Abstract

Objective: Describe two cases of spontaneous pneumomediastinum in the same service unit in young patients of different sex and that showed good progress with conservative treatment. Methods: The first case is a male patient, 18, with neck pain on the right side complaints and dysphonia for 2 days. Denied injuries or ingestion of strange bodies, heavy physical exertion, coughing and vomiting or drug use. CT of the chest and neck revealed the presence of bilateral anterior cervical subcutaneous emphysema, pneumomediastinum presence and absence of pneumothorax. The second case to be analyzed it is a female patient, 16 years old, complaining of sudden dyspnea and standard voice change (nasal). It was identified to fine crackling suggestive cervical palpation of subcutaneous emphysema. He denied any probable cause of secondary pneumomedistino. CT of the chest and neck revealed sharp pneumomediastinum extending to the deep neck spaces. Result: Both cases share of signs and symptoms previously described in the literature and had their diagnoses obtained by computed tomography. Symptomatic treatment associated with home was effective in both situations. Conclusions: Spontaneous pneumomediastinum may be underdiagnosed because of its nonspecific signs and symptoms, contributing to their unique character. It is important to establish the differential diagnoses and events to which patients were exposed. Accompanied a detailed history of radiological devices allow precise diagnosis and correct treatment.
