Volume 8, Supplement 1Review ArticlesContrast-Enhanced Ultrasound Imaging of Prostate CancerProstate Cancer ImagingEthan J HalpernUltrasound imaging of the prostate is commonly used to assess the size of the gland and for needle placement during systematic biopsy. Ultrasound evaluation of prostate cancer is limited by difficulty in distinguishing benign from malignant tissue. Although Doppler techniques may provide some improvement in the detection of prostate cancer, targeted biopsy based on conventional ultrasound with Doppler is not sufficient to replace systematic biopsy. Contrast-enhanced ultrasound imaging techniques that employ microbubble contrast agents represent an innovative approach to imaging of the neovascularity associated with prostate cancer. This review describes the application of contrast-enhanced ultrasound to improve detection and assessment of prostate cancer.

Volume 16, Number 4Case ReviewIntratesticular Epidermoid Cyst Masquerading as Testicular TorsionKevin M SlawinJeremy SlawinEpidermoid cysts are benign tumors that comprise approximately 1% of all testicular masses. They usually present as painless masses that can be identified on scrotal ultrasound as well-demarcated intratesticular lesions with mixed echogenicity. This case report describes a rare presentation of an extremely large intratesticular epidermoid cyst with clinical and radiologic findings more consistent with testicular torsion. The sizeable cyst obliterated the surrounding testicular parenchyma, causing it to appear on scrotal Doppler ultrasound as a testicle devoid of blood flow. This obliteration also resulted in failure to identify a testicular mass on physical examination or imaging. The current literature contains previous reports of extratesticular epidermoid cysts presenting as torsion; however, this is the first report of an intratesticular epidermoid cyst presenting in this manner. Though smaller cysts may be managed effectively with testicular-sparing surgery, optimal management of a cyst this size requires orchiectomy.
