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.
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.
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.
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.
本研究的目的是在对有长期腹部手术史的患者进行囊性肿块诊断时，引起放射科医生对腹膜囊肿（PC）的关注。
对4例经组织学证实的腹膜囊肿进行研究，这些囊肿在腹部手术后2至21年被发现，采用超声（US）和计算机断层扫描（CT）进行检查。导致PC诊断的症状包括腹痛、不适和可触及的肿块。
在超声和CT上，炎症起源的病变表现为一个松弛的、有分隔的薄壁囊性肿块，常被误诊为卵巢病变。通过在囊肿内表面识别间皮层，病理检查可实现PC的阳性诊断。
对于有腹部手术史的患者，CT或超声图像显示为松弛的多分隔薄壁囊性肿块时，放射科医生应在其他囊性肿瘤中注意PC的诊断。
