A Case of Mesenteric Pseudocyst Causing a Massive Abdominal Swelling
KeywordsMesenteric pseudocyst, peritoneal fluid, abdominal cyst
We present the case of a 55-year-old man, with a self-limited febrile condition associated to polyserositis with inconclusive investigation. Bilateral pleural and pericardial effusions resolved. The peritoneal fluid loculated and was compatible with an exudate. The patient remained clinically asymptomatic. Two years later, examination revealed a palpable and painless abdominal mass, which imaging study suggested a cystic lesion. Surgical resection was performed and the histological examination revealed a mesenteric pseudocyst.
Mesenteric pseudocysts are rare intra-abdominal cystic masses, mostly benign, without causing specific symptoms. Although imaging tests are useful for their differential diagnosis, the histology is mandatory.
