Transient mutism and cerebellar ischemic stroke: case report

Abstract

The ischemic stroke is one of the most common conditions in our hospitals, representing 50% of revenues of neurology services. A variety of processes is cerebral ischemic myocardial cerebellum. Cerebellar infarction is not a rare disease, representing between 2 to 4% of all cerebrovascular events in clinical and autopsy series, and their ratio is 4-5 times higher than cerebellar hemorrhage. Although it is increasingly documented, it rarely Recognized stills like a phenomenon. Mutism occurs primarily in children and occasionally in adults as a well-recognized complication of posterior fossa surgery. Rarely been reported transient mutism associated with cerebellar infarction as isolated episode

A case of cerebellar mutism initially diagnosed as adjustment disorder with anxiety

“…CM may develop in 11.0-29.0 % of children after surgeries involving the posterior fossa and is especially seen among patients with medulloblastomas and/ or brainstem lesions 4 . However, cases developing after ischemic strokes involving the cerebellum have also been described 5 .…”

“…In CM patients who were operated on for tumors, typically, the speech is normal for a brief period after surgery and deteriorates thereafter. In the majority of patients, mutism resolves after weeks to months although it may persist longer in some 5 . The exact pathophysiology of CM is unclear and features of the syndrome may be interpreted as psychological in origin.…”
