Cerebral venous thrombosis revealed by psychiatric disorders: a diagnosis not to be missed

BACKGROUND: Cerebral Venous Thrombosis (CVT) is a rare condition. Diagnosis must be made urgently despite highly varied neurological symptoms, initially dominated by headaches. In some cases, CVT may have an unusual presentation, making diagnosis difficult. A purely psychiatric manifestation is exceptional and can lead to diagnostic uncertainty and delay. Diagnosis is radiological and treatment is based on early anticoagulation. The prognosis for CVT is much better than that for cerebral infarcts of arterial origin. CASE PRESENTATION: We present a case of postpartum cerebral thrombophlebitis with late diagnosis revealed by psychotic disorders, which had a favorable outcome. CONCLUSION: Cerebral Venous Thrombosis (CVT) is a rare and urgent thrombotic vascular disease. Its clinical presentation is varied. The diagnosis must be considered in the presence of any acute psychiatric manifestation during the postpartum period.
