title: [Infratentorial brain tumors in childhood and adolescence--value of MRT in initial and recurrence diagnosis].
abstract: MRI is the current method of choice for the diagnosis of infratentorial tumors in children and adolescents. The present article discusses the individual tumor entities on the basis of their magnetic resonance imaging characteristics in the patient pool of 1991/1992. New magnetic resonance imaging procedures are considered for infratentorial vascular anomalies. In addition to its use in the primary diagnosis, the significance of MRI for the detection of recurrences is discussed. Problems arising after prior surgery and irradiation as well as metastasization through CSF pathways are also mentioned.
