What are the FDG PET/CT and MRI findings in primary leiomyosarcoma of the spermatic cord?
Spermatic cord leiomyosarcoma should be included in the differential diagnosis of hypermetabolic spermatic cord lesions on FDG PET/CT.
Consider spermatic cord leiomyosarcoma in hypermetabolic cord lesions on FDG PET/CT; leaves open broader validation in prospective imaging studies.
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 SUVmax 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.

Man et al. (2026) conducted a case report in Primary leiomyosarcoma of the spermatic cord (n=1). FDG PET/CT was evaluated on FDG PET/CT findings (SUVmax). FDG PET/CT of a primary high-grade leiomyosarcoma of the spermatic cord demonstrated focal activity with an SUVmax of 4.8.
