Ectopic pregnancy is a leading cause of pregnancy-related deaths; its incidence has progressively increased in recent years. Spontaneous twin ectopic pregnancy, however, is extremely rare. Among more than 100 reported cases of twin tubal pregnancies, only 5 cases in which fetal cardiac motion has been visualized in both embryos have been reported. We describe an additional case of a live monochorionic twin ectopic pregnancy in a patient with no predisposing factor. With transabdominal sonography, we initially diagnosed a single ectopic pregnancy, visualized as an ill-defined mass in the left adnexa. However, with transvaginal sonography, we determined the left adnexal mass to contain a single monochorionic gestational sac with 2 embryos, each with cardiac motion. These findings were confirmed with color Doppler sonography and at laparotomy. The introduction of high-resolution transvaginal sonography has resulted in the earlier diagnosis of ectopic pregnancy and has contributed to a recent decrease in the maternal mortality and morbidity associated with this condition.
Osseous haemophilic pseudotumours are uncommon. Mandibular haemophilic pseudotumours are rare, with only approximately 12 cases reported in the literature to date. We present imaging findings of a histopathologically proven mandibular haemophilic pseudotumour. A fluid-fluid level, hitherto not associated with this condition, is also described.
Russels's viper bite victims with systemic poisoning may present with hemorrhagic manifestations, including spontaneous bleeding and incoagulable blood associated with disseminated intravascular coagulation and primary fibrinolysis, two of the most prominent manifestations of the systemic envenoming by this species. Various vascular complications of viperine snake bite have been reported in the literature. We report the computed tomographic findings in a case of snake bite resulting in hemoperitoneum, which, to the best of our knowledge, has not been reported in the literature.
Two cases of saccular aneurysms of the infrarenal inferior vena cava (IVC) associated with retrohepatic IVC obstruction are described. Ultrasonographic, computerized tomographic and inferior venacavography findings in these cases are presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
