Note.—CECT indicates enhancement on contrast-enhanced CT images; HDCT, high attenuation (increased relative to gray matter) on nonenhanced CT images; T1E, enhancement on contrast-enhanced T1-weighted MR images, ↑T1, increased signal intensity on T1-weighted MR images; T2FE, enhancement on T2 FLAIR sequence; ↑T2, increased signal intensity on T2-weighted MR images; and ↓T2GE, decreased signal on gradient-echo T2-weighted images.
* Other findings included phthisis bulbi.
† Other findings included T1E in the midbrain, superior cerebellar peduncle, temporal lobe and ↑T2 in the thalamus, midbrain, pons, and cerebellum.
‡ Other findings included T1E in the midbrain and temporal lobe.
§ Other findings included T1E in the meninges, cerebellum, midbrain, Meckel cave and ↑T2 and T2FE in the meninges, cerebellum, midbrain, and Meckel cave.
