[CNS tumors of the perinatal period (author's transl)].

23.4% of CNS tumors which occur during the first year of life show a close time relationship to the perinatal period. These tumors are subdivided in 3 groups: neoplasm in stillbirths, those with histological verification in the first week of life, and those with symptoms since the first week of life and later on performed histological investigation. Most of the intracranial tumors are localized supratentorially. Teratomas predominate, their relative frequency decreases with increasing age. 36.2% of the spinal tumors in infancy are time-related to the perinatal period, most of them are lipomas.
