Abstract

Background: Epilepsy is the main complication of febrile status epilepticus (FSE) in children. The association between FSE and the development of hippocampal sclerosis (HS) and mesial temporal lobe epilepsy (MTLE) is controversial.

Objectives: This study primarily aimed to evaluate the role of magnetic resonance imaging (MRI) in diffusion-weighted imaging (DWI) sequence during the acute phase of FSE in predicting long-term development of HS and epilepsy. The secondary objective was to assess the value of arterial spin labeling (ASL) perfusion MRI in the acute phase of FSE.

Methods and settings: Patients with a first episode of FSE between 6 months and 5 years of age who underwent early MRI were retrospectively included. MRI analysis focused on the DWI signal and the presence of perfusion abnormalities on ASL imaging. We also examined the first electroencephalogram (EEG) during the acute phase. Long-term follow-up analysis assessed the occurrence of HS on MRI scans and the development of epilepsy.

Results: A total of 15 children were included. The presence of restricted diffusion areas on MRIs performed in the acute phase after FSE was significantly associated with the later development of HS. However, the association between restricted diffusion areas on early MRIs and the development of pharmaco-resistant epilepsy on follow-up, found in 3 patients, was not statistically significant. There was a trend for an association between early ASL perfusion MRI changes and EEG findings when both examinations were performed closely.

Conclusion: Early DWI-MRI seems to play a major role in the prognostic evaluation of FSE in children. It may help to determine hippocampal involvement and assess the risk of subsequent HS. However, the study data are insufficient to conclude on the association between diffusion abnormalities and the development of MTLE. Although ASL perfusion may provide additional insight, more data are needed.

期刊介绍： Archives de Pédiatrie publishes in English original Research papers, Review articles, Short communications, Practice guidelines, Editorials and Letters in all fields relevant to pediatrics. Eight issues of Archives de Pédiatrie are released annually, as well as supplementary and special editions to complete these regular issues. All manuscripts submitted to the journal are subjected to peer review by international experts, and must: Be written in excellent English, clear and easy to understand, precise and concise; Bring new, interesting, valid information - and improve clinical care or guide future research; Be solely the work of the author(s) stated; Not have been previously published elsewhere and not be under consideration by another journal; Be in accordance with the journal''s Guide for Authors'' instructions: manuscripts that fail to comply with these rules may be returned to the authors without being reviewed. Under no circumstances does the journal guarantee publication before the editorial board makes its final decision. Archives de Pédiatrie is the official publication of the French Society of Pediatrics.
