Insights
This case study describes a rare cerebellar tumor, dysplastic gangliocytoma (Lhermitte-Duclos disease), in a young male. Surgical removal was successful, offering insights into this unusual neurological condition.
Area of Science:
- Neurology
- Neurosurgery
- Pathology
Background:
- Lhermitte-Duclos disease is a rare, benign tumor characterized by cerebellar thickening.
- It often presents with symptoms of elevated intracranial pressure due to mass effect.
Observation:
- A 30-year-old male presented with a 3-month history of elevated intracranial pressure and right-sided hearing loss.
- CT and MRI revealed a large, calcified, non-enhancing cerebellar mass with unusual septations causing hydrocephalus.
Findings:
- Surgical excision of the poorly demarcated lesion was performed.
- Histopathological examination confirmed the diagnosis of dysplastic gangliocytoma (Lhermitte-Duclos disease).
Implications:
- This case highlights the importance of considering rare cerebellar tumors in the differential diagnosis of hydrocephalus.
- Understanding the clinical and radiological features aids in timely diagnosis and surgical management of Lhermitte-Duclos disease.
Abstract:
The case of a 30-year-old male patient is presented who was admitted with a 3-month history of elevated intracranial pressure and reduced-hearing on the right. CT revealed hydrocephalus due to displacement of the 4th ventricle by a large non-enhancing cerebellar mass with calcifications. MRI sequences showed a space-occupying lesion within the right cerebellar hemisphere with unusual septations. At operation, the poorly demarcated lesion was excised from the apparently normal surrounding cerebellar tissue and histologically proven to be a dysplastic gangliocytoma (Lhermitte-Duclos disease). Clinical and neuroradiological appearance of this rare entity, as well as hypotheses on its pathogenesis are discussed.
