Invasive mole Radiology

Hydatidiform mole Radiology Reference Article

Hydatidiform moles are one of the common complications of gestation, estimated to occur in one of every 1,000-2,000 pregnancies 3 . These moles can occur in a pregnant woman of any age, but the rate of occurrence is higher in pregnant women in their teens or between the ages of 40-50 years. There is a relatively increased prevalence in Asia. Invasive mole is a distinct subgroup of GTN, which if not diagnosed and treated early, can result in serious complications like uterine perforation and haemoperitoneum. We present a rare case of an invasive mole of the uterus, which developed following the evacuation of a molar pregnancy of maligant Invasive Mole within the spectrum of Gestational Trophoblastic Disease (GTD) • To depict relevant MR imaging features of GTD in the initial exam and follow-up. • To emphasize in the inestimable use of MRI in detection of myometrial tumoral invasion and assessment of extrauterine spread. Background CONTENTS (Fig. 1) on page 1

Invasive mole is the most common form of persistent GTD. It almost always occurs after CHM and thus usually has a diploid karyotype that is completely paternal in origin. Choriocarcinoma is a rare type of GTN and may manifest after a hydatidiform mole, a normal pregnancy, or an abortion (3) An invasive mole has the ability to penetrate and may even perforate the uterine wall. Pathogenesis Invasive moles arise from hydatidiform moles, this tumour is locally destructive and may invade parametrial tissue and blood vessels. There is invasion of the myometrium by hydropic chorionic villi, accompanied by proliferation of trophoblast Invasive mole follows approximately 10-15% of complete hydatiform mole. The prognosis for most cases of GTN is characterized by the presence of wide spread of metastasis. Invasive mole (IM) is common manifestation of GTN characterized by the presence of whole chorionic villi that accompany excessive trophoblastic overgrowth and invasion Choriocarcinoma: both invasive mole and choriocarcinoma present with high hCG Choriocarcinoma has more stricking cytologic atypia and proliferation and has a biphasic pattern of atypical syncytiotrophoblast and cytotrophoblast; it also lacks villi (except In the rare instance of gestational choriocarcinoma An award-winning, radiologic teaching site for medical students and those starting out in radiology focusing on chest, GI, cardiac and musculoskeletal diseases containing hundreds of lectures, quizzes, hand-out notes, interactive material, most commons lists and pictorial differential diagnoses Invasive Mole; Complete Mole. Transabdominal.

Invasive mole in which penetration of molar villi, usually from a complete hydatidiform mole, occurs in the myometrium. Choriocarcinoma in which trophoblastic invasion, in the absence of chorionic villus structures, may extend into and beyond the myometrium, with the potential of metastases (in this case, the lung) 1% recurrence risk (Hum Reprod 2015;30:2055) After a molar pregnancy, the risk of a second complete mole rises to 1 - 2%; after two molar pregnancies, the risk of a third mole is 15 - 20%, which is not decreased by having a different partner (Gynecol Oncol 1999;75:224) 15 - 20% risk of progressing to gestational trophoblastic neoplasia; 10 - 15% invasive mole, 2 - 3% choriocarcinoma (Gynecol. Most of invasive moles can be diagnosed and treated based on clinical findings, without the need of pathological examination. History of mole in the antecedent pregnancy, combined with persistently high serum β-hCG and ultrasound finding of heterogenous mass infiltrating myometrium are the clinical features suggestive of invasive mole

Medical Radiology (Diagnostic Imaging and Radiation Oncology) The 3 ovarian pathologies encountered were ovarian torsion, and the two miscellaneous cases were hydrop degeneration in missed abortion and invasive mole. There was 100% correlation between MR imaging findings and the final outcome in cases with abruptio placenta, ovarian, uterine, and miscellaneous pathologies Hydatidiform moles should be regarded as premalignant lesions because 15-20% of complete hydatidiform moles (CHMs) and 1% of partial hydatidiform moles (PHMs) undergo malignant transformation into invasive moles, choriocarcinomas, or, in rare cases, placental-site trophoblastic tumors (PSTTs). [ 2, 6] Ultrasonography is the imaging. 3. Discussion. Invasive mole results from the myometrial invasion of a complete or partial mole, which does not show malignancy features but can metastasize especially to the vagina and lungs .Patients usually present with continuous vaginal bleeding since prior molar pregnancy or abortion PATIENT CONCERNS: A 27-year-old patient developed a rare invasive mole two months after a missed abortion. DIAGNOSES: A transvaginal ultrasound scan revealed a 3.6 × 2.9 × 2.4 cm sized lesion with cystic vascular areas within it, within the myometrium of the right fundal posterior region of the uterus

