Primary malignant lymphoma of the prostate is exceedingly rare. Here we report a case of a 65-year-old man who presented with increased urinary frequency, urinary urgency, and urinary incontinence for two years. Benign prostatic hypertrophy was suspected at primary impression. Ultrasound revealed a hypoechoic lesion of the prostate. The total serum prostate-specific antigen was within normal range. Positron emission tomography/computerized tomography (PET/CT) showed a hypermetabolic prostatic lesion. Prostate biopsy was consistent with a non-germinal center diffuse large B cell lymphoma. There was complete remission of the prostatic lesion following six cycles of chemotherapy as shown on the second PET/CT imaging. ¹⁸F-fluoro-deoxy glucose PET/CT is not only a complement to conventional imaging, but also plays a significant role in the diagnosis and evaluation of treatment response of prostatic lymphoma.
前列腺原发性恶性淋巴瘤极为罕见。我们在此报告 1 例 65 岁男性患者，其主要表现为尿频、尿急和尿失禁 2 年。初步印象为良性前列腺增生。超声显示前列腺低回声病变。总前列腺特异性抗原在正常范围内。正电子发射断层扫描/计算机断层扫描（PET/CT）显示前列腺高代谢病变。前列腺活检与非生发中心弥漫性大 B 细胞淋巴瘤一致。在第二次 PET/CT 成像上，六周期化疗后前列腺病变完全缓解。¹⁸F-氟脱氧葡萄糖 PET/CT 不仅是常规成像的补充，而且在前列腺淋巴瘤的诊断和治疗反应评估中也具有重要作用。
