does malignant degeneration occur in multilocular cystic nephroma
|
no, but can be difficult to differentiate from a cystic RCC so must be resected
|
|
causes of hydrosalpinx
|
infx
adhesions endometriosis ectopic pregnancy |
|

|
contrast may or may not fill the dilated tube
|
|
findings of pelvic floor descent
|
midline location of a descended bladder along with descent of uterus
|
|
why does the bladder not completely empty in pelvic floor descent
|
the bladder descends below the level of the urethral meatus -> recurrent infx, hydronephrosis
|
|
what is a urinary bladder hernia
|
when the bladder herniates through the usual hernial orifices
virtually never occurs in midline |
|
where does TCC of the ureter most commonly occur
|
distal 1/3 of the ureter
|
|
in trauma, mechanism of intraperitoneal bladder rupture
what part of the bladder is injured |
direct blow to a distended bladder
usually affects the bladder dome |
|
which type of bladder rupture is most common in setting of trauam
|
extraperitoneal bladder rupture
|
|
where does contrast go in intraperitoneal rupture
|
outlines loops of bowel
|
|
is space of retzius intra- or extra-peritoneal
|
extra
|
|
etiologies for hematocele
|
trauma
surgery neoplasm |
|
are septations seen in hematocele
|
yes
|
|
next step if a complex hydrocele is seen
|
evaluate for a mass
|
|
appearance of a uterine lipoleimyoma
|
fat containing mass within the uterus, usually surrounded by myometrium
most often arise from the fundus |
|
fat containing lesions of the uterus
|
lipoleiomyoma
angiomyolipoma fibrolipoma fat containing sarcomas |
|
who gets lipoleiomyomas
|
women 50-70 yo
|
|
#1 uterine neoplasm
|
leiomyoma
|
|
where are subserosal fibroids located
|
near the SURFACE
|
|
whorled appearance in a uterine mass is characteristic of what
|
leiomyoma
|
|
best sequence to assess fibroids
|
T2
|
|
what is the CT protocol to assess for adrenal lesions
|
NECT
1 minute post-contrast 10-15 minute delayed imaging |
|
what role does PET play in evaluating renal lesions
|
false + seen if its a fxning adrenal adenoma
false negatives are seen wiht mets from RCC |
|
appearance of testicular infarct
|
flow is absent
small testicle hypoechoic testicle |
|
when must detorsion be performed for testicular torsion
|
<6 hrs from time of onset
|
|
grayscale appearance of a torsed testicle
|
may initially be nml, but then the testis becomes swollen and hypoechoic b/c of edema
|
|
role of doppler in testicular torsion
|
abscence of blood flow occurs by 4 hors
if torsion is partial, it may manifest a relative dampening of signal on the affected side |
|
what NM study can be done to evaluate for testicular torsion
what will the findings look like |
tc99m-pertechnetate (will show decreaesd perfusion in acute cases, with absence of activity on affected side. in subacute cases, will see donut sign (central paucity of activity, with increased activity at the rim)
|
|
if blood flow is present in both testes, but is asymmetric what should be evaluated next
|
spectral waveforms should be obtained and compared to look for dampening of flow on affected side
|
|
what absolute washout % would indicate adrenal adenoma
|
>60%
|
|
formula to calculate adrenal lesion washout
|
absolute w/o = enhancement w/o / enhancement
relative w/o = enhancement w/o / immediate attenuation enhancement = immediate - noncontrast enhancement w/o = immediate - delayed |
|
what relative w/o would indicate a benign adenoma
|
>40-50%
|
|
lesions splaying the limbs of the adrenal glands most likely arise from where
|
the adrenal glands
|
|
most common cause of hematotmetrocolpos in older women
|
vaginal CA
|
|
cause of hematocolpos in oder woemn
|
cerivcal CA
|
|
complications of psoas hematomas
|
hypovolemia
abscess |
|
management of an uncomplicated psoas hematoma
|
NTD, will resorb on its own
|
|
most common cause of hydronephrosis in neonate
|
UPJ obx
|
|
post-obx atrophy
|
decrease in size of a kidney after relief of chronic obx
|
|
pathophys of post-obx atrophy
|
in pts with chronic unilateral urinary tract obx and hydro, renal parenchyma atrophies although the size of kidney doesn't decrease b/c fo large dilated cs
when obx is relieved, the kidney collapses there is still mild prominence of the cs even after obx is relieved |
|
before what age can the contralateral kidney hypertrophy as compensation for post-obx atrophy
|
<40 yo
|
|
how to differentiate post-obx atrophy from renal vasc disease
|
cs never retunrs to nml even after relief of chronic obx and there is always some residual dilatation
this does not occur in vascular atrophy |
|
next step when you see a bladder tic
|
always look for a cause of bladder outlet obx and evaluate for hydroureteronephrosis
also, always eval tic for focal wall thickening of filling defects that may suggest malignancy |
|
most common site of undescended testes
|
inguinal canal
|
|
before what age does an undescended testicle have to be repaired in order for it to maintain fxn
|
<6 yo
|
|
calcified testiculuar mass think:
|
burnt out testicular tumor
|
|
what is burnt out testicular tumor
|
the name given to a calcified scar in the testicle that is left behind after asponatneous regression of germ cell testicular neoplasm
even if the tumor has regressed, viable neoplastic cells may be present, esp to mediastinum |
|
if burnt out testicular tumor is found, next step
|
CT C/A/P to look for extra-gonadal spread
|
|
if extra-gonadal spread is seen in a burnt out testicular tumor, next step
|
orchiectomy
|
|

SCC, from the skin elements
|
|
complications of dermoid
|

first blocks venous drainage -> ovarian enlargement, then ovarian cyst wall and hemorrhage into cyst amay also occur
twisted adnexa are shortened and pull uterus ipsilaterally eventually, arterial supply is compromised -> infarct |
|
CT findings of ovarian torsion
|
well defined adnexal mass due to enlarged ovary
ipsilateral deviation of uterus fat stranding in pelvis |
|
t or f: ovarian neoplasms do not show hemorrhage
|
true, hemorrhage is a reliable sign of benignity
