A 34-year-old Japanese male was admitted to Okayama University Hospital with severe hypertension, rapidly progressive renal failure, blurred vision, dyspnea and hemoptysis. Clinical diagnosis of malignant hypertension was given and antihypertensive therapy and hemodialysis were immediately started. Renal biopsy was performed on the sixth day in hospital to examine the underlying disease, such as microscopic form of polyarteritis, since the complaint of hemoptysis and pulmonary alveolar hemorrhage was noted by computed tomography of the lungs. Typical pathological changes of malignant hypertension, i.e. fibrinoid necrosis of the afferent arterioles and proliferative endoarteritis at the interlobular arteries were observed. There was no evidence of active necrotizing glomerulonephritis and crescent formation. Renal function was gradually recovered and pulmonary hemorrhage completely disappeared by treatment with antihypertensive agents. The authors report a case of malignant hypertension with a rare complication of pulmonary alveolar hemorrhage and speculate that it may be related to vascular injuries at the alveolar capillary level caused by malignant hypertension.

A 34-year-old man presented with fever, weight loss, paresthesia, abdominal pain, and hypertension. He had hepatitis B antigenemia, with negative antineutrophil cytoplasmic antibody, antinuclear antibody, and antiglomerular basement membrane serology results. Renal arteriography showed multiple intrarenal microaneurysms. In spite of therapy with antiviral agents (lamivudine, famciclovir), prednisone, cyclophosphamide, and plasmapheresis, renal function deteriorated. He later developed rapidly progressive dyspnea and hemoptysis. Diffuse alveolar hemorrhage was confirmed by bronchoscopy. He died of respiratory failure. The cause of pulmonary hemorrhage in this case of polyarteritis nodosa is unclear, but may include underlying capillaritis, cocaine-induced pulmonary hemorrhage, or recurrent attacks of malignant hypertension.

A 27-year-old man presented at the emergency room with hemoptysis. His blood pressure was 180/100 mm Hg, and he had no history of hypertension. Chest radiographs showed bilateral infiltration, suggestive of alveolar hemorrhage. His laboratory data were consistent with acute kidney injury. His serum creatinine level increased abruptly; therefore, renal biopsy was performed. Steroid pulse therapy was administered because of a strong suspicion of immune-mediated pulmonary renal syndrome. Renal biopsy showed proliferative endarteritis, fibrinoid necrosis, and intraluminal thrombi in the vessels without crescent formation or necrotizing lesions. Steroid pulse therapy rapidly tapered and stopped. His serum creatinine level gradually decreased with strict blood pressure control. Ten months after discharge, his blood pressure was approximately 120/80 mm Hg with a serum creatinine level of 1.98 mg/dL. Pulmonary renal syndrome is generally caused by an immune-mediated mechanism. However, malignant hypertension accompanying renal insufficiency and heart dysfunction causing end-organ damage can create a pulmonary hemorrhage, similar to pulmonary renal syndrome caused by an immune-mediated mechanism. The present case shows that hypertension, a common disease, can possibly cause pulmonary renal syndrome, a rare condition.

A 43-year-old full-term pregnant woman (gravida 2, para 1, medical history of gestational diabetes mellitus) developed a sudden and malignant hypertension with hemoptysis, sweat, and tachycardia during a scheduled C-section. A dead newborn was delivered and was successfully resuscitated. The mother died after resistant cardiac arrest. Autopsy and pathological analyses revealed an acute pulmonary edema and a necrotic and hemorrhagic voluminous tumor of the left adrenal gland, which was a pheochromocytoma. Pheochromocytoma is a rare tumor of the adrenal glands which secretes catecholamines. In pregnant women, its symptoms can mimic gestational hypertension, preeclampsia or eclampsia, and gestational diabetes mellitus. The gestational diabetes mellitus was presumed to be a symptom of the pheochromocytoma, and cardiopulmonary failure the result from the necrosis of the tumor provoked by gravid uterus compression. From a medico-legal point of view, the tumor could not have been suspected during the pregnancy.

Diffuse alveolar hemorrhage is a clinicopathological syndrome that often leads to respiratory failure, with associated hemoptysis and anemia. Chest radiograph presents non-specific findings of perihilar infiltrates, while computed tomography shows ground-glass attenuation or areas of consolidation with interlobular septal thickening. Bronchoalveolar lavage is used to confirm the clinical and radiological suspicion. While vasculitis and other causes of pulmonary renal syndrome are the most common causes of diffuse alveolar hemorrhage, malignant hypertension should be considered in the proper clinical setting. We present a case report of a 51-year-old previously healthy patient that was diagnosed with diffuse alveolar hemorrhage and acute renal failure due to malignant hypertension, through clinical and radiological findings.
