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.
报道了通过磁共振成像（MRI）成像的原发性脑室内出血（PIVH）。一名患有长期高血压的57岁男性突然出现严重头痛、呕吐和逆行性遗忘。同一天的计算机断层扫描显示侧脑室右后角和第四脑室内有血肿。颈部和头部血管造影未显示任何血管异常。第二天，除了发作日的记忆丧失外，他的神经症状几乎完全恢复。第16天的高场MRI显示，在T1加权图像中，等强度病变被低强度区域包围，或在T2加权图像中为高强度病变，提示与高血压一致的亚急性血肿，位于侧脑室右三角区前方。
