Spontaneous pneumomediastinum in a healthy young female: A case report and literature review

Abstract

Spontaneous pneumomediastinum (SPM) is an uncommon finding in young adults presenting usually without any comorbidities or an underlying pathology. It is most commonly due to alveolar rupture in the setting of an inciting event such an underlying asthma, barotrauma, valsalva maneuver, or esophageal rupture. Individuals can have varying presentations, from chest pain, dyspnea and dysphagia, to anxiety, weakness, or facial and neck swelling. The majority of patients have subcutaneous emphysema on examination and can have abnormal laboratory findings such as an elevated C-reactive proteins and leukocytosis. Diagnostic modalities used include chest x-ray, CT scan, ultrasound and barium swallow or esophagram. Majority of individuals and treated conservatively with rest, analgesia and oxygen administration. The prognosis of SPM is usually good with resolution within several days in most cases and the recurrence rate is very low. We report the case of a 22-year-old female presented with SPM diagnosed by chest x-ray and chest CT scan who was treated conservatively with subsequent spontaneous resolution.

Veterinary‐focused assessment with sonography for trauma‐airway, breathing, circulation, disability and exposure: a prospective observational study in 64 canine trauma patients

“…Similarly, US has also been used as an initial screening tool for the evaluation of pneumomediastinum in humans (Dirweesh et al . ). Although these conditions were not identified with US in the current study, they were not specifically evaluated during the VetFAST‐ABCDE protocol.…”

Case of chest pain in a young man

“…Predisposing factors include asthma, chronic bronchitis, respiratory tract infections, vomiting, choking and Valsalva manoeuvre including weightlifting 3. The most commonly reported symptoms include chest pain, neck pain, dyspnoea, dysphagia and swelling of the face and neck 4. Diagnosis can often be confirmed by posteroanterior and lateral chest radiography alone, but some authors recommend CT as the gold standard test 5.…”

“…Spontaneous pneumomediastinum is a rare benign condition, thought to be due to alveolar rupture, dissection of air along the bronchovascular spaces and escape of air into the mediastinum 1. It has been associated with asthma, interstitial lung disease, upper respiratory infection, drug abuse and smoking.…”
