Case Report:
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.
