The clinical and computed tomographic (CT) findings in 100 consecutive adult nontraumatic intraventricular hemorrhage (IVH) cases are analyzed. There were 74 parenchymal brain hemorrhages with secondary ventricular extension. The ventricles were filled with blood and asymmetrically enlarged. If the hemorrhage involved putamen, cerebellum, pons, or subcortical cerebral hemispheric white matter, IVH was associated with large parenchymal hematomas; these patients had poor clinical outcome. With thalamic or caudate hematomas, IVH frequently occurred with large hematomas but may occur with small hematomas. The small hematomas were located directly contiguous to the ventricular walls and caused extensive ventricular blood. Patients with small thalamic and caudate hemorrhage with intraventricular blood had good clinical outcome; whereas patients with large hematomas had poor outcome. Primary IVH occurred in 24 cases. In these cases, blood was seen in all ventricular chambers. Aneurysms involving the anterior cerebral-anterior communicating artery region were the most common etiology for primary IVH.
分析了连续100例成人非创伤性脑室内出血（IVH）病例的临床及计算机断层扫描（CT）结果。有74例脑实质出血伴继发性脑室扩展。脑室充满血液且不对称扩大。如果出血累及壳核、小脑、脑桥或大脑半球皮质下白质，IVH与较大的脑实质血肿相关；这些患者临床预后较差。对于丘脑或尾状核血肿，IVH常伴有较大血肿，但也可能伴有小血肿。小血肿直接毗邻心室壁并导致广泛的脑室积血。伴有脑室内积血的小丘脑和尾状核出血患者临床预后良好；而伴有大血肿的患者预后较差。原发性IVH发生24例。在这些病例中，所有脑室腔均可见血液。累及大脑前动脉-前交通动脉区域的动脉瘤是原发性IVH最常见的病因。
