[Hydrocephalus due to a large aneurysm in the basilar artery (author's transl)]
Insights
A basilar artery aneurysm caused obstructive hydrocephalus in a hypertensive patient, leading to neurological symptoms like gait and swallowing difficulties. Surgical intervention is crucial for managing such complex vascular malformations.
Area of Science:
- Neurology
- Neurosurgery
- Vascular Medicine
Background:
- Discusses a rare case of a 66-year-old hypertensive patient with multiple neurological deficits.
- Highlights the importance of considering vascular malformations in the differential diagnosis of obstructive hydrocephalus.
Observation:
- Patient presented with headaches, gait disturbances, dysphagia, dysphonia, and urinary incontinence.
- Computed Axial Tomography (CAT) scan revealed significant dilatation of the entire ventricular system.
- Autopsy identified a large, bisaccular aneurysmal malformation of the basilar artery.
Findings:
- The basilar artery aneurysm compressed the pons and medulla oblongata.
- This compression obstructed the fourth ventricle and cerebral aqueduct.
- The obstruction resulted in obstructive hydrocephalus, explaining the patient's symptoms.
Implications:
- This case underscores the critical link between basilar artery aneurysms and obstructive hydrocephalus.
- Accurate diagnosis and timely intervention are vital for improving patient outcomes in complex neurological cases.
- Illustrates the potential for vascular lesions to cause significant mass effect and secondary neurological dysfunction.
Abstract:
In the light of the literature the authors discuss the case of a 66 year-old hypertensive patient presenting headaches, disorders of gait and deglutition, dysphonia and urinary incontinence. A CAT scan showed dilatation of the entire ventricular system. Anatomo- pathological investigation showed a voluminous bisaccular aneurysmal malformation in the basilar artery. By deforming the pons and the medulla oblongata, the aneurysm had compressed the fourth ventricle and cerebral aqueduct, thus causing hydrocephalus. (Acta neurol. belg., 1980, 80, 80-85).
