Abstract
A 60-year-old woman with chronic pain in the left long finger, occasionally involving
the ring finger and intermittently extending to the hand, wrist, and distal forearm,
was referred for radiographs and a triple-phase technetium-99m methylene diphosphonate
bone scintigraphy to evaluate for possible complex regional pain syndrome. Initial
radiographs were normal. A three-phase bone scan revealed focal radiotracer uptake
at the distal aspect of the long finger during the blood pool phase only, with normal
blood flow and delayed phases, suggesting a hypervascular soft tissue tumor. Follow-up
magnetic resonance imaging showed a hypervascular nodule in the nail bed of the long
finger. The lesion was surgically resected, and pathology results confirmed the diagnosis
of a glomus tumor.
