Intraoperative real-time ultrasonic sector scanning was performed through the unincised dura mater or the intact brain surface of eight patients (aged six months to 13 years), each of whom had a previously documented mass lesion (four supratentorial, three infratentorial, one intraventricular). In each case, there was a clear definition of the location, configuration, and tissue consistency of the mass. With the exception of a choroid plexus papilloma, all lesions demonstrated both solid and fluid components. The location of a subcortical parietal lobe mass (ependymoma) was apparent only by prior sonography. All neoplastic tissue of one cerebellar astrocytoma that was identified at gross examination was removed, but additional intraoperative scanning following removal of the neoplasm suggested the presence of residual abnormal tissue. This was confirmed during further exploration, and additional gross tumor tissue was excised.
对8例患者（年龄6个月至13岁）通过未切开的硬脑膜或完整的脑表面进行术中实时超声扇形扫描，这些患者之前均记录有占位性病变（4例幕上病变、3例幕下病变、1例脑室内病变）。在每例病例中，均能清晰界定肿块的位置、形态及组织质地。除脉络丛乳头状瘤外，所有病变均显示有实性和液性成分。仅通过术前超声检查才明确了1例皮质下顶叶肿块（室管膜瘤）的位置。1例小脑星形细胞瘤在大体检查时发现的所有肿瘤组织均被切除，但肿瘤切除后进行的术中额外扫描提示存在残留异常组织。在进一步探查时得以证实，并切除了额外的大体肿瘤组织。
