Abstract
A patent foramen ovale (PFO) is a congenital cardiac lesion that can cause migraines with aura and stroke (1). Echocardiography is a first line diagnostic imaging modality for PFO (2). However, CT techniques have been improving, and some interesting papers demonstrating that PFO can be diagnosed by ECG-gated cardiac CT angiography have been published (3, 4). They reported that it is less sensitive to detect PFO by CT than by echocardiography. Recently, using cardiac multidetector row CT (MDCT), we detected PFO in a male adolescent patient. The PFO had been the hidden cause of a longstanding migraine.
