The aim of the present study was to describe the clinical features and to evaluate the surgical treatment outcomes of pediatric patients with cerebral cavernous malformations (CCM). We investigated 85 children (53 boys and 32 girls), aged from 6 months to 17.9 years with CCM. Seizures and symptomatic hemorrhages, which were the most frequent symptoms, occurred in 81 patients. Nine patients had a positive family history of CCM. Eighty patients underwent microsurgical treatment after strict operative indications were met. Neuronavigation, combined with intraoperative ultrasonography or functional MRI, was used for precise localization of the lesions. The principles of minimally invasive techniques were followed during surgery. A total of 89 lesions were removed in 80 patients, and there were no deaths. During their hospital stay, only nine patients suffered from postoperative seizures, which were controlled with medication. Postoperative neurological deficits improved in 27 patients, were unchanged in nine, and worsened in two. With the help of advanced neuroimaging, a satisfactory surgical outcome was achieved for 10 lesions located in eloquent brain areas and four lesions in the brain stem. A follow-up study of 66 patients showed that all of these patients remained seizure-free, and nine patients with postoperative neurological deficits gradually recovered. Microsurgical treatment should be performed early for pediatric patients with CCM. Accurate localization of the lesions and the use of minimally invasive techniques and functional MRI monitoring were the key features of the surgical procedures.
