67Gallium scanning in talc-induced pulmonary granulomatosis

DG Brown, A Aguirre and A Weaver

We describe a case of pulmonary granulomatosis in a user who habitually injected methylphenidate (Ritalin) intravenously; symptomatic and objective improvement occurred with corticosteroid therapy. A scan of the lungs using radioactive 67gallium showed an increased concentration of 67gallium throughout both lungs. There was a reduction in abnormal accumulation of 67gallium, improvement in the arterial oxygen pressure and the diffusing capacity for carbon monoxide, and a reduction in the infiltrate on the chest x-ray film two months after the institution of therapy. Before treatment the patient's symptoms and arterial deoxygenation increased despite the cessation of her drug abuse, thus raising the question of a self-perpetuating inflammatory process in a case of pulmonary deposition of talc.
