MR imaging findings included diffuse linear dural thickening and enhancement (n=6); focal dural thickening and enhancement contiguous with orbital, nasal, or paranasal disease (n = 5); infarcts (n = 4); nonspecific white matter areas of hig h signal intensity on intermediate-weighted and T2-weighted images (n-10); enlarged pituitary gland with infundibular thickening and enhancement (n = 2); a discrete cerebellar lesion that was probably granulomatous in origin (n = 1); and cerebral (n = 8) and cerebellar atrophy (n = 2). MR imaging demonstrated the wide spectrum of findings of central nervous system involvement in patients with Wegener granulomatosis, and was particularly useful for the evaluation of direct intracranial spread from orbital , nasal, or paranasal disease. |
