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
appearance of hydrosalpinx on HSG
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
what type of malignancy results if a teratoma has malignant degeneration
SCC, from the skin elements
complications of dermoid
ovarian torsion
chemical peritonitis
pathophys of ovarian torsion
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
