A case of an elderly adult presenting with obstructive hydrocephalus secondary to a rare hemorrhagic suprasellar pilocytic astrocytoma.

In this report, we present a 65-year-old man who presented with signs and symptoms consistent with impending brain herniation. Emergent imaging revealed a hyperdense mass in the suprasellar region. Urgent surgery was performed and final pathology eventuated a pilocytic astrocytoma. Although rare cases of suprasellar pilocytic astrocytoma in children and adults have been reported, we report an interesting case of a hemorrhagic suprasellar pilocytic astrocytoma in an elderly adult (without prior anticoagulant use) causing impending brain herniation secondary to obstructive hydrocephalus.
