Spontaneous delayed splenic rupture--case report of a five-year interval between trauma and diagnosis.

A 27-year-old white man was admitted in shock with a tender distended abdomen 5 years following significant thoraco-abdominal trauma. Immediately following resuscitation he had an emergency exploratory laparotomy because of his critical condition. At operation 3 liters of old and fresh blood were present intraperitoneally and the spleen was ruptured. The spleen was surrounded by and adherent to the omentum and adjacent viscera. Splenectomy was performed and recovery was uneventful. Histologic examination of the spleen confirmed the 5-year interval between injury and rupture. Delayed splenic rupture accounts for 14% of all splenic injuries and has a high mortality. This case represents the longest reported delay between splenic trauma and delayed rupture.
