Arachnoid cysts at the craniovertebral junction are uncommon, and all the reported cases had location posterior to the brain stem. We describe 2 cases of ventral arachnoid cysts among children.
Two children, in their first decades of life, presented with spastic quadriparesis without complaints of raised intracranial pressure. Magnetic resonance imaging showed large, ventrally located cystic lesions compressing the brain stem and extending from posterior fossa to the lower level of C4 vertebra. Both patients underwent surgery via midline posterior fossa approach and fenestration of cysts along with partial excision. Both patients made complete recovery and are asymptomatic in the long-term outcome.
Ventral arachnoid cysts at the craniovertebral junction present in the pediatric age group because of compression of corticospinal tracts. These patients have good long-term outcome after fenestration and partial cyst excision.
颅颈交界区的蛛网膜囊肿并不常见，所有报道的病例均位于脑干后方。我们描述了2例儿童腹侧蛛网膜囊肿病例。
两名儿童，年龄在十几岁，表现为痉挛性四肢瘫，无颅内压升高的主诉。磁共振成像显示大的、位于腹侧的囊性病变压迫脑干，从后颅窝延伸至C4椎体下部水平。两名患者均通过后颅窝中线入路进行手术，囊肿开窗并部分切除。两名患者均完全康复，长期随访无症状。
颅颈交界区腹侧蛛网膜囊肿在儿童年龄组中出现是由于皮质脊髓束受压。这些患者在囊肿开窗和部分切除后长期预后良好。
