Xanthogranulomatous Osteomyelitis Presenting as a Subacute Infectious Condition in the Fibula of a Young Female

Xanthogranulomatous osteomyelitis is a rare, chronic inflammatory disease characterized by infiltrating lipidized histiocytes, lymphocytes, and plasma cells. Xanthogranulomatous osteomyelitis commonly presents as a mass-like lesion on imaging and may be mistaken for a tumor. Here, we describe an unusual manifestation of xanthogranulomatous osteomyelitis with imaging findings resembling those of Brodie's abscess, posing a diagnostic challenge in a child. Additionally, we suggest a potential correlation between xanthogranulomatous osteomyelitis and a history of prior trauma.
