Abstract:
Primary intraventricular hemorrhage (PIVH) imaged by magnetic resonance imaging (MRI) is reported. A fifty-seven-year-old man with long-standing hypertension suddenly developed severe headache, vomiting, and retrograde amnesia. A computed tomography scan on the same day revealed hematoma in the right posterior horn of the lateral ventricle and in the 4th ventricle. Angiography of the neck and head failed to demonstrate any vascular abnormalities. On the second day his neurological symptoms almost recovered except for the loss of the memory of the ictal day. High-field MRI on the sixteenth day demonstrated an isointense lesion surrounded by a hypointense area in the T1 weighted image or a hyperintense lesion in the T2 weighted image, suggesting subacute hematoma consistent with hypertension, just anterior to the right trigone of the lateral ventricle.
Insights
Primary intraventricular hemorrhage (PIVH) in a hypertensive patient was visualized using MRI. The study details the imaging findings of a subacute hematoma in the lateral ventricle.
Area of Science:
- Neurology
- Radiology
- Medical Imaging
Background:
- Primary intraventricular hemorrhage (PIVH) is a critical neurological event.
- Hypertension is a significant risk factor for cerebrovascular diseases.
Observation:
- A 57-year-old male with hypertension presented with acute neurological symptoms including headache, vomiting, and amnesia.
- Initial CT scan revealed intraventricular hemorrhage; angiography showed no vascular abnormalities.
- High-field MRI demonstrated characteristic findings of subacute hematoma in the lateral ventricle.
Findings:
- MRI revealed an isointense lesion on T1-weighted images and a hyperintense lesion on T2-weighted images.
- These findings are consistent with a subacute hematoma located anterior to the right trigone.
- The imaging findings correlated with the clinical presentation of PIVH secondary to hypertension.
Implications:
- This case highlights the utility of MRI in characterizing PIVH.
- Understanding the imaging features of subacute hematoma is crucial for diagnosis and management.
- The findings underscore the link between hypertension and intraventricular hemorrhage.
