A case of cystic mediastinal lymphangioma]

A 41-year-old man was admitted to our hospital because of an abnormal shadow which was pointed out on the chest x-ray film in mass screening. The operation was performed through left thoracotomy. The cyst was unilobular and 43 x 36 x 36 mm in size, located in the middle position of upper mediastinum. This localization has not been reported among 46 cases of the mediastinal lymphangiomas in Japan. Preoperative diagnosis is very difficult since roentogenographic feature is few for ruling out other mediastinal tumors. The complete resection of the cyst is recommended.     

A case of giant mediastinal cystic lymphangioma

A 13 year-old boy was admitted because of anterior chest pain, fever up and exertional dyspnea. Chest X-ray film showed a large mass shadow on the middle and lower lung field with positive silhouette sign. Under the ultra-sonic tomogram the mass showed cystic pattern with septum. The bloody fluid collected by puncture suggested hemorrhage into the cyst. Chest CT scan revealed a well defined cystic mass in the left thoracic space. The mass reached to the right thoracic space through behind the Inferior Vena Cava (IVC). At operation, although the tumor adjoined heart, esophagus, diaphragma and IVC, it was removed completely. Pathological diagnosis was cystic lymphangioma.     

Mesenteric cystic lymphangioma: A case report

Introduction and importanceMesenteric cystic lymphangiomas are rare benign lesions of the abdominal cavity characterized by lymphatic vessels malformation with an unknown etiology. Despite the silent clinical course of mesenteric cystic lymphangiomas, they are considered as clinically tricky lesions with an immense spectrum of presentations.Case presentationWe present a case of abdominal mesenteric cystic lymphangioma in a 1-year 9-month-old female patient, who complained of fever and abdominal pain for 10 days duration. Laboratory investigations, abdominal X-ray, ultrasonography, computed tomography and histopathological examination were all used to establish the diagnosis.Clinical discussionA trial of true-cut biopsies performed by an interventional radiologist was not informative, so a multidisciplinary team decision was made to excise the mass. Intraoperative findings include multiloculated fused cystic lesion (8.0 × 5.0 × 4.0 cm) on the descending mesocolon. Histopathological examination revealed the diagnosis of a mesenteric cystic lymphangioma. The postoperative period was not complicated.ConclusionMesenteric cystic lymphangiomas are mostly asymptomatic in nature, yet predisposed to life threating events. Surgical excision is the modality of treatment characterized by low recurrence rate and a non-complicated postoperative period.     

Adrenal cystic lymphangioma. A case report]

Adrenal cysts are uncommon. A case of left adrenal cystic lymphangioma in 16 year old boy is reported. The adrenal cyst was a chance finding during radiological investigation for abdominal pain. Ultrasound and CT scan showed the cyst and suggested the correct diagnosis of cystic lymphangioma of the left adrenal gland. The patient underwent surgery and a left adrenalectomy was performed. Histology confirmed the previous diagnosis of cystic lymphangioma.     

Giant cystic lymphangioma of right mesocolon: A case report

IntroductionCystic lymphangiomas are rare benign tumors of the lymph vessels and are usually found in children. However, abdominal cystic lymphangioma in mesocolon is extremely rare in adult patients.Presentation of caseWe reported a 15-year-old female with giant cystic lymphangioma of the right mesocolon. On examination, only abdominal pain was confirmed. Abdominal computed tomography (CT) showed a large multiseptated cystic mass. The patient underwent a total right mesocolic excision with the lesion. The patient recovered well on postoperative follow-up and was discharged on the fifth day. No evidence of recurrence had also been found in three months follow-up period.DiscussionThe diagnosis of intra-abdominal cystic lymphoma is often dismissed because the clinical symptoms are nonspecific. It is easy confusion because the ultrasound and CT scan images are relatively similar to the mesenteric and omental cysts. Sclerosing therapies may cause long-term consequences such as local recurrences with a very high proportion. Complete resection, including resection of the involved organs, is necessary. With tumors surrounding the colon, surgeons should consider performing removal block colon-lesion.ConclusionComplete tumor removal is the optimal choice for the management of intra-abdominal cystic lymphangioma. However, incomplete resection may lead to local recurrence.     

