Two giant peritoneal loose bodies were found in the pelvis in a 79-year-old man. These bodies were demonstrated by computed tomography and magnetic resonance imaging to be well circumscribed masses and to have marked calcification in their central portion. Preoperatively, these bodies had been diagnosed as a calcified leiomyoma originating from the rectum; however, surgery revealed these lesions to be detached appendices epiploica. Histological examination showed that these peritoneal loose bodies consisted of thin layers of eosinophilic substance and had no cellular component. Small peritoneal loose bodies are occasionally found during laparotomy, but such large ones measuring 6 cm are very rare. In our case, accurate diagnosis could not be obtained preoperatively, because these loose bodies mimicked calcified leiomyoma of the rectum.
一名79岁男性盆腔内发现两个巨大的腹膜游离体。计算机断层扫描和磁共振成像显示，这些肿物边界清晰，中央部分有明显钙化。术前，这些肿物被诊断为起源于直肠的钙化平滑肌瘤；然而，手术发现这些病变为游离的网膜附件。组织学检查显示，这些腹膜游离体由嗜酸性物质薄层组成，无细胞成分。剖腹手术中偶尔会发现小的腹膜游离体，但如此大的（直径6厘米）非常罕见。在我们的病例中，术前未能获得准确诊断，因为这些游离体酷似直肠钙化平滑肌瘤。
