[Stereotactic biopsy for intracranial deep lesions].
Zhonghua Yi Xue za Zhi [Chinese medical journal] 2002 Februrary 26
OBJECTIVE: To investigate the histological diagnostic efficacy and accuracy of stereotactic biopsy for intracranial deep lesions under computerized tomography (CT) and magnetic resonance imaging (MRI) guidance.
METHODS: CT or MRI-guided stereotactic biopsy was performed in 605 cases with intracranial deep lesions. All the procedures were done under local anesthesia with Leksell stereotactic system. CT or MRI film was used to determine the coordinate in 450 cases and the computer-assisted planning for neurosurgery (CAPN) in 155 cases.
RESULTS: Brain tumors, inflammatory lesions, and abnormal but nonspecific lesions were diagnosed pathologically in 537 cases (88.75%), 30 cases (4.96%), and 13 cases (2.15%) respectively. In 20 cases (3.31%) the biopsy procedure failed to provide useful pathological evidence. The total positive rate of biopsy was 96.69%. Complications associated with biopsy occurred in 18 patients (2.98%), and 2 patients (0.33%) died following the procedure.
CONCLUSION: Stereotactic biopsy using MRI-guided stereotactic approach or CT-guided technique is a safe and reliable method for histological diagnosis of intracranial deep lesions.
