“…6,7 In the remaining article, tumor detection on T2WIs was difficult. 9 The tumor did not show hypointensity on T2WIs compared to the normal uterine myometrium in any of previous cases. Histologically, ETT contains dense hyalinization and eosinophilic necrotic debris, consistent with the findings in our case.…”

Herein, we report a rare case of an epithelioid trophoblastic tumor of the uterus with radiologic-pathologic correlation in a 56-year-old postmenopausal woman. On T2-weighted magnetic resonance (MR) imaging, the tumor appeared as a hypointense irregular mass compared with the surrounding myometrium of the uterine corpus and encircled the cavity of the lower uterine segment. On dynamic contrast-enhanced MR images, the tumor appeared as a hypovascular mass and an inhomogeneously hyperintense mass in the delayed phase. In addition, non-contrast computed tomography images showed some spotty areas of very high density within the tumor. These radiologic findings were well correlated with the histological features, such as abundant hyalinization and calcification within the tumor. Accurate interpretation of MR and computed tomography findings was helpful to differentiate epithelioid trophoblastic tumor from other gestational trophoblastic diseases and uterine carcinomas.

“…Kara et al have reported a case of uterine ETT diagnosed by fractional curettage, it was difficult to detect tumor as its intensity was similar to that of a normal endometrium. 5 Last case was well-circumscribed tumor containing hypoenhanced area reported by Okumura et al, and it was diagnosed ETT with necrotic cell debris. 7 …”

“…ETT is a rare disease, so few studies have reported on the radiographic findings seen in uterine ETT. Although there is no previous report focused on CT or MRI findings, and only PET-CT findings has been reported, 5 there are three clinical or pathological reports that contained MR images. 5 – 7 This report aimed to identify some keys to the presurgical differential diagnosis of ETT, namely, CT or MRI findings that would be incompatible with a diagnosis of uterine carcinoma, referring to pathological findings and MR images of previous reports.…”

MR Imaging of Uterine Epithelioid Trophoblastic Tumor: A Case Report

et al. 2016

Epithelioid trophoblastic tumor (ETT) is a rare gestational trophoblastic neoplasm of chorionic-type intermediate trophoblasts, and it is most frequently located in the lower uterine segment and endocervix. Due to the epithelial-growth pattern with geographic necrosis exhibited by the neoplastic cells, ETT is commonly confused, both clinically and pathologically, with squamous cell carcinoma. Although there have been no previous reports of ETT focusing on computed tomography (CT) or magnetic resonance imaging (MRI) findings, we report a case of uterine ETT with special attention to the MRI findings referring to the pathological findings and MR images of previous reports. A 42-year-old Japanese woman (gravid 1, para 1) presented with uterus enlargement during screening, and complained of recent-onset lower abdominal pain. The MRI showed a solid tumor throughout the entire myometrium of the lower uterine segment, with the hemorrhagic cystic portion extending to the posterior subserosal space. Following hysterectomy, the final pathological diagnosis was ETT. An ETT is essentially a solid tumor composed of intermediate trophoblasts that exhibit an epithelial-like growth pattern and contain geographic necrosis with calcification. In our case, MRI revealed a non-specific-intensity solid tumor in the lower uterine segment with massive necrosis and hemorrhage extending to the subserosa. While it is difficult to distinguish between ETT and uterine carcinomas, recognition of certain tumor shapes and necrosis could enable more accurate diagnosis before treatment.
