Cavernous angioma in the fourth ventricular floor--case report.
Neurologia Medico-Chirurgica
|February 1, 1991
Summary
A rare fourth ventricle cavernous angioma caused severe symptoms. Surgical removal resolved the patient's neurological deficits, highlighting the importance of advanced imaging.
Area of Science:
- Neurology
- Neurosurgery
- Radiology
Background:
- Cavernous angiomas are rare vascular malformations.
- Fourth ventricle floor location is exceptionally uncommon.
- Symptoms can include headache, vomiting, diplopia, and dysarthria.
Observation:
- A 44-year-old female presented with occipital headache, vomiting, diplopia, and dysarthria.
- Computed tomography revealed a high-density lesion in the fourth ventricle with hydrocephalus.
- Magnetic resonance imaging demonstrated a mixed-intensity mass on T2 and high/isointensity on T1.
Findings:
- The lesion was surgically removed and confirmed as a cavernous angioma.
- Postoperative recovery showed gradual resolution of ataxic gait, nausea, and vomiting.
- Magnetic resonance imaging proved crucial for assessing the lesion's relationship with the brainstem.
Implications:
- Complete surgical resection of fourth ventricle cavernous angiomas can lead to excellent outcomes.
- Advanced neuroimaging, particularly MRI, is vital for diagnosis and surgical planning.
- This case underscores the importance of considering rare pathologies in the differential diagnosis of posterior fossa lesions.
