[Unusual symptoms in brain tumors in childhood].

Headache, nausea, ataxia and diplopia are leading symptoms of brain tumors in children. We report of 3 children with unusual symptoms and findings. Patient 1 complained of occasional headaches. Clinical examination showed neurological deficits and uveitis. Lumbar puncture revealed a pleocytosis and the oligoclonal banding study was positive. Cranial MRI demonstrated an enlarged pons. Under treatment with cortisone a clinical improvement was seen, but no change of the abnormalities in MRI. Several weeks later a biopsy was performed, which verified an astrozytoma. The second child developed a torticollis, following an accident, and later a refractory constipation was noted. A clinical evaluation was within normal limits. Several weeks later the patient complained of bladder disturbances. Patient 3 had a lateralized tic disorder without any neurologic deficits. CT showed an infratentorial tumor above the 4th ventricle. The tic disorder vanished only after the tumor was completely resected in the second operation. The reported cases demonstrate the fact that in an individual patient a brain tumor can cause unusual symptoms and findings which do not make the diagnosis obvious.
