Abstract

Primary spermatic cord leiomyosarcoma is a rare malignancy. We describe FDG PET/CT findings in a case of primary high-grade leiomyosarcoma of the spermatic cord. It appeared as a soft tissue mass with heterogeneous hyperenhancement on MRI and focal activity with SUV max of 4.8 on FDG PET/CT. This case indicates that spermatic cord leiomyosarcoma, although rare, should be included in the list of differential diagnoses of hypermetabolic spermatic cord lesions.
