A chorionic hematoma appears on ultrasound as a hypoechoic crescent adjacent to the gestational sac. The hematoma is considered small if it is under 20% of the size of the sac and large if it is over 50%. [2]
Regenerative nodule (CEUS). One can see the hypovascular pattern of the solid nodule, with a size <10 mm. [citation needed] These lesions are well defined, with isoechoic or hypoechoic appearance and sizes less than 1 cm. They are high in numbers and have a more or less uniform distribution, involving all liver segments.
A solid, heterogeneous, echogenic mass has a positive predictive value of 80%, but is present in only a minority of cases. A thickened endometrium of > 10 mm is usually considered abnormal, though no consensus exists on the appropriate cutoff.
Obstetric ultrasonography, or prenatal ultrasound, is the use of medical ultrasonography in pregnancy, in which sound waves are used to create real-time visual images of the developing embryo or fetus in the uterus (womb).
Adnexal mass; Abdominal CT shows a 7.1 × 4.3 × 5.4 cm septal cystic, solid mass was detected on the left adnexal, and the solid components were enhanced. Specialty: Gynaecology: Symptoms: Pain of the pelvic / illiac regions especially if it involves the ovaries or fallopian tubes: Types: Benign or malignant; simple or complex
The mean sac diameter [3] can effectively estimate the gestational age [4] between 5 and 6 weeks, with an accuracy of about +/- 5 days. [ 5 ] The yolk sac and embryo should be readily identifiable when the gestational sac reaches a certain size — a yolk sac should be seen when the gestational sac is 20mm and a fetal pole should be seen when ...
Velamentous cord insertion is a complication of pregnancy where the umbilical cord is inserted in the fetal membranes.It is a major cause of antepartum hemorrhage that leads to loss of fetal blood and associated with high perinatal mortality.
Pregnant patients may have bleeding from the reproductive tract due to trauma, including sexual trauma, neoplasm, most commonly cervical cancer, and hematologic disorders. Molar pregnancy (also called hydatiform mole ) is a type of pregnancy where the sperm and the egg have joined within the uterus, but the result is a cyst resembling a grape ...
