We evaluated 17 children with primary intracranial neoplasms for subarachnoid metastatic disease(SAMD)using myelography with computed tomographic follow-up(Myelo+CT)and cerebrospinal fluid(CSF)histopathologic examination as well as magnetic resonance imaging with gadolinium DTPA (MRI+Gd),between December 1988 and December 1989.There were 12 boys,and the median age was 5.7 years(range,0.8 to 21.8 years).Tumor histology included 8 primitive neuroectodermal tumors(PNETs),3 ependymomas,2 low- grade astrocytomas,1 anaplastic astrocytoma,1 glioblastoma multiforme,1 atypical rhabdoid tumor,and 1 malignant fibrous histiocytoma.Thirteen tumors originated in the posterior fossa,2 were supratentorial,and 2 were in the spinal cord.The medial interval between the 2 diagnostic tests was 2 days.MRI+Gd was positive in 11(65%),Myelo+CT in 8(47%),and CSF in 5(29%) cases.MRI+Gd was superior in delineating spinal cord nodules and"sugar coating"whereas Myelo+Ct more readily revealed nerve root sleeve filling defects.There was no case in which Myelo+Ct was positive that MRI+Gd did not reveal SAMD.MRI+Gd is a safe,noninvasive test that should be used as the initial imaging modality for the presence of SAMD. |
