Intraspinal Seeding from Intracranial Tumors in Children 805
Cerebrospinal fluid-borne metastases were demonstrated by metrizamide myelography in 20 children with primary intracranial tumors, posterior fossa medulloblastomas being the most common. The lumbosacral region was affected most often, with nerve root thickening, nodularity, and irregularity of the thecal sac. Cord cloaking, nodularity, and meningeal disease were common in the cervical and thora...
متن کاملIntracranial and intraspinal meningeal melanocytosis.
We describe a 35-year-old man with a history of remote closed head injury who presented with new neurologic deficits. A noncontrast head CT scan showed hyperattenuation involving both temporal lobes, frontal lobes, basal meninges, and cerebellum. A subsequent contrast-enhanced MR examination of the brain showed enhancement in the basal cisterns extending into the upper cervical spine and throug...
متن کاملSurgery of intraspinal cord tumors.
Since the pioneer work of Elsberg,10 several authors have greatly contributed to spinal cord surgery, including Cooper,9 Epstein,11 Guidetti,14 McCormick,20 Malis,21 Stein,26–28 and others.2,6,8,12,13 Strategy has been deeply modified, mainly with magnetic resonance imaging (MRI), ultrasonic aspiration, and, recently, with preoperative neurophysiology. But, one should not forget the value of cl...
متن کاملEarly CT detection of intracranial seeding from medulloblastoma.
Since 1975, intracranial subarachnoid metastases of medulloblastoma have been detected in seven of 23 initial contrast-enhanced computed tomographic (CT) scans in children with proven medulloblastoma. Furthermore, four of the seven cases with subarachnoid seeding were diagnosed after the introduction of high-resolution contrast-enhanced CT. Only three cases of seeding had been detected in the p...
متن کاملMagnetic resonance imaging of intracranial tumors in children and adolescents.
Magnetic resonance (MR) scans were reviewed of 25 children and adolescents from the age of 9 months to 18 years referred with a suspected or proven diagnosis of intracranial tumor. Twenty-one of these children had MR scans positive for tumor. Histology was available in 14. The other seven patients were managed clinically as cases of cerebral tumor, although histologic confirmation was lacking. ...
