Neuromuscular choristoma (NMC) is a rare benign peripheral nerve lesion consisting of mature skeletal muscle fibers admixed with nerve fascicles. Aggressive fibromatosis frequently develops in association with NMC, often after surgery or biopsy, but the exact pathogenesis is not known. We present a case of NMC complicated by aggressive fibromatosis evaluated by F-FDG PET/CT and examine the relationship of metabolic activity and MRI signal characteristics.
神经肌肉嵴瘤（NMC）是一种罕见的良性周围神经病变，由成熟的骨骼肌纤维与神经束混合而成。侵袭性纤维瘤病常与 NMC 相关，常发生于手术后或活检后，但确切的发病机制尚不清楚。我们报告了一例 F-FDG PET/CT 评估的伴侵袭性纤维瘤病的 NMC 病例，并检查了代谢活性与 MRI 信号特征的关系。
