Bronchopulmonary sequestration represents a spectrum of abnormalities. One of these abnormalities is an aberrant systemic arterial supply to a normal lung with no bronchial sequestration. These lesions were originally classified by Pryce as type 1. Most of these patients are asymptomatic but with time, many patients develop localized pulmonary hypertension, hemoptysis, and eventually high output cardiac failure. Multidetector computed tomography (MDCT) plays an important role in the diagnosis and planning of definitive treatment by identifying the origin and course of the aberrant artery. Definitive treatment can be surgical (lobectomy or segmentectomy) or endovascular.

We report a rare presentation of mitral stenosis (MS). MS is a common valvular disease, the first manifestation of which is usually easy fatigability and exertional dyspnea. As the disease progresses in severity, other signs and symptoms appear, such as orthopnea, hemoptysis, and peripheral edema. This is the first report of a case of mitral stenosis presenting with exertional abdominal pain as the first manifestation. This case report describes the clinical characteristics of a 55-year-old woman with mitral stenosis and severe pulmonary hypertension, whose first symptom was exertional abdominal pain.

Because most medications for pediatric pulmonary hypertension (PH) are used off label and based on adult trials, little information is available on pediatric-specific adverse events (AEs). Although drug manufacturers are required to submit postmarket AE reports to the Food and Drug Administration (FDA), this information is rarely transmitted to practitioners. In the setting of a recent FDA warning for sildenafil, the authors sought to give a better description of the AEs associated with current therapies in pediatric PH. In January 2010, a written request was made to the Food and Drug Administration for AE records of commonly used PH medications. Reports were screened for pediatric patients, analyzed in terms of AEs, and compared with the medical literature. Arbitrarily, AEs that could be attributed to concomitant medications were not attributed to the PH medication in question. Adverse events occurring in more than 5 % of events for each drug were assumed to be associated with the targeted PH medication. Between November 1997 and December 2009, 588 pediatric AE reports (death in 257 cases) were reported for the three most commonly used therapies: bosentan, epoprostenol, and sildenafil. Many of the AEs were similar to those reported previously. However, 27 AEs not previously reported in the literature (e.g., pulmonary hemorrhage, hemoptysis, and pneumonia) were found. The FDA postmarket records for PH medications in pediatric patients show a significant number of AEs. The discovery of AEs not previously reported will better inform those caring for these complex and critically ill children, and the large number of deaths suggest they may be underreported in current literature.

Sildenafil, usually a well-tolerated drug traditionally used for erectile dysfunction (ED), was recently approved for pulmonary arterial hypertension. In the literature, there are few cases of hemoptysis following sildenafil use for ED; however, to our knowledge, we are reporting the first case of hemoptysis following sildenafil use for pulmonary hypertension. We are documenting a case of a 90-year-old male patient who was admitted to the intensive care unit with hemoptysis and respiratory failure two weeks after he was started on sildenafil.

The patient was a 41-year-old female with chronic thromboembolism. She was admitted to an affiliated hospital with exertional dyspnea, leg swelling, and hemoptysis, and she was treated medically with tissue plasminogen activator and warfarin therapy. When transferred to our hospital, she was oxygen-dependent with severe dyspnea. A pulmonary arteriogram showed occlusion and stenosis of the pulmonary arteries. Cardiac catheterization revealed marked pulmonary hypertension. The lung perfusion scintigram showedmultiple defects in the right and left lungs. Preoperative laboratory data showed a markedly decreased protein C antigen level. Magnetic resonance angiography showed that a myoma uteri compressed the pelvic vein and that she had deep vein occlusion of the left leg. After the administration of an epoprostenol infusion and the insertion of an inferior vena cava filter, she underwent an operation. Under deep hypothermia, the bilateral pulmonary artery was opened and an endarterectomy was performed during intermittent circulatory arrest. After surgery, her pulmonary vascular resistance was in the normal range. Her New York Heart Association functional classification changed from class IV to class I. She has been in good condition for 7 years since the surgery.

Sarcoidosis is a systemic inflammatory disease with a predilection for the respiratory system. Although most patients enter remission and have good long-term outcomes, up to 20% develop fibrotic lung disease, whereby granulomatous inflammation evolves to pulmonary fibrosis. There are several radiographic patterns of pulmonary fibrosis in sarcoidosis; bronchial distortion is common, and other patterns, including honeycombing, are variably observed. The development of pulmonary fibrosis is associated with significant morbidity and can be fatal. Dyspnea, cough, and hypoxemia are frequent clinical manifestations. Pulmonary function testing often demonstrates restriction from parenchymal involvement, although airflow obstruction from airway-centric fibrosis is also recognized. Complications of fibrotic pulmonary sarcoidosis include pulmonary hypertension from capillary obliteration and chronic aspergillus disease, with hemoptysis a common and potentially life-threatening manifestation. Immunosuppression is not always indicated in end-stage sarcoidosis. Lung transplantation should be considered for patients with severe fibrotic pulmonary sarcoidosis, as mortality is high in these patients.

