Lymphangioma is a rare, benign mesenchymal neoplasm, which is characterized by numerous intercommunicating cystic spaces containing lymphatic fluid. It is considered a congenital disease resulting from the obstruction of regional lymph drainage during the developmental period. Lymphangioma frequently occurs in the cervical neck and axilla, also in the retroperitoneum, mediastinum, mesentery, omentum, colon, and pelvis, rarely in the perirenal space. These tumors usually present in childhood, but infrequently, these also present in adults...

Duplications of the gastric tract are made up of a wide variety of masses throughout the gastrointestinal tract. They may have tubular or cystic morphology. Some duplications are associated with malformations, especially those located in the thorax, which can be associated with intestinal atresia, and malformations of the urinary tract or vetebras (Lund. 2012).

Retroperitoneal cysts are not common. Primary retroperitoneal cysts are essentially benign in nature. Mostly, they are detected incidentally. At times, they may attain a huge size and may present with large abdominal lump. In our case, a 55-year-old man had a left-sided large idiopathic retroperitoneal cyst, for which complete curative excision was performed.

RATIONALE: Retroperitoneal bronchogenic cysts without specific clinical manifestations are extremely rare and difficult to diagnose preoperatively and are easily misdiagnosed as left adrenal or pancreatic tumors. PATIENT CONCERNS: A 48-year-old woman with the chief complaint of obscure epigastric pain for 1 month and with no other gastrointestinal symptoms and no significant medical history. The patient had signed informed consent for publication of this case report...

This is a rare case of a prostatic ductal adenocarcinoma. A 75-year-old gentleman presented with complaints of lower urinary tract symptoms, constipation, and occasional hematuria. The clinical and radiological differentiations from other retroperitoneal soft cystic lesion were difficult, and fine needle aspiration cytology from the papillary solid components of the cyst was required to reach diagnosis. Transrectal ultrasound-guided biopsy was performed in view of the raised serum prostate-specific antigen (>100 ng/mL); however, the cyst was ruptured without yielding any tissue for biopsy...

Tuberous sclerosis is a rare genetic disease with multiple organ involvement. Renal involvement is manifested by the presence of angiomyolipomas and cysts. Angiomyolipomas due to the progressive increase in size over time can complicate by bleeding that can lead to severe retroperitoneal hemorrhages. Hence, it is important to perform an active surveillance of the masses and to institute therapeutic attempts in order to manage or prevent any complication. We present three clinical cases of three women with various clinical presentations and treated in different ways...

A 40-year-old man complaining of abdominal distention was referred to our hospital. Computed tomography of the abdomen demonstrated a very large abdominal mass with fat and calcification. The size of the mass rapidly increased from 30cm to 40cm over two weeks. The tumor was removed and diagnosed by pathological examination to be a retroperitoneal mature cystic teratoma that contained a 40-cm long, mature intestinal tract-like cyst, together with bone marrow and fat. The rapid growth of the tumor may have been caused by an increased secretion in the cyst...

Testicular seminoma is the most common malignant tumor of the testis. It classically manifests as a painless mass. Radiologic evaluation with high-frequency ultrasonography (US) is critical for diagnosis. Seminomas are usually homogeneously hypoechoic masses at US. In challenging cases, magnetic resonance (MR) imaging may help confirm that a mass is intratesticular and provide data for local staging. Computed tomography (CT) provides valuable information for staging, including the presence and size of retroperitoneal lymph nodes...

Namrata Krishnan, Mark A Perazella
Patients with underlying kidney disease are often required to undergo imaging for a variety of purposes including diagnosis and prognosis. A test that is being increasingly used with for this group of patients is the positron emission test (PET) scan. In addition, combining the nuclear medicine technique (PET) with computed tomography scan allows additional imaging advantages over either alone. These imaging modalities are commonly used for a number of extrarenal indications (ie, cancer, coronary artery disease, central nervous system disease, infectious diseases, and others)...

Background: Enteric duplication cysts are congenital malformations that typically affect children in infancy, but can also affect adults. Rarely, these cysts can be complicated by malignancy. We present the first case of retroperitoneal duplication cyst that was complicated by malignancy transformation and managed by robot-assisted excision. Case presentation: A 64-year-old female with a history of a left-sided renal cyst presented with a 4-month history of abdominal pain and fatigue. MRI revealed a bilobed cyst, with components measuring 6...

