Rasmussen's encephalitis in a pediatric patient with subtle early MRI changes: A case report.

Rasmussen's encephalitis (RE) is a progressive inflammatory neurological process most commonly occurring in children characterized by drug-resistant focal epilepsy, hemiplegia, and cognitive decline, with brain atrophy and white matter changes typically localized to 1 hemisphere of the brain. Because the clinical course of RE is often indistinguishable from a variety of medical conditions, MRI has historically been the primary diagnostic tool. Here, we report both the clinical course and progression of neuroimaging findings of a 5-year-old female who had very subtle early cortical and white matter changes on MRI and was diagnosed with RE by correlating the clinical presentation, imaging, and electrographic findings.

CT screening for lung cancer: value of expert review of initial baseline screenings.

OBJECTIVE. Appropriate radiologic interpretation of screening CT can minimize unnecessary workup and intervention. This is particularly challenging in the baseline round.
