Extraskeletal accumulation of Tc-99m HMDP in a tuberculous cold abscess

Abstract

A large and well-delineated area of increased uptake of Tc-99m HMDP in extraskeletal tissue is presented. This well-delineated scintigraphic lesion includes an extremely avid upper portion conforming to the right gluteal region, lateral to the iliac bone. The lower portion of the lesion spreads down to the lower two-thirds of the right femur as a lower, but still higher uptake compared to skeletal tissue. The final diagnosis of this lesion was a tuberculous cold abscess that was drained, and the therapy with a combination of three drugs was started.
