Reversible splenial lesion syndrome (RESLES) is a type of lesion that occurs in the middle splenium of the corpus callosum (SCC), and it is characterized by reversible changes of unknown origin. 1,2 This condition has been associated with both infectious and non-infectious disorders, with reports of cases associated with viruses such as influenza, measles, mumps, rotavirus, adenovirus, Epstein-Barr virus, and herpesvirus 6. 3,4 The most common neurological symptoms of RESLES are encephalitis and encephalopathy while idiopathic intracranial hypertension is a rare complication. [5][6][7] Although severe acute respiratory syndromecoronavirus-2 (SARS-CoV-2) primarily affects the lungs, there have been reports of various neurological complications, such as meningitis, ischemic stroke, encephalitis, and Guillain-Barré syndrome, in patients with coronavirus disease-2019 (COVID-19). 8,9 This article reports on the clinical symptoms of a girl with RESLES who was also found to be positive for SARS-CoV-2. CASE REPORTA 14-year-old girl with no previous medical history presented with symptoms of dizziness, ataxia, and blurred vision for a duration of three weeks. Upon neurological examination, she exhibited confusion and ataxia, but her cranial nerves were intact, and she

BackgroundReversible splenial lesion syndrome (RESLES) is a new clinico-radiological syndrome. We retrospectively analyzed the clinical features of 130 children with RESLES in China, which is the largest case series available in the literature.MethodsThe clinical data of children diagnosed as RESLES in Jiangxi Provincial Children's Hospital between 2017 and 2023 were retrospectively analyzed. The 130 cases were divided into two groups: ≤ 3 years old group (group A) (n = 83) and > 3 years old group (group B) (n = 47). The chi-squared test or Fisher's test was used to evaluate the data.ResultsThe vast majority of patients (127/130 cases, 97.7%) had prodromal symptoms of infection. Preceding infections of the gastrointestinal tract were statistically more significant in group A (60/83, 72.3%) than in group B (11/47, 23.4%) (P < 0.05). Preceding infections of the respiratory tract were statistically more significant in group B (33/47, 70.2%) than in group A (17/83, 20.5%) (P < 0.05). Seizures were statistically more significant in group A (82/83, 98.8%) than in group B (24/47,51.1%) (P < 0.05). The disturbance of consciousness and headache/dizziness were statistically more significant in group B (27/47, 57.4%; 37/47, 78.7%) than in group A (3/83, 3.6%; 1/83, 1.2%), respectively (P < 0.05). Convulsions with mild gastroenteritis (CwG) were statistically more significant in group A (50/83, 60.2%) than in group B (8/47, 17.0%) (P < 0.05). However, encephalitis/encephalopathy was statistically more significant in group B (20/47, 42.6%) than in group A (10/83, 12.0%) (P < 0.05). MRI showed cytotoxic edema in typical locations (RESLES type-1 limited to the splenium of the corpus callosum and RESLES type-2 spread to the entire corpus callosum, adjacent white matter, or both). There was full recovery of the lesions of MRI in all cases from 3 days to 50 days after the initial examinations. All the children showed normal neurodevelopment.ConclusionInfection was the most common cause of RESLES. Infections of the gastrointestinal tract are common in ≤ 3 years old children, while infections of the respiratory tract are common in >3 years old children. Younger patients are more likely to develop convulsions, and older children were more likely to have symptoms with disturbance of consciousness and headache/dizziness. RESLES has characteristic MRI manifestations and a good prognosis.
