What is the characteristic appearance of gestational trophoblastic disease (GTD) on ultrasound?
Thickening of the uterine lining.
Enlargement of the fallopian tubes.
Grape-like clusters in the placenta.
Multiple cysts in the ovaries.
The Correct Answer is C
Choice A rationale
Thickening of the uterine lining is not characteristic of gestational trophoblastic disease (GTD). Instead, GTD involves abnormal growth of trophoblast cells, which form part of the placenta, leading to its distinct appearance.
Choice B rationale
Enlargement of the fallopian tubes is not associated with GTD. GTD involves abnormal placental development rather than tubal changes. Ultrasound imaging reveals characteristic findings in the placenta.
Choice C rationale
GTD's hallmark ultrasound finding is grape-like clusters in the placenta, indicative of molar pregnancy. This appearance results from the proliferation of abnormal trophoblast cells and hydropic villi.
Choice D rationale
Multiple cysts in the ovaries are not characteristic of GTD. This description may relate to polycystic ovary syndrome (PCOS) but does not align with GTD’s specific ultrasound findings involving the placenta.

Choice C rationale
Uterine tenderness results from inflammation and bleeding within the uterine wall at the site of abruption.

Choice C rationale
Caput succedaneum is edema of the newborn's scalp that crosses suture lines, commonly resulting from vacuum-assisted delivery.
