The purpose of this study was to evaluate the imaging characteristics of intracranial large and small vessel diseases long after cranial irradiation. All patients with small vessel diseases underwent intracranial vessel wall imaging by 3D high resolution CUBE T1-weighted imaging (HR-MRI) to detect large vessel diseases. All recruited patients were found with intracranial small and large vessel diseases. Therefore, intracranial vasculopathy is not a rare complication after cranial irradiation, even in young patients. Patients after cranial irradiation should be followed up with MR imaging including HR-MRI.
