The value of intra-operative ultrasound as a tool in guiding resection of cerebral gliomas and the relationship between the appearance of brain tissue on intra-operative ultrasonography and pathological grade of cerebral glioma were investigated in 98 patients who underwent neurosurgical tumour removal. Lesions were classified according to pathological grade. Intra-operative ultrasonography orientated all the cerebral gliomas accurately and helped the neurosurgeon in assessing the tumour prior to removal. All lesions were hyperechoic compared with normal brain tissue, and the majority of lesions displayed irregular shapes and indistinct margins. Different pathological grades of glioma presented different ultrasonographic appearances. The majority of low-grade (I and II) cerebral gliomas were homogeneous, with distinct margins and clear surrounding oedema compared with adjacent brain tissue. High-grade (III and IV) cerebral gliomas mostly exhibited poorly defined borders and central necrosis, and the surrounding oedema was difficult to distinguish from the lesions. Residual tumour or haematoma were identified. In conclusion, intra-operative ultrasonography is of great value in locating and assessing the grade of cerebral glioma, and is conducive to enabling early evaluation and total removal of the lesion.
