Value of computed tomographic myelography in neurofibromatosis.

Computed tomographic myelography (CTM) is the procedure of choice in patients exhibiting spinal manifestations of neurofibromatosis. Due to the lack of specificity of several of the more important plain spine radiographic findings in this disease, CTM may be necessary to distinguish between surgical and nonsurgical entities. CTM will determine the size, shape, and intraspinal extension of posterior mediastinal neural tumors and separate them from the more common thoracic meningoceles. CTM will likewise elucidate the causes of posterior vertebral body scalloping, distinguishing between dural ectasia and neural tumor. CTM will also frequently demonstrate additional asymptomatic lesions at other levels.

Arteriography after carotid endarterectomy.

Of 55 patients undergoing carotid endarterectomy, 16 had abnormal postoperative angiograms by accepted literature criteria. Five of the 16 were symptomatic. The other 11 were neurologically stable or improved from their preoperative condition. None of the 16 patients underwent reoperation. Of those 11 who had abnormal postoperative angiograms but a good clinical result, four had a second postoperative angiogram some months later that demonstrated marked improvement in the appearance of the endarterectomy site. Patients undergoing carotid endarterectomy should not be subjected to routine postoperative angiography without clinical indications nor should they undergo reoperation on the basis of angiographic findings alone without consideration of their clinical status.

Quantitative assessment of the lumbar spinal canal by computed tomography.

An experimentally validated simple standardized method for making precise measurements of the spinal canal directly from the video display of a CT scanner is described. Using this method, normal values for anteroposterior diameter, interpediculate distance, and cross-sectional area of the lumbar spinal canal have been determined in a series of 60 adults. A careful study of canal configuration combined with the prudent use of the normal values should allow the CT diagnosis of lumbar spinal stenosis to be made with a high level of confidence.

Peripheral contrast enhancement in chronic epidural hematomas.

Three cases of chronic epidural hematomas with contrast enhanced margins on computed tomography (CT) are presented. The CT findings in epidural hematoma are discussed, and two possible mechanisms for the enhancing margin of the chronic epidural hematoma are suggested.

Intradural herniation of lumbar intervertebral discs.

A case of intradural rupture of a lumbar intervertebral disc is reported, and the literature is reviewed. The majority of intradural disc herniations occur at the L4--5 level. These patients usually have neurologic deficits more severe than those found in the much more common extradural disc herniations. The myelographic picture varies from an irregularly marginated intradural lesion overlying the disc space to a complete block. The common factor allowing intradural disc herniation is probably dense adhesions between the dura and the posterior longitudinal ligament, preventing the more common lateral extradural disc herniation. Intradural disc herniation should be included in the differential diagnosis of lumbar intradural lesions causing nerve root or cauda equina compression.

Contrast agents for myelography: clinical and radiological evaluation of Amipaque and Pantopaque.

The diagnostic quality and side effects of Amipaque and Pantopaque as myelographic contrast agents were compared prospectively using the identical protocol in 167 cases (117 Amipaque, 50 Pantopaque). Good ratings were attained in 74% of Amipaque and 76% of Pantopaque examinations. Demonstration of nerve rootlets in the cauda equina and filling of lumbar root sleeves were superior with Amipaque. Amipaque more easily demonstrated the high posterior cervical subarachnoid space and the anterior and posterior margins of the cervical spinal cord. The incidence of postmyelographic headache was 38% with Amipaque and 32% with Pantopaque. Nausea and vomiting were more common with Amipaque. Two patients experienced grand mal seizures after examination sith Amipaque.

Meningiomas causing spontaneous intracranial hematomas.

Four cases of spontaneous intracranial hematomas caused by unsuspected meningiomas are reported. Nine previous cases were found in the literature and the entire series of 13 cases is reviewed. Because of their unusual clinical presentation, these cases were not diagnosed correctly prior to radiological studies. Hypertension, trauma, and blood dyscrasia played no significant pathogenetic role. The histological features of these hemorrhagic meningiomas are described, and the importance of adequate radiological investigations and early radical surgery is stressed.

Angiographic diagnosis of intra- and extraaxial tumors in the cerebellopontine angle.

Angiography is an effective diagnostic modality in the evaluation of patients with suspected cerebellopontine angle tumor, particularly when there is not a clear clinical differentiation between an intraaxial and an extraaxial mass, or when the patient presents with increased intracranial pressure. In a series of 17 extraaxial masses in the cerebellopontine angle and 2 cerebellar tumors which presented into the angle, the most common angiographic findings were: 1. elevation and/or medial displacement of the proximal portions of the superior cerebellar artery; this finding was seen only in the extraaxial tumors and has not been demonstrated with intraaxial masses; 2. downward, medial, and posterior displacement of the proximal portions of the posterior inferior cerebellar artery; 3. lateral displacement and stretching of the hemispheric branches of both the superior cerebellar and posterior inferior cerebellar arteries; and 4. displacement of the vein of the lateral recess and of the petrosal vein either downward and medially or upward and laterally.
