- Abstract
- Three-dimensional. computed tomographic angiography (CTA), a representative noninvasive radiologic technique, is being widely used for detecting vascular Lesions in specific intracranial bleeding under a certain circumstance (acute nontraumatic subarachnoid hemorrhage). We encountered a case of extravasation of the contrast medium on CTA images that appeared as ribbon-like high-attenuation lesion from an aneurysm at the distal anterior choroidal artery in a young adult moyamoya patient. As CTA is used more frequently, it is imperative to understand such unusual but, potentially Lethal image findings to conduct a prompt intervention.
