Peritoneal loose bodies, also referred to as peritoneal mice, are formed by torsion of epiploic appendages detaching from the large bowel, subsequently becoming loose within the peritoneal cavity. While often discovered incidentally during laparotomy or autopsy, emerging reports suggest they can manifest with diverse symptoms. Here, we present a 61-year-old patient experiencing lower abdominal pain and irritative voiding symptoms, ultimately diagnosed with a giant peritoneal loose body measuring 6.5 cm. Computed tomography (CT) imaging showed a well-circumscribed soft-tissue density mass with central calcifications, which was later confirmed during surgery. Only a few cases have been reported on giant peritoneal loose bodies. We also highlight characteristic features of imaging to establish the correct diagnosis.
腹膜游离体，也被称为腹膜鼠，是由从大肠分离的网膜附件扭转形成的，随后在腹腔内游离。虽然它们常在剖腹手术或尸检时偶然发现，但新出现的报告表明它们可能表现出多种症状。在此，我们报告一名61岁的患者，其出现下腹部疼痛和刺激性排尿症状，最终被诊断为一个直径6.5厘米的巨大腹膜游离体。计算机断层扫描（CT）成像显示一个边界清晰的软组织密度肿块，伴有中央钙化，这在后来的手术中得到了证实。关于巨大腹膜游离体的报道仅有少数几例。我们还强调了影像学的特征以确立正确的诊断。
