A Case of Sclerosing Angiomatoid Nodular Transformation of the Spleen: Spoke Wheel Pattern on Computed Tomography

Sclerosing angiomatoid nodular transformation (SANT) is a rare, benign vascular neoplasm. Most patients have no clinical symptoms, and the tumors are usually discovered incidentally on abdominal computed tomography or ultrasonography. Some studies have reported the clinical features and imaging findings of SANT, but the diagnosis is based on histopathologic examination of a tissue specimen obtained at splenectomy. We report herein an incidentally discovered case of SANT and review the related literature. (Korean J Med 2014;86:357-361)
