Imaging of cerebellopontine angle lesions: an update. Part 1: enhancing extra-axial lesions (original) (raw)

Cerebellopontine angle (CPA) lesions, clinically non-specific, require imaging for accurate preoperative diagnosis due to their varied cell types and origins. With vestibular schwannomas being the most common CPA lesions, advanced imaging techniques such as diffusion-weighted imaging (DWI), perfusion imaging, and MR spectroscopy are crucial in differentiating these lesions. This review focuses on enhancing extra-axial lesions in the CPA, providing insights into their imaging characteristics, an algorithm for diagnosis, and advanced imaging findings.
