Intraosseous Lipoma of Calcaneus, Rare Cause of Chronic Calcaneal Pain: A Case Report.

Intraosseous lipoma is a rare, benign primary tumor occurring in the bone. Herein, we reported a 45-year-old man with chronic right posterior heel pain. In this study, the man was treated conservatively due to plantar fasciitis. During a one-month follow-up visit, the patient had no symptoms of relief in the right heel pain. Initially, calcaneal X-ray was taken, which revealed an expansile unicameral lytic lesion with central calcification on the right calcaneus. Moreover, computed tomography scan revealed an expansile lytic lesion on the right calcaneus. The diagnosis was confirmed as calcaneal lipoma in magnetic resonance imaging. The patient underwent curettage and autogenous iliac crest corticocancellous bone graft under general anesthesia. In a 3-month postoperative follow-up, the patient returned to full ambulation. Postoperative radiographs demonstrated continued remodeling and healing of the graft site. The purpose of this article was to increase awareness among clinicians about the existence of this rare cause of calcaneal pain.
