Abstract
We present the case of a 77-year-old male with a history of prostate cancer. Follow up PET-CT and contrast-enhanced CT demonstrated a small peritoneal loose body or “mouse” in the pelvis. This is an uncommon, benign, asymptomatic finding which is usually incidentally discovered. The significance of being aware of this entity is to distinguish it from metastasis, especially in patients with known abdominal and pelvic malignancies.

Summary
Peritoneal loose bodies or “mice” are commonly small mobile lesions falling into the category of an incidentaloma. We present the case of a 77-year-old male with a history of prostate cancer. Follow up PETCT and contrast-enhanced CT demonstrated a small peritoneal loose body or “mouse” in the pelvis. CASE PRESENTATION A 77-year-old male with a remote history of prostate cancer was referred to our imaging facility after undergoing a prostatectomy at an outside facility. A contrast-enhanced CT abdomen and pelvis was performed which showed no acute findings to explain his symptoms.
