The patient describes sharp, constant frontal pain with nausea, photophobia, and neck stiffness. Noncontrast computed tomography (CT) scan and clinical examination reveal acute subarachnoid hemorrhage (SAH) with Hunt and Hess grade II, Fisher group 3, and modified Fisher group 4 with bilateral intraventricular hemorrhage (IVH). An emergent external ventricular drain (EVD) was placed when the patient’s mental status deteriorated to a drowsy, difficult-to-arouse state along with radiographic evidence of worsening IVH and hydrocephalus.
