Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: technique: ct imaging of the head performed before and after the intravenous administration of 150 cc of optiray. nonionic contrast was used due to patient allergies. additional reformatted imaging in multiple planes was also performed. ct head w/o contrast: a large amount of subarachnoid blood is present within the suprasellar space, as well as within basilar cisterns, the sylvian fissure, as well as within the posterior horns of both lateral ventricles. there is no evidence of hydrocephalus of shift of normally midline structures. the differentiation of the and white matter is preserved with no evidence of acute major vascular territorial infarction. bone windows show no suspicious lytic or sclerotic lesions. cta head: a 4-5 mm bilobed aneurysm is present originating from the left aspect of the anterior communicating artery directed inferiorly. a diminutive right a-1 segment is present. both vertebral, internal carotid, middle cerebral artery, posterior cerebral artery, and anterior cerebral arteries are well-opacified. no additional aneurysms are identified. the basilar artery is patent. a left dominant vertebral arterial system is present. no abnormal enhancement is seen within the brain. ct reconstructions: images were formated in multiple planes were essential in evaluating the patient's cerebral vasculature and demonstrate a bilobed aneurysm originating from the left aspect of the anterior communicating artery. impression 1. 4-5 mm bilobed aneurysm originating from the left aspect of the anterior communicating artery. 2. associated diffuse subarachnoid hemorrhage as well as a small amount of blood within the lateral ventricles.

Answer: The patient is high likely exposed to
