Peritoneal loose bodies or “peritoneal mice” are rare well circumscribed benign masses composed of free-floating organized fat necrosis.

They are usually asymptomatic and found as “incidentalomas” during Imaging. Their pathogenesis is not well known. We report a rare case of giant intraperitoneal mice which was clinically misdiagnosed as left seminal vesicle malignancy. A review of the literature is also presented.展开更多

This disorder affects a wide age range from adults to childhood with no sex dominance. Malignant transformation is rare to date, and there are approximately 34 cases in literature about the transformation of synovial chondromatosis to chondrosarcoma. Case: We present case of a 27-year-old patient who had synovial chondromatosis in his elbow. Discussion: Radiographic findings are usually pathognomonic for the diagnosis. Multiple calcified loose bodies can be seen in the joint in radiographs. Computed tomography (CT) optimally depicts the calcified intraarticular fragments and extrinsic bone erosion. However, because the radioopacity cannot be detected in 1/3 of the cases, diagnosis becomes difficult. Treatment modalities include arthroscopic or open extraction of the loose bodies and arthropasty in the presence of severe osteoarthritis. Conclusion: Synovial chondromatosis should be kept in the differential dignosis of the chronic monoarticular pain and painful limitations of the range of motions of the joints.展开更多
