Cerebral hamartomas in neurofibromatosis type I

Case contributed by Dr Roberto Schubert

Presentation:

Known NF1 with typical stigmata. Blurred vision and headaches.

Patient Data:

Age: 8
Gender: Male
Race: Caucasian

Multple T2 moderately hyperintense lesions in the basal ganglia, the thalamus and hypothalamus, the brainstem and the dentate nuclei of the cerebellum. No signal alteration on DWI, no enhancement.

Case Discussion:

Those lesions are hamartomas that had already been seen on an MRI performed on that patient at the age of 5. They belong to the typical central nervous system manifestation of type I neurofibromatosis.
