Summary
Unilateral hydrocephalus, a rare condition causing one-sided lateral ventricle dilation in adults, can result from foramen of Monro obstruction. This leads to increased intracranial pressure symptoms.
Area of Science:
- Neurology
- Neurosurgery
- Medical Case Reports
Background:
- Unilateral dilatation of the lateral ventricle is an uncommon finding in adult neuroimaging.
- Hydrocephalus, characterized by excess cerebrospinal fluid accumulation, typically affects both ventricles.
- Obstruction at the foramen of Monro can lead to ventricular enlargement.
Observation:
- This report details two adult cases presenting with unilateral hydrocephalus.
- The underlying cause in both cases was identified as an obstruction at the foramen of Monro.
- Patients exhibited clinical signs and symptoms indicative of elevated intracranial pressure.
Findings:
- Confirmed unilateral hydrocephalus due to isolated foramen of Monro obstruction.
- Demonstrated a correlation between this specific obstruction and raised intracranial pressure.
- Highlighted the diagnostic and clinical presentation in a rare adult presentation.
Implications:
- Suggests that unilateral hydrocephalus, even in adults, warrants thorough investigation for localized obstructions like those at the foramen of Monro.
- Emphasizes the importance of recognizing this rare entity to ensure timely diagnosis and management of increased intracranial pressure.
- Contributes to the limited literature on unilateral hydrocephalus, aiding in understanding its pathophysiology and clinical course.
