IMAGES IN PAEDIATRICS...

摘要

An 8-year-old boy presented with occipital headache, vomiting and severe gait disorder, with inability to walk. A magnetic resonance image of the brain showed hydrocephalus with transependymal resorption (fig 1A) and marked bilateral cerebellar swelling {fig IB) with brainstem compression (fig 1C). Examination of the cerebrospinal fluid showed lymphocytic pleiocytosis. Serological investigations (for herpesviruses, Coxsackie, varicella, Epstein-Barr virus, Borrelia burgdorferi, Mycoplasma) were negative. After treatment with high-dose steroids, the patient improved dramatically within 6 days. Repeated magnetic resonance imaging showed only mild cerebellar atrophy (fig 2A,B)
