Late-presenting diaphragmatic hernias, whether congenital or acquired, may
remain clinically undetected until mediastinal shift with cardiorespiratory
compromise or intestinal or gastric infarction with perforation occur. A r
ight-sided diaphragmatic hernia with herniation of small intestine into the
adjacent pleural cavity is described in a 72-year-old man who was found de
ad at home in a putrefactive state. Subsequently, a history of a motor vehi
cle accident 8 years previously was obtained. Although postmortem herniatio
n due to extensive putrefactive change may have occurred, producing gaseous
distention and migration of the intestine, tight twisting of the herniated
intestine several times around a pleural fibrous adhesion suggested that t
he herniation could have been an antemortem event. Unfortunately, marked ti
ssue autolysis prevented assessment of possible ischemic changes in the her
niated intestine. Although diaphragmatic hernia may be a contributing facto
r to death at all ages, it may not be possible to exclude it as an artifact
of putrefaction in a predisposed individual.
