One other pulmonary cause of sudden death should be mentioned. This is spontaneous pneumothorax of the newborn.67,68 This entity is relatively uncommon, occurring in 1-2% of live births, and is usually benign, with virtually all term infants having resolution without sequelae, often without the condition's being diagnosed. It should be suspected in any apparently healthy newborn who dies suddenly and unexpectedly in a hospital nursery. An X-ray prior to autopsy will make the diagnosis (Figure 3.16).
