The clinical characteristics of children with splenium of corpus callosum solitary lesions displayed on MRI / 中华神经科杂志

ABSTRACT

Objective To explore the prominent clinical features and the prognosis of corpus callosum solitary lesions cases in children.Methods There were 16 cases with corpus callosum solitary lesions receiving treatment at our hospital from January to December 2013.All of the clinical features were collected and retrospectively analyzed.Results The 16 cases aged 1 year to 13 years with an average age of (3.44 ± 3.65) years.The causes of the disease included the viral encephalitis,convulsions,and rotavirus infection.The most prevalent disorders were convulsions (10 cases),gastrointestinal symptoms (8 cases),fever (8 cases),positive cervical resistance (6 cases),fatigue (5 cases),altered states of consciousness (2 cases),headache (1 case),and dizziness (1 case).Corpus callosum lesions lasted for 13-50 days,with an average of (28.8 ± 10.2) days.Cranial magnetic resonance showed the splenium of the corpus callosum with isolated oval lesions,low signal on T1 weighted images and apparent diffusion coefficient images,high signal on T2 weighted images and diffusion weighted images.Conclusions The splenium of the corpus callosum lesions of children occur in a lower rate than adults with the etiology including intracranial infection,convulsions and rotavirus infection.Main clinical manifestations include fever,convulsions and gastrointestinal symptoms (nausea,diarrhea,etc).The cases followed-up showed the lesions and symptoms are reversible,and the prognosis is good.
