The diagnosis and treatment of central nervous system fungal infections typically pose problems for the clinician. With an increased incidence of fungal infections in immunocompromised patients, neuroradiologic imaging has become essential in determining complications and outcomes. This article provides a summary of the more common organisms encountered in fungal infections of the central nervous system and the imaging features primarily seen with CT and MR imaging.

Neurocysticercosis produces a variety of neurologic syndromes resulting from the cysticerci infestation of the central nervous system by the larvae of Taenia solium. Because of increased immigration to the United States from endemic areas, the incidence of neurocysticercosis has increased, especially in California, Texas, Arizona, and other southwestern states. Neuroimaging studies play a significant role in the diagnosis and management of patients with neurocysticercosis.

ReviewImaging of rickettsial, spirochetal, and parasitic infections.
This article reviews the clinical signs, symptoms, and neuroimaging findings of the commonly known rickettsial, spirochetal, and parasitic infections (cysticercosis is covered elsewhere in this issue). Differential diagnoses and significant imaging characteristics are reviewed to help narrow the diagnostic possibilities. Several of the infections in this disparate group are not seen as commonly as they once were because of advances in early diagnosis, treatment, improvements in sanitation, and prevention of epidemics. Many of the infections, however, are endemic to certain parts of the world and are seen with increasing frequency in immunocompromised individuals.

A large number of entities can present as a suprasellar or parasellar mass. These include benign and malignant tumors as well as inflammatory and other lesions that can mimic a neoplasm. Imaging features and distinguishing characteristics of juxtasellar masses are described.

The combination of surgery and radiation remains the most effective treatment for tumors affecting the central nervous system. This article reviews surgical therapy for brain tumors. Special attention is paid to new approaches to brain tumor therapy and to the interaction between neuroimaging and successful surgery.
