SOLITARY MUSCULAR SARCOIDOSIS - CT, MRI, AND SCINTIGRAPHIC CHARACTERISTICS

Scintigraphy using gallium-67 (Ga-67) citrate and penvaralent technetium-99m dimercaptosuccinic acid {[Tc-99m(V)]DMSA} and other radiological examinations were performed in three patients with solitary mus cular sarcoidosis who had tumor-like muscular lesions. Although distinction from other invasive soft tissue tumors was difficult using plain and enhanced computed tomography and magnetic resonance imaging, marked uptake of Ga-67 and moderate uptake of [Tc-99m(V)]DMSA were shown at the sites of granulomatous inflammatory lesions of sarcoidosis. Both Ga-67 and [Tc-99m(V)]DMSA scintigraphy could be of value in the diagnosis and detection of distribution of granulomas of sarcoidosis in the soft tissue and in determining the appropriate region for biopsy.
