Application of stereotactic biopsy under MRI guidance to the diagnoses of intracranial lesions (report of 23 cases)
Abstract：Objective To explore the vaue of MRI-guided stereotactic biopsy to the diagnoses of intracranial lesions, especially to multiple and deep lesions. Methods MRI-guided stereotactic biopsy was performed with the help of stereotactic system and surgical planning software in 25 patients with intracranial lesions from January, 2009 to March, 2015. The outcomes of the intraoperative and postoperative histological examinations helped doctors to make effective therapeutic plan. Results Of 24 cases of intracranial lesions, 9 were diagnosed as astrocytomas, 3 gliomas, 1 glioblastoma, 5 lymphomas, 1 low-grade malignant tumor, and 1 gliocyte proliferation only by the stereotactic biopsy, and 1 was diagnosed as cerebral gliomatosis, 1 lymphoma, 1 brain abscess, and 1 disseminated white-matter encephalopathy by the stereotactic biopsy combined with the clinical and other examinations. There were not positive findings by stereotactic biopsy in another patient who was suspected of having intracranial lesion before the biopsy. The biopsy complications included a small amount of cerebral hemorrhage in 6 patients who were cured by conservative treatment and 30 ml hemorrhage in the left frontal lobe in 1 patient who was cured by emergency decompressive craniotomy and evacuation of hematoma. Conclusions The stereotactic biopsy, which is of great value to the diagnoses of intracranial multiple and deep lesions, has high security, but the risk of cerebral hemorrhage caused by the stereotactic biopsy should be avoided as possible in the patients with intracranial lesions.
