From left to right: coronal CTA, sagittal CTA, and coronal MIP (Maximum Intensity Projection). The images reveal a ruptured giant arteriovenous malformation located in the left middle

Clinical Differential Diagnosis Multisystem disorders with café-au-lait spots include various RASopathies such as neurofibromatosis type 1 (NF1), neurofibromatosis type 2 (NF2), Noonan syndrome, Noonan syndrome with multiple lentigines (LEOPARD), and Legius syndrome. In NF1, the café-­au-lait spots have a smooth “coast
