A 55-year-old man with congenital hemiparesis of the right side, three episodes of generalised tonic-clonic seizure at 16 years of age, and two episodes of severe depression and two episodes of hypomania in the past, presented with severe depression with psychotic symptoms. Computed tomography of the brain showed a grey matter-lined cerebrospinal fluid-filled cleft in the left cerebral hemisphere, involving the temporoparietal region. He was diagnosed to have bipolar II disorder, and was currently severely depressed with psychotic symptoms and schizencephaly. He improved with sodium valproate 1,000 mg/day, quetiapine 450 mg/day and escitalopram 20 mg/day after three weeks without any emergent side effects, and was maintaining well at three months follow-up. Although uncommon, schizencephaly may be considered as one of the differentials in cases of bipolar disorder along with congenital hemiparesis, mental retardation and/or seizures; and neuroimaging should be done to confirm the diagnosis.
