“…The retroperitoneal region is a rare localization of cystic lymphangiomas, however, it should be included in the differential diagnosis of cystic lesions (Tables I-III) (18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33). The recommended treatment for retroperitoneal cystic masses is complete surgical excision, as a partial resection is associated with increased rates of recurrence.…”

Abstract. Cystic lymphangioma is a type of benign tumor originating from the lymph vessels. The tumor commonly occurs in childhood, in the head or neck regions, and retroperitoneal localization and presentations in adulthood are rare. Determining a pre-operative diagnosis is often challenging, and in the majority of cases, a diagnosis is only possible subsequent to the histological examination of the surgical specimen. A radical resection is the recommended treatment for cystic lymphangioma, and recurrence is usually due to an incomplete excision of the mass. The present study reports 2 cases of cystic lymphangioma, localized in the pancreatic gland and duodenal wall respectively, which were treated with surgical resection. The study also briefly reviews the literature regarding the differential diagnosis of retroperitoneal cystic masses.

“…Although pseudomyxomas usually arise in the peritoneal cavity, they may occur in the retroperitoneum (24,25). Pseudomyxoma retroperitonei is caused by the rupture of a mucinous lesion in the retrocecal appendix and fixation of the lesion to the posterior abdominal wall (24).…”

Cystic lesions of the retroperitoneum can be classified as either neoplastic or nonneoplastic. Neoplastic lesions include cystic lymphangioma, mucinous cystadenoma, cystic teratoma, cystic mesothelioma, müllerian cyst, epidermoid cyst, tailgut cyst, bronchogenic cyst, cystic change in solid neoplasms, pseudomyxoma retroperitonei, and perianal mucinous carcinoma. Nonneoplastic lesions include pancreatic pseudocyst, nonpancreatic pseudocyst, lymphocele, urinoma, and hematoma. Because the clinical implications of and therapeutic strategies for retroperitoneal cystic masses vary depending on the cause, the ability to noninvasively differentiate between masses is important. Although there is substantial overlap of computed tomographic (CT) findings in various retroperitoneal cysts, some CT features, along with clinical characteristics, may suggest a specific diagnosis. CT may provide important information regarding lesion location, size, and shape; the presence and thickness of a wall; the presence of septa, calcifications, or fat; and involvement of adjacent structures. The most important clinical parameters include patient gender, age, symptoms, and clinical history. Familiarity with the CT and clinical features of various retroperitoneal cystic masses facilitates accurate diagnosis and treatment.

Pseudo myxomaperitonnei (PMP) is a rare case with progressive dissemination of mucinous tumours and mucinous ascites in the abdomen and pelvis with an estimated incidence of 1 to 2 out of a million. Psedomyxomaperitonnei is a neoplastic disease originating from a primary mucinous tumor of appendix, mucinous cystadenoma of ovary with a distinctive pattern of the peritoneal spread. Computed tomography and histopathology are the most reliable diagnostic modalities. We present a case of pseudomyxomaperitonnei in a 55 year old male presented with pain abdomen and abdominal distension with ascites. Ultrasonography localized collection noted in right iliac fossa and left iliac fossa and ascites present. Computed tomography showed localized collection noted in right iliac fossa and left iliac fossa which is arising from appendix and ascites present. Exploratory laparotomy peritoneal cavity filled with mucinous substance along with ruptured cyst wall in right iliac fossa was found. The mucinous substance drained and the ruptured cyst was resected with appendix at base. In conclusion, pseudomyxomaperitonnei is a rare presentation. Despite the current standard of treatment modalities as extensive surgical resection combined with chemotherapy, PMP frequently recurs with treatment options being limited at recurrence and with severe impact on quality of life.

Pseudomyxoma retroperitonei

Abstract: We report a rare case of pseudomyxoma retroperitonei in a 58-year-old woman with a past history of severe appendicitis. The imaging showed a multicystic mass similar to pseudomyxoma peritonei, but the tumor was located in the retroperitoneal space.
