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…

Lymph nodes status is an important predictor of prognosis in head and neck squamous cell carcinoma, making accurate staging critical. The physical examination of the neck is highly inaccurate. CT,…
Thyroid cancer includes several neoplasms originating from the thyroid gland—from indolent and curable histologies of differentiated thyroid carcinoma to aggressive anaplastic thyroid carcinoma. Differentiation of thyroid nodules is problematic on…
The major salivary glands consist of the parotid, submandibular, and sublingual glands. Most neoplasms in other subsites in the head and neck are squamous cell carcinoma, but tumors of the…
