The Teaching Point

Dysplastic gangliocytoma of the cerebellum, also known as Lhermitte-Duclos disease, is an uncommon hamartomatous tumor associated with Cowden syndrome that typically grows unilaterally in one of the cerebellar hemispheres. On MRI, Lhermitte-Duclos is characterized as a nonenhancing cerebellar mass with a distinct, striated appearance.

Abstract
The following case report features a middle-aged female patient, previously diagnosed with Cowden syndrome, who presented to the hospital with symptoms of headaches and changes in vision that began with no apparent cause and persisted for almost a month. MRI of the head confirmed a diagnosis of dysplastic cerebellar gangliocytoma, also known as Lhermitte-Duclos disease. This cerebellar tumor, while extremely rare in incidence, is classified as the most common type of brain lesion in adult patients with Cowden syndrome. This report will also include a comprehensive literature review of Cowden syndrome and Lhermitte-Duclos disease, with greater emphasis on the radiologic characteristics of Lhermitte-Duclos disease.
