Propensity Score-Matched Analysis of Lesion Patterns in Stroke Patients With Patent Foramen Ovale and Patients With Spontaneous Intracranial Artery Dissection
Conclusion: The present study suggests that lesion patterns observed from DWI of patients with PFO and SIAD might provide clues to the etiology of infarcts. Single lesions (cortical or subcortical) might be a typical feature of PFO associated strokes, while multiple lesions in one vascular territory might be a specific feature of SIAD associated strokes. Introduction Both patent foramen ovale (PFO) and spontaneous intracranial artery dissection (SIAD) are important stroke risk factors, especially in young and middle-aged adults (1–3). About 25% of patients with ischemic stroke are cryptogenic (4), and PFO is ...

Imaging of Spontaneous and Traumatic Cervical Artery Dissection
ConclusionNeuroradiologists should be aware that intimal flaps and multivessel dissections are more common after a traumatic etiology. In addition, it seems important to conduct a  CTA in a trauma setting, even if no cervical spine fracture is detected.
