Background & Objective: Considering the heterogeneity in the brachytherapy treatment process for cervical cancer in Iran, the Radiation Oncology Research Center of Tehran University of Medical Sciences) developed a guideline on brachytherapy for the treatment of patients with cervical cancer in cooperation with the Atomic Energy Organization of Iran, Cancer Research Institute, Iranian Society of Radiation Oncology, Iranian Association of Medical Physics, and Cancer Administration of the Ministry of Health and Medical Education.
Methods and Materials: This study was designed with the aim to provide a standard protocol of brachytherapy for the treatment of cervical cancer by the Iranian Brachytherapy Society at Radiation Oncology Research Center, Tehran University of Medical Sciences, Tehran, Iran in 2020.
Results: These guidelines, which address the principles and details of brachytherapy for cervical cancer, were localized and developed based on the references listed in the supporting document. This document was mainly developed based on a localized version of the American Brachytherapy Society (ABS) guidelines.
Conclusion: Brachytherapy should be introduced as a necessary part of the treatment plan in patients with cervical cancers. Here, we provided a comprehensive guideline for the treatment of cervical cancer radiotherapy using high-dose-rate brachytherapy which can help medical service providers involved in the treatment of cervical cancer to provide better services to cervical cancer patients and decrease the existing heterogeneity in radiotherapy approaches in Iran.

Ovarian mature cystic teratomas (OMCTs) due to their heterogeneous histologic entity, have a wide spectrum of radiologic features. A type of floating spherical globule that has been called “Sack of marble” or "Coins-in-sack,” but without a fat or calcification component that results in misdiagnosis on computed tomography (CT), is a rare finding. The patient was a 35-year-old healthy woman with abdominal pain and sonographic findings based on OMCT with the Coins-in-sack sign, whereas the CT manifestation was a unilocular huge cyst suggesting an adnexal cystadenoma. She had a final diagnosis of the Coins-in-sack variant of OMCT but with keratin balls, not common fat balls. Understanding the unconventional radiologic and histologic manifestations of OMCTs, is necessary to make an accurate diagnosis.

Diagnosis of endometriosis according to TVS may be an appropriate alternative method for laparoscopy. Hence in this study, the role of TVS was investigated compared with laparoscopic assessment in cases with pelvic endometriosis attending to imaging center of Imam-Khomeini and Yas Hospital in Tehran in 2018. In this diagnostic study, 69 patients with pelvic endometriosis were assessed. The results of TVS were compared with laparoscopic assessment, and the sensitivity, specificity, and congruence rate were determined. According to the obtained results, it may be concluded that most sensitivity of TVS is related to the torus uterinus and dome of the bladder. Also, the most specificity is related to bladder, sigmoid colon, and peritoneal cyst. The most congruence rate between U/S and laparoscopy is at bladder trigon and sigmoid colon. However, in the end, multicenter studies with more cases and comparisons with the results of other diagnostic methods are recommended to achieve more accurate results.

Background and Objective: To evaluate the clinical course and CT findings of pregnant womenMethods: Fourthy (25 pregnant and 15 non-pregnant) patients were entered to the study. Chest CT features and clinical findings were evaluated between two groups. Data related to pregnancy and fetal status evaluated in the pregnant group.Result: The average age of pregnant patients was 33.1±5.75 years and the non-pregnant group was 35.4±6.88 years. The gestational age ranged from 7 weeks to 39weeks+2days (mean =31weeks+5days). No significant difference was seen between the two groups about clinical findings except the duration of symptoms before CT which was more in pregnant patients (6.71 ± 5.5 days vs 3.53 ± 1.92 days). Two mortalities in pregnant and one in non-pregnant patients , 2(8%) cases of premature rupture of membranes (PROM), 3 (12%) cases of intra-uterine fetal death (IUFD), 3 (12%) cases of fetal distress and 2 (8%) cases of IUGR in pregnant group. Fifteen pregnant patients gave birth .No positive PCR result was detected in newborns. Unlike the control group, the common CT findings were ground-glass pattern.Conclusion: In summary, although we found the clinical findings in pregnant and control group were similar but pattern of CT involvement was different in pregnant patients and rate of ICU admission and mortality rate were more than control group. This viral pneumonia was associated with some important complications such as IUFD in severely involved mothers. CT could be an efficient tool for the early detection and severity assessment in the pregnant patients with COVID-19 pneumonia.

Background and Objective: Conjoined twins (CTs) are rare complications of monozygotic twinning. Cephalothoracopagus is the rarest subtype of CTs and occurs once in every 58 sets of conjoined twins or once in every three million births. Here we present such a case and analyze the possible reasons for ultrasonographic misdiagnosis and recommend solutions to avoid it.Case Report: In this article, we have reported a case of Cephalothoracopagus Janiceps twining. The ultrasonographic diagnosis was missed at 7 and 12 weeks scans. Increased thickness of nuchal translucency and absent nasal bone was observed alongside with suspected gastroschisis. The patient was referred for further evaluation at 13-14 weeks of pregnancy. Unexpectedly, two alive fetuses were reported fused in the head, thorax, and abdomen. Because of the poor prognosis, counseling was provided for parents and elective medical pregnancy termination was carried out. We have analyzed the possible reasons for ultrasonographic misdiagnosis.Conclusion: Without applying a standardized scanning of the entire uterus both in a longitudinal and transverse approach in early pregnancy, cephalothoracopagus twining may be misdiagnosed with a singleton pregnancy. A high level of concerns may raise for conjoined cephalothoracopagus twinning in case of finding a single fetal pole with an irregular body outline and a disproportionally large head in the presence of two separate fetal hearts in early pregnancy. Two fused heads with two brains and two sets of lower and upper extremities do confirm the diagnosis.
