Traumatic chiasmal syndrome associated with midline basilar skull fractures.

We studied two young males who had visual field defects consistent with optic chiasmal injury after blunt frontal head trauma. One patient also had a unilateral optic neuropathy. Long-term follow-up disclosed complete bi-temporal hemianopsias in these patients. Both patients had midline basilar skull fractures that traversed the midclivus through the sella turcica floor, dorsum sellae, and sphenoid sinus. Magnetic resonance images did not identify intrachiasmal hemorrhage as the cause of the visual field defect. We believe this fracture pattern, in conjunction with the magnetic resonance image findings, suggests tearing of the optic chiasm on a microscopic, if not macroscopic, scale as the cause of the complete bitemporal hemianopsia.

Cribside neurosonography: real-time sonography for intracranial investigation of the neonate.

A prospective study was made of 94 real-time sonographic sector scans of 56 neonates in a 6 month period. The examinations were performed using the anterior fontanelle as an acoustic window. In 17 cases, computed tomography (CT) head scans were available for comparison. In no case did the CT and sonographic examination disagree as to the size of the lateral ventricles. Abnormalities detected by sonography include ventriculomegaly, intracerebral hematomas, a congenital glioma, and several cystic lesions. Sonographic sector scanning produces excellent, detailed images of dilated lateral and third ventricles, uses no ionizing radiation, is less expensive than CT, and can be performed in the isolette, minimizing the risk of hypoxia and hypothermia. At Methodist Hospital Graduate Medical Center, sonography has replaced CT as the initial method of investigation of ventricular size. CT plays a complementary role in the evaluation of the posterior fossa, intracranial hemorrhage, and mass lesions.

Ventricular size after shunting for idiopathic normal pressure hydrocephalus.

It has been presumed that idiopathic normal pressure hydrocephalus is due to obstruction. We visualized the ventricles in 19 patients subsequent to shunting. We found no consistent relationship between clinical improvement after shunting and reduction in ventricular size. This suggests that the positive effect of shunting in at least some instances is due to some other factor than reduced ventricular size.

Concurrent intracranial and spinal cord arteriovenous malformations. Case report.

The authors report the case of a patient with subarachnoid hemorrhage in whom an intracranial dural arteriovenous malformation coexisted with a spinal arteriovenous malformation. The latter was considered to be the source of the hemorrhage by clinical and radiographic criteria. It is concluded that patients with subarachnoid hemorrhage who show no suitable intracranial source for their bleed in some instances should be investigated for a spinal origin of hemorrhage.

Magnetic resonance evaluation of pediatric spinal dysraphism.

Magnetic resonance (MR) scans of 22 children with spinal dysraphism were reviewed. MR scans of the cervicothoracic spine in 12 cases revealed 10 Chiari II malformations, 1 Chiari III malformations, and 4 syringohydromyelias. Twelve MR scans of the lumbosacral region were performed demonstrating 11 tethered cords, 6 myelomeningoceles, 4 lipomyeloschises, 2 diastematomyelias, 2 syringohydromyelias, and 2 dermal sinus tracts. MR is effective in defining the relationship of the cerebellar tonsils and brainstem to the upper cervical spinal canal and in evaluating the extent of syringohydromyelia and the degree of cord expansion. The ability to image the spinal cord and associated paraspinal lesions directly in the sagittal and coronal planes with excellent tissue characterization allows MR to accurately diagnose and define the myriad abnormalities associated with pediatric dysraphism.
