Diagnostic value of PET/CT is similar to that of conventional MRI and even better for detecting small peritoneal implants in patients with recurrent ovarian cancer.

ObjectiveThe aim of this study was to evaluate the diagnostic value of 2-(fluorine-18)-fluoro-2-deoxy-D-glucose (18F-FDG) PET/CT in comparison with MRI for the detection of recurrent ovarian cancer. MethodsForty-seven patients with suspected ovarian cancer recurrence after total ablative or cytoreductive surgery, as well as neoadjuvant or adjuvant chemotherapy, who had undergone 18F-FDG PET/CT imaging were recruited for the present study. All patients also underwent MRI within a month of 18F-FDG PET/CT for the same purpose. Recurrent cancer in the abdomen and pelvis was evaluated in each of the 47 patients and classified as either distant metastasis or local pelvic recurrence involving the vaginal stump, peritoneal implants, supradiaphragmatic region, and/or abdominal and pelvic lymph nodes. Special attention was paid to peritoneal implants. These were divided into five groups according to size of the implants: less than 0.5 cm (group 1), 0.5–1 cm (group 2), 1–2 cm (group 3), 2–3 cm (group 4), and larger than 3 cm (group 5). PET/CT findings were compared with abdominopelvic MR findings. Statistical analysis was carried out using the Wilcoxon signed rank test. ResultsThirty-nine of 47 patients were found to have recurrent ovarian cancer. Both PET/CT and MRI were negative for recurrence in six patients. Overall sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of PET/CT were 97.5, 100, 100, 87.5, and 97.8%, respectively, whereas those of MRI were 95, 85.7, 97.4, 75, and 93.6%, respectively. For the peritoneal implants in groups 2 and 3, the sensitivity, negative predictive value, and diagnostic accuracy values of PET/CT were significantly better than those of MRI (P<0.05). ConclusionThe present study revealed that PET/CT is similar to conventional MRI for the detection of recurrent ovarian cancer. PET/CT has greater accuracy in the detection of small-to-medium-sized (<2 cm) peritoneal implants compared with MRI. This may affect surgical decision making.

Pouch sign in prenatal diagnosis of esophageal atresia

Visualization of a pouch in the fetal neck or mediastinum during fetal swallowing has been proposed for the prenatal diagnosis of esophageal atresia1–4. This is a reliable finding and all reported cases with a blind-ending pouch in the neck have subsequently been confirmed to have esophageal atresia. However, possibly due to the technical difficulties involved in the visualization of the pouch, only 12 cases have been reported to date1–5. The pouch sign may also be useful in the determination of postnatal outcome. We have diagnosed two new cases of congenital esophageal atresia by detecting an upper neck pouch sign, and here we discuss the prognostic value of this finding according to the location of the pouch. Our first case was a 36-year-old woman, gravida 3 para 2, with gestational diabetes who was referred to our unit in the 34th week of pregnancy with severe polyhydramnios. The fetal stomach was small and the abdominal circumference was below the 10th percentile. We detected a 13-mm pouch in the upper mediastinum during fetal swallowing (Figure 1). There was no other associated fetal abnormality and no chromosomal abnormality. A 2700-g girl, measuring 47 cm in length and with Apgar scores of 9 and 10 at 1 and 5 min, respectively, was delivered vaginally in the 37th week. Barium radiography showed esophageal atresia without a fistula (Figure 2). On day 2 postpartum simple primary anastomosis was accomplished, and after an uneventful recovery, the infant was discharged on the 13th postoperative day. In our second case the mother was 22 years old, gravida 2 para 1, and in the 31st week of pregnancy. Sonographic

Imaging features of postpartum uterine rupture: a case report

We present a case report on a postpartum uterine rupture with the history of a previous cesarean section. During the diagnosis of rupture, ultrasound, computerized tomography (CT) and magnetic resonance imaging of the uterus were obtained. Ultrasound examination did not result in substantial information. CT and magnetic resonance imaging established the correct diagnosis. The patient underwent exploratory laparotomy, and the diagnosis was confirmed. Diagnostic qualifications of these three instruments were compared.

Uterine artery embolization in a 10-week cervical pregnancy with coexisting fibroids.

A 36‐year‐old woman, gravid 3, para 1, abortus 1, was admitted to our department at 10 weeks and 4 days of gestation with the diagnosis of cervical pregnancy and multiple uterine fibroids. After admission she underwent angiographic embolization of bilateral uterine arteries followed by intraamniotic 70‐mg methotrexate injection. Despite being given a second dose of methotrexate injection 1 week later, the gestational sac did not resolve spontaneously, thus vacuum evacuation and curettage of the cervical canal was required on the 15th day of embolization. The patient was discharged in good condition. She had no complaints by post‐operative at month 11, except amenorrhea. Her uterine fibroids markedly decreased in size after the procedure. As a result, embolization of uterine arteries provided surgical evacuation of cervical pregnancy with minimal hemorrhage, and the patients potential fertility was preserved, but a long‐term amenorrhea was observed.

Clinicopathologic and survival analyses of synchronous primary endometrial and epithelial ovarian cancers

The aim of the study was to describe clinicopathologic characteristics, survival outcomes and the factors associated with recurrence in patients diagnosed with synchronous primary endometrial and epithelial ovarian cancers.

