What is the uterine pathology where there is an invasion of endometrial tissue into the myometrium that is usually noted by thickening of the posterior uterus?
adenomyosis
What patients are at increased risk for adenomyosis?
patients with fibroids
What is the signature sonographic appearance of adenomyosis?
linear striations in uterus/venetian blinds
What is the most common benign gyn tumor and leading cause of hysterectomy and gyn surgery?
leiomyoma (fibroid/myoma)
What stimulates the growth of a fibroid?
estrogen
What is the most common type of fibroid?
intramural
What is the type of fibroid that is located within the muscle wall of the uterus and does not directly change the uterine contour?
intramural
What is the type of fibroid that grows under the serosal layer and distorts the outer contour of the uterus?
subserosal
What is the type of fibroid that is adjacent to endo and distorts the endo contour?
submucosal
What type of fibroid is most likely to cause bleeding issues?
submucosal
What is the type of fibroid that grows out and attaches by a stalk?
pedunculated
What type of fibroid may resemble adnexal masses and is most likely to cause abdominal distention or pelvic pressure?
pedunculated

leiomyosarcoma
What population are leiomyosarcomas commonly found in?
perimenopausal and postmenopausal women
How do leiomyomas and leiomyosarcomas compare sonographically?
same clinical and sonographic findings except leiomyosarcomas exhibit rapid growth

What is the normal sonographic appearance of a c-section scar?
a slight indentation of the isthmus
What is a c-section scar defect?
when fluid or separation occurs
What is a c-section dehiscence?
when the myometrial walls are separating

Lippes loop
What is endometrial hyperplasia?
thickening of the endo
What does endometrial hyperplasia result from?
unopposed estrogen stimulation
What conditions can endometrial hyperplasia be secondary to?

endometrial atrophy
What appears as adhesions or synechiae within the uterine cavity as a result of scar formation after surgery or D&C?
Asherman syndrome
How does Asherman syndrome appear on SIS?
webb-like or stringy appearance and visualization of the synchiae
