Objective: To summarize the Magnetic Resonance Imaging (MRI) performance and clinical characteristics of children mild encephalitis with reversible isolated corpus callosum pressure (MERS), and analyze the possible etiology. Methods: The clinical data and MRI findings of 11 children with MERS in children's hospital of Shanxi Province from January 2012 to January 2015 were summarized, and then their clinical manifestations and characteristics were analyzed. Results: Among the 11 patients, 5 were male and 6 were female. The age range was 2- 14 years. Clinical manifestations include fever (7 cases, 63.6%), gastrointestinal symptoms (9 cases, 81.8%), drowsiness (5 cases, 45.5%), convulsions (6 cases, 54.5%), dizziness (2 cases, 18.2%), cervical positive resistance (1 case, 9.1%), carotid resistance suspicious (3 patients [27.3%]). The appearance of cerebrospinal fluid, white blood cell count, leukocyte classification, protein, glucose and chloride are all normal. MRI showed only abnormal signal in the corpus callosum pressure: a slightly longer T1 signal, a longer T2 signal, a high Diffusion Weighted Imaging (DWI) signal, and a low signal of Apparent Diffusion Coefficient (ADC). Has 4 cases of nuclear magnetic head of abnormal signal in the middle of corpus callosum and ovoid, 6 cases, in the middle and a wide belt of corpus callosum, 1 case was located in the corpus callosum and diffuse wide strip. Eleven children were treated with anti-infective agents and other symptomatic treatment. All of the 11 children were recovered and discharged. The duration of the course is 8 d and the longest is 21 d. The results of MRI follow - up showed that the callosal pressure lesion disappeared. Conclusion: The clinical manifestations of children's MERS include fever, gastrointestinal symptoms, drowsiness and convulsions, and their characteristic head MRI is a reversible cytotoxic edema with good prognosis.
