Patient with Neurofibromatosis Typ

id rounded, deeply enhancing lesion was present in the su-perior cerebellar vermis (Fig 1A). This lesion was of high signal intensity on T2-weighted images (Fig 1B). Two small focal areas of high signal intensity in the globus pallidus bilaterally were also noted on T2-weighted se-quences. The remaining brain and optic pathways were normal. Single-volume (3 3 3 3 3 cm) proton MR spec-troscopy of the cerebellar lesion was done (Fig 1B and C). MR spectroscopy was done with PRESS (point-resolved occurs in approximately 10 % of patients with neurofibromatosis type 1 (2). Growth is ex-tremely unlikely after 10 years of age, and if it occurs it warrants careful follow-up to exclude tumor (2). Hamartomas of the basal ganglia can be larger than those elsewhere in the brain and occasionally are hyperintense on unen-hanced T1-weighted images (3). The presenc
