From: Role of contrast-enhanced FLAIR MRI in diagnosis of intracranial lesions
Male patient aged 26 years with histopathologically proven right-sided vestibular schwannoma. A, B Axial pre-contrast T1WI and FLAIR respectively showed well defined extra-axial space-occupying lesion centered at the right cerebellopontine angle (CPA). It displayed low signal intensity on T1WI and intermediate signal intensity on FLAIR image. C Axial post-contrast T1WI showed peripheral non-homogenous enhancement with predominant internal non-enhancing cystic component. D Axial post-contrast FLAIR showed more extensive heterogeneous enhancement of the mass signifying a more solid component of the tumor. In addition, intra-canalicular extension into the internal auditory canal was more clearly demonstrated (trumpeting of the porus acousticus)
