Chorioangioma is a benign vascular tumor of the placenta arising from primitive chorionic mesenchyme. Large (>4 cm) chorioangiomas are much rarer and are often associated with maternal and/or fetal complications. We describe the sonographic features of a large placental chorioangioma with normal outcome.
Renal Doppler sonography resistive index and pulsatility index values can serve as early radiologic predictors of renovascular changes in sickle cell disease. Thereby, these findings can guide clinicians in the use of more intensive monitoring of laboratory values and initiating adequate treatment at an early stage.
Midgut volvulus can also appear much beyond the neonatal age group with a variety of clinical presentations, making the clinical diagnosis in such patients very difficult, if not impossible. Identification of the clockwise whirlpool sign on sonography is an accurate way of diagnosing this condition, which can preclude the need for further investigations and can allow prompt surgical intervention.
Mucocele of the appendix is a rare but well-known entity. Accurate preoperative diagnosis of this surgically curable entity is very important to prevent intraoperative rupture. With multimodality approach using ultrasound and CT, it has been possible to preoperatively diagnose mucocele of the appendix. We describe the ultrasound and CT findings of a giant appendicular mucocele that led us to the correct preoperative diagnosis.
Anomalous origin of vertebral arteries is not common and usually seen as an incidental finding on imaging. We report a case of anomalous origin of left vertebral artery from left carotid bulb ("trifurcation" of left common carotid artery) on magnetic resonance angiography in a 64-year old male who also had ipsilateral thalamic acute infarct.
Mesenchymal chondrosarcomas, although very rare compared with conventional chondrosarcomas, are one of the few primary malignant tumours of bone that sometimes also arise in the soft tissues. Here we present a rare case of retroperitoneal extraskeletal mesenchymal chondrosarcoma (ESMC) in a 50-year-old female that showed characteristic extensive calcification. In this report, we discuss CT features of ESMC with pathological correlation.
ABSTRACT:We report the sonographic findings of a rare case of uterine rupture with extrusion of the fetus into the broad ligament during a second-trimester abortion. Sonography revealed the empty uterus with an indistinct defect on the side wall and the dead fetus lying outside, surrounded by a thin membrane. At surgery, the uterine rupture was confirmed with the fetus lying in the broad ligament. This study shows the importance of timely sonography in second-trimester abortion, enabling immediate management and preventing further complications. Keywords: ultrasound; uterine rupture; broad ligament; second trimester; abortion; ethacridine U terine rupture during pregnancy is usually due to disruption of a previous cesarean scar during delivery and rarely occurs in midtrimester abortion. In women with previous cesarean delivery, the use of oxytocic agents like prostaglandins for labor induction during the second or third trimester increases the risk of uterine rupture.
Retroperitoneal fibrosis is one of uncommon cause of obstructive uropathy. Aortic dissection without rupture is still uncommon cause of retroperitoneal fibrosis. We present unusual case of aortic aneurysm with dissection without its acute rupture causing retroperitoneal fibrosis with its contrast computed tomography features. We report imaging features of computed tomography of abdominal aortic dissection complicated by retroperitoneal fibrosis with bilateral ureteral obstruction. The patient underwent successful bilateral transurethral ureteral stenting to relieve acute obstruction and started on corticosteroid treatment.
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.
