Lipoma of the quadrigeminal plate causing progressive obstructive hydrocephalus. Case report
Journal of Neurosurgery
|September 1, 1978
Summary
Congenital hydrocephalus in a patient led to progressive mental decline due to a midbrain lipoma obstructing cerebrospinal fluid flow. This case highlights the need for comprehensive neuroimaging in hydrocephalus management.
Area of Science:
- Neuroscience
- Neurology
- Developmental Biology
Background:
- Congenital hydrocephalus is a condition characterized by excessive cerebrospinal fluid accumulation in the brain.
- Patients often present with varied neurological deficits depending on the severity and location of the obstruction.
Observation:
- A patient with congenital hydrocephalus and early-onset poor vision, but normal motor and intellectual development, experienced progressive mental deterioration.
- Necropsy revealed severe hydrocephalus caused by a midbrain tectum lipoma obstructing the aqueduct of Sylvius.
Findings:
- The autopsy also showed absence of the septum pellucidum, a thinned corpus callosum, and atrophy of the anterior visual system.
- These findings suggest a potential link between intracranial lipomas and developmental abnormalities like septo-optic dysplasia.
Implications:
- This case underscores the critical importance of thorough neuroradiological evaluation for congenital hydrocephalus.
- Investigating the association between intracranial lipomas and conditions like septo-optic dysplasia may improve diagnostic and therapeutic strategies.
