title: Pneumomediastinum during spontaneous vaginal delivery.
abstract: We report two rare cases of spontaneous pneumomediastinum that presented shortly after childbirth and resolved without treatment. Spontaneous pneumomediastinum has been described in a wide range of seemingly unrelated but recurrent clinical scenarios. We highlight their common etiologic factors and provide the anatomic and physiologic bases for the radiologic signs that are common in all these conditions.
