Right cerebellar pilocytic astrocytoma was first discovered on MRI performed 1 month ago, which was operated on and the patient had an uneventful post-op period of 2 weeks, after which another MRI was done and revealed subdural hygromas/chronic hematomas, right cerebellar encephalomalacia and pseudomeningocele. 

One week later, the patient started developing recurrent vomiting, for which non-contrast CT brain was requested. Upon the diagnosis of subfalcine herniation, urgent neurosurgical consultation was advised and the patient was submitted for surgery.
