神经脂肪瘤病，也称为纤维脂肪瘤性错构瘤，是一种罕见的神经疾病，通常影响正中神经。MRI表现具有特征性。我们描述了两例涉及坐骨神经，一个非常不寻常的位置，这种病变的神经脂肪增多症，在坐骨神经病变的患者。这些病例与文献中描述的其他神经的典型特征相同，但也包含以前未强调的非典型特征，与脂肪沉积的分布和程度的变化有关。为了避免不必要的手术切除病变，识别该实体的MRI表现是很重要的。
Lipomatosis of nerve, also known as fibrolipomatous hamartoma, is a rare condition of nerve, usually affecting the median nerve. The MRI appearance is characteristic. We describe two cases of lipomatosis of nerve involving the sciatic nerve, an extremely unusual location for this lesion, in patients with sciatic neuropathy. These cases share the typical features previously described in the literature for other nerves, but also contain atypical features not previously highlighted, relating to the variability in distribution and extent of the fatty deposition. Recognition of the MRI appearance of this entity is important in order to avoid unnecessary attempts at surgical resection of this lesion.
