first case report)

Intraabdominal cystic lymphangioma occurs rarely, and lymphangioma of the diaphragm has not been previously reported in the literature. The authors herein report the clinical features, radiographic findings, and treatment of one encountered case of lymphangioma of the diaphragm.

Retroperitoneal cystic lymphangioma diagnosed by computerized tomography, magnetic resonance imaging and thin needle aspiration

We report a case of retroperitoneal cystic lymphangioma presenting with right pack pain. Although preoperative diagnosis is usually difficult in such a rare condition, we could make the preoperative diagnosis on grounds of the peculiar findings obtained by computerized tomography (CT), magnetic resonance imaging (MRI) and needle aspiration.

Abdominal cystic lymphangiomas: US and CT findings

We retrospectively analyzed six cases of abdominal cystic lymphangiomas (CL), who had undergone surgical resection. These cases had been evaluated by several modalities: ultrasonography (US), computed tomography (CT), angiography and fine needle aspiration. No age predilection was found. All patients were symptomatic. The most common presenting symptoms were abdominal pain (66%), palpable mass (66%), fever (50%) and vomiting (30%). US showed septations (85%) and unicameral mass (15%); in three cases (50%) echogenic material within the cyst was found, probably due to hemorrhage and infection. CT showed capsular enhancement in all cases. Capsular and septation thickness were slightly increased in cases of infection or bleeding. At CT the contents were usually of fluid attenuation (66%); in 33% the attenuation values were higher, probably because of internal bleeding and infection. US was superior to CT in the demonstration of septations and the internal nature of the cysts. The major role of imaging is to demonstrate the cystic nature of these abdominal masses, because they do not have specific signs or symptoms that could allow a clinical diagnosis.

Cystic lymphangioma and plunging ranula treated by OK-432 therapy: a report of two cases

Among head and neck angiotumors, cystic lymphangioma occurs in infancy in most cases and it is rare in adulthood. Plunging ranula is one of the diseases which need to be distinguished from lymphangioma, though operation is the first choice therapy for both of these. In the present study, we report on 2 cases in whom we conducted intralesional injection of OK-432 for cervical lymphangioma and ranula found in 20 and 35 year-old female patients. We obtained excellent improvement. First of all, we punctured the tumors and sucked out the liquid content as much as possible, and then used OK-432 in the same volumes to those drawn out. No swelling was observed in either patient after 1 month, and cysts disappeared in CT 4 and 12 months after injection, respectively; at present, the prognosis is satisfactory, without recurrence. The intralesional injection of OK-432 is considered an effective method, as the speed of complete disappearance by this therapy is high. Cosmetically it is superb, leaving no lesions in the skin of the injection site.

CT differentiation of large abdominal lymphangioma from ascites

Abdominal lymphangiomas are uncommon benign tumors, usually presenting in early childhood as a palpable abdominal mass. Their sonographic and CT appearance has been well described, and usually consists of well-defined, thin-walled cysts which can be unilocular, or multiloculated, and may contain septations. Rarely, these cysts may be large enough to be confused with ascites on physical exam. We present such a case to emphasize the imaging features that may help in the differentiation between ascites and large mesenteric lymphangiomas.

Computed tomographic findings in two patients with vascular hamartomas

The clinical, computed tomographic (CT) and histological findings of two patients with vascular hamartomas are presented. The appearances on CT of the two lesions were markedly different. Although both lesions were histopathologically benign, one showed a more disorganized architecture on histology and clinically behaved in a more aggressive manner. The CT findings in this case reflected the histological picture and could have been interpreted as a malignant process if viewed in isolation. Review of the literature and the cases presented suggest that the CT appearances of vascular hamartomas can be diverse, and to avoid a misdiagnosis the radiological features should be considered in conjunction with the clinical and histopathological findings.

Retroperitoneal cystic lymphangioma section imaging in two cases, and review of the literature

Two patients with retroperitoneal cystic lymphangioma are reported with a review of the medical literature. In one, the patient was asymptomatic from the lesion but had a computed tomography (CT) and an ultrasound to evaluate the extent of disease with a known carcinoma of the colon. The second patient presented with an acute abdominal pain requiring surgical management. CT on this patient showed multiple cystlike cavities filled with fluid, in a retroperitoneal location. The preoperative diagnosis of retroperitoneal cystic lymphangioma was confirmed at surgery. Magnetic resonance (MR) performed on the second patient gave better delineation of craniocaudal extent and showed one of the cysts to have probable hemorrhage.

Intra-abdominal lymphangioma

The historical background, aetiology, clinical features, radiographic findings and treatment of abdominal lymphangiomas are reviewed. The condition may give rise to the acute surgical abdomen.

Urethral obstruction owing to retroperitoneal cystic lymphangioma

We report a case of cystic lymphangioma arising from retroperitoneal tissues of the pelvis, which caused urethral obstruction and eventual urinary retention. Sonography and computerized tomography demonstrated a retroperitoneal cystic mass in the pelvis. A preoperative diagnosis of retroperitoneal cystic lymphangioma was suggested by typical computerized and sonographic features.
