Hemangiosarcoma of the spleen: helical computed tomography features.

Hemangiosarcoma of the spleen is a rare malignant tumor. Prognosis is poor and is usually related to splenic rupture. Clinical symptoms include abdominal pain and left upper quadrant mass. Many clinical conditions have similar presenting symptoms and make diagnosis difficult. However, in this case report, we describe characteristic contrast enhancement pattern with spiral CT imaging of hemangiosarcoma of the spleen. Such imaging features with the previously described clinical symptoms will help in making the diagnosis early. Early splenectomy will improve prognosis and survival.
