Contrast-Enhanced Ultrasound and Real-Time Elastography for the Diagnosis of Benign Leydig Cell Tumors of the Testis – A Single Center Report on 13 Cases

Abstract

Contrary to some earlier reports, we could demonstrate marked hypervascularization in LCTs. This feature clearly allows for the differentiation of a small LCT from focal scars. However, it may only be visible on CEUS. In CEUS, LCT is suggested by the findings of a short filling time or by a circumferential vessel with a rapid centripetal filling, combined with a "harder" appearance in RTE. These features along with the findings of a small and peripherally situated hypoechoic tumor would justify an operative strategy with frozen section examination and possibly organ sparing surgery instead of orchiectomy.
