Costochondral involvement in systemic candidiasis in heroin addicts: clinical, scintigraphic, and histologic features in 26 patients.
We studied the clinical, scintigraphic, and histopathologic characteristics of 26 intravenous drug abusers with costochondral involvement secondary to systemic infection with Candida albicans. The clinical findings were of a mass appearing in the anterior region of the thorax. In general, signs of inflammation were absent. Histopathologic study of this costochondral mass in 12 patients showed perichondritis in 100% and myositis in 87%, with secondary involvement of cartilage in 43% and of bone in 75%. Results of bone scintigrams using 99mTc-methylene diphosphonate were positive in only 7 of 15 patients (47%), with a correlation between positive uptake and osteitis. Gallium scintigraphy findings were positive in 9 of 10 patients (90%). The greater sensitivity of 67Ga was probably because the invariably present pericartilaginous inflammatory mass was not always accompanied by secondary cartilage and bone involvement.
