Pneumothorax is a common complication in infants receiving assisted ventilation. The appropriate management of this condition is not always clearly defined, especially when a large air leak and mediastinal shift are present but the infant is hemodynamically stable. Despite the complications associated with chest tube placement, this remains the most common approach in such cases. We report 4 ca...

Air in the epidural space is called pneumorachis. The usual mechanism of pneumorachis is air diffusion from the mediastinal tissue layers through the inter-vertebral foramen. Alternatively, air can diffuse directly after spine traumas (e.g., blunt deceleration with vertebral dislocation) or medical procedures. Several mechanisms could explain pneumomediastinum and pneumorachis after cocaine sni...

Pneumoperitoneum in a preterm neonate usually indicates perforation of the intestine and is considered a surgical emergency. However, there are cases of pneumoperitoneum with no evidence of rupture of the intestine reported in the literature. We report a case of pneumoperitoneum with no intestinal perforation in a preterm neonate with respiratory distress syndrome who was on high frequency osci...

Idiopathic pneumomediastinum is rare in children. Few cases of patients with pneumomediastinum show negative findings on X-ray examination. Chest computed tomography (CT) was very useful for the diagnosis and evaluation of the extent of pneumomediastinum. We report here a case of idiopathic pneumomediastinum in a 15-year-old boy who exhibited no significant chest X-ray finding. The patient was ...

Background: Pneumomediastinum (PM) is caused by alveolar rapture. If air leak persists, subcutaneous emphysema occurs. The PM and subcutaneous emphysema have various etiologies. Common causes are respiratory tract infections and asthma exacerbations. Rarely, the PM occurs secondary to foreign body aspiration, and the life-threatening complications will occur without proper treatment. Case repo...

BACKGROUND Pneumomediastinum is commonly caused by iatrogenic injury such as surgery on the cervical planes and chest or by tracheostomy. It is also well known that emphysema may occur after dental treatments using an air turbine drill, but there have been few cases of emphysema which extended to the mediastinum. CASE PRESENTATION A 16-year-old boy is presented with subcutaneous emphysema and...

A previously healthy 37-year-old man with an upper airway viral infection presented with a progressive onset of neck pain with odinophagia and pretracheal tenderness after repetitive sneezing efforts. Upon examination, cervical subcutaneous emphysema was the only finding. The chest radiograph confirmed the presence of pneumomediastinum. Cervical and chest CT scans performed during a Valsalva ma...

An 11-year-old female presented to the emergency department with fever of 1 day’s duration and sore throat. Her family described a 3-week history of cough with fever, trouble breathing, and wheezing. Her medical history included panhypopituitarism and asthma, and she was receiving steroid replacement therapy. She had recently undergone a dental extraction. Examination showed a temperature of 39...

Pneumomediastinum is a condition in which air is present in the mediastinum. This condition can result from physical trauma or other situations that lead to air escaping from the lungs, airways or bowel into the chest cavity. Pneumomediastinum is a rare situation and occurs when air leaks into the mediastinum. The diagnosis can be confirmed via chest X-ray or CT scanning of the thorax. The main...

BACKGROUND Early identification of infants at higher risk of developing bronchopulmonary dysplasia (BPD) may enable a targeted approach to reduce BPD. We aimed to evaluate the hypothesis that the interstitial pneumonia pattern on the day 7 chest radiograph predicts BPD or death before 36 weeks postmenstrual age (PMA). METHODS A retrospective cohort study was performed on 336 preterm infants (...
