Abstract
CASE DESCRIPTION: A 1-year-old neutered male cat was examined because of a 6-month history of recurrent swelling and draining wounds affecting the craniomedial aspect of the distal portion of the left forelimb. CLINICAL FINDINGS: No lameness or neurologic deficits were evident. Examination of craniocaudal and lateromedial radiographic views revealed nonprogressive circumferential osteolysis and a mildly radiopaque, ring-shaped foreign body surrounding the radius and ulna. TREATMENT AND OUTCOME: During surgery, a tight elastic band surrounded by a thick fibrous tissue capsule was found encircling the limb. Microbial culture yielded a Staphylococcus sp that was susceptible to clindamycin. Follow-up monitoring via telephone communication with the owners 1.5 years after removal of the foreign body indicated that the cat had healed with no recurrence of drainage. CLINICAL RELEVANCE: Pressure osteolysis of the bones of the forelimb can be caused by a circumferential foreign body without associated neurologic abnormalities or lameness.
