What is the sudden pain in the spleen?

Sudden splenic pain is commonly associated with traumatic splenic rupture and, rarely, splenic abscess. The most common cause of splenic pain is splenic rupture following a closed abdominal injury, which includes true rupture and pseudorupture. A true rupture is an interruption of the splenic envelope and is characterized by intra-abdominal hemorrhage and usually requires emergency splenectomy to cure. Pseudorupture is usually a subperitoneal hematoma without free abdominal bleeding and can be treated conservatively, but most patients may have a true rupture due to an enlarged pseudoruptured subperitoneal hematoma one to two weeks after the trauma, leading to the possibility of a repeat splenectomy. The exact cause of splenic abscess is not known; the main cause is the formation of bacterial infection into the spleen, which usually requires splenectomy.
