Common cyst or ovarian mass
|
*follicular cyst
*corpus luteum cyst of pregnancy *cystic teratoma *paraovarian cyst *hydrosalpinx *endometrioma (low-level echoes) *hemorrhagic cyst |
|
|
Common complex masses
|
*cystadenoma
*dermoid cyst *tube-ovarian abscess *ectopic pregnancy *granulosa cell tumor |
|
|
Common solid masses
|
*solid teratoma(a tumor composed of various tissues such as bone, hair, and teeth not normally found together at the site of origin and probably derived from embryonic remnants.
They most often occur in the ovary, where they are benign, and in the testis, where they are malignant.) *adenocarcinoma *arrhenoblastoma *fibroma *dysgerminoma *torsion |
|
|
Functional cysts
|
Functional cysts result from the normal function of the ovary. they are the most common cause of ovarian enlargment in young wemon. functional cyst include: -follicular -corpus luteum -hemorrhagic -theca-lutein cyst(>5cm)
|
|
|
Folicular cysts
|
A follicular cyst forms when a mature folicle fails to ovulate or involute. these cyst are usually unilateral, asymptomatic, and less than 2cm in diameter.
*occur when a dominant follicle does not succeed on ovulating and remains active though immature *usually unilateral *thin-walled, translucent, watery fluid, may project above or within surface of the ovary *may grow 1 to 8 cm *usually disappear spontaneously by resorption or rupture *clinical:asymptomatic to dull, adnexal pressure and pain, abnormal ovarian function, tortion of the ovary resulting in sever pain *sonographic finding:simple cyst |
|
|
corpus luteum cysts
|
Corpus luteum cysts result from failur of absorption or from excess bleeding into the corpus luteum.(>4cm).often pain.
*result from hemorrhage within a persistently mature corpus luteum *filled with blood and cystic fluid * may grow 1-10 cm in size *may accompany intrauterine pregnancy(IUP) *clinical:irregular menstural cycle, pain, mimic ectopic pregnancy, rupture *sonographic finding:"cystic" type of lesion; may have internal echoes secandary to hemorrhage |
