Referred for pelvic ultrasound as first line investigation
Liver functions and liver scan
The patient was managed by the clinicians as a young patient with choriocarcinoma
Gestational trophoblastic neoplasia represents a spectrum of diseases of which choriocarcinoma known to be one of the most
malignant neoplasms affecting women. This epithelial tumor is composed of highly anaplastic strands of interlacing
syncytiotrophoblastic and cytotrophoplasic elements.
Classification of gestational trophoblastic neoplasms:
Increased risk in the age groups younger than 20 years and older than 40 years and a history of previous miscarriage or molar pregnancy
Gray scale imaging:
Making the diagnosis hydatidiform mole is important because after the mole has been evacuated from the uterus these
women must have careful follow-up to exclude subsequent development of choriocarcinoma. The classic ultrasound appearance
of a hydatiform mole will result in multiple small sonolucent areas which correspond to the "grape-like" vesicles that one
sees on gross pathologic examination. When the products of conception undergo further hydropic change and proliferation
with neo-vascularization a chorio-carcinoma develops. On ultrasound the tissue becomes more hyperechoic with less sonolucent areas. Refer to images.
Typically displays a colour-coded "hot" area representing pre-existing and newly formed vessels. All of these vessels show high-velocity,
low-impedance blood flow signals. Colour Doppler flow imaging and pulsed Doppler can be used to evaluate chemotherapeutic results
Choriocarcinoma tissue does not contain any HLA anti-bodies( like sperms) which may explain way it is so highly malignant -
the body does not recognize it as foreign.
