Traumatic pseudocyst of the spleen

Abstract

Four patients with pseudocyst of the spleen gave histories of abdominal trauma. In one patient the pseudocyst had ruptured, necessitating emergency splenectomy 34 years after the original injury. In a second patient the pseudocyst was discovered incidentally, and was managed by spleen-preserving excision; and the third and fourth presented with abdominal pain and had splenectomy and spleen-preserving surgery, respectively. All patients with conservatively treated splenic injury are at risk of developing a pseudocyst of the spleen, and the lesion can be detected by computed tomography or ultrasound. When there are no symptoms the natural history is unknown; but if surgery is necessary, splenectomy can sometimes be avoided.
