1 3/4 year old boy with torticollis since birth. Now worsening ataxia and screaming episodes.  

Brain tumors which are diagnosed before the 2nd year, one presumes that they are congenital.
This is possibly the case with this child, since the symptoms exist since birth.
The astrocytoma is the most frequent tumor in childhood. 60 % of them are infratentorial.  

Extensive, mostly cystic, partly solid infratentorial brain tumor with consecutive occlusion hydrocephalus and signs of intracranial pressure.

MRI 1: T2 weighted sequences with signal intense tumor and perifocal edema intracerebellar.

MRI 2: FLAIR with partly signal intense and partly almost liquor intense tumor areas cerebellar. The IV. ventricle is occluded.

MRI 3: T1 weighted image with hypointense tumor.

MRI 4: T1 weighted image with contrast. Partly contrast enhancement in the solid areas and in the margins of the cysts.

Good prognosis since this tumor has WHO grade I and rarely tends to spread liquorgenically.
