ExpertDDx: Brain and Spine,3/e > Neurosugery

Designed with the busy practitioner in mind, ExpertDDx: Brain and Spine, third edition, quickly guides you to the most likely differential diagnoses based on key imaging findings and clinical information. This superbly illustrated resource covers more than 275 of the top differential diagnoses across a broad spectrum of central nervous system diseases, presenting parallel groups of anatomically based differentials, generic imaging patterns, modality-specific findings, and clinically based differentials for each area. Now fully revised and up-to-date, this practical reference clearly guides you through useful, actionable differential diagnoses that lead to definitive findings in every area of the brain and spine.

Key Features

Presents multiple clear, sharp, succinctly annotated images for each diagnosis; a list of diagnostic possibilities sorted as common, less common, and rare but significant; and brief, bulleted text offering helpful diagnostic clues
Reflects changes in 2021 WHO CNS tumor grading and nomenclature
Contains newly identified entities, new differential diagnoses, and updated references
Shows both typical and variant manifestations of each possible diagnosis
Includes more than 7,000 high-quality print and online images  
Features updated genetic information now available in Online Mendelian Inheritance in Man (OMIM)
Separates adult and pediatric DDx lists for even faster reference
Assists you in building either a definitive diagnosis from an imaging study or a carefully refined list of reasonable differential diagnoses
Includes an eBook version that enables you to access all text, figures, and references, with the ability to search, customize your content, make notes and highlights, and have content read aloud
