A rare case of dysplastic cerebellar gangliocytoma - Lhermitte Duclos Disease

Abstract

Lhermitte–Duclos disease (LDD), also known as dysplastic cerebellar gangliocytoma, is an uncommon hamartomatous lesion found in the cerebellar cortex. First described by French physicians Lhermitte and Duclos in 1920, this condition involves enlarged cerebellar folia containing abnormal ganglion cells. Clinical manifestations typically include headaches, visual disturbances, and cerebellar dysfunction. While imaging techniques like computed tomography (CT) scans may indicate the presence of mass lesions, magnetic resonance imaging (MRI) is crucial for accurate delineation of the lesion's boundaries and characterization of tissue involvement. Surgical intervention, typically in the form of respective surgery, remains the cornerstone of treatment for LDD. Despite advancements in imaging technologies and surgical techniques, the management of LDD remains fraught with complexities. The prognosis can be variable, and in some cases, despite appropriate therapeutic interventions guided by MRI-assisted surgical planning and confirmation through CT screening, the outcome may be unfavorable, as observed in this instance with the demise of the 50-year-old male patient. Further research and a deeper understanding of the pathophysiology underlying LDD are imperative to enhance diagnostic accuracy, refine treatment modalities, and potentially improve patient outcomes. This case underscores the challenges in managing this rare neurological condition and highlights the need for continued exploration into more effective therapeutic avenues.
