This second volume in the Case Review series focuses on the very challenging aspect of Brain Imaging, a distinct subspecialty area of radiology and of neuroradiology, and is perfectly customized to meet the self testing needs of those preparing for the exams. Dr. Laurie A. Loevner, a very talented teacher and enthusiastic radiologist, addresses the congenital, vascular, degenerative, neoplastic, inflammatory, and metabolic diseases that affect the brain. Her well written commentary leads to an in depth discussion and understanding of neurologic disease. This volume coupled with the recently published Head and Neck volume and the soon to be published volume on the Spine, provides an outstanding review of the subspecialty of neuroradiology. Two hundred unknownbrain cases with approximately 420 state-of-the-art images are succinctly presented in random order with questions, answers, commentary, references, and cross-references to Neuroradiology:: THE REQUISITES. Differential diagnoses and pertinent radiologicalfindings are emphasized, but relevant clinical points also are covered. Cases are divided by difficulty level, with a division between more common and the more unusual and challenging cases.
