AbstractUnilateral cerebellar aplasia is a very rare developmental disorder usually most commonly seen in children after a prenatal insult. It hasmultifarious clinical presentations ranging from development delay to ataxia and cognitive impairment. Here we present a case of a 31year old adult whopresented with acute confusional state (probable seizure) have incidentally found to haveunilateral left cerebellar aplasia. He had normal uneventful delivery with normal development and cognition.Though the exact cause is unknown, even with unilateral cerebellar aplasia there can still have an uneventful life with normal motor activity and intelligence.
