A case of a fullterm infant with severe neonatal respiratory distress due to mumps infection is reported. Pregnancy was complicated by a self-limited febrile illness of the mother about two weeks before birth. Foetal heart rate patterns and delivery were normal. Immediately after birth the infant needed mechanical ventilation. Bacterial infections, as well as congenital cardiac or pulmonary malformations were excluded. The infant showed serologic evidence of mumps infection: IgM antibodies to mumps virus were highly positive. He expired on the 9th day of life due to bilateral pneumothoraces and pneumopericardium. Post-mortem examination showed interstitial pneumonia with intra-alveolar multinucleated giant cells, suggesting viral disease. This case demonstrates, that mumps pneumonia should be included in the differential diagnosis of severe neonatal respiratory distress in fullterm neonates.

A 52-year-old man had been treated for oral cancer T3 N0 M0 by radical surgery, neck dissection on the right and cervical irradiation (60 Gy). Two months after therapy he presented with dysphagia and hemoptysis. Admission chest X-ray revealed a pneumopericardium. It was caused by a bronchomediastinal fistula due to necrotic metastatic lymph nodes as shown by CT, which also revealed a concomitant pneumomediastinum. The patient died 10 days later from pneumonia. The CT findings were confirmed at autopsy. We conclude that malignant mediastinal lymphadenopathy is a potential cause of pneumopericardium and pneumomediastinum.

Common complications of cardiac transplantation include infection, rejection, accelerated coronary artery atherosclerosis, and lymphoproliferative disease. The authors reviewed radiographic and computed tomographic (CT) features of cardiac transplantation and its complications in a series of 232 patients (with 89 complications and 49 deaths). Normal postoperative findings in the first few weeks after surgery included enlarged cardiac silhouette, pneumomediastinum, pneumothorax, pneumopericardium, subcutaneous emphysema, and mediastinal widening. Infection was the most common complication, with pneumonia being the leading infectious condition (28 cases, with Aspergillus [n = 11] and cytomegalovirus [n = 10] being the most common pathogens) and the cause of death in seven cases. Although many cases of pulmonary infections occur in the first 3-4 months after surgery, in this series several cases developed up to 3 years afterward. Radiographic signs of acute rejection were nonspecific in the eight patients affected who died, and endomyocardial biopsy was used to confirm the suspected diagnosis. Accelerated atherosclerosis occurred in 13 patients between 10 months and 6.5 years after transplantation and led to death in eight. Lymphoproliferative disorders, which range from benign lymphoid hyperplasia to malignant lymphoma and which are the third leading cause of death beyond the immediate perioperative period in heart transplant recipients, developed in four patients who later died. Other complications related to endomyocardial biopsy and cardiothoracic surgery (i.e., pneumothorax, hemothorax, pneumomediastinum, mediastinitis, aortic dissection, aortic pseudoaneurysm, and pulmonary embolism) occurred in 31 cases and were diagnosed with radiography and CT.

The authors describe a patient with spontaneous pneumopericardium complicating staphylococcal pneumonia and empyema that resulted in cardiac tamponade. Spontaneous pneumopericardium is an unusual disorder. The causes and clinical findings of pneumopericardium are reviewed, as are the radiographic features that differentiate this condition from pneumomediastinum. Early recognition of pneumopericardium is important, because emergent pericardiocentesis may be required if there is clinical evidence of tamponade.

A 22-year-old man was admitted with pneumonia. He was immediately intubated and positive pressure ventilation was initiated. Blood and sputum cultures showed Bacteroides fragilis and Corynebacterium sp., which were treated with metronidazole and clindamycin. Three weeks later his blood pressure suddenly dropped with an elevation of the central venous pressure. Chest X-ray revealed a pneumopericardium. A parasternal mediastinotomy with partial pericardiectomy was immediately performed. On opening the pericardium his blood pressure normalised. The patient gradually recovered and six weeks after admission he was extubated. Two weeks later he was discharged. A pneumopericardium without previous thorax trauma is very rare and early recognition is imperative because a tension pneumopericardium with cardiac tamponade may develop, as happened in this case. A tension pneumopericardium has to be treated with immediate pericardiocentesis followed by partial pericardiectomy to avoid recurrence.

Pneumopericardium is an uncommon but potentially serious condition. It appears in association with invasive diagnostic and therapeutic procedures, although cases have also been reported in association with bronchospasm, esophageal disorders, and other problems. We describe a case of spontaneous pneumopericardium with chest pain in a patient with community-acquired pneumonia.

Bronchiolitis obliterans (BO) or bronchiolitis obliterans organizing pneumonia (BOOP) is one of manifestations of graft-versus-host disease (GVHD), a complication of hematopoietic stem cell transplantation (HSCT). Recently there are reports about thoracic air-leakage syndrome (TALS), but real incidence, clinical course, and implications of TALS remain unclear. Retrospective review of 18 TALS patients among 2,177 patients who received allogeneic HSCT between January 2000 to July 2007 was done. Clinical manifestations, treatments, and outcomes of TALS were reviewed. The incidence of TALS was 0.83% (18/2,177). The onset of TALS was mean 425.9+/-417.8 days (60-1,825 days) after HSCT, and the duration was mean 16.3+/-21 days (2-90 days). The most common types of TALS were spontaneous pneumothroax (n=14), followed by subcutaneous emphysema (n=6), pneumomediastinum (n=5), interstitial emphysema (n=2), and pneumopericardium (n=1). TALS persisted in six patients, who died during the same hospitalization. The 12 patients recovered from TALS, but only 2 survived, while others died due to aggravation of GVHD. TALS may complicate BO/BOOP and be an initial manifestation of BO/BOOP. TALS is hard to be resolved, and even after the recovery, patients die because of aggravation of GVHD. We suggest specifically in HSCT patients, when once developed, TALS seems hard to be cured, and as a result, be related to high fatality.

Pneumopericardium is a rare complication of chest trauma, mechanical ventilation and cavitating pneumonia. We report a case of a 7-year-old patient with chronic myeloid leukemia who developed massive pneumopericardium immediately after being electively intubated for a diagnostic radiological procedure in the setting of ongoing Enterococcal pneumonia. As intensive care medicine becomes more prevalent in hospitals, we believe that clinicians need to be aware of this uncommon but potentially fatal condition.

Spontaneous pneumothorax occurs in up to 35% of patients with Pneumocystis jirovecii pneumonia. However, spontaneous pneumomediastinum and pneumopericardium are uncommon complications in patients infected with human immunodeficiency virus, with no reported incidence rates, even among patients with acquired immunodeficiency syndrome (AIDS) and P. jirovecii pneumonia. We report a case of spontaneous pneumomediastinum, pneumopericardium, and pneumothorax with respiratory failure during treatment of P. jirovecii pneumonia in a patient with AIDS; the P. jirovecii infection was confirmed by performing methenamine silver staining of bronchoalveolar lavage specimens. This case suggests that spontaneous pneumomediastinum and pneumopericardium should be considered in patients with AIDS and P. jirovecii pneumonia.

This report describes a case of severe spontaneous tension pneumopericardium with concurrent pneumomediastinum, pneumothorax and retropneumoperitoneum in a cat presenting with dyspnoea and signs of cardiac tamponade secondary to metastatic pulmonary carcinoma. Spontaneous pneumopericardium is an extremely uncommon condition consisting of pericardial gas in the absence of iatrogenic/traumatic causes. In humans, it has been described secondary to pneumonia or lung abscess and very rarely secondary to pulmonary neoplasia.
