This report describes a male infant who presented since birth with rigidity and hypokinesia. Severe developmental delay, episodic central hypoventilation, and drug-resistant epilepsy progressively added to the extrapyramidal signs in the following months and led to the patient's death at 10 months of age. Neuroradiologic and neurometabolic evaluations were negative. Normal cerebrospinal metabolites excluded a defect in dopamine metabolism, and treatment with levodopa failed to improve his motor symptoms. Neuropathologic findings demonstrated dentato-olivary dysplasia. While isolated dentato-olivary dysplasia has been described in a few cases of Ohtahara syndrome, to our knowledge, the association with infantile parkinsonism has not been previously reported.

Polymicrogyria is a heterogeneous malformation of cortical development microscopically defined by an excessive folding of the cortical mantle resulting in small gyri with a fused surface. Polymicrogyria is responsible for a wide range of neurological symptoms (e.g.

Dysplasia of the cerebellar dentate nucleus is a state of apparent maturational arrest that involves the cerebellar dentate nucleus. Origins include Joubert syndrome, other disorders of axon guidance and dentato-olivary dysplasia. An overview is given, linking the diverse etiologies.

We report the autopsy case of a boy with arthrogryposis multiplex congenita, associated with callosal agenesis and dentato-olivary dysplasia. The patient manifested with dysmorphic facial features and suffered from intractable epilepsy during the neonatal period. These sets of complications suggest that a common molecular mechanism may be involved in the development of corpus callosum and the folding of the dentate and inferior olivary nuclei.
