Neurogenic pulmonary edema induced by primary medullary hemorrhage: a case report.

摘要

We report a case of neurogenic pulmonary edema occurring in association with primary medullary hemorrhage. A pervious healthy 28-year-old man suddenly developed severe dyspnea without cardiac failure. Radiographs and computed tomography of the chest showed pulmonary edema. A diagnosis of primary medullary hemorrhage was made some weeks later by cranial magnetic resonance imaging showing an area of low signal intensity in both T1- and T2-weighted images in the right ventrolateral, medial, and dorsal medulla, extending from low to mid levels. We suspect that edema surrounding the lesion had superimposed an element of left dorsal medullary dysfunction and that bilateral dorsal medullary involvement had induced neurogenic pulmonary edema.
