6
constitute 10% of adnexal masses found in the broad ligament specifically, mesosalpinx (ovary ~fallopian tube) 3 types of cysts - 68% : mesothelial origin - 30% : paramesonephric elements - 2% : mesonephric origin
7
found over a wide age range most common in the third and fourth decades (Paramesonephric cysts rarely occur before puberty) vary greatly in size(from tiny to massive) Larger cysts tend to be seen in younger patients (usually of mesothelial origin) rarely bilateral or multiple, Hemorrhage, torsion, rupture, or secondary infection are infrequent complications
8
Neoplasms occur 2% of cysts Pathologically->serous cystadenomas, serous adenofibromas, papillary serous malignancy, and cystadenocarcinoma Neoplasms have been seen in cysts as small as 4 cm
9
Symptom - lower abdominal pain - menstrual irregularities - increased abdominal girth (due to displacement of pelvic organs by the cyst)
10
Sonographically - thin walled, unilocular with anechoic contents - Large parovarian cysts may be located superior to the uterus mimicking the urinary bladder - Unlike physiologic ovarian cysts, parovarian cysts do not change over the course of the menstrual cycle or with hormonal administration
11
- Eccentric ovarian cysts occurring at the ovarian edge, can be mistaken for parovarian cysts - They can be differentiated by identifying crescentic shaped ovarian tissue surrounding a portion of the ovarian cyst margin.
12
Hydrosalpinx - anechoic, thin walled cyst - typically tubular appearance - Additionally, clinical findings of pelvic inflammatory disease help distinguish this from a parovarian cyst
