Ethylmalonic encephalopathy (EE) is a rare metabolic disorder with an autosomal recessive mode of inheritance that is clinically characterized by neuromotor delay, hyperlactic acidemia, recurrent petechiae, orthostatic acrocyanosis, and chronic diarrhea. Increased urinary levels of ethylmalonic acid and methylsuccinic acid are the main biochemical features of the disorder. We report on two patients affected by EE who showed different clinical and neuroradiological patterns. Patient 1 presented with a chronic clinical course characterized by very slow neuromotor deterioration, ataxia, and dysarthria. In contrast, patient 2 had an acute neonatal onset with severe neuromotor retardation, severe generalized hypotonia, and intractable seizures. Neuroradiological follow-up of patient 1 detected a diffuse hyperintensity on the T2 images at the basal ganglia which remained stable during a period of four years. Patient 2, in contrast, showed a rapid process of cerebral, and in part, cerebellar atrophy. On the basis of our observations, we reviewed the data published in the literature and tried to delineate the natural history of EE, which appears to be characterized by a wide spectrum of severity in the clinical course. No reports on neuroradiological follow-up of EE patients are available in the literature with which to compare our data. Finally, both patients showed a muscle COX deficiency. The pathogenetic implications of such a biochemical finding will be also discussed.

Thrombotic thrombocytopenic purpura (TTP) is a hematologic disease involving the platelet aggregation and resulting in hemolytic anemia, thrombocytopenia, and microvascular occlusion. Although frequent neurologic features are headache and confusion, focal deficit is described in 30% of the cases. There are a lot of causes inducing thrombotic thrombocytopenic, but reports are lacking when associated with Grave disease. We describe the case of a 51-year-old Caucasian woman presenting a 24-hour story of sudden onset of dysarthria and left superior limb palsy. Four months before, she developed severe hyperthyroidism associated with petechiae, hemolytic anemia, thrombocytopenia, and schistocytes at blood film examination. Relapse of TTP in association with Grave disease was diagnosed. There are few reports describing association between Grave disease and TTP with only mild neurologic involvement. We described, to our knowledge, the first case of acute ischemic stroke secondary to thrombotic thrombocytopenic induced by thyrotoxicosis.
