Summary
Frame-based stereotactic biopsy using computerized planning achieved a 97% diagnostic success rate for intracerebral lesions. This accurate method for defining brain lesion coordinates offers a safe and effective approach for neuropathological examination.
Area of Science:
- Neurosurgery
- Neuropathology
- Medical Imaging
Background:
- Space-occupying intracerebral lesions require accurate diagnosis.
- Traditional stereotactic biopsy methods can be limited by coordinate definition accuracy.
Purpose of the Study:
- To evaluate the efficacy and safety of a computerized planning technique for frame-based stereotactic biopsy.
- To assess the diagnostic yield of stereotactic biopsy for intracerebral lesions using this method.
Main Methods:
- 37 patients with intracerebral lesions underwent frame-based stereotactic biopsy.
- Computer-aided planning was used for CT-localization and defining entry/target coordinates.
- Serial biopsies were performed for neuropathological examination.
Main Results:
- A high diagnostic yield of 97% (36/37 patients) was achieved.
- Intraoperative bleeding occurred in only 8.1% of patients (3/37) with no significant complications.
- Computerized planning facilitated accurate definition of coordinates.
Conclusions:
- Computer-supported stereotactic biopsy is a safe and effective method for diagnosing intracerebral lesions.
- The high diagnostic accuracy and safety profile support its routine use in neurosurgical practice.
