Abstract

This report describes an intra-abdominal mass caused by progesterone-containing controlled internal drug release (CIDR) devices in the abdominal cavity of a 28-month-old Japanese Black heifer presenting with infertility. Rectal examination revealed a mass containing a cartilage-like object in the pelvic cavity. Computed tomography revealed a mass containing two T-shaped foreign bodies. Laparotomy was performed to remove the mass containing the foreign bodies. The heifer was healthy at discharge seven days post-surgery. This case adds CIDR device as a new etiology for intra-abdominal masses. Furthermore, it highlights the usefulness of CT in diagnosing deep abdominal lesions.
