Medullary hemorrhage is quite rare among brain stem hemorrhage cases, thus the clinical course remains unclear. In the medulla oblongata, respiratory centers are located and previous reports indicate that medullary lesions have possible relationship with acute respiratory distress syndrome. This kind of respiratory failure is commonly caused by neurogenic pulmonary edema (NPE), which is defined as noncardiac noninfectious acute respiratory distress syndrome with changes in intracranial condition including cerebrovascular events. However, to date, very few reports have described cases with medullary hemorrhage accompanied by NPE. We experienced 2 patients with medullary hemorrhages. A 65-year-old man presented with sudden onset of headache, whose head computed tomography showed right medullary hemorrhage. Another 76-year-old woman was transferred because of sudden limb weakness and diagnosed with left medullary hemorrhage. Digital subtraction angiography showed the presence of arteriovenous fistula in the medulla oblongata and drainer veins in the second case. Both cases were complicated by acute pulmonary edema in the early phase, suggesting the possible association of the medullary hemorrhage with NPE.
