INTRODUCTION Subcutaneous emphysema or pneumomediastinum can occur as a complication of illicit drug use although this is rare. When occurring without a pneumothorax and spontaneously, it is usually treated conservatively, but can have serious consequences. CASE PRESENTATION Here, we present the case of an otherwise healthy 23-year-old Caucasian man who presented to the Emergency Department a...

BACKGROUND Patients with chronic hypersensitivity pneumonitis (HP) can present with an insidious onset of their disease without typical fluctuating flu-like symptoms, and there are only signs of chronic respiratory failure caused by the progressive fibrotic lung disease. CASE REPORT A 45-year-old man with a pneumomediastinum and interstitial lung disease was referred for further investigation...

We describe the case of an adolescent who was admitted to the hospital because of sudden occurrence of chest pain, dyspnea and subcutaneous emphysema. On admission, physical examination revealed subcutaneous crepitations in the superior part of the rib cage, and auscultation of the chest showed widespread wheezing. The radiological assessment confirmed the diagnosis of pneumomediastinum and pne...

BACKGROUND Spontaneous pneumomediastinum is an uncommon benign condition that is occasionally associated with subcutaneous emphysema and occasionally with pneumothorax, but is rarely associated with pneumorrhachis (air within the spinal epidural space). CASE REPORT We describe the case of a 20-year-old man and discuss a classification system of pneumorrhachis and its pathoanatomy, clinical an...

Objective. To present a rare case of extensive subcutaneous emphysema and spontaneous pneumomediastinum following ingestion of Ecstasy in a young adult. We also review the relevant literature and discuss how this case supplements it. Case Report. We report a case of a 19-year-old man with a history of painless neck and chest swelling, and no chest pain or breathlessness, after consuming Ecstasy...

Spontaneous pneumomediastinum is a relatively rare benign condition. It may rarely be associated with one or combination of pneumothorax, epidural pneumatosis, pneumopericardium, or subcutaneous emphysema. We present a unique case with four of the radiological findings in a 9-year-old male child who presented to our emergency department with his parents with complaints of unproductive cough, dy...

A 23-year-old male presented to the emergency department (ED) with sore throat, chest pain and shortness of breath that started two days prior to his arrival and gradually increased in severity. Other symptoms included pleuritic chest pain, back pain, dysphagia, odynophagia and general air hunger. The patient denied any history of trauma or similar symptoms. Spontaneous pneumomediastinum (SPM) ...

Spontaneous pneumomediastinum, or Hamman's syndrome, is a rare condition which may present with the symptoms of chest pain, dyspnoea, dysphagia, or neck pain. The signs of subcutaneous emphysema and Hamman's crunch (the presence of a crepitance sound that varies with the heartbeat on auscultation of the precordium) are usually present. A case of this syndrome occurring in an elderly patient wit...

Spontaneous pneumomediastinum following prolonged periods of severe coughing should raise the suspicion tracheal rupture in COVID-19 patients.

BACKGROUND Emphysematous cholecystitis is a variant of acute cholecystitis which is generally caused by gas-forming organisms. Emphysematous cholecystitis may cause gas spreading within the subcutaneous tissue, peritoneal cavity and retroperitoneum. CASE PRESENTATION We present a case of emphysematous cholecystitis in a middle-aged diabetic patient who, postoperatively, presented edema in bot...
