Introduction: Sturge-Weber syndrome (SWS) is a neurocutaneous syndrome with typical clinical features including seizures, chronic hemiplegia, hemianopsia and intellectual impairment. Progressive clinical decline may be attributable, at least in part, to progressive venous ischemia. Transcranial Doppler (TCD) ultrasonography could be useful to monitor the degree of hemodynamic involvement and its progression., Purpose: To determine whether there is an association between the degree of asymmetry in TCD and intensity of clinical and radiological involvement and whether there is a correlation between clinical changes and changes in serial TCD., Methods: In fourteen SWS pediatric patients and two "possible cases" (infants younger than two years old without previously known brain involvement, but with other typical signs of SWS) mean flow velocity in the middle cerebral arteries (MCA) was measured by TCD in both hemispheres. The percent difference between hemispheres (asymmetry) was calculated. Clinical and radiological severity was scored using scales. The correlation between TCD asymmetry and SWS clinical and radiological scores was analyzed at baseline, as well as the correlation between the changes in the different variables (TCD asymmetry, clinical and radiological cores) during evolution and in relation to the changes due to therapy., Results: The percentage of MCA velocity asymmetry was positively correlated with the clinical severity score (p = 0.04), and with seizure frequency (p = 0.014). Throughout evolution, therapeutic and clinical changes were associated with noticeable changes in transcranial doppler asymmetry in some cases., Conclusions: TCD may provide a noninvasive method to assess the severity of blood flow abnormalities at baseline and a method to monitor children for progressive changes over time., Competing Interests: Declaration of competing interest None., (Copyright © 2020 European Paediatric Neurology Society.

Hemophagocytic lymphohistiocytosis (HL) is a rare syndrome, although more common in children, that may be underdiagnosed. The clinical presentation can be aggressive, and patients may rapidly develop lethal multiple organ failure....HL simulates the presentation of infectious sepsis, although the response to treatment and evolution are worse. HL should be suspected in young children with persistent fever of unknown origin, general malaise, hepatosplenomegaly, cytopenia, elevated triglycerides and ferritin, and decreased fibrinogen. Brain MRI shows diffuse leptomeningeal and perivascular enhancement, patchy areas of hyperintensity in the white matter of both cerebral hemispheres on T2-weighted sequences, and cerebral atrophy. Diffusion-weighted sequences are useful for staging the lesions. We present a fatal case of familial HL and review the literature about the clinical, histological, and radiological characteristics of this disease., (Copyright 2009 SERAM.
