INTRODUCTION: The aim of the present study is to call the radiologist's attention to peritoneal cysts (PC) when making the diagnosis of cystic masses in patients with a history of long-standing abdominal surgery. MATERIAL AND METHODS: Four cases of histologically proven peritoneal cysts, discovered 2 to 21 years after abdominal surgery were studied with ultrasonography (US) and computed tomography (CT). The symptoms leading to the diagnosis of PC included abdominal pain, discomfort and palpable mass. RESULTS: On US and CT, the lesion of inflammatory origin appeared as a flaccid, septated and thin-walled cystic mass often mistaken for an ovarian lesion. Positive diagnosis of PC can be achieved at pathology examination by the identification of a mesothelial layer on the inner surface of the cyst. CONCLUSION: CT or US images showing a flaccid multiseptated thin-walled cystic mass in a patient who has a history of previous abdominal surgery should draw the radiologist's attention to the diagnosis of PC among other cystic tumors.
