A ventricular diverticulum was found on computed tomography in six out of 25 cases of congenital obstructive hydrocephalus. In all six cases, the diverticulum was located on the medial wall of the trigone. In three cases, it was restricted to the tentorial hiatus with a recognisable superior cerebellar cistern (small). In two cases, it occupied the tentorial hiatus without a recognisable cistern (medium). The remaining case had a diverticulum extending into the posterior fossa that caused cerebellar ataxia (large). In all patients, the diverticulum regressed after ventriculo-peritoneal shunt. The characteristics of the computed tomograms, the clinical significance and the pathogenesis of this phenomenon are discussed.
在25例先天性梗阻性脑积水患者中，计算机断层扫描发现6例存在脑室憩室。所有6例中，憩室均位于三角区内侧壁。3例憩室局限于小脑幕裂孔，伴有可识别的小脑上池（小）。2例憩室占据小脑幕裂孔，无明显的脑池（中）。其余1例憩室延伸至后颅窝，导致小脑性共济失调（大）。所有患者在脑室-腹腔分流术后憩室均消退。本文讨论了计算机断层扫描的特征、这一现象的临床意义及发病机制。
