The Sneddon's syndrome consists of neurologic manifestations associated to the presence of livedo reticularis and cyanosis of the extremities. The pathological process is an endothelial obliteration of arterioles, leading to a reticular appearance of the skin, despite the environment temperature. The authors present three new cases, caucasian males with 7, 16 and 54 years of age. The youngest started with hemilateralized motor seizures and showed a porencefalic area in the CT scan. The oldest had livedo reticularis, acrocyanosis and started with hemilateralized motor seizures, and a hemiparesis as sequela; CT scan with parasagittal infarct and occlusion presented of one anterior cerebral artery on angiography. The third patient started with hemifacial seizures, developed a labioglossolaringeal paresis and dysarthria as sequela; CT scan and MRI showed multiple infarcts, with multiple occlusions of cortical branches on angiography. The skin biopsies showed endothelial vascular hyperplasia in all cases. Only one (54 years old) patient had a positive IgG antiphospholipid antibodies. The Sneddon's syndrome seems not to be so rare and have to be considered in the etiological investigation of cerebral infarcts, mainly in young people.

A 37-year-old woman with increasing dyspnoea over several months suddenly developed severe ortho- and tachypnoea as well as cyanosis of the lips and acrocyanosis. Pulmonary angiography revealed massive bilateral pulmonary emboli with a systolic pulmonary artery pressure of 75 mm Hg. Phlebography demonstrated a thrombotic occlusion of the deep veins of the left leg extending to the distal femoral vein. Thrombolysis treatment was started via an indwelling pulmonary artery catheter (500,000 IU urokinase and 10,000 IU heparin as bolus, then 1 mill. IU urokinase and 1,000 IU heparin per hour). After two hours an incomplete left-sided paresis occurred (involving ocular and facial muscles, dysarthria, left arm and left leg) and the thrombolytic infusion was stopped. But cerebral computed tomography (CT) did not demonstrate any intracerebral haemorrhage. The heparin infusion was restarted (partial thromboplastin time between 70 and 90 s). CT examinations during the next few days showed the development of an ischaemic infarction in the distribution of the right medial cerebral artery. Angiography demonstrated occlusion of the right internal carotid artery. The diagnosis of a paradoxical embolus was supported by easy cardiac catheter passage through a patent foramen ovale. Subsequent pulmonary angiography demonstrated a thrombus-free pulmonary arterial circulation with a normal pulmonary arterial pressure. There was gradual and extensive regression of the incomplete hemiparesis.

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.
