- W1968962212 abstract "We sought to assess the diagnostic yield, complication rates, and therapeutic impact of open brain biopsy and serial stereotactic brain biopsy in the management of patients with nonneoplastic neurological conditions in which conventional investigations did not yield a definitive diagnosis.A retrospective case note analysis was undertaken in consecutive patients undergoing brain biopsy at The Walton Centre for Neurology and Neurosurgery during a 15-year period. The diagnostic yield, prebiopsy diagnostic category, biopsy technique (open versus stereotactic), complication rates, and impact on clinical management were assessed. Biopsies were grouped into one of five categories: diagnostic, suggestive, nonspecific, normal, or nondiagnostic.Thirty-nine patients underwent biopsy. The diagnostic yield (combined diagnostic and suggestive) of targeted serial stereotactic biopsy was 64% (seven of 11 patients); in the open brain biopsy group, the diagnostic yield was 46% (13 of 28 patients). The prebiopsy diagnosis was confirmed in 100% (three of three patients) stereotactic biopsy patients and 75% (nine of 12 patients) of open biopsy patients. Two patients (7%) in the open biopsy group had short-term complications. The clinical impact was similar in both groups: nine of 28 (32%) open biopsy patients and four of 11 (36%) stereotactic biopsy patients.Despite the low clinical impact, diagnostic brain biopsy should be considered in patients with nonneoplastic undiagnosed neurological disorders. Patients with neuroimaging abnormalities should preferentially undergo targeted biopsy." @default.
