Intraoperative CT-guided serial microbiopsy of brain lesions and concomitant use of CT air and angiographic studies.
The value of step-by-step confirmation of the location of the brain biopsy probe is demonstrated, using serial CT scanning to confirm the exact source of the sample tissue. Concomitant use of CT angiography and a CT air study makes possible the biopsy of small areas and of areas near major cerebral vessels, as well as of lesions near critical areas like the optic chiasma, basal ganglia, midbrain, and other complex lesions. The pathologist on-line examination of the CT-confirmed serial samples enables the surgeon to obtain the most informative tissue for the ultimate histopathological diagnosis. Our experience with the technique is illustrated by examples of its application in some complex cases.
