title: A case of sclerosing angiomatoid nodular transformation:the correlation between imaging and pathological findings.
abstract: A 53-year-old woman was referred to our hospital with a 40-mm splenic tumor, which was detected incidentally on abdominal computed tomography during hospitalization for pyelonephritis. The tumor was hypointense on T2-weighted imaging and gradually enhanced on dynamic study. The tumor increased in size over a six-month period. Since we could not exclude splenic malignancy, we performed laparoscopic partial splenectomy. Histological examination revealed multiple angiomatoid nodules with three distinct vessel types. Pathologically, the tumor was diagnosed as a sclerosing angiomatoid nodular transformation (SANT). We then examined the correlation between the imaging and pathological findings, and performed a review of previous reports, concluding that contrast-enhanced MRI was the most useful modality for diagnosing SANT.
