Case Reports[Spontaneous cervical emphysema and pneumomediastinum with voice disorders].
Spontaneous cervical emphysema and pneumomediastinum, occurring in the absence of previous disorders or provocating factors, is very rare. The predominant symptoms are retroesternal pain, dyspnea, dysphagia and neck pain. ⋯ The evolution is generally good and conservative therapy leads to recovery in most patients. We present an unusual case of pneumomediastinum, cervical and retropharyngeal emphysema that spread to cavum; the suspected symptom was voice alteration as reported by the parents.
