title: Expanded cavum septi pellucidi and cavum vergae associated with behavioral symptoms relieved by a stereotactic procedure: case report.
abstract: METHODS
  A 6-year-old boy had symptoms such as unstable gait, behavioral symptoms, and irregular appetite, evacuation, and sleep. Giant cavum septi pellucidi and cavum vergae of 3 x 3 x 5 cm were revealed by computed tomography (CT) and magnetic resonance imaging (MRI). After stereotactic cyst-peritoneal shunting, regression of the cavities was revealed by CT and MRI, in association with marked improvement in the above-described symptoms. In the corpus callosum particularly, which had been preoperatively revealed on sagittal MRI sections to be extended circumferentially as a result of compression by a cyst; the compression was relieved postoperatively, and compression of the pericallosal brain tissue was also relieved.
  
  
  CONCLUSIONS
  Compression of the brain tissue around the cyst (limbic system, etc.) was considered the most important cause of the behavioral symptoms in this patient.
