“…In this study we first aimed to monitor uterine‐lesion modifications, by means of gray‐scale and power Doppler, before and after MTX treatment in Stage‐I low‐risk GTN patients. Response to chemotherapy may be related either to dimensional or echogenic changes within the myometrial lesions or to reduction of blood supply assessed by Doppler ultrasound11. Second, we investigated whether signs of response at TVS may have a role in identifying patients not needing a switch to second‐line chemotherapy, thus differentiating chemoresistant patients from delayed responders.…”

Data from techniques such as limiting oxygen index, thermal analysis, scanning electron microscope, heat deformation curve, mechanical properties measurement, etc. show that cured epoxy resin modified by brominated castor oil possesses good flame retardation, toughness, moderate smoke suppression, and some degree of resistance to heat. © 2002 Wiley Periodicals, Inc.

“…[4] Gray scale findings include a myometrial nodule that can either be hyperechogenic[67] or echopoor. [4] Alternatively, the tumoral mass is composed of anechoic cystic spaces which either represent extensive necrosis or vascular channels (arterio-venous shunts).…”

“…[4] Alternatively, the tumoral mass is composed of anechoic cystic spaces which either represent extensive necrosis or vascular channels (arterio-venous shunts). [7] This cystic appearance can mimic a mole, retained products of conception (RPOC), or arteriovenous malformation. Characteristic of CC is the presence of trophoblastic signals on spectral Doppler ultrasound, which include a high PSV with low impedance flow (due to arteriovenous shunts), a low RI, and color aliasing.…”

Choriocarcinoma is a human chorionic gonadotrophin (HCG)-secreting tumor that comprises vascular channels. It has a tendency for widespread metastasis, common sites for which include the lung, vagina, brain, liver, bone, intestine, and kidney. We describe a 30-year-old female who presented with hepatitis-like features and bilateral diminution of vision, and subsequently developed hemothorax and hemoperitoneum—all rare and seemingly unrelated manifestations which were finally attributable to metastases from gestational choriocarcinoma. To further complicate the clinical scenario, the serum HCG of the patient was mildly raised (due to a phenomenon called hook effect). Subsequently, the patient developed disseminated intravascular coagulation and succumbed to her illness. In this report, we discuss the imaging findings of choriocarcinoma, its potential sites of metastases, and the hook effect.

“…TVUS fi ndings of GTN are described as hypoechoic areas in the endometrium and intramyometrial nodules [ 53 ], clusters of high amplitude echoes within the myometrium representing invasive tumor with echo-free areas representing hemorrhage [ 54 ], and multiple "serpinginous anechoic channels" throughout the central part of the uterus [ 51 ].…”
