Question 1

Congenital disease of the epididymus

Answer 1

Spermatic granuloma of the epididymal head
Segmental aplasia (of mesonephric duct)

Question 2

causes of epididymitis

Answer 2

inflammation of the epididymis [from infection]
spermatic granuloma alone is not called epididymitis

Question 3

pathogenesis of spermatic granuloma of the epididymal head

Answer 3

Blind ended efferent ductules
>spermatostasis
>Spermatocele
>Spermatic granuloma
>Obstructs epididymal duct
>Infertility

=>XY Testicular DSD

Question 4

origins of segmental aplasia of mesonephric duct? what should we do?

Answer 4

XY Testicular DSD

Don’t use for breeding
* Hereditary
* No spermatozoal transport – Infertility
* Easily missed

Question 5

how does epididymitis arise in dogs; pathogenesis

Answer 5

Bacterial infection:
>Ascending - Gram negatives - E. coli
OR
>Hematogenous - Brucella canis

> Suppurative epididymitis with spermatic granulomas
99% of the time in tail of epididymid
majority ascending, often with cystitis

Question 6

clinical signs of epididymitis in dogs

Answer 6

pain,
systemic illness, self trauma

Question 7

how does epididymitis arise in rams; pathogenesis

Answer 7

Brucella ovis
>hematogenous dissemination
>localization and inflammation of tail of the epididymus
>spermatic granulomas

Gram negatives:
Histophilus somni OR Actinobacillus seminis
>ascending infection from prepuce
>inflammation of tail of the epididymis
>spermatic granulomas

Question 8

common spermatic cord diseases/findings:

Answer 8

Deferent duct:
Vasectomy

Pampiniform plexus:
Varicocele

Inguinal canal:
-Hernia * horse
-Lymph node – lymphoma

Question 9

disease of the accessory glands in bovines

Answer 9

Bovine vesicular adenitis

Question 10

Bovine vesicular adenitis pathogenesis

Answer 10

Young bulls
>Ascending infection:
-Trueperella pyogenes
OR
>Systemic infection:
-Mycoplasma
-Brucella abortus

> Acute fibrinopurulent or chronic interstitial inflammation
Infertility

Question 11

types of vesicular adenitis in bulls

Answer 11

-acute, supprative vesicular adenitis
-chronic vesicular adenitis with fibrosis and sequestrum

Question 12

diseases of the prostate in dogs

Answer 12

-Hyperplasia
-Inflammation
-Carcinoma (malignant)
-Cysts and abscesses

Question 13

how does the canine prostate enlarge with hyperplasia?

Answer 13

-prostate is testosterone dependent
-enlarges eccentrically with age

Question 14

most common cause of canine prostatitis, and some signs

Answer 14

E. coli
-fever, leukocytosis

Question 15

Prostate; paraprostatic cysts and abscess; how do most arise?

Answer 15

Most arise from cystic hyperplasia
-cysts can become infected, form abscesses

Question 16

in what dogs do we find carcinoma of the prostate? what are the possible results?

Answer 16

Older dogs
Local infiltration and metastasis.
>can cause obstructions, be space occupying

Question 17

types of carcinoma of the prostate in dogs?

Answer 17

Urothelial carcinoma
Adenocarcinoma
Carcinoma with mixed urothelial and glandular phenotypes
