Abstract

PURPOSE:

To familiarize ophthalmologists with the management of a "solitary hot lesion" on bone scan as part of a metastatic examination.

METHODS:

Case report of a 27-year-old man with primary Ewing sarcoma of the fibula. Bone scan as part of a metastatic evaluation showed increased uptake in the left orbit. A metastatic lesion could not be ruled out radiologically.

RESULTS:

A biopsy was performed, and the lesion was found to be osteoid osteoma; therefore, the patient received only local radiation therapy to the fibula. Eight months later, the patient developed metastatic Ewing cell sarcoma of the sphenoid sinus and subsequently died.

CONCLUSIONS:

Because of the high sensitivity but low specificity of bone scan, secondary lesions on bone scan are not necessarily metastases. A biopsy specimen is often required for pathologic diagnosis.
