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.
