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.
