Question 1

Most common primary testicular neoplasm in a 20-year-old male

Answer 1

Seminoma

Question 2

True about non-seminomatous tumors of the testis:
a. Less aggressive than than seminomatous
b. Most common of these are of mixed cell type
c. Less sensitive to radiation therapy
d. Consists of sheets of uniform cells with fibrous strands
e. Homogenous and hypoechoic on ultrasound

Answer 2

B. Most common of these are of mixed cell type

All others are characteristics of seminomatous GCT

Question 3

Main venous drainage of the epididymis and scrotal wall

Answer 3

Cremasteric plexus

Question 4

The left gonadal vein drains directly into ______

Answer 4

Left renal vein

Question 5

True about testicular neoplasm:
a. Hematogeneous spread is early in choriocarcinoma of the testis
b. Lymphatic spread is the least common type of tumoral spread
c. MRI performed for indeterminate lesions on ultrasound will reliably differentiate benign from malignant tumors
d. The inguinal nodes are involved early in the disease
e. Lymphatic spread initially follows the course of the internal iliac veins to the inferior vena cava

Answer 5

a. Hematogeneous spread is early in choriocarcinoma of the testis

a. True. Hematogenous spread to the lungs usually follows lymphatic spread, except with choriocarcinoma, which spreads hematogenously early
b. MOST common (gonadal lymphatic vessels > testicular veins > renal hilar nodes)
c. Neither US nor MR can reliably differentiate benign from malignant testicular tumors.
d. The internal iliac and inguinal nodes are RARELY involved.
e. Lymphatic metastases may also follow the external iliac chain to the para- aortic nodes.

Question 6

The most common cancer that is associated with urethral strictures is

Answer 6

Squamous cell carcinoma

Carcinoma of the urethra occurs as a complication of chronic urethritis and stricture. Carcinomas may appear as a filling defect in the urethra or as a change in appearance of the stricture. Most are squamous cell carcinomas and most involve the anterior urethra. MR is the imaging method of choice for showing extent of tumor (Fig. 48.33). Rare tumors of the posterior urethra are usually TCC that occur as part of multiple uroepithelial neoplasia.

Question 7

True of the
