In Solution to Practice Question 6, the last sentence should read "Option E is the best response."

The text under Solution to Practice Question 8 should read:

Seminoma is the most common type of testicular tumor. They are usually well-circumscribed, hypoechoic lesions containing low-level echoes, but not calcifications. Option A is not the best response. Lymphoma typically presents as either focal or more diffuse hypoechoic regions with increased Doppler flow and occasional involvement of the adjacent epididymis. Option B is not the best response. Alternating bands of increased and decreased echogenicity, the so-called onion-ring appearance, is characteristic of an epidermoid cyst; however, the sonographic appearance is variable [12]. Epidermoid cysts with a target appearance, a sharply defined mass with a rim of calcium, and a solid mass with an echogenic rim, as in this patient, have been described [13]. Option C is the best response. Adenomatoid tumors are mixed-echogenicity tumors of the epididymis. Option D is not the best response. Lipomas typically arise in the spermatic cord. Option E is not the best response.

In Solution to Practice Question 9, the text beginning with "Supernumerary testes..." should read "Supernumerary testes are rare, usually presenting as a painless scrotal mass. Twenty percent of supernumerary testes are inguinal. Option C is not the best response."

We regret these errors.
