Fluoro-deoxy glucose positron emission tomography-computed tomography in a case of natural killer/T-cell lymphoma with bilateral adrenal involvement

Natural killer/T-cell (NK/T-cell) lymphoma is a rare condition, which presents as necrotic, granulomatous lesions involving the nose and the upper respiratory tract. The condition usually has an aggressive clinical course. The predominant subtype of NK/T-cell lymphoma noted in Asian population is the nasal type. We describe a case of biopsy-proven NK/T-cell lymphoma with bilateral adrenal involvement. Adrenal involvement by lymphoma is usually of B-cell type and occurs in disseminated disease and often unilateral. Bilateral adrenal involvement by T-cell lymphoma is extremely rare.
