title: CT computerised stereotactic biopsy for low density CT lesions presenting with epilepsy.
abstract: Thirty five patients presenting with epilepsy alone and non-enhancing low-density lesion on the CT scan underwent a computer-assisted CT-guided stereotactic biopsy with stereotactic angiographic control. There was no mortality or morbidity in this series and the diagnostic yield was 97%. Thirty four patients had low grade intra-axial neoplasms. After an estimation of the pathological extent of the tumour, three patients underwent a computer-assisted stereotactic laser resection and 28 patients had radiotherapy.
