What is the normal uterus size in CM?
What is the normal uterus size in CM?
Non pregnant uterine size varies with age, number of pregnancies and patient endocrinological status, normal adult uterus measures approximately 7.2-9.0cm long, 4.5-6.0cm wide and 2.05-3.5 deep(1).
What does thickening of the uterus mean after menopause?
Endometrial hyperplasia (thickening of the uterine lining): After menopause, you may have too much estrogen and too little progesterone. As a result, the endometrium gets thicker and can bleed. Sometimes cells in the endometrium can become abnormal. This could lead to cancer, so get it treated as soon as possible.
What does a low attenuation lesion look like?
For example, a low-attenuation lesion could appear as a result of imaging on the liver, pancreas, kidney or thyroid. According to Cancer Grace, when a low-attenuation lesion appears stable over a long time frame, it can suggest something like a cyst or a collection of blood vessels in the organ.
Why is the uterus so small in premenarchal women?
Uterine zonal differentiation also depends on hormonal stimulation ( 13 ). In premenarchal and postmenopausal female patients, the uterus is typically small, with indistinct zonal anatomy because of lower circulating levels of estrogen. During pregnancy, the junctional zone becomes more hyperintense, resulting in decreased zonal distinction ( 14 ).
Is it normal to have contrast enhancement in the uterus?
Incidental findings of uterine and cervical contrast enhancement in such settings may easily be mistaken for abnormalities, given the broad spectrum of anatomic variants and enhancement patterns that may be seen in the normal uterus and cervix.
What causes diffuse myometrial enhancement in postmenopausal women?
The minimal or mild diffuse myometrial enhancement seen in the type 3 enhancement pattern, which was observed exclusively in postmenopausal women, could be related to decreased muscle mass and atheromatous changes due to aging (2).

What causes normal cervical tissue to mimic a mass?
The differential enhancement and orientation of the cervix with respect to the uterus may cause normal cervical tissue to mimic a mass. Care must be taken to differentiate between cervical neoplasms and normal cervical tissue that shows hypoattenuation relative to the enhanced uterus.
