Spontaneous pneumomediastinum and subcutaneous emphysema (Hamman's syndrome) are rare but potentially dangerous complications of labour. The authors reported a case of a 23-year-old primigravida, admitted to our hospital for delivery after 40 weeks of pregnancy. ⋯ A chest X-ray and CT scan revealed pneumomediastinum and subcutaneous emphysema. The patient had been followed up for 3 days in our hospital, without specific therapy.
