Neuroimaging Patterns of Intracranial Infections: Meningitis, Cerebritis, and Their Complications

Institute

Neuroimaging plays a crucial role in diagnosing, managing, and monitoring central nervous system (CNS) infections. This review details how various imaging modalities, including CT, MRI, MRS, DWI, PET, and AI, can confirm clinical suspicion, differentiate from mimics, and assess complications like abscess, ventriculitis, and hydrocephalus. It covers classic imaging findings for acute and chronic meningitis, as well as cerebritis, emphasizing the importance of integrating radiographic and clinical information for accurate diagnosis.
