Multiple endocrine neoplasia (MEN) type 2B is a rare hereditary disorder characterized by medullary thyroid carcinoma, pheochromocytoma, and neuroma. Early signs of MEN 2B are usually neuroma, gastrointestinal problems, and medullary thyroid carcinoma. Noncardiogenic pulmonary edema is rare as a presenting symptom. We report a 31-year-old male who was admitted to our hospital because of noncardiogenic pulmonary edema. He was 168 cm in height, weighed 55 kg, and had an arm span of 166 cm. No marfanoid habitus was evident, but thickened lips and tongue neuroma were present. Chronic constipation had been present since childhood, and the patient had a two-year history of untreated hypertension. Noncardiogenic pulmonary edema and toxic megacolon were noted, and abdominal computed tomography revealed bilateral adrenal tumors. Ultrasonography of the thyroid showed two mass lesions. Intubation and mechanical ventilation were performed because of severe hypoxemia. Endocrinological examinations showed high levels of serum and urinary fractionated catecholamines, serum calcitonin, serum carcinoembryonic antigen, and serum intact parathyroid hormone. It was suggested that the high level of catecholamine from pheochromocytoma had caused the pulmonary edema. RET gene analysis showed a codon 918 mutation in exon 16 resulting in an ATG (methionine) to ACG (threonine) substitution, but analysis of the patient's parents showed the wild type. Therefore, the patient was diagnosed as having de novo MEN 2B. He underwent laparoscopic bilateral adrenectomy and total thyroidectomy. However, the values of serum calcitonin and CEA did not decrease to the normal ranges. Patients with early-stage MEN 2B have distinct characteristics that can aid early detection of the disease, thus possibly allowing them to be saved.

Vascular tortuosity syndrome is a rare genetic disorder that causes tortuosity and stenosis of the pulmonary, systemic and / or coronary circulations. As a result of treatment of pulmonary stenosis, symptoms of pulmonary edema, known as lung reperfusion syndrome, may occur. The case is presented of an adolescent patient with vascular tortuosity syndrome who presented with a pulmonary reperfusion syndrome after multiple stent implants in the left pulmonary artery. After the procedure, the patient immediately developed an acute pulmonary edema with severe clinical deterioration, which required assistance with extracorporeal membrane oxygenation for recovery.

Hypertrophic obstructive cardiomyopathy (HOCM) is a genetic condition most commonly characterized by hypertrophy of the ventricular septum, which leads to left ventricle outflow obstruction. Due to the severity of the condition, it is often diagnosed in adolescents, especially in those who exercise. We describe the case of a 53-year-old male, previously undiagnosed with hypertrophic cardiomyopathy (HCM), who became dyspneic during a bike race. He was found to have elevated troponin, pulmonary edema, and was diagnosed with HOCM. The late presentation of the case, in an active individual, makes the situation unique.

Congenital heart disease-associated pulmonary arterial hypertension (CHD-PAH) is one of the major complications in patients with CHD. A timely closure of the left-to-right shunt will generally result in the normalization of the pulmonary hemodynamics, but a few patients have severe prognosis in their early childhood. We hypothesized that wide-ranging pathological mechanism in PAH could elucidate the clinical state of severe CHD-PAH. Using electronic medical records, we retrospectively analyzed six infants with severe CHD-PAH who had treatment-resistant PH. All patients were born with congenital malformation syndrome. After starting on a pulmonary vasodilator, five of the six patients developed complications including pulmonary edema and interstitial lung disease (ILD), and four patients had alveolar hemorrhage. After steroid therapy, the clinical condition improved in four patients, but two patients died. The autopsy findings in one of the deceased patients indicated the presence of recurrent alveolar hemorrhage, pulmonary venous hypertension, ILD, and PAH. Based on the clinical course of these CHD-PAH in patients and the literature, CHD-PAH can occur with pulmonary vascular obstructive disease (PVOD)/pulmonary capillary hemangiomatosis (PCH), ILD, and/or alveolar hemorrhage. The severity of CHD-PAH may depend on a genetic disorder, respiratory infection, and upper airway stenosis. Additionally, pulmonary vasodilators may be involved in the development of PVOD/PCH and ILD. When patients with CHD-PAH show unexpected deterioration, clinicians should consider complications associated with PVOD/PCH and/or pulmonary disease. In addition, the choice of upfront combination therapy for pediatric patients with CHD-PAH should be selected carefully.
