Diagnosis: Lhermitte-Duclos disease
CT may show a nonspecific hypo attenuating cerebellar mass; calcification is sometimes seen.
FDG-PET shows increased uptake.
Lhermitte-Duclos disease (LDD), also known as dysplastic cerebellar gangliocytoma, is a rare tumor of the cerebellum.
Lhermitte-Duclos disease typically presents in young adults.
Symptoms are typically related to raised intracranial pressure, obstructive hydrocephalus and, to a lesser degree, cerebellar dysfunction.
The dysplastic mass grows very slowly, and initial treatment revolves around treating hydrocephalus.