Echinococcus granulosus causes a zoonotic infection called cystic echinococcosis (CE) or more commonly known as hydatid disease. Although the two most common locations of hydatid cyst are liver and lung, it may also appear in other parts of the body. Clinical presentation of the hydatid disease depends on the site and size of the lesion. A retrospective study was done in Medical College and Hospital, Kolkata, from January 2012 to June 2014, to find the site of involvement, distribution, clinical features, history of contact, mode of presentation, laboratory diagnosis, and treatment modalities of the cases of hydatid cyst...

A 78-year-old woman presented to the urology clinic with a large, symptomatic left-sided abdominal cyst that was believed to be renal in etiology for many years and that had been percutaneously drained 3 times previously with persistent regrowth. The patient underwent laparoscopic resection of this mass, which proved to be a completely distinct retroperitoneal cystic structure and was not renal in nature. Pathologic analysis ultimately revealed a rare occurrence: a benign retroperitoneal Müllerian serous cystadenoma...

Prominent cyst formation is an unusual feature of liposarcoma. We report here a case of dedifferentiated liposarcoma with huge cystic change without preoperative chemo- or radiation therapy. The lesion arose in the retroperitoneum juxtaposed to the right kidney of a 67-year-old woman. She underwent a surgical removal of the retroperitoneal cyst. The cystic tumor contained 1600 mL of old bloody fluid, and its wall was composed of edematous, inflamed or sclerosing fibrous tissue with fatty tissue containing abundant atypical stromal cells, which were immunohistochemically positive for MDM2 and CDK4, and demonstrated MDM2 gene amplification by fluorescence in situ hybridization...

Cystic trophoblastic tumor (CTT) has been described in postchemotherapy retroperitoneal lymph node dissections of patients with testicular germ cell tumors. Prognostically, this lesion is similar to teratoma and no further treatment is required after surgery in the absence of other components. CTT has not, however, been reported in the testis. We identified 14 CTTs in the treated (4) and untreated (9; no information for 1 patient) testes of patients 15 to 43 years old (median, 25) with mixed germ cell tumors...

A 69-year-old woman with a 10-year medical history of recurrent retroperitoneal dedifferentiated liposarcoma presented with a 3-cm large hemorrhagic and multicystic left-sided retroperitoneal mass. Histopathological examination of the resected specimen showed a heterogeneous, high-grade mesenchymal nonlipogenic tumor with areas of osteoblastic/osteosarcomatous differentiation and aneurysmal bone cyst-like features. Based on the clinical presentation, the morphology, and the supportive immunohistochemical and molecular findings (MDM2 overexpression and amplification of the MDM2 gene, respectively), a diagnosis of a dedifferentiated liposarcoma with heterologous osteosarcomatous differentiation and an aneurysmal bone cyst-like morphology was made...

INTRODUCTION: Retrorectal cysts are rare benign lesions which are frequently diagnosed in middle-aged females. According to their origin and histopathologic features, retrorectal cysts are classified as squamous-lined (dermoid or epidermoid) cysts, postanal gut (tailgut) cysts, and rectal duplications (enteric or enterogenous cysts, enterocystomas). Described in this case report is an extremely unusual patient, a woman who simultaneously had a retrorectal cyst and an ovarian serous cystadenoma in addition to a long history of misdiagnosis and multiple unsuccessful surgeries...

Pseudocysts account for approximately 70% of all cystic lesions of the pancreas. One of the most dangerous complications of pancreatic pseudocysts is bleeding into the cystic lumen; the most common cause of the bleeding is a splenic artery pseudoaneurysm rupture. This paper presents the case of a 37-year-old man treated surgically for a massive intra-abdominal haemorrhage caused by a splenic artery pseudoaneurysm rupture into the lumen of a tail of pancreas pseudocyst with its subsequent perforation into the abdominal cavity and retroperitoneal space...

Background Lymphangioleiomyomatosis (LAM) is a rare disease involving the bronchi, lymphatic vessels, and veins. However, there are few reports about lymphatic vessel abnormalities associated with LAM. Purpose To evaluate computed tomography (CT) lymphangiography findings in cases of LAM, especially lymphatic vessel abnormalities. Material and Methods Twenty-seven patients with LAM underwent direct lymphangiography (DLG), followed by a post-procedural thoracoabdominal CT examination. Results All 27 patients were diagnosed with LAM, including 25 (93%) with chylothorax, eight (30%) with chyloperitoneum, seven (26%) with chylous fluid in the chest and abdomen, and one (4%) with lower-limb lymphedema...
