ABSTRACT

Diagnosis: Avascular Necrosis of the Femoral Head

History: 52 y.o. man presents with trouble urinating. One year ago, previously presented to ED for left hip pain with radiographs demonstrating only DJD. Medications include only intermittent NSAID use for left hip pain. (DJD)

Findings: • Radiographic 4.3 x 3 cm area of geographic lytic lesion in the left proximal femoral head. • CT Geographic sclerotic and lytic lesion in the left femoral head. • Scintigraphic Rim of intense increased radiotracer uptake in the left femoral head with central photopenia (doughnut sign)

Ddx: • Avascular necrosis • Metastatic or primary neoplastic disease • Infection • Trauma

Dxhow: Imaging.

Exam: N/A

No MeSH data available.


Close up shows the abnormal increased radiotracer accumulation in the left femoral head.  There is a central region of photopenia  - the classic "doughnut sign" of avascular necrosis/ostenecrosis.
