This report describes a giant peritoneal loose body in the pelvic cavity. A 63-year-old man who was asymptomatic underwent a routine medical examination, which revealed a tumor in the pelvic space. Computed tomography and magnetic resonance imaging showed a smooth-surfaced mass with two marked calcifications in the central position. Preoperatively, we suspected a calcified leiomyoma originating from the wall of the sigmoid colon; however, at laparoscopic surgery we extracted a hard, egg-shaped mass 5 cm in diameter, with detached appendices epiploicae. Histological examination revealed that this peritoneal loose body was made up of thick layers of fibrous tissue with a few cellular components, and necrotic fat tissue in the central position. Small peritoneal loose bodies are occasionally found during laparotomy or autopsy, but such a large one is very unusual.
本报告描述了盆腔内一个巨大的腹膜游离体。一名63岁无症状男性接受常规体检时，发现盆腔有一个肿物。计算机断层扫描和磁共振成像显示一个表面光滑的肿块，中央有两处明显钙化。术前，我们怀疑是起源于乙状结肠壁的钙化平滑肌瘤；然而，在腹腔镜手术中，我们取出了一个直径5厘米的坚硬、椭圆形肿物，带有游离的网膜附件。组织学检查显示，这个腹膜游离体由厚层纤维组织和少量细胞成分组成，中央为坏死脂肪组织。小的腹膜游离体偶尔在剖腹手术或尸检中发现，但如此大的一个非常罕见。
