Spermatic cord sarcomas: sonographic and CT features.

Five patients with sarcomas of the spermatic cord were imaged with sonography and/or computed tomography (CT). The former modality is most helpful in demonstrating the extratesticular origin of the mass and evaluating its scrotal extension for local staging. CT is necessary for pelvic staging and searching for distant metastasis. The fat in liposarcomas was easily identified by CT, although it was not echogenic on sonography. Sonography should be the primary imaging modality for scrotal or inguinal masses. If a neoplasm is found, CT should be used for staging, prior to definitive surgical treatment.
