Aneurysmal Bone Cyst-cloaked Codman’s Tumor in the Patella: Case Report of an Easily Misdiagnosed Entity

CB with secondary ABC represents a diagnostic challenge due to atypical imaging features that mimic primary ABC. One must maintain high suspicion for this entity when evaluating lytic patellar lesions. Adequate tissue sampling and histopathological examination are mandatory for accurate diagnosis, as radiological findings alone are insufficient. Appropriate surgical management with intralesional curettage and bone grafting results in excellent functional recovery and low recurrence rates.
