We report a case of giant peritoneal loose body with situs inversus totalis, together with a review of the literature.
A 75-year-old man with known situs inversus totalis complainted of pollakiuria during hospitalization for treatment of hepatocellular carcinoma in the liver segment S5 with the radio-frequency ablation method. A retroperitoneal tumor compressing the urinary bladder was diagnosed after close exploration, and an operation to remove the tumor was performed. The pathological examination revealed peritoneal loose body. He progressed satisfactorily and was discharged from the hospital 10 days after the operation. There have been no cases of peritoneal loose body with situs inversus totalis like our case in Japan as far as we could review.
