Familial Mediterranean fever (FMF) is a juvenile-onset autoinflammatory disease involving recurrent peritonitis. Although the pathogenesis of the disease remains unclear, FMF is caused by dysfunction of the pyrin protein, which suppresses t…

ObjectivesTo investigate the frequency and patterns of calcification in ovarian tumours and evaluate their association with various histological types and malignancy grades.MethodsThis retrospective study included patients who underwent non…

Low-grade endometrial stromal sarcoma (LGESS) is a rare mesenchymal tumor of female genital tract malignancies. While it primarily arises in the uterus, extrauterine cases, including those originating in the ovary, are exceedingly rare. Whi…

BACKGROUND: Preoperative assessment of the histological type of ovarian cancer is essential to determine the appropriate treatment strategy. Tumor location may be helpful in this regard. The purpose of this study was to compare the position…

BackgroundThis study aimed to compare deep learning with radiologists' assessments for diagnosing ovarian carcinoma using MRI.MethodsThis retrospective study included 194 patients with pathologically confirmed ovarian carcinomas or borderli…

BackgroundOvarian clear cell carcinoma (OCCC) is one of the most lethal types of ovarian cancer. Early-stage OCCC can be cured by surgery; however, advanced-stage disease shows poor prognosis due to chemoresistance unlike the more common hi…

PurposeTo verify whether deep learning can be used to differentiate between carcinosarcomas (CSs) and endometrial carcinomas (ECs) using several magnetic resonance imaging (MRI) sequences.Material and methodsThis retrospective study include…

Elevated serum levels of cancer antigen 125 (CA125) are known to occur in adenomyosis. However, the relationship between the severity of adenomyosis and serum CA125 levels has not yet been elucidated. The present study aimed to examine the …

PurposeTo clarify imaging and clinical characteristics of ovarian carcinosarcoma (CS) compared with high-grade serous carcinoma (HGSC).MethodsWe retrospectively reviewed MR imagings of 12 patients with CS and 30 patients with HGSC and evalu…

We report the case of a 30-year-old woman who complained of a painful palpable mass. Magnetic resonance imaging revealed an ill-defined mass approximately 8 cm in diameter with internal microcytic components. The mass diffusely involved the…

BACKGROUND: Primary epithelial ovarian carcinoma is sub-classified into serous, mucinous, endometrioid and clear cell subtypes. Neoadjuvant chemotherapy has become an alternative treatment option past several years, as serous carcinoma, the…

A patient who underwent fertility-sparing surgery for Stage IA clear cell carcinoma may have developed de novo clear cell carcinoma in the contralateral ovary 9 years later. She underwent fertility-sparing surgery and postoperative adjuvant…

ObjectiveTo determine the long-term outcomes of patients with an isolated ovarian recurrence after fertility sparing surgery (FSS) for epithelial ovarian cancer (EOC) and to evaluate the recurrence rates (and location) according to the new …

Dienogest is a novel synthesized progestin used for treatment of endometriosis. This is the first case report describing a therapeutic effect of dienogest on a gynecologic malignancy. The patient was a 44-year-old woman with advanced adenos…

OBJECTIVE: Although mural nodules are considered to be the most important hallmark in the recognition of ovarian cancers accompanied with endometriotic cysts, benign neoplasms and even inflammatory diseases can show similar MRI findings. We…

A 29-year-old woman presented with bilateral hydronephroses concomitant with acute renal failure. Retrograde pyelography demonstrated bilateral ureteral strictures located at the lower segment of ureters. Computed tomography revealed inflam…

Ovarian cancer, and clear cell carcinoma in particular, reportedly increases the risk of venous thromboembolism (VTE). However, the mechanisms remain unclear. Tissue factor (TF) supposedly represents a major factor in the procoagulant activ…
