    Abstract:
    This report describes an oligoastrocytoma in the brain of a 3.5-year-old female pet African hedgehog (Atelerix albiventris) that showed progressive central nervous system signs for 6 months. Microscopical examination of the brain revealed a widely infiltrative, deep-seated glioma within the white matter of the cerebral hemispheres, basal nuclei, hippocampus, thalamus, midbrain, pons and the medulla of the cerebellum with extension of neoplastic cells into the cerebral cortex and overlying leptomeninges. Morphological features of the neoplastic cells, together with variable immunohistochemical expression of glial fibrillary acidic protein, Olig-2 and Nogo-A, indicated the presence of intermingled astrocytic and oligodendroglial tumour cells with an astrocytic component of approximately 40% consistent with an oligoastrocytoma. The distribution of the tumour is consistent with gliomatosis cerebri.
