Is the brain biopsy obligatory or not for the diagnosis of Schilder's disease? Review of the literature.

Clinical features and neuroimaging findings of this disease might mimic an intra-cranial mass lesion including an abscess or a tumour. CASE REPORT: Clinical and radiological findings of two children with the diagnosis of Shilder's disease are reported, and the role of brain biopsy as a diagnostic tool is discussed.
