Spermatic cord leiomyosarcomas (LMSs) are rare tumors which may cause significant morbidity and mortality if inadequately diagnosed or treated. We report a case of a paratesticular LMS in a 60-year-old man who presented with a right scrotal mass. The patient was evaluated by scrotal ultrasound and computed tomography of the abdomen and pelvis (including scans of the scrotum), which revealed a large extratesticular mass. The lesion proved to be malignant and the patient underwent radical orchiectomy with high cord ligation. To improve the assignment of this lesion, we further analyze the imaging features of LMS and corre-late them with pathologic findings.
