RESUMEN
Intrasphenoid internal carotid artery (ICA) pseudoaneurysm can present as and mimic a sinonasal mass. The purpose of this review is to describe the computed tomography (CT) and magnetic resonance imaging (MRI) features that should prompt the radiologist to consider this lesion in the differential diagnosis of a skull base mass. Specifically, when a sphenoid mass appears hyperdense, expansile, and destructive on CT and has mixed T1 signal and/or flow-related artefacts on MRI, the differential diagnosis should include a pseudoaneurysm. Vascular imaging is warranted to confirm the diagnosis.

Structured reporting has many advantages over conventional narrative reporting and has been advocated for standard usage by radiologic societies and literature. Traditional structured reports though are often not tailored to the appropriate clinical situation, are generic, and can be overly constraining. Contextual reporting is an alternative method of structured reporting that is specifically related to the disease or examination indication. Herein, we create a library of 50 contextual structured reports for neuroradiologists and emphasize their clinical value over noncontextual structured reporting. These templates are located in the On-line Appendix, and a downloadable PowerScribe 360 file may be accessed at https://drive.google.com/open?id=1AlPUmfAXPzjkMFcHf7vGKF4Q-vIdpflT.

A 7-year-old boy presented with angle-closure glaucoma, initially presumed to be idiopathic. A ciliary body mass was later detected on MR imaging, suggestive of medulloepithelioma but pathologically proved to be diffuse infiltrating retinoblastoma. We discuss the patient management and review the literature, with emphasis on the role of CT and MR imaging in evaluating pediatric angle-closure glaucoma and in influencing the management of patients with retinoblastoma and medulloepithelioma.
