The occurrence of neurogenic pulmonary edema (NPE) associated with subarachnoid hemorrhage (SAH) due to ruptured aneurysm was analyzed in 48 consecutive patients. Correlations of the location of the aneurysm, clinical grade, amount of subarachnoid clot, and severity of NPE were examined. NPE was observed in 29.4% of all SAH cases, but the incidence was significantly higher in cases of ruptured vertebral artery (VA) aneurysm. Clinical grade, severity of NPE, and deformation of the medulla oblongata were studied in the five cases of ruptured VA aneurysm. Deformation of the ventrolateral medulla oblongata was observed in all patients. Asymmetry index of the medulla oblongata measured on the axial computed tomography scan was correlated with the severity of NPE. Severity of NPE tended to correlate with deformation of the medulla oblongata. NPE associated with ruptured VA aneurysm is caused by deformation of the ventrolateral site of the medulla oblongata by the localized hemorrhage.
