Wandering spleen—the challenge of ultrasound diagnosis: Report of 7 cases

PURPOSE: To summarize our experience with sonographic diagnosis of wandering spleen in children and assess for the typical sonographic findings of wandering spleen, complications, and possible diagnostic pitfalls. METHODS: We identified all pediatric patients from 1998-2003 with a surgically confirmed diagnosis of wandering spleen. All sonographic examinations were reviewed for splenic position, size, echotexture, and parenchymal blood flow. RESULTS: Seven children were identified with a mean age of 9.7 years (range 4.2-15.3 years). All presented with abdominal pain. Abdominal sonography, performed in all children demonstrated a low position of the spleen (n = 6), splenomegaly (n = 4), and absence of parenchymal flow in the three patients with splenic torsion and infarction. The diagnosis was made preoperatively via sonography in five children; three required repeated hospital admissions before the correct diagnosis was established. Complications occurred in five patients (gastric obstruction n = 1, splenic infarction n = 3, and recurrent pancreatitis n = 1). CONCLUSION: The most specific sonographic finding for wandering spleen is low position of the spleen. However, if the spleen regains its normal or near-normal position, the diagnosis may be missed and the condition may recur, and result in complications.