Catheter-induced pulmonary artery rupture is an infrequent complication that may occur during invasive cardiopulmonary monitoring. Fatal cases are uncommon and result from hemoptysis and flooding of the opposite lung with resulting hypoyxia. Alpha-1-antitrypsin deficiency is a rare genetic disorder characterised by low serum levels of alpha-1-antitrypsin, critical in maintaining connective tissue integrity. Besides pulmonary emphysema, recent observations suggest that alpha-1-antitrypsin deficiency may also be involved in vascular wall weakening, thereby predisposing arteries to dissection and aneurysm formation. In this article, we describe an autopsy case of pulmonary artery iatrogenic rupture due to insertion of a Swan-Ganz catheter in an 82-year-old woman suffering from pulmonary hypertension and alpha-1-antitrypsin deficiency. The exact source of bleeding could not be precisely identified during autopsy due to the extent of tissue hemorrhage, though postmortem angiography revealed a contrast medium extravasation from a branch of the left pulmonary lower lobar artery. The case herein emphasises the importance of postmortem angiography in facilitating the detection of vascular injuries, the importance of familiarity with intensive care techniques and procedures on behalf of forensic pathologists as well as in-depth knowledge of all possible contributing conditions and predisposing disorders in the pathogenesis of death.

Pulmonary manifestations of hyperthyroidism not only include pulmonary hypertension and hydrostatic pulmonary oedema, but also treatment/drug-associated pulmonary diseases have to be considered as an exclusion diagnosis. A 27-year-old woman with hypoxaemic respiratory failure under an arterial-venous extra-corporeal membrane oxygenator (AV-ECMO) was admitted to the intensive care unit (ICU). The patient had progressive dyspnoea with haemoptysis, palpitations and failure to thrive. The patient had Graves' disease treated previously with propylthiouracil (PTU). Diffuse alveolar haemorrhage is a non-specific syndrome characterised by evidence of diffuse alveolar damage, exclusion of infectious aetiology and progressively bloodier bronchoalveolar lavage (and/or 20% hemosiderin laden macrophages on cytological examination). PTU associated perinuclear antineutrophil cytoplasmic antibodies (p-ANCA) vasculitis appears to be more common in younger female patients presenting with leukocytoclastic vasculitis, myalgias and arthralgias. The latter compared to non-drug associated ANCA vasculitis which are more common in older males with visceral involvement. PTU-induced ANCA vasculitis prognosis appears to be better compared to primary ANCA syndromes.

Sarcoidosis has innumerable clinical manifestations, as the disease may affect every body organ. Furthermore, the severity of sarcoidosis involvement may range from an asymptomatic state to a life-threatening condition. This manuscript reviews a wide variety of common and less common clinical characteristics of sarcoidosis. These manifestations are presented organ by organ, although additional sections describe systemic and multiorgan presentations of sarcoidosis. The lung is the organ most commonly involved with sarcoidosis with at least 90 % of sarcoidosis patients demonstrating lung involvement in most series. The skin, eye, liver, and peripheral lymph node are the next most commonly clinically involved organs in most series, with the frequency of involvement ranging from 10 to 30 %. The actual frequency of sarcoidosis organ involvement is probably much higher as it is frequently asymptomatic and may avoid detection. This is particularly common with lung, liver, cardiac, and bone involvement. Cardiac sarcoidosis is present in 25 % of all sarcoidosis but only causes clinical problems in 5 % of them. Nevertheless, unlike sarcoidosis involvement of most other organs, it may be suddenly fatal. Therefore, it is important to screen for cardiac sarcoidosis in all sarcoidosis patients. All sarcoidosis patients should also be screened for eye involvement as asymptomatic patients may have eye involvement that may cause permanent vision impairment. Pulmonary fibrosis from sarcoidosis is usually slowly progressive but may be life-threatening because of the development of respiratory failure, pulmonary hypertension, or hemoptysis related to a mycetoma or bronchiectasis. Some manifestations of sarcoidosis are not organ-specific and probably are the result of a release of mediators from the sarcoid granuloma. Two such manifestations include small fiber neuropathy and fatigue syndromes, and they are observed in a large percentage of patients.

Pulmonary artery (PA) agenesis in the absence of associated cardiac abnormalities is a rare congenital abnormality. It may remain undiagnosed until adulthood when patients present with respiratory symptoms such as hemoptysis, dyspnea, repeated respiratory infections, or pulmonary hypertension. Herein we present a case of a 50-year-old woman who was found to have multiple, morphologically distinct non-small cell lung cancers in association with agenesis of the PA. This instance represents the fourth reported case of such association in the English literature.
