Background: Pregnancy in the rudimentary Horn of the unicornuate uterus is highly rare. Its incidence is 1 in 75000-150000 pregnancies. It is difficult to diagnose the rudimentary Horn of the unicornuate uterus before the rupture of an ectopic pregnancy. Case Presentation: The current study reports the case of a 35-year-old Iranian mother with a natural contraceptive method. The mother was a primigravida woman at the gestational age of 7 weeks, based on her last period. She complained of abdominal pain in the right and lower abdomen and had a positive pregnancy test with a beta-human chorionic gonadotropin beta-human chorionic gonadotropin (beta-hCG) titration of 38982 on May 17, 2021. The ultrasound report on May 17, 2021, showed a right adnexal mass with a size of 32*32*31 and a fetal pole, and yolk sac. A fetal heart of six weeks and one day in favor of ectopic pregnancy was detected. and its endometrial thickness was 12 mm. There were no abdominal or pelvic-free fluids. Thus, after being diagnosed with an ectopic pregnancy that included a heart, the patient was transferred to the operating room for laparoscopy. During laparoscopy, we found that the pregnancy was in the rudimentary Horn of the unicornuate uterus. The rudimentary Horn was resected, and the salpingectomy of the right side was performed for the patient. The samples were then transferred to the laboratory for pathological analysis. Conclusion: We should increase awareness about pregnancies that occur in this uterine abnormality so that there is a high suspicion index for faster diagnosis before the rupture of ectopic pregnancy and worse events can be prevented accordingly.

Uterine Horn intussusception has rarely been reported in bitches. However, the pathogenesis is not entirely clear and the incidence of uterine intussusception in bitches is unknown. This disorder occurs during the postpartum period and is a challenging clinical condition in terms of presentation, diagnosis, and management. In this report, a case of uterine Horn intussusception is described in a four-year-old female Chihuahua bitch, which presented with abdominal pain, lethargy, anorexia, tremors, recumbency, and ongoing reddish vaginal discharge 20 days after whelping two pups. All the hematological and biochemical test results were within normal ranges except for a decreased calcium level. Ultrasonographic examination revealed the multilayered appearance of the uterine wall. The midline laparotomy confirmed the invagination of a proximal segment of the uterine Horn into its distal segment near the uterine body. Ovariohysterectomy was performed as the recommended treatment. This case highlights the importance of assessing abdominal pain to avoid delay in diagnosis and management. Moreover, uterine intussusception should be considered as a differential diagnosis in bitches with the symptoms of abdominal pain during the postpartum period.

Figures 1 and 2: Brain CT shows disproportionate enlargement of temporal Horn and atrium of the right lateral ventricle with periventricular hypodensity and relatively normal sized contralateral ventricle as well as frontal Horn of the ipsilateral ventricle.The term "entrapment of temporal Horn" was first used by Maurice Williams, et al, to describe focal ventricular dilatation of the temporal Horn caused by occlusion of the cerebrospinal fluid (CSF) pathway at the atrium of the lateral ventricle....

Introduction: Rudimentary Horn pregnancy (RHP), an entity with a diagnostic dilemma is known to rupture most commonly in second trimester, sometimes in early third trimester. This case of ectopic rudimentary Horn (RH) presented acutely in the first trimester.Case Presentation: A 30 years old G3P2L2 with previous two vaginal deliveries presented with acute abdominal pain and features of hemorrhagic shock at 8 weeks 5 days gestational age. With clinical diagnosis of ruptured ectopic pregnancy, the patient immediately underwent laparotomy, which revealed hemoperitoneum with a unicornuate uterus along with ruptured RHP. RH excision with ipsilateral salpingectomy and right tubal ligation was done and the maternal life salvaged.Conclusion: High index of suspicion based on clinical history and examination complemented with diagnostic radiological modalities can help in prenatal and pre-rupture diagnosis of RHP, hence its prompt treatment to alleviate scope of any emergency situation and the disastrous consequences leading to maternal morbidity and mortality.

An axially corrugated Horn antenna with an elliptically shaped taper is proposed for satellite communication applications. This structure is a good candidate for the feed of reflectors and also for improving the electrical properties of reflector antennas. A tapering method is used to justify the horizontal location of the corrugation profile which improves the electrical performance of the presented antenna. The simulation results of a conventional axial corrugated Horn antenna with a linear taper are compared to those of the proposed antenna. These results illustrate that the cross-polarization, side-lobe level and return loss of our antenna are improved by about 16dB, 4dB and 9dB, respectively. The axial corrugated Horn antenna with an elliptical tapering function is simple and low-cost as compared to the other corrugated Horn antennas such as scalar (vertically) corrugated Horn and subsequently, it could be preferred in commercial applications.
