Vein of Galen aneurysm (VGAM) is a rare vascular malformation accounting for less than 1% of all intracranial abnormalities. In this case report, we performed computed tomography (CT) and magnetic resonance imaging (MRI) examinations for a 26-year-old female patient who presented with a severe headache. On these images, a right thalamo-choroidal arterio-venous malformation (AVM) with secondary aneurysmal dilatation of the vein of Galen was suspected, and a CT angiography was performed for further evaluation, which confirmed the diagnosis. The patient refused digital subtraction angiography (DSA) and probable endovascular treatment. Although it is rarely seen in the adult population, CT and MRI have a tremendous impact on the diagnosis of these patients. We should also emphasize the role of CT angiography in the diagnosis and further evaluation of these vascular malformations. Endovascular therapy is regarded as an effective and safe technique in the treatment of these patients.
