RESUMEN
Objective To investigate the diagnostic value of CT-guided craniocerebral puncture biopsy, and to discuss its clinical safety. Methods During the period from April 2013 to June 2014 at authors’ hospital CT-guided craniocerebral puncture biopsy was carried out in 23 patients. All patients had clinical symptoms or signs of nervous system. Imaging examination revealed that all patients had intracranial space-occupying lesions. CT-guided craniocerebral puncture biopsy was performed to make pathological or bacteriological examinations. The results were statistically analyzed. Results In this group of patients, definite pathological diagnosis was made in 19 cases, biopsy positive diagnosis rate of biopsy was 82.6% (19/23), among them oncology-pathological diagnosis was obtained in 14 cases (60.9%), mainly including glioma, non-Hodgkin lymphoma, dysembryoplastic neuroepithelial tumor, choroid plexus papillary tumor, epidermoid cyst, etc. Non-neoplastic lesion was confirmed in 5 cases (21.7%), including suppurated meningitis, cerebral gliosis hyperplasia, cerebral telangiectasis, etc. Small amount of subdural hemorrhage was observed in one case (4.3%). No severe complications, such as intracranial infection or epilepsy, occurred in all patients. Conclusion CT-guided craniocerebral puncture biopsy is minimally-invasive with fewer complications, it can provide definite diagnosis for intracranial lesions, therefore, this technique has a broad development prospect in clinical practice.
