Brainstem gliomas are relatively rare in adults (<2% of all gliomas). Exophytic gliomas are focal brainstem lesions, which project into the 4 th ventricle or cerebellopontine angles. These exophytic lesions are usually of low-grade histology (pilocytic astrocytoma or ganglioglioma) and have a relatively better outcome compared with brainstem gliomas as a whole. Glioblastoma is the commonest primary glial cell neoplasm and mostly occurs in the supratentorial compartment. It is rather uncommon in the brainstem and seldom has been described as having an exophytic growth pattern. Here we describe an exophytic brainstem glioblastoma arising from the medulla oblongata in a 55-year-old lady who presented with a 4 th ventricular mass, and present a brief review of the literature. Till now, six cases of glioblastoma arising from the medulla oblongata have been reported. So, ours is the seventh such report. To the best of our knowledge, it also happens to be the sixth reported case of dorsally exophytic brainstem glioblastoma till date.
