Abstract：Objective The association between patent foramen ovale (PFO)and cryptogenic stroke (CS) and the characteristics of infarction on diffusion -weighted imaging ( DWI ) aid in PFO are discussed.Methods The clinical data of 139 cases with cryptogenic stroke , who admitted to Department of Neurology , Xijing Hospital , were analyzed retrospectively.All the subjects were divided into two groups:group with PFO (n=91, 65.5%) and group without PFO ( n =48, 34.5%).Diffusionw-eighted imaging of brain Magnetic Resonance Imaging ( MRI )was performed by two radiologists blinded to clinical data .Rseults The proportion of cryptogenic stroke with PFO was larger than that of the patients without PFO.A single involvement to the subcortical lesions larger than 15 mm was more likely to be PFO-associated (P<0.05).In addition, the majority of infarcts involved in middle cerebral artery in both groups.Conclusion The different diffusion-weighted imaging characteristics between group with PFO and group without PFO suggest that PFO is related to cryptogenic stroke .A single and larger than 15 mm subcortical infarct seems to favor PFO as a stroke etiology.
