title: Traumatic para-mediastinal air cyst. A case report.
abstract: The roentgenographic features of a paramediastinal air cyst following chest trauma are reported. After an initial period of enlargement the lesion completely resolved in one month. Experience with this patient and a review of similar cases reported in the literature suggests that lesions of this type may be observed for spontaneous resolution.
