Wandering spleen is a rare condition that occurs when the spleen lacks one or more of the ligments that hold the spleen in its normal position in the upper left abdomen. If a person is born with this condition it is referred to as congenital wandering spleen. The condition is not hereditary. Acquired wandering spleen may occur during adulthood due to injuries or other underlying conditions that may weaken the ligaments that hold the spleen. Symptoms of wandering spleen may include englargement of the spleen (splenomegaly), abdominal pain, intestinal obstruction, nausea, vomiting, fever, and a lump in the abdomen or the pelvis. Some individuals with this condition do not have symptoms. Treatment for this condition involes removal of the spleen (splenectomy).
