A cesarean scar (ectopic) pregnancy occurs when a pregnancy implants on a cesarean scar. This condition is an uncommon but potentially devastating occurrence. The incidence is increasing as cesarean deliveries become more common. Early recognition of the salient sonographic findings is critical because a delay can lead to increased maternal morbidity and mortality. Magnetic resonance imaging is a valuable troubleshooting tool when sonography is equivocal or inconclusive before therapy or intervention. Early diagnosis by sonography directs therapy and improves outcomes by allowing preservation of the uterus and future fertility. We review the imaging features, differential diagnosis, complications, and treatment of cesarean scar pregnancies in the first trimester.

This study found that asymmetry of 15 dB at 3 kHz on audiometry was associated with higher positive yield on use of MRI in evaluating patients with ASNHL. We recommend that patients who present with ASNHL with this audiometric characteristic undergo MRI as part of their diagnostic workup.

We report a case of an abandoned abdominal ventriculoperitoneal shunt that migrated into the gastric antrum, colonic hepatic flexure, and liver parenchyma, which was discovered incidentally on an abdominal CT obtained for renal stones. In regards to the migrated abandoned VP shunt, the patient was asymptomatic. Upon review of prior CT scans, these findings had progressed over approximately 7 years. We describe the case and discuss the clinical and radiologic findings, complications resulting from ventriculoperitoneal shunts, and possible approaches to their management.
