A large, well-encapsulated intraneural lipoma occurred within the sciatic nerve of a 34-year-old woman. In a review of the literature, significant differences were noted between the well-encapsulated and the diffusely infiltrative lipofibromatous hamartoma types of intraneural lipomas. The average age at the time of appearance of the well-encapsulated type is 45 years, with female predominance, while the infiltrative type arises in a younger age group (average age, eight years) with no sexual predominance. To avoid a recurrence, total excision is recommended in cases of the well-encapsulated type. Attempts to excise the diffusely infiltrative type are likely to fail.
一名34岁女性的坐骨神经内出现了一个大的、包膜完整的神经内脂肪瘤。在文献回顾中，发现包膜完整型和弥漫浸润型神经内脂肪瘤（即脂肪纤维瘤性错构瘤）之间存在显著差异。包膜完整型出现时的平均年龄为45岁，女性居多，而浸润型出现在较年轻的年龄组（平均年龄8岁），无性别优势。对于包膜完整型病例，为避免复发，建议进行完整切除。试图切除弥漫浸润型很可能会失败。
