Q

Nabothian cyst

A

Tiny cysts at surface of cervix, 1-4mm, mucous filled though secretion of cervical glands. no symptoms.

ultrasound:
1-4mm,
anechoic, well defined cystic lesion near the endocervical canal. acoustic enhancement.
cervical region will appear large if cysts are large.
Color doppler shows no associated color flow.

Q

Cervical polyp

A

Small, fragile, elongated benign tumor found in the cervix at the surface inside or outside.
ultrasound:
1-2cm
pedunculated well circumscribed mass within the endocervical canal.
hypoechoic or echogenic
stalk attaching to the cervical wall can be identified.
doppler shows a single feeding vessel running along the length of the polyp.

Q

endometriosis

A

problem in women of childbearing age when the endometrial cells normally found inside the uterus, grow outside of the uterine cavity and its muscles. escapes during menstruation the cells escapes and can attach themselves to the ovaries, uterine ligaments and peritoneum. these ectopic cells still respond to hormones and undergo cyclic changes, bleeding during menstruation.

Q

Follicular cyst

A

when the follicle does not break open to release the egg and continues growing. no symptoms reach up to 4cm.
ultrasound:
thin walled and unilocular
posterior acoustic enhancement
absence of internal echoes
no color flow, nodules or ant solid components.
range between 3-8cm
if smaller than 3cm = ovarian follicle.

Q

malignant

A

Absence of the crescent sign (normal ovarian tissue around/ adjacent tot the adnexal mass). the larger the tumor the higher the chance of malignancy. a simple cyst <4cm is small.
irregular solid tumor.
ascites
at least four papillary structures
irregular multicolor tumor with largest diameter at 10cm.
high color content on color doppler examination.

17
Q

benign

A
