CT-guided needle biopsy of intracranial tumours: results in 118 consecutive patients.
The purpose of this paper is to evaluate the efficacy and safety of CT-guided needle biopsies and to determine the optimal indications for this technique. The case histories of 118 patients who underwent a CT-guided biopsy for brain lesions during a six-year period, from November 1986 to September 1992, were reviewed. During a preliminary CT-scan, the entry site was determined and localized using a radio opaque marker and the safest route to the lesion was chosen. One hundred and thirty four procedures were performed in 118 patients. A positive diagnosis of tumour was obtained in 106 patients (89.8%). Repeat procedures were required in 18 patients. High-grade gliomas were the more common lesions (55.1%). Morbidity and mortality was assessed over the 30-day period after the procedure. Nine patients died during this time. Eight patients from day 3 to day 30 in the expected course of their disease and one within 48 first hours from neurological deterioration following the procedure. We found that CT-scan guided biopsies are a safe and accurate way to obtain brain tissue specimens for pathological diagnosis in selected cases. For superficial and large tumours it is a simple, fast and effective procedure.
