Right prepontine and cerebellopontine angle space occupying lesion. It shows a small enhancing solid component and large cystic component (tumor associated cyst). The solid component elicits lsointense signal on T1 and T2 WI with post contrast enhancement. It's surrounded by large cystic component eliciting low signal on T1 and high signal on FLAIR and T2 with no post contrast enhancement. The lesion measures collectively 3.1 x 3.4x 2.9 cm along its max Transverse, anteroposterior and craniocaudal dimension. It markedly indents the pons and the 4th ventricle with no hydrocephalic changes.
Radiological findings are suggestive of (preganglionic) trigeminal cystic schwannoma.
