Scintigraphic Findings in Plant Thorn Tenosynovitis of Finger

A 37-year-old women with pain and swelling in the third finger of the left hand for 10 months secondary to a plant thorn injury in her garden is presented. Three-phase bone scintigraphy was subsequently requested after the results of plain radiography were reported as normal. Dynamic bone scintigraphy showed increased activity in the proximal phalanx on the 3 phases of the study. Magnetic resonance imaging described the inflammatory soft tissue formation around the third flexor tendon as tenosynovitis. Culture of biopsy material was negative, and the histology was consistent with chronic inflammatory changes.
