From: The correlation between patent foramen ovale and brain ischemia in plateau residents
Example of a case with PFO and multiple brain ischemic lesions. One Tibetan female patient with age 25Â years, resident in an area with 3850Â m above sea level, is long-term suffering from headaches and dizziness. Left panel: brain MRI shows low-intensity signal by a coronal section on FLAIR. Middle panel: DWI shows multiple low-intensity lesions in both hemispheres, which are consistent with old infarcts. Right panel: echocardiography imaging of the heart. Arrow points to PFO with diameter of 5.5Â mm
