Radiology Key

Radiology provides valuable gross pathologic information about central nervous system (CNS) infections. Major categories of infectious lesions of the brain and spinal cord are recognized by imaging such as diffuse,…

Infection of the central nervous system (CNS) in children is an important entity and early recognition is paramount to avoid long-term brain injury, especially in very young patients. The causal…

Infections of the spine represent a rare but potentially debilitating and neurologically devastating condition for patients. Early diagnosis, imaging, and intervention may prevent some of the more critical complications that…

Infections of the head and neck vary in their clinical course and outcome because of the diversity of organs and anatomic compartments involved. Imaging plays a central role in delineating the anatomic…

Neurocysticercosis (NCC) is an infection of the central nervous system by the Taenia solium larvae, and is the most common cause of acquired epilepsy in endemic regions. The natural history…

Fungal infections of the central nervous system (CNS) frequently occur in the immunocompromised or debilitated host. Imaging findings are non-specific but may be organized into extra-axial, parenchymal, and vascular categories….

Imaging plays an important role in the diagnosis and treatment of brain abscess, pyogenic infection, and encephalitis. The role of CT and MRI in the diagnosis and management of pyogenic brain…

In cases of central nervous system infection, it is crucial for the neuroradiologist to provide an accurate differential diagnosis of the possible pathogens involved so that treating physicians can be…

Image-guided tissue sampling is becoming increasingly important for management of head and neck cancers. Ultrasound-guided fine-needle aspiration (UG-FNA) is safe, effective, and has many advantages compared with palpation-guided FNA and…
