  		Fig 1. Sagittal T1-weighted spin-echo (TR/TE, 400/9.1 ms) (A) and coronal T2-weighted TSE (TR/TE, 3500/100 ms) images show lipomatous coloboma of the left eye (B). On the sagittal T1-weighted spin-echo (TR/TE, 400/9.1 ms) image of the medial brain, a cerebellopontine angle cistern lipoma is seen (C).

  		Fig 2. A, Left cerebral hemiatrophy with cortical developmental malformation is seen on the transverse T2-weighted TSE (TR/TE, 3500/100 ms) image. Thin caliber of the left ICA is also observed.

B, T2-weighted TSE (TR/TE, 3500/100 ms) transverse image from a higher section shows the collaterals in the basal cisterns.

C, Coronal T2-weighted TSE (TR/TE; 3500/100 ms) image shows atrophy of the left cerebral hemisphere with dilated lateral ventricles and temporal cortical dysplasia. Also, subcutaneous fat is diffusely thicker over the left frontotemporoparietal cranium.

  		Fig 3. Time-of-flight MR angiogram (TR/TE; 39/3.26) shows thin-caliber left ICA in all intracranial segments, with a tapering end and occlusion of the artery at its bifurcation.
