Abstract:
Neurofibromatosis type 1 (NF1) is an autosomal dominant disorder that causes CNS tumors in around 20% of patients, being pilocytic astrocytomas (PA), and particularly optic pathway gliomas (OPG), the most common. We present three cases of NF1 patients referred for F-fluorocholine PET/CT because of suspected glioma in the setting of ongoing FUMEGA (Functional and Metabolic Glioma Analysis) trial. One case turned out to be a WHO grade I ganglioglioma; the second was a high grade glioma; and the last one (negative in PET) a probable low-grade glioma.
