A rare case of scimitar syndrome with pulmonary arterial hypertension in an adult female.

Scimitar syndrome is a rare congenital anomaly characterized by partial or total anomalous pulmonary venous drainage of the right lung to the inferior vena cava. We report a case of a 67-year-old female who presented with cough and dyspnea and was diagnosed with scimitar syndrome and pulmonary arterial hypertension based on comprehensive imaging and hemodynamic evaluation. This case highlights the importance of considering scimitar syndrome as a cause of pulmonary hypertension even in adult patients.
