Recent studies have identified that MMD can affect the extracranial pulmonary artery, presenting as MMD with pulmonary arterial hypertension. Some reports illustrated that Ring finger protein 213 (RNF213), considered to be a novel susceptibility gene for MMD in East Asia, has strong correlations with pulmonary arterial hypertension. Therefore, this review encapsulates current cases of MMD with pulmonary arterial hypertension and discusses MMD with pulmonary arterial hypertension in the aspects of epidemiology, pathology, possible pathogenesis, and clinical manifestations.
