ABSTRACT: Giant aneurysms are thought to represent about 5-8% of all intracranial aneurysms. Size does not influence the hemorrhage rate, and approximately 25% of patients present with subarachnoid hemorrhage. Seventy to seventy-five percent of patients with giant aneurysm present with mass effect, usually manifest by visual failure, cranial nerve dysfunction, hemiparesis, seizure or headache. Thrombosis and stroke due to blood clot formation within the aneurysm and subsequent distant embolus, occurs in some 2-5% of patients with giant aneurysms. This is a case of a 56 year old female who is a known hypertensive and a known case of cervical cancer stage IIB status post 2 cycles of chemotherapy (2016) and 2 cycles of radiotherapy who presented with blurring of vision OD, headache and dizziness. Imaging modality such as CT angiography was done which revealed a diagnosis of giant cerebral aneurysm at the clinoid portion of the right internal carotid artery with sign of thrombosis.Intracranial masses are classified either as intra-axial or extra-axial lesions. In this case, the possibility of an intra-axial lesion such as metastasis and extra-axial lesions being meningioma as the most common and vascular lesions such as intracranial aneurysms was considered.Imaging modalities such as magnetic resonance or CT angiography help narrow differential diagnoses by providing lesion characteristics and showing distinctive findings of specific diseases. Treatment relies on prompt diagnosis and emergent management
