Agenesis of the corpus callosum: female monozygotic triplets. Case report.

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 etiology and pathogenesis of corpus callosum agenesis are discussed. In this case, unequal X-inactivation as related to the twinning process is implicated as the cause of the agenesis.

Tuberculoma presenting as an en plaque meningioma. Case report.

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.

Burr hole neuroendoscopic fenestration of quadrigeminal cistern arachnoid cyst: technical case report.

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 neuroendoscopic management of these cysts is described.

Cavernous angioma of the upper cervical spinal cord. A case report.

STUDY DESIGN: The treatment of a patient with progressive neurologic deficit secondary to a cavernous angioma located in the dorsal midline of the upper-most cervical spinal cord was described. OBJECTIVES: An illustrative case of a patient with an exophytic cavernous angioma of the cervical spinal cord near the cervicomedullary junction was presented, the literature reviewed, and the treatment of these patients discussed. SUMMARY OF BACKGROUND DATA: Cavernous angiomas of the spinal cord were rarely seen, and only more recently appreciated with the advent of MRI scanning. These lesions were usually intramedullary in location. Intradural extramedullary cavernous angiomas, or intramedullary lesions with exophytic extramedullary extension, were particularly rare and usually occurred at the cauda equina. METHODS: The surgical treatment of a patient with an exophytic cavernous angioma of the upper cervical spinal cord was presented. RESULTS: This patient underwent surgery after a hemorrhage that occurred after the patient was treated conservatively for several years. The entire lesion was resected with standard microsurgical technique, and the neurologic symptoms subsequently resolved. CONCLUSIONS: This entity should be suspected in the differential diagnosis of patients with progressive and step-wise deterioration of spinal cord function. Although these patients can be treated conservatively, those with progressive neurologic deficits should undergo microsurgical resection to avert subsequent lesion enlargement or repeated hemorrhage.

Anatomical progression of the Chiari II malformation.

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) and this ratio was compared on serial MRI scans. Eighteen children had an increase in the B/A ratio, two children had a decrease, and two had no change. This indicates that continuous anatomic change of the Chiari II malformation and the skull base is occurring. Clinical deterioration in the older child may be explained by a combination of compressive and traction forces due to this change.

Scalp and calvarial masses of infants and children.

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 was located over the sagittal suture. Seventeen per cent of the "lumps" had significant intracranial extension. An additional 20% of the lumps extended intracranially, but only to the dura mater. Work-up of these lesions should include initial plain skull roentgenograms to assess multiplicity and appropriate computed tomographic scans to assess possible intracranial extension.

Pediatric spinal injury: the very young.

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 children with traumatic spinal cord injury averaged 6.9 years of age and included 20 girls (43%). The etiology of the pediatric injuries differed from that of adult injuries in that falls were the most common causative factor (38%) followed by automobile-related injuries (20%). Ten children (21.3%) had spinal cord injury without radiographic abnormality (SCIWORA), whereas 27 (57%) had evidence of neurological injury. Complete neurological injury was seen in 19% of all traumatic pediatric spinal cord injuries and in 40% of those with SCIWORA. The most frequent level of spinal injury was C-2 (27%, 15 cases) followed by T-10 (13%, seven cases). Upon statistical examination of the data, a subpopulation of children aged 3 years or younger emerged. These very young children had a significant difference in level of injury, requirement for surgical stability, and sex distribution compared to 4- to 12-year-old children.

Pneumocephalus in patients with CSF shunts.

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 patients, thinned cerebrospinal fluid barriers secondary to long-standing increased intracranial pressure may predispose them to pneumocephalus. Temporary extraventricular drainage is an effective method of treatment in this group of patients. Two other etiologies are identified with significance to treatment, and the role of craniotomy is discussed.

Pediatric axis fractures: early halo immobilization, management and outcome.

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 with the halo alone, and 20% went on to fuse after surgery. The average hospitalization for isolated C-2 injury was 10.6 days. Minor complications occurred in 46% of the patients. The literature is reviewed as to the management and outcome of pediatric axis fractures.
