The case reports of two Swedish girls with initially pseudostationary clinical pictures, one simulating ataxic and the other dyskinetic cerebral palsy, are presented. It was eventually revealed that they had a slowly progressive encephalopathy with pronounced gross motor disability and signs of severe dyskinesia, but only mild intellectual delay. Electron microscopy of skin biopsies showed a picture identical to that in Salla disease. They had a moderately increased 5-10 fold urinary free sialic acid excretion, increased sialidase activity in lymphocytes but normal activity in cultured fibroblasts. These two Swedish cases represent variants of Salla disease, a group of conditions with probable genetic heterogeneity.
