Q

What are 4 key characteristics of a scrotal mass that will let you narrow your differential?

3
Q

What would you suspect if the scrotal mass is separate from the testis, fluctuant and transilluminable?

A

Epididymal cyst

4
Q

What would you suspect if the scrotal mass is separate from the testis, non transilluminable and tender?

A

Acute epididymitis

5
Q

What would you suspect if the scrotal mass is not separate from the testis and is transilluminable?

A

Hydrocele (collection of fluid in tunica vaginalis)

6
Q

What would you suspect if the scrotal mass is not separate from the testis, not transilluminable and tender/ not tender?

A

Tender: Torsion, orchitis, epididymo-orchitis

Non tender: cancer

7
Q

What is indicated by an acutely swollen and tender scrotum that has been present for a matter of hours?

A

Testicular torsion until proven otherwise

8
Q

What is suggested by a feeling of heaviness in the testis?

Testicular cancer

9

A

TB epididymitis

12
Q

A

Para-aortal lymph nodes

13
Q

A

Inguinal lymph nodes

14
Q

Which tumour markers are commonly expressed in teratomas?

A

Varicocele

Q

Why is radical orchidectomy performed via an inguinal incision rather than a scrotal incision?

Scrotal incision would risk seeding malignant cells into the scrotum (separate lymph drainage)

A

Teratomas: 20-30y
Seminomas: 30-50y

19
Q

A

Left

left gonadal vein drains into left renal vein at 90 degree angle

20
Q

What can cause sudden appearance of a left sided varicocele?

A

Renal tumours (block left renal vein, impair gonadal drainage)

21
Q
