Evaluation of sellar and parasellar masses by computed tomography.

Computed tomography is the method of choice for initial evaluation of patients with potential suprasellar masses. In our experience, CT has proved completely reliable for detecting or ruling out the presence of a suprasellar mass, the direction and degree of parasellar extension, and the presence of any calcific or cystic component of the lesion. When multiple cut CT has been negative, further diagnostic studies have proved unrewarding. When CT has been positive, additional studies have been required in some cases to rule out aneurysm prior to craniotomy.

Computed tomography in the diagnosis of extra-axial posterior fossa masses.

Extra-axial posterior fossa masses can be diagnosed reliably by computed tomography (CT) in most cases. Acoustic and trigeminal neurinomas, meningiomas, cholesteatomas, and other extra-axial masses can usually be distinguished from intra-axial masses by asymmetric widening of the basal subarachnoid spaces, bone destruction, continuity of the tumor mass with the tentorium or bone, and more sharply defined margins. Multiple-cut study of the posterior fossa improved visualization of the fourth ventricle and basal cisterns. Interpretation of cisternal changes in association with changes in the fourth ventricle and abnormal attenuation coefficients permits accurate diagnosis of posterior fossa masses.

Spinal neurofibromatosis.

Neurofibromatosis is a congenital abnormality due to maldevelopment of the neurectoderm and mesoderm. Spinal abnormalities are a frequent occurrence and the roentgenological changes observed in 21 patients are presented. These include scoliosis, posterior scalloping of vertebral bodies, and the roentgenological features associated with intraspinal tumors and thoracic meningoceles.
