ABSTRACT

Diagnosis: Nonossifying fibroma

History: Patient developed acute pain in right knee while playing basketball, and radiographs were obtained.

Findings: Lateral radiograph of right leg shows a well-defined lytic lesion in the posterior cortex of the distal tibial diaphysis. The lesion has a bilobular appearance with a sclerotic border.

Ddx: *Fibrous cortical defect (defined as 0-2 cm and confined to cortex) *Nonossifying fibroma (lesion >2 cm OR not confined to cortex) *Osteoblastoma (suggested by ossification and calcification) *Adamantinoma (suggested by medullary invasion)

Dxhow: Characteristic appearance on serial radiographs

Exam: Physical exam provided no evidence of bony trauma or ligamentous instability.

No MeSH data available.
