Abstract:
Objective To investigate the clinical value of stereotactic biopsy in the diagnosis of the multiple intracranial lesions, and explore the operation methods, technical points and clinical experiences to reduce surgical complications. Methods Twenty-three patients in the first affiliated hospital of Kunming Medical University underwent stereotactic biopsy from January 2009 to June 2013 were analyzed retrospectively. The patients were aged between 11 and 73 years (the mean age of 34.6 years) . There were 12 males and 11 females. Operations were performed by thin thickness of spiral CT scan, ASA-602S and Leksell-Frame-G stereotactic frame, Sedan side-cutting needle, Backlund side-cutting needle and neuroendoscope of STORZ. Routine histopathological examinations of specimens were conducted. The immunohistochemical staining of the histopathological section of specimens was performed if necessary. Results The diagnostic yield was 91.3% (21 cases) . The result of pathological diagnosis was inflammatory granuloma in 1, inflammatory lesion in 1, calcification in 1, hyperplasia of colloid cells in 6, astrocytoma in 1 (WHOⅠ-Ⅱ), astrocytoma in 2 (WHOⅡ), astrocytoma in 1 (WHOⅡ-Ⅲ), mixed oligoastrocytoma in 1 (WHOⅠ-Ⅱ), glioblastoma multiforme in 3 (WHOⅣ), germinoma in 1, brain metastases in 1, diffuse large B-cell lymphoma in 1, intracranial granulomatousarteritis in 1 and negative in 2. There were no serious complications, such as coma, hemiparalysis, infection and intracranial hematoma. Conclusion Stereotactic biopsy is an important method in the diagnose of multiple intracranial lesions. It has the advantages of precise location, less damage, safe performance, and reducing the complication effectively. It is worth promoting.
