Abstract
In this case of biopsy-proved granulomatous angiitis, MR showed prominent leptomeningeal enhancement with comparatively little parenchymal involvement. Pathologically, granulomatous angiitis chiefly affects small vessels, with a predilection for those in the leptomeninges. Although marked leptomeningeal enhancement is not the most common finding, vasculitis should be added to the differential diagnosis of this MR appearance.
摘要
在这例经活检证实的肉芽肿性血管炎病例中，磁共振成像（MR）显示软脑膜显著强化，而脑实质受累相对较少。病理上，肉芽肿性血管炎主要累及小血管，尤其好发于软脑膜的血管。虽然明显的软脑膜强化并非最常见的表现，但在对这种MR表现进行鉴别诊断时应考虑血管炎。
