Abstract

Subcutaneous nodules and masses as the primary manifestation of diffuse large B-cell lymphoma are exceedingly rare. We present 18 F-FDG PET/CT findings of multiple hypermetabolic nodules and masses distributed throughout the body, creating a characteristic "leopard man" appearance on the MIP image, in a 65-year-old man. An excisional biopsy of the right thigh mass confirmed the diagnosis of diffuse large B-cell lymphoma.

摘要

以皮下结节和肿块为主要表现的弥漫性大B细胞淋巴瘤极为罕见。我们报告了一名65岁男性患者的18F-FDG PET/CT检查结果，其全身分布有多个高代谢结节和肿块，在最大密度投影（MIP）图像上呈现出特征性的“豹人”外观。对右大腿肿块进行切除活检，确诊为弥漫性大B细胞淋巴瘤。
