Distal infarction of the left superior cerebellar artery presenting with dysarthria and unsteadiness

Small cerebellar infarction with a benign outcome occurs more frequently than a massive infarction with brainstem compression. Retrospective CT studies have shown it. These infarcts are more often localized in the superior hemisphere of the cerebellum which semiology is not well known. Some reports pointed out that an acute cerebellar infarction in the PICA territory may mimic labyrinthine lesion. The authors report a case of an acute small cerebellar infarction in the SCA territory presenting as a dysarthria and unsteadiness, involving the left lobulus semilunaris superior, in a paravermal zone, on CT scan.