Abdominal cystic lymphangioma: a case report

Intra-abdominal cystic lymphangioma is a rare dysembryogenetic tumour. Although laparoscopic treatment may be feasible and has been reported in the literature, the extension of the mass to the retroperitoneum can make a minimally invasive surgical approach difficult or impossible. We describe the case of a patient with lymphangioma with retroperitoneal extension who underwent successful surgical therapy.     

Mediastinal cystic lymphangioma; report of a case

A cystic lymphangioma is a rare mediastinal benign tumor. A 38-year-old male was referred to our hospital because of an mediastinal mass incidentally detected on chest X-ray. The mass had enlarged rapidly during the course of 1 year. Computed tomography (CT) of the chest showed a 7 cm well defined cystic tumor in the left anterior mediastinum. Magnetic resonance imaging (MRI) demonstrated a mass with heterogeneous high signal intensity on enhanced T2-weighted images. The cystic tumor, localized in the mediastinal adipose tissue, was completely resected by a thoracoscopic procedure. A pathological examination confirmed the diagnosis of a cystic lymphangioma.     

A successful case of mediastinal cystic lymphangioma and statistical considerations in the Japanese literature

A 38-year-old man with large mediastinal cystic lymphangioma was successfully treated. Although he was asymptomatic, mass lesion on chest X-ray, pointed out two years ago, has rapidly increased in its size. The operation was performed through right thoracotomy and the cyst was unilobular and 10 X 8 X 8 cm in size, presented in the right upper anterior mediastinum. It contained about 250 ml of yellowish clear fluid with very thin wall, which was verified as tissue lymph by biochemical examination. Only 27 cases of mediastinal cystic lymphangiomas have been reported in the Japanese literature by 1988. Complete resection of the cyst should be recommended, since almost no evidence of postoperative recurrence would be expected.

Adrenal cystic lymphangioma: A case report and review of the literature

A 37-year-old female was being evaluated for fever when a huge cystic lesion of about 9 × 10.5 cm² in size in the right adrenal fossa with internal septal structures containing spots of calcification was found incidentally on computed tomography. A right adrenal cyst was suspected, and right adrenalectomy and surgical resection of the lesion were then performed. The pathology showed multilocular spaces lined by flat cells, compatible with adrenal cystic lymphangioma. Immunohistochemically, the tumor was strongly positive for D2-40 and CD31. She received regular imaging follow-up, and no metastatic disease has been found until now. The radiological and pathological features of adrenal cysts and the treatment strategy for adrenal lymphangiomas are discussed.     

A case of retroperitoneal cystic lymphangioma]

A case of retroperitoneal cystic lymphangioma in a 62-yr-old woman presented as symptom-free abdominal swelling. The intraoperative diagnosis was confirmed histologically. Radical management consisted of stripping of the cyst from its adjacent structures. The postoperative course was uneventful.     

A case of cystic lymphangioma of the liver

Here is a case report about a cystic lymphangioma of the liver, a rare benign tumor, extremely difficult to diagnose with certainty in spite of the wide range of examinations today available. Surgical intervention is still the most important means to achieve the final diagnosis. The authors also provide a discussion about the pathogenesis and the clinical manifestation of the disease.     

Voluminous cystic lymphangioma of the retroperioneum in an adult. A case report

Intra-abdominal cystic lymphangiomas are very rare tumours in adults. They are preferentially located in the neck, extremities and axillae in children. The authors report a case occurring in a 37-year-old female who had been experiencing dyspepsia and abdominal tension for a few weeks and was successfully treated surgically.     

Huge cystic lymphangioma of the pancreas: report of a case

We report herein the case of a 33-year-old woman who presented with palpable abdominal swelling found to be caused by a huge lymphangioma of the pancreas. An abdominal computed tomographic (CT) scan showed a large multilocular cystic mass with water-dense contents, which was derived from the pancreatic head. A pancreaticoduodenectomy (PD) was performed because the tumor had invaded the duodenum. The resected tumor, which was 23 × 12 × 23 cm in size with 2 l of serous fluid, was pathologically diagnosed as a cystic lymphangioma. The endothelial cells lining the internal surface of the cystic spaces were immunohistochemically positive for factor VIII-R antigen and CD31. Our review of the literature revealed 45 reports of lymphangioma of the pancreas, including this one, but to the best of our knowledge this is only the fifth case that required a PD. Nevertheless, we recommend that a complete resection be performed to reduce the risk of recurrence. Received: April 3, 2000 / Accepted: March 6, 2001
