Maturity of the spine and spine-supporting structures is an important variable distinguishing spinal cord injuries in children from those in adults. Clinical data are presented from 71 children aged 12 years or younger who constituted 2.7% of 2598 spinal cord-injured patients admitted to the authors' institutions from June, 1972, to June, 1986. The 47(More)
Pediatric C-2 fractures have been managed with initial cranial skeletal tong traction or a period of bed rest for reduction and alignment followed by external and/or surgical stabilization. Thirteen children were managed with early halo orthosis to provide the initial reduction/alignment and to accomplish long-term stabilization. Eighty percent had fusion(More)
To evaluate whether anatomic change of the relationship of the Chiari II malformation and the cranial base was occurring, 22 children with meningomyelocele had serial MRI scans reviewed. A ratio (B/A) was established between the distance from the foramen magnum to the caudalmost portion of herniated cerebellum (B) and the diameter of the foramen magnum (A)(More)
Arachnoid cysts of the quadrigeminal cistern have been managed by cyst shunting and craniotomy with cyst fenestration. Two children are presented who underwent successful burr hole neuroendoscopic fenestration of symptomatic quadrigeminal plate cysts. The literature is reviewed with regard to the treatment of quadrigeminal arachnoid cysts, and the(More)
Intracranial tuberculomas generally present as either solitary or multiple lesions in the brain parenchyma. They are characterized by a ring-enhancing area on either computerized tomography scans or magnetic resonance images. A case is presented in which an intracranial tuberculoma was dural based and had an appearance similar to an en plaque meningioma.
The authors present two cases of pneumocephalus occurring in patients with permanent shunts and review nine previously reported cases. Mental status changes and headache are the most common presenting symptoms. Six of the 11 cases of pneumocephalus occurred in patients with shunt placement for hydrocephalus secondary to aqueductal stenosis. In these(More)
A case of identical (monozygotic) triplets, two of whom have agenesis of the corpus callosum, is presented. Prenatal ultrasonography and magnetic resonance imaging revealed two of the triplets to have agenesis of the corpus callosum and the third triplet to have an intact corpus callosum. No such case has been reported in the literature. Theories of the(More)
Review of 70 children presenting with a solitary nontraumatic lump on the head revealed that 61% of the lesions were dermoid tumor, 9% were cephalhematoma deformans, 7% were eosinophilic granuloma, and 4% were occult meningoceles and encephaloceles. Most of the dermoid cysts occurred along sutural lines, but some did not. One of the eosinophilic granulomas(More)
Three cases of ossification of the falx cerebri initially mistaken for vascular lesions based on their magnetic resonance (MR) appearance are reviewed. The MR imaging and computerized tomography characteristics of mineralization of the falx cerebri and their differentiation from interhemispheric vascular lesions are discussed.
