Case ReportsThe utility of resuscitative endovascular balloon occlusion of the aorta for temporary hemostasis after extensive bilateral lower extremity injuries: A case report.
A 75-year-old pedestrian was struck by a truck and in shock with both lower extremities significantly deformed, with injuries extending proximally to the inguinal region and degloving injuries. Resuscitative endovascular balloon occlusion of the aorta was performed to achieve temporary hemostasis and the patient became hemodynamically stable. Following stabilization, both lower extremities were amputated. Resuscitative endovascular balloon occlusion of the aorta may be effective to achieve temporary hemostasis in patients with extensive injuries of the lower extremities, especially with extension to the inguinal region which precludes use of a tourniquet.

Case ReportsPosterior fossa choroid plexus papilloma with focal ependymal differentiation in an adult patient: A case report and literature review.
Choroid plexus papillomas (CPPs) are rare neoplasms classified as World Health Organization grade I tumors. CPPs containing other tissues have occasionally been documented in the literature. However, few of these previous reports have provided clinical and radiological information. ⋯ Immunohistochemical staining of glial fibrillary acidic protein was focally positive around the capillaries, which was suggestive of "perivascular pseudorosette" formation. Our case showed similar imaging appearances as those of CPP; thus, it seems difficult to distinguish CPP with versus without ependymal differentiation by clinical and radiological features alone. The clinical significance and pathogenesis of ependymal differentiation in CPP remain unclear, and further case reports are required.

Cesarean scar ectopic pregnancies are a rare form of extrauterine pregnancies, yet their incidence is increasing given the rise in cesarean deliveries. Similar to other ectopic pregnancies, cesarean scar ectopic pregnancies pose a great risk for maternal hemorrhage and ultimately maternal mortality. This study presents the case of a cesarean scar ectopic pregnancy in a patient with 3 prior cesarean deliveries. Here, we highlight the importance of early diagnosis and treatment of cesarean scar ectopic pregnancies.

Case ReportsLoop formation by an aortic occlusion balloon catheter during resuscitative endovascular balloon occlusion of the aorta (REBOA).
A 77-year-old man was transferred to our hospital for endoscopically uncontrollable active bleeding from a duodenal ulcer. Soon after his arrival, he became hemodynamically unstable and resuscitative endovascular balloon occlusion of the aorta was performed using a 7-F aortic occlusion balloon catheter (Rescue Balloon; Tokai Medical Products, Aichi, Japan). ⋯ CT demonstrated that the distal part of the catheter shaft had made a loop in the aorta and the balloon was located at the level of the upper abdomen. We consider the low-profile occlusion balloon catheter to be less rigid than large ones, and care should be taken to prevent balloon migration and catheter shaft bending.

Case ReportsPerforated cecal diverticulitis with CT diagnosis and medical management.
Acute diverticulitis is a painful condition of the gastrointestinal tract that results from sudden inflammation of one or more diverticula in the bowel wall. Right-sided acute diverticulitis, such as cecal diverticulitis, is uncommon diagnosis that can be easily misdiagnosed as acute appendicitis as it shares similar clinical presentation. An unusual complication of right-sided acute diverticulitis such as perforated cecal diverticulitis has different management from acute appendicitis. ⋯ We report a case of 43-year-old man who presented to the Emergency Department with acute onset severe right lower quadrant abdominal pain associated with anorexia, fever, and nausea. Computed tomography scans obtained showed findings consistent with perforated diverticulitis limited to the cecum, and normal caliber appendix. Conservative medical treatment was decided based on localized imaging findings with excellent outcome.