Surgical Treatment of Metastatic Ovarian Tumors From Extragenital Primary Sites.

Objective The purpose of this study was to investigate the outcomes and prognostic factors of metastasectomy in patients with metastatic ovarian tumors from extragenital primary sites. Materials and Methods All patients with pathologically confirmed metastatic ovarian tumors between January 1997 and June 2015 were included in this study. A total of 131 patients were identified. The data were obtained from the patients’ medical records. Clinicopathological features were evaluated by both univariate and multivariate analyses. Results The primary sites were colorectal region (53.4%), stomach (26%), and breast (13%). Preoperative serum CA 125 and CA 19-9 levels were elevated in 29.4% and 39.8% of the patients, respectively. Cytoreductive surgery was performed in 41.2% of the patients. Seventy-three (55.7%) patients had no residual disease after surgery. Sixty-six (49.6%) patients had combined metastases at the time of the surgery to sites including the liver, pancreas, lung, bone, lymph nodes, bladder, or the intestine. With a median follow-up of 33 months, the median survival time was 22 months. The estimated 5-year survival probability is 0.26. On univariate analysis, primary cancer site, combined metastasis outside the ovaries, residual disease, preoperative serum CA 125 and CA 19-9 levels, and histologic type were significant parameters for overall survival. Furthermore, residual disease, preoperative serum CA 19-9 level, and primary cancer site were found to be independent prognostic factors on multivariate analysis. Conclusions The most common primary sites for ovarian metastasis are gastrointestinal tract. Metastasectomy may have beneficial effects on survival, especially if the residual disease is less than 5 mm. Prospective studies warranted to evaluate the value of metastasectomy in patients with ovarian metastasis.

Combination of adjuvant chemotherapy and radiotherapy is associated with improved survival at early stage type II endometrial cancer and carcinosarcoma

The aim of this study was to describe the impact of postoperative adjuvant treatment modalities and identify risk factors associated with recurrence and survival rates in women diagnosed with early stage type II endometrial cancer and carcinosarcoma.

Aggressive Angiomyxoma of the Pelviperineum: Surgical Treatment through a Perineal Incision

Aggressive angiomyxoma is a rare benign tumor of the pelvic soft tissue in women of reproductive age. The tumor is locally infiltrative and tends to recur. Herein is presented a case report of aggressive angiomyxoma that was totally excised using a transperineal approach. A 35-year-old woman had an aggressive angiomyxoma of the vulva and pelvis, with swelling of the right labium majus pudendi. Three years previously, she had undergone incomplete excision of the same type of pelviperineal mass via the transabdominal route. After a complete workup, a transperineal minimally invasive approach was used to excise the 20-cm mass filling the right side of the pelvis. Histopathologic findings were consistent with a diagnosis of aggressive angiomyxoma. Although often misdiagnosed as various other benign genital disorders, angiomyxoma usually is manifested as a soft nontender mass. After a thorough examination and full radiologic workup, a small transperineal incision may be sufficient for complete removal of the tumor.

Uterine perivascular epithelioid cell tumor coexisting with pulmonary lymphangioleiomyomatosis and renal angiomyolipoma: a case report.

We present a case of uterine perivascular epithelioid cell tumor (PEComa) coexisting with both pulmonary lymphangioleiomyomatosis and renal angiomyolipoma. The patient was a 42-year-old woman, suffering from massive abnormal uterine bleeding, progressive dyspnea, and arterial hypertension. Her clinical history included diagnoses of bilateral renal angiomyolipoma and pulmonary lymphangioleiomyomatosis. The patient underwent a subtotal hysterectomy and the specimen contained a subserosal tumor with irregular outlines in addition to uterine leiomyomata. The uterine tumor was histologically composed of solid sheets and tonguelike infiltration and lymphangioleiomyomalike structures within the myometrium, formed by epithelioid cells with ovoid to round nuclei and clear to light eosinophilic cytoplasms. The tumor did not display any morphologic sign of malignancy. The tumor cells showed expression of HMB-45 and smooth muscle markers. Ultrastructural analysis revealed abundant cytoplasmic microfilaments and rare small cytoplasmic bodies with a gridlike lining. We conclude that identification of lymphangioleiomyomalike growth pattern may aid in the differential diagnosis of uterine PEComa and suggest using both PEComa and smooth muscle tumor terminology.

Extrapulmonary lymphangioleiomyomatosis mimicking lymphoma metastatic to uterus

Lymphangioleiomyomatosis is a very rare disease that primarily affects the lungs. The atypical smooth muscle cells in these tumors stain both with smooth muscle markers and melanocytic markers characteristically like their counterparts in other members of the PEComa family. Extrapulmonary lymphangioleiomyomatosis, especially without pulmonary involvement, is extremely rare. The clinical importance of lymphangioleiomyomatosis lies in the fact that it may mimic other malignant diseases, such as lymphoma or sarcoma. Here, we report a case of extrapulmonary lymphangioleiomyomatosis without involvement of the lungs, in a patient pre‐diagnosed as having lymphoma metastasized to the uterus or uterine sarcoma.
