INTRODUCTION Subcutaneous emphysema with pneumomediastinum is a rare phenomenon with a high morbidity and may occur spontaneously. CASE PRESENTATION A 30-year-old Caucasian man presented with sudden onset of a painful, swollen neck and was found, via clinical and radiological examination to have subcutaneous emphysema. A swallow study showed no oesophageal perforation. Computed tomography of ...

introduction:spontaneous pneumomediastinum, pneumothorax, and subcutaneous emphysema are rare, but serious complications of inflammatory myopathies and occur more commonly in dm than pm. complications of dermatomyositis (dm) and polymyositis (pm), both of which can be fatal. case report:a 20-year-old woman was admitted with neck pain, dyspnea, cough, and fever. she had been diagnosed with derma...

endoscopic retrograde cholangiopancreatography (ercp) is widely used for the diagnosis and treatment of biliary and pancreatic tract disease. perforation is a rare complication of it, but it is associated with high rate of mortality, an overall mortality rate of 1.0-1.5%. here, a case of massive subcutaneous emphysema following ercp was reported without an obvious retroperitoneal or peritoneal ...

Several complications can be related to surgical approaches of head and neck regions. Among those, there are rare conditions such as pneumomediastinum, pneumothorax and subcutaneous cervical emphysema. This study reports a case of a patient that developed pneumomediastinum, pneumothorax and subcutaneous emphysema after undergoing tonsillectomy. In order to reduce these complications in surgical...

Hamman (1939) first described postpartum pneumomediastinum in association with subcutaneous emphysema. This condition, also referred to as Hamman’s syndrome, is rare, with only about 200 cases reported worldwide [1], with an estimated incidence of 1 in 100,000 vaginal deliveries [2]. Despite its daunting presentation, the condition is usually minimal and the course is self-limiting [1]. Subcuta...

Introduction: Pneumomediastinum is an infrequent and rare pathology. The typical radiological manifestations in patients with SARS-CoV-2 pneumonia consist of the presence bilateral pulmonary opacities, peripheral distribution. In a recent series COVID-19, it indicates that 1% can develop spontaneous pneumomediastinum as complication, generally benign not yet clear this may be indicator wor...

Abstract Background Spontaneous pneumomediastinum, pneumothorax and spontaneous subcutaneous emphysema are rare entities. A rising trend in the setting of COVID-19 even patients who not put on invasive ventilation can suggest an alternative aetiology. Case presentation We describe four cases which presented with suspected symptoms were diagnosed pneumothorax, would have been missed if for compu...

Introduction Pneumomediastinum is defined as the presence of air or other gas in the mediastinum. This can be categorized as spontaneous or traumatic. Traumatic pneumomediastinum is caused by blunt or penetrating trauma to the chest or iatrogenic injury. Mediastinal air commonly originates from pneumothoraces (4,8). Pneumomediastinum in the absence of pneumothorax is frequently omitted in the d...

BACKGROUND Pulmonary infections caused by Pneumocystis jirovecii in immunocompromised host can be associated with cysts, pneumatoceles and air leaks that can progress to pneumomediastinum and pneumothoraxes. In such cases, it can be challenging to maintain adequate gas exchange by conventional mechanical ventilation and at the same time prevent further ventilator-induced lung injury. We report ...
