Clinical Features:
A 22 years old female patient came with
- Amenorrhoea for 4 months
- Small pervaginal bleeding for several days
Ultrasound Features:
- Bulky uterus.
- Heterogeneously echogenic central intrauterine mass with internal diffuse cystic spaces is seen without any associated fetal part forming the ‘snow-storm’ appearance.
- Color Doppler shows low impedance flow towards the lesion.
Remember:
- Molar pregnancy can be easily diagnosed on transabdominal ultrasound. TVS & MRI help exclude invasive mole.
- Tornado-shaped bridging vessels, myometrial thinning & exophytic mass should be excluded.
Ultrasound Images:
