Description
Background Although intracranial hemorrhage and infarction have been reported in patients with H1N1 influenza infection treated with extracorporeal membrane oxygenation (ECMO), the clinical outcomes of these patients are not well described. Methods The authors present two patients with H1N1 influenza infection and diffuse cerebrovascular injury in the setting of ECMO. Results Diffuse cerebrovascular injury including intraparenchymal hemorrhage was found on head CT and brain MRI in both cases and confirmed by autopsy in one patient who died. Punctate foci of susceptibility effect were seen in both patients on T2* susceptibility-weighted or susceptibility- sensitive gradient echo sequences. These foci of susceptibility effect were consistent with infarction on histopathologic evaluation in the patient who died. The other patient made an excellent clinical recovery. Conclusions Frequent and early surveillance imaging should be obtained in patients with H1N1 influenza infection undergoing ECMO, although the presence of diffuse cerebral injury, including intraparenchymal hemorrhage and multifocal punctate susceptibility effect, does not necessarily portend a poor prognosis.
