Sequencial imaging assessments showed a large left infratentorial arachnoid cystic lesion that was being monitored. ( Figure 1).
Head computed tomography (CT) scan showed the pre-existing cystic lesion in the left cerebellopontine angle with a slight right brainstem deviation, without associated edema (
2A), as confirmed by magnetic resonance imagining (MRI) (
2B).
