Behavioral disinhibition following corpus callosotomy done for colloid cyst excision in 15-year-old girl: A case report and literature review

BACKGROUND: There is a growing body of literature suggesting that the corpus callosum plays an important role in behavior. While behavioral deficits are a rare complication following callosotomy, they are well-documented in agenesis of the corpus callosum (AgCC), with emerging evidence reporting disinhibition among children with AgCC. CASE DESCRIPTION: A 15-year-old girl had undergone a right frontal craniotomy and excision of a third ventricle colloid cyst using the transcallosal approach. Ten days after the operation, she was readmitted for progressive symptoms of behavioral disinhibition. Postoperative magnetic resonance imaging of the brain showed mild-to-moderate bilateral edematous changes along the operative bed, with no other significant findings. CONCLUSION: To the best of the authors’ knowledge, this is the first report in literature to describe behavioral disinhibition occurring as a sequelae to a surgical procedure involving callosotomy.
