“…Stereotactic brain biopsy in conjunction with CT or MR imaging is used routinely in humans to provide a diagnosis, to plan treatment, and to formulate the prognosis 6–9 . Various techniques have been described in veterinary medicine, but have been used to a lesser degree in the clinical setting 10–18 .…”

This report describes computed tomography (CT)-guided stereotactic brain biopsy using the Kopf stereotactic system, a commercially available patient restraint system which does not require additional modification for use in small animals. The accuracy of biopsy needle placement was determined by injecting dilute iohexol into cadaver brains and comparing the three-dimensional coordinates of the desired target location to the actual needle tract observed on postcontrast CT images. Overall mean error in needle placement in a dorsoventral trajectory was 0.9 +/- 0.9 mm (n = 80 injections) for dogs and 1.0 +/- 1.1 mm (n = 30 injections) for cats. The overall mean error in needle placement via an oblique trajectory in five dogs was 1.7 +/- 1.6 mm (n = 12 injections). These results suggest that this system can be used to successfully place a biopsy needle into the brain to obtain biopsies from small lesions.

A 20-year-old male presented with symptoms of isolated neurosarcoidosis including epilepsy. Magnetic resonance imaging disclosed multiple enhanced right temporal and frontal lesions. Cerebrospinal fluid examination identified mild lymphocytic pleocytosis, and histological examination of a stereotactic brain biopsy specimen demonstrated noncaseating granulomas, so fungal or other inflammatory or granulomatous diseases were excluded. The diagnosis was cerebral sarcoidosis, despite the absence of systemic manifestations. Corticosteroid therapy improved his neurological state and radiological findings. Neurosarcoidosis is a well-recognized occurrence in systemic sarcoidosis, but diagnosis may be difficult in the absence of extracerebral manifestations.

“…Especially the risk of inaccurate diagnosis in the case of brain tumor heterogeneity was the main argument despite the wide use and eYciency of stereotactic biopsy (Robbins et al 1994;Franzini et al 1994). Therefore, only very carefully considered cases should be forwarded for stereotactic biopsy.…”
