Purpose The aim of this study was to determine the nature of incidental ovarian 18F-fluoro-2-deoxyglucose (FDG) accumulation on positron emission tomography (PET) and the correlation with the menstrual cycle and menopause.Methods We identified 19 incidental FDG accumulations in the ovary (FAOs). FDG PET images were compared with other anatomical imaging methods [magnetic resonance imaging (MRI), computed tomography (CT) or ultrasonography (US)]. Pathological findings, FDG PET scan during the next menstrual cycle and follow-up images (PET, CT and MRI) were reviewed. To establish the relation of FAOs to the menstrual cycle, we reviewed whole-body FDG PET acquired from 207 consecutive women and the pre-examination questionnaires, including data regarding the menstrual cycle.Results All spherical or discoid FAOs were attributed to normally developing ovarian follicles and corpora lutea on the basis of concurrent MRI, US or the follow-up PET scan. Three of the FAOs were proved pathologically to be either normal ovaries or a haemorrhagic corpus luteum. Fifteen FAOs spontaneously disappeared on the short-term follow-up PET scans. Of 207 women, 61 had active menstrual cycles. FAOs were found in 12 out of 61 premenopausal women (20%), appearing between the 10th and 25th days of the menstrual cycle. No FAOs were found in the women who did not have a menstrual cycle.Conclusion Physiological ovarian FDG accumulation could be found around the time of ovulation and during the early luteal phase of the menstrual cycle in premenopausal woman. Since FAO is dependent on the menstrual cycle, it can be avoided by scheduling PET just after menstruation. 相似文献

Adnexal torsion 总被引:7,自引:0,他引:7
L T Hibbard 《American journal of obstetrics and gynecology》1985,152(4):456-461
A series of 128 cases of adnexal torsion and an additional 97 cases where the preoperative diagnosis of torsion was incorrect are reviewed. The diagnosis is uncertain and surgical intervention is likely to be delayed. The adnexa are seldom salvaged despite the fact that torsion infrequently involves a malignant neoplasm. Laparoscopy is an effective means of reducing the number of necessary laparotomies when a diagnosis of torsion is uncertain. 相似文献

Optically clear nuclei (OCN) have been observed in morules of some neoplasms and in some conditions unrelated to the development of the morules. We first report a case of ovarian borderline endometrioid tumor (BET) showing the morules associated with OCN. The patient was a 47-year-old premenopausal woman with a left ovarian cystic tumor, atypical endometrial hyperplasia, and elevated serum levels of FSH, LH, estradiol, and CA 125. The resected ovarian tumor measured 6 cm in diameter, and showed a papillary growth. Histologically, the ovarian tumor was consistent with BET, and the morules with OCN were scattered. Immunohistochemically, OCN were proven to be rich in biotin. An aberrant nuclear expression of beta-catenin was observed in both the tumor cells and the morular cells. Our case may suggest the possibility that the appearance of OCN with or without morules in ovarian tumors is related to endometrioid differentiation of the tumor cells, and should be recognized as a diagnostic clue of ovarian endometrioid tumors. Although female sex hormones have been reported to play a role in the occurrence of OCN, the participation of beta-catenin mutation has also been suggested. 相似文献

Objective
To evaluate the CT findings of ruptured corpus luteal cysts.Materials and Methods
Six patients with a surgically proven ruptured corpus luteal cyst were included in this series. The prospective CT findings were retrospectively analyzed in terms of the size and shape of the cyst, the thickness and enhancement pattern of its wall, the attenuation of its contents, and peritoneal fluid.Results
The mean diameter of the cysts was 2.8 (range, 1.5-4.8) cm; three were round and three were oval. The mean thickness of the cyst wall was 4.7 (range, 1-10) mm; in all six cases it showed strong enhancement, and in three was discontinuous. In five of six cases, the cystic contents showed high attenuation. Peritoneal fluid was present in all cases, and its attenuation was higher, especially around the uterus and adnexa, than that of urine present in the bladder.Conclusion
In a woman in whom CT reveals the presence of an ovarian cyst with an enhancing rim and highly attenuated contents, as well as highly attenuated peritoneal fluid, a ruptured corpus luteal cyst should be suspected. Other possible evidence of this is focal interruption of the cyst wall and the presence of peritoneal fluid around the adnexa. 相似文献106.
目的:探讨在体外受精周期中进行垂体降调节后的血清激素水平,预测不孕症患者卵巢的反应性,为选择最佳的超促排卵方案提供依据。方法:采用化学发光法,测定69例不孕症患者接受体外受精治疗周期中,应用促性腺激素释放激素激动剂进行垂体降调节前后月经第3天的血清卵泡刺激素和雌二醇水平,按卵巢反应性指标-获卵数及刺激程度,分为低反应组,正常反应组及过度刺激组,并作统计分析。结果:降调后月经第3天血清卵泡刺激素水平与获卵数呈显著负相关(r=-0.436,P=0.001)。基础卵泡刺激素水平与获卵数呈显著负相关(r=-0.334,P=0.005)。3组比较,年龄无差异性,获卵数、受精数均有显著性差异,P<0.05;促性腺激素总用量,低反应组与其他两组比较均有显著差异,P<0.05,而正常反应组与过度刺激组比较无差异性,P>0.05。降调后3组的妊娠结局无差异,P>0.05。结论:降调后月经第3天血清卵泡刺激素水平能较敏感地预测卵巢对促性腺激素刺激的反应性,优于基础血清卵泡刺激素水平的预测作用。 相似文献
