Spontaneous Pneumomediastinum (SPM) is a very rare condition with an incidence of 1/30.000 and 1/44.500, and mostly seen in young men. The present article reports a case of SPM with neck swelling in the Emergency Department (ED). A 24-year-old male patient with fever and swelling on both sides of his neck presented at the ED. Physical examination revealed swelling on both parotid glands, neck and facial area. The pulmonary examination revealed a swelling starting from the upper side of the chest and extending toward the neck region and palpation revealed crepitation from the upper wall of the chest to both temporal fossae. Linear air radiolucency was seen in the posteroanterior chest x-ray. A Cervico-Thoracic CT scan revealed "showed" diffuse bilateral and symmetrical emphysema. SPM was diagnosed. He was admitted to the Thoracic Surgery Department for treatment and followup. Emergency physicians should consider SPM in the differential diagnosis of patients presenting with neck swelling. It should not be forgotten that close patient follow-up is required due to the possibility of severe complications.

“… 3 According to these authors, centripetal alveolar air infiltration along the connective tissue sheath surrounding the great vessels and bronchi into the mediastinal space would occur upon rupture of the marginal alveoli due to a sudden increase in intrathoracic pressure (ie, Valsalva maneuver or mechanical ventilation). Air infiltration may reach more distant anatomical sites, causing periorbital emphysema 4 or epidural pneumatosis. 5 SPM may occasionally be associated with pneumothorax.…”

Spontaneous pneumomediastinum (SPM) is the presence of air in the mediastinal interstices in the absence of any surgical or medical procedure, chest trauma, or mechanical ventilation. SPM can occur during vigorous Valsalva maneuvers, such as weight lifting, coughing fits, hyperemesis gravidarum, and so on, or during inhalation of illicit substances or toxic agents, as a result of an abrupt increase in pressure in the tracheal tree. Preexisting underlying lung disease may be a contributing factor. In the present case, we report for the first time an SPM due to accidental overexposure to paint thinner in a 15-year-old male from a low-income rural family. He was offered a job painting the inside of a house, which he accepted to earn some money for the family household. However, due to his inexperience, he overdosed on a can of paint with thinner. About 2 h after starting work, he began to feel increasingly severe chest pain and had to be rushed to the local level one basic hospital by his parents. Physical examination revealed subcutaneous emphysema over the supraclavicular area and crackles in the precordial area. Chest radiographs showed a pneumomediastinum. In retrospect, the patient denied coughing or sneezing attacks after exposure. He was transferred to a regional tertiary hospital for further diagnostic evaluation to rule out airway/esophageal perforation. Chest computed tomography confirmed underlying SPM and subcutaneous emphysema. The oesophagogram and bronchoscopy were unremarkable. SPM, possibly secondary to overexposure to thinner vapors, a hydrocarbon-based compound, was the final diagnosis. The patient was discharged asymptomatic on day 5.
