wandering spleen
Wandering spleen (or Pelvic spleen) is a rare medical disease caused by the loss or weakening of the ligaments that help to hold the spleen stationary.
==Background==
Wandering spleen is most commonly diagnosed in young children as well as women between the ages of 20 and 40. Even so, the disease is very rare and fewer than 500 occurrences of the disease have been reported as of 2005,〔 of which around 148 (including both children and adult cases) were documented to have been from between 1960 and 1992. Less than 0.5% of all splenectomies, surgical removal of the spleen, are performed due to having this disorder.
Characteristics of the disorder include the loss, weakening, or malformation of the ligaments〔(【引用サイトリンク】 publisher=NORD )〕 that help to keep the spleen located in the upper left part of the abdomen. Though not a genetic disease, wandering spleen is often found at birth. It can occur in adults as the result of injuries and other similar conditions that cause the ligaments to weaken, such as connective tissue disease or pregnancy.〔
In 1992, the youngest case of the literature of torsion of wandering spleen at two days of birth was reported in Lebanon, by Dr Edouard Sayad.
