Abstract
The medical records, CT, and MRI of ten children with trilateral retinoblastoma were reviewed. The intracranial pathology consisted of eight pineal neoplasms and two parasellar lesions, at least seven of the which were calcified. Two lesions demonstrated calcification only (no soft tissue mass) at initial presentation. Hydrocephalus was seen in eight cases, and concurrent or subsequent subarachnoid dissemination was documented in seven. Only one patient is known to be alive at the present time. The imaging features of the midline intracranial tumors mirror those of the ocular neoplasm. As calcification may be the only clue to the presence of the intracranial malignancy, close surveillance of high-risk patients with retinoblastoma with initial CT and follow-up MRI is suggested.
