MRI-guided stereotactic supratentorial lesion biopsy:a report of 103 patients / 中国肿瘤临床

ABSTRACT

To evaluate the reliability and accuracy of MRI-guided stereotactic biopsy for supratentorial brain lesions. Method: A total of 103 cases of MRI-guided biopsy were performed between November 2009 and December 2013. Patients' pathological results and postoperative rehabilitation courses were analyzed. Results: A total of 102 patients (99.0%) had pathological results, of which 97 cases were brain tumors (86.0%), including 36 cases of astrocytoma, 9 cases of anaplastic astrocytoma, 10 cases of oligoastrocytoma, 4 cases of anaplastic oligoastrocytoma, 4 cases of anaplastic ligodendroglioma, 3 cases of glioblastoma multiforme, 27 cases of lymphoma, 3 cases of germcell tumors, and 1 case of rhabdomyosarcoma. Inflammatory lesions were found in 3 cases (2.9%). Displacement of brain gray matter was reported in 2 cases (2.0%), and 1 case (1.0%) of cerebral infarction existed. A total of 3 patients suffered intracranial hematoma after biopsy, and 1 patient underwent craniotomy to remove the hematoma. No death or intracranial inflammation occurred after biopsy.Conclusion: MRI-guided stereotactic biopsy is a safe and reliable method in qualitative diagnosis. It is a very important tool for diagnosis and treatment selection for intracranial lesions.
