Abstract

18F-Fluorodeoxyglucose (FDG) PET-CT is an excellent imaging modality for the evaluation of Non-Hodgkin lymphoma. We report a case of 65-year-old man with haematuria; rectal examination and ultrasonography revealed prostate mass. Staging 18F-FDG PET-CT images showed a large hypermetabolic, infiltrative prostate mass. Subsequent contrast enhanced CT images showed ill-defined heterogeneously enhancing fungiform mass with irregular outline involving the prostate, base of urinary bladder as well as the seminal vesicles. Biopsy showed diffuse large B cell lymphoma. 18F-FDG PET-CT is helpful in evaluation of disease extent and therapy response.

摘要

18F-氟代脱氧葡萄糖（FDG）PET-CT 是评估非霍奇金淋巴瘤的一种极好的影像学方法。我们报告了一例 65 岁男性血尿患者；直肠检查和超声检查显示前列腺肿块。分期 18F-FDG PET-CT 图像显示前列腺内有一个大的高代谢、浸润性肿块。随后的增强 CT 图像显示形状不规则的模糊不均匀强化的蘑菇状肿块，累及前列腺、膀胱底部以及精囊。活检显示弥漫性大 B 细胞淋巴瘤。18F-FDG PET-CT 有助于评估疾病程度和治疗反应。
