42
Q

rare stromal (non germ cell) tsticular tumor occuring in boys 5 - 10 yrs and men 30 - 60 yrs

A

leydig cell tumors

can also be mixed

always benign in children but can be malignant in adults

can also be in ovaries and usually malignant

43
Q

leydig cell tumors produse

A

testosterone resulting in presosious puberty

may also produce estrogen resluting in feminizing symtpons

44
Q

elevated alpha fetoprotein is not found in

A

seminomas

45
Q

levels of high serum tumor markers indicate

A

poor prognosis

46
Q

two types of benign testicular cysts

A

cysts of the tunica albuginea

intratesticular cysts

47
Q

intratesticular cysts are normally located near the

A

mediastinum testis and probably originate from the rete testis

48
Q

benign tumor of germ cell origin. well circumscribed solid tumors lying beneath the tunica albuginea. Filled with a cheesy white keratin. Appearas as a solid, hypoechic mass with an echogenic capsule or onion ring pattern formed by multiple layers of heratin

A

epidermoid cysts

bow tie, central echogenic pattern

49
Q

usually a complication of epididymo orchitis

appears with an enlarged testicle containing a predominantly fluid filled mass with hypoechic or mixed echogenic areas

A

testicular abscess

50
Q

called scrotal pearls and may be located within or between the layers of the tunica vaginalis

A

scrotal calcifications

microlithiasis

we don’t know much about these and follow up exams will be ordered

51
Q

uncommon event typically with an udetermined cause

typically present as a triangular shaped avascular intratesticular lesion

A

testicular infarct

52
Q

appearance of testicular infarct

A

depends on age of infacrtion

initially produces a focal or diffuse hypoechoic testicle

with time the testicle decreases in size and develops areas of increased echogenicity representing fibrosis or calcifications

53
Q

a serous fluid that accumulates within the tunica vaginalis or between the layers of the tunica vaginalis (visceral and parietal layers)

is standing

with valsalva

ABD pressure

torsion

epididymitis

varicocele thrombosis

result from bowel protruding through the inguinal canal into the tunica vaginalis of the scrotum

A

scrotal hernia

peristalsis confirms (bowel movement)

small inguinal hernia can be seen by using valsalva

64
Q

extratesticular tumors usually involve

A

the epididymis

65
Q

most common extratesticular tumor

A

adenomatoid tumor

66
Q

cystic masses of the epididymis that result from dilatation of the epididymal tubules

A

spermatoceles (composed of milky fluid containing spermatozoa)

epididymal cysts (composed of clear fluid)

both are a result of epididymitis

67
Q

spermatoceles are ____ common than epididymal cysts

A

more

68
Q

spermatoceles usually are at the

A

epididimal head

69
