Intraoperative real-time ultrasound was used to assist localization and surgical removal of colloid cysts in patients without ventriculomegaly. In the most commonly used surgical approach for removal of colloid cysts, dilated lateral ventricles can expedite the localization of lesions because, once entered surgically, a dilated ventricle offers more space near the foramen of Monro in which to work. Additionally, the enlargement of the foramen of Monro, seen with hydrocephalus, provides greater accessibility to the colloid cyst. In patients with symptoms related to the colloid cyst. In patients with symptoms related to intermittent obstruction of cerebral fluid flow but with normal-sized ventricles, the precise localization of the foramen of Monro and colloid cyst is more difficult and may result in unnecessary exploration/resection of brain. Using intraoperative ultrasound, the colloid cyst and adjacent anatomic structures can be clearly visualized regardless of ventricular size. Intraoperative ultrasonography has a unique role in the operative treatment of patients with colloid cysts and nondilated ventricles.
术中实时超声用于辅助无脑室扩大患者胶体囊肿的定位及手术切除。在最常用的胶体囊肿切除手术入路中，扩张的侧脑室可加快病变定位，因为一旦通过手术进入，扩张的脑室在室间孔附近提供了更多操作空间。此外，脑积水时可见的室间孔扩大，使胶体囊肿更易于触及。对于有胶体囊肿相关症状的患者。对于有脑脊液流动间歇性梗阻相关症状但脑室大小正常的患者，室间孔和胶体囊肿的精确定位更困难，可能导致不必要的脑探查/切除。使用术中超声，无论脑室大小如何，均可清晰显示胶体囊肿及相邻解剖结构。术中超声在胶体囊肿且脑室未扩张患者的手术治疗中具有独特作用。
