Abstract

A 42-year-old woman suffered shortness of breath and whole-body pain, more prominent in both thighs. After the initial assessment, a paraneoplastic syndrome was considered clinically, and FDG PET/CT was performed to search culprit malignancy. The images did not reveal any focal lesion typical of solid hypermetabolic malignancy. Instead, diffuse increased muscle activity was noted in most musculatures, with some focally intense. The findings were suggestive of polymyositis, which was subsequently confirmed.

摘要

一位 42 岁女性出现呼吸急促和全身疼痛，双大腿更为明显。初步评估后，临床上考虑副肿瘤综合征，并进行了 FDG PET/CT 以寻找恶性肿瘤。图像未显示任何典型的实体高代谢恶性肿瘤的局灶性病变。相反，大多数肌肉中均可见弥漫性肌肉活动增加，有些部位呈局灶性增强。这些发现提示多发性肌炎，随后得到了证实。
