Persistent hypoxemia and platypnea-orthodeoxia after left single-lung transplantation: a case report.

Introduction: Platypnea-orthodeoxia is a relatively uncommon but striking clinical syndrome characterized by dyspnea and deoxygenation accompanying a change to sitting or standing from a recumbent position. Hypoxemia early after lung transplant can have multiple etiologies. We report a rare case of persistent hypoxemia and platypnea-orthodeoxia after left single-lung transplantation, as a result of right-to-left interatrial shunt through a patent foramen ovale, with subsequent resolution of hypoxemia after percutaneous closure of the patent foramen ovale.

Encephalomalacic dysplastic mass lesion associated with vascular abnormalities in an elderly man. Is this "acquired" focal cortical dysplasia?

Focal cortical dysplasia (FCD) is known to occur in association with a principal lesion and has been newly introduced as FCD type III in the ILAE 2011 classification system of FCDs. FCD type IIIc is associated with vascular malformations, and in all such cases in the literature with histologic confirmation, the principal lesion was a cavernous angioma. We present here a case of mass-forming FCD type IIIc with very unusual vasculopathies.
