MR Imaging of the Cavernous Sinus

Due to its unique location lateral to the pituitary fossa, inferior to the optic chiasm, and encasing cranial nerves III, IV, V1, V2, and VI, the cavernous sinus region has held great interest to the neuro-ophthalmologist. Recent advances in neurosurgical technique allowing microsurgical dissection within the sinus itself make identification and exact location of lesions increasingly important

MR Imaging of the Cavernous Sinus

Due to hs unique location lateral to the phuhary fossa, inferior to the optic chiasm, and encasing cranial nerves Ill, IV, V1, V2, and VI, the cavernous sinus region has held great interest to the neuro-ophthalmologist. Recent ad vances in neurosurgical technique allowing microsurgical dissection within the sinus its~ make Identification and exact location of lesions increasingly important. While dynamic CT scanning has added significantly to the non Invasive evaluation of the cavernous sinus, MR Imaging promises to further enhance our ability to accurately in age the cavernous sinus and its contents. MRI has several obvious advantages, including the absence of radiation, direct multiplanar images, the absence of bone and dental artifact, and the avoidance of iodinated contrast

Eye Pain: A Neurologic Perspective - Primary Headache Disorders

Headache is one of the most common disorders presenting to the physicians office. Epidemiologic studies show that in a given year, the majority of people within the United States will have headache, and approximately 5% will seek medical attention. It is estimated that 25% of all new visits in a neurologists office is for headache. Over 90% of headaches are primary headache disorders that are they have no underlying secondary cause. As physicians, our main concern is finding the underlying disease or disorder that is causing headache. The primary headache disorders by definition have no significant abnormalities on their examination, nor relevant findings on neuroimaging. The key to making a diagnosis in the primary headache disorders taking a thorough history
