Meningioangiomatosis (MA) is a rare hamartomatous lesion of the cerebral cortex; to date only 18 cases with imaging findings have been reported in the English literature. The origin of MA is probably malformative, with possible association with neurofibromatosis. These lesions frequently cause seizures in young patients. We report two new cases seen at our institution and present their CT and MR findings clearly illustrating MA cortex infiltration. Gd-DTPA used in one of the two cases failed to cause enhancement.
脑膜血管外皮细胞瘤（MA）是一种罕见的大脑皮质错构瘤性病变；迄今为止，英文文献中仅报道了18例有影像学表现的病例。MA的起源可能是发育畸形，可能与神经纤维瘤病有关。这些病变在年轻患者中常引起癫痫发作。我们报告了在我们机构见到的两例新病例，并展示了它们的CT和MR表现，清晰地显示了MA对皮质的浸润。两例中的一例使用钆喷酸葡胺后未出现强化。
