Idiopathic Pulmonary Arterial Hypertension Was Diagnosed Initially by the Computed Tomographic Angiogram.

Idiopathic pulmonary arterial hypertension (IPAH) is a rare and progressive disease with non-specific signs and symptoms. A 50-year-old woman with IPAH presented to the emergency department (ED) with a complaint of episodic dyspnea that had persisted for the previous two months. Based on the fi ndings of the initial chest computed tomographic angiography conducted in the ED, we suspected pulmonary hypertension. IPAH was eventually confi rmed following a series of investigations, including right heart catheterization. The history of this interesting case is reported with a review of the relevant literature.
