Case Report: A case of craniopharyngioma in the cerebellopontine angle

We report a rare case of craniopharyngioma located in the cerebellopontine angle. A 36-year-old male patient presented with relevant clinical symptoms. Computed tomography (CT) revealed a slightly hypodense mass in the left cerebellopontine angle extending to the ambient cistern. Magnetic resonance imaging (MRI) demonstrated an irregular lesion in the same region, which was slightly hyperintense to isointense on T1-weighted images and heterogeneously hyperintense on T2-weighted images. Diffusion-weighted imaging (DWI) showed mixed signals. The lesion was surgically resected, and the final pathological diagnosis confirmed it as a craniopharyngioma.
