A 85-year-old woman presented with macroscopic hematuria and miction pain. Cystoscopy revealed a wide-based submucosal mass, and biopsied specimens of the mass showed a B-cell lymphoma of the MALT type. Computed tomography (CT) showed a 7.5 X 3.0 cm solitary mass lesion situated from the anterior wall to the right lateral bladder wall, and magnetic resonance imaging (MRI) showed a low intensity in T1W1, high in T2W1 without invasion. After she was admitted to our hospital, TUR of the lesion was performed. The findings were consistent with extranodal marginal zone B-cell lymphoma of the MALT type. No evidence of lymphoma was found on the CT of the pelvis, chest X-ray and Gallium scintigraphy.The patient had stages I-AE lymphoma. The patient was treated with radiation therapy to the bladder and pelvis (40 Gy in 20 fractions) and was followed with CT every 3 months. She had no evidence of recurrnce.