Persistent trophoblastic neoplasia is presumed to be invasive mole unless there is presence of metastases to suggest Choriocarcinoma. Since both invasive mole and Choriocarcinoma are usually treated with chemotherapy, histological differentiation of the two types is not needed routinely (2). 2. Magnetic Resonance Imaging (MRI Invasive hydatidiform moles develop in approximately 10% to 20% of patients after molar evacuation and infrequently after other gestations. Due to their aggressive growth characteristics, invasive moles are considered locally invasive non-metastatic neoplasms. They are defined as moles that penetrate and may even perforate the uterine wall

Gestational Trophoblastic Disease: Clinical and Imaging

Clinical Imaging: Invasive Mol

Non-invasive imaging for skin cancer, like confocal microscopy, can be used to speed up the process, because the frozen sectioning and processing time needed for a traditional microscope isn't necessary with the confocal microscope. 4. Optical imaging technology provides a new tool to diagnose skin cancers early, when they are most treatable The clinical imaging of this case initially suggested it to be a benign hydatidiform mole but ultimately was diagnosed as an invasive molar pregnancy, with human chorionic gonadotropin monitoring. Clinical imaging was used to help manage this patient, with the demonstration of trophoblastic invasion of the uterine wall Define invasive mole. invasive mole synonyms, invasive mole pronunciation, invasive mole translation, English dictionary definition of invasive mole. Noun 1. hydatidiform mole - an abnormality during pregnancy; chorionic villi around the fetus degenerate and form clusters of fluid-filled sacs; usually.. Invasive moles occur in the fertile period, with about 95% occurring after previous mole removal and the remaining 5% occurring after several other pregnancies. Patient concerns: A 27-year-old patient developed a rare invasive mole two months after a missed abortion Gestational trophoblastic diseases (GTD) comprise several entities which all arise due to abnormal growth of trophoblastic cells of the placenta. These disease processes range from benign to malignant. GTD are classified as complete hydatidiform mole, partial mole, invasive mole and choriocarcinoma. The imaging of choice for detecting trophoblastic disease is B-mode ultrasonography and color.

Ultrasound imaging of the uterus and ovaries was performed on 41 patients after completion of apparently successful cytotoxic chemotherapy for invasive mole and choriocarcinoma. Uterine volume was calculated and the echopattern of the uterus and ovaries assessed or 46,XX). It remains controversial if heterozygous/dispermic CHMs have a significantly greater risk of persistent gestational trophoblastic disease. Analysis of zygosity of CHMs with and without invasion at presentation, including invasive CHMs with concurrent atypical trophoblastic proliferations concerning for or consistent with choriocarcinoma, has not been specifically addressed.

Invasive mole derives from hydatidiform mole, but its pathogenesis remains unknown. Invasive mole arising from iatrogenic uterine perforation has not been reported yet. A reproductive woman was admitted because she suffered form severe abdominal pain and acute intra-abdominal hemorrhage after suction evacuation due to misdiagnosis as inevitable abortion Computed tomographic (CT) imaging of the chest showed bilateral pulmonary metastases and β-human chorionic gonadotropin (β-HCG) titer was 158,071 mIU/ml. Magnetic Resonance Imaging (MRI) screening of the brain showed no abnormalities. Stage III invasive mole was diagnosed The imaging of choice in a suspected hydatiform mole is a pelvic ultrasound. In a complete mole, the ultrasound findings include a heterogeneous mass in the uterine cavity with multiple anechoic spaces, most commonly referred to as a snowstorm appearance. Mittal S,Menon S, Interstitial pregnancy mimicking an invasive hydatidiform mole. They are classified into four groups, namely, invasive mole, choriocarcinoma, placental site trophoblastic tumor and epithelioid trophoblastic tumor. Approximately 15-20% of complete hydatidiform moles and 1% of partial moles develop into one of the GTNs . GTNs generally occur in reproductive age and are extremely rare in perimenopausal women Imaging tests can also be done to help determine how well treatment is working or to look for possible signs of cancer coming back (recurring) after treatment. Chest x-ray This test might be done to help determine if melanoma has spread to the lungs, although a CT scan of the chest (see below) is often done instead
