Corpus Callosum Lipomas in Children

Özet

AIM: To determine the clinical and radiographical aspects of six patients diagnosed with pericallosal lipomas (PCL).MATERIAL and METHODS: A retrospective analysis of patients who presented to the neurosurgery outpatient clinics of SelcukFaculty of Medicine between 2009 and 2019, revealed that six patients were diagnosed with PCL. The clinical and magneticresonance imaging (MRI) data were obtained by reviewing patients’ records.RESULTS: A total of six patients (two girls and four boys), with a mean age of 53.8 months (38–72 months), were included in thisstudy. They were followed up for a mean period of 36.5 months (32–41 months). PCL were detected on MRIs, which were obtainedto investigate headache in two patients, epilepsy in one patient, frontal dermal sinus tract and left frontal epidermoid tumor in onepatient, and subcutaneous lipoma associated with PCL in one patient. Five patients displayed tubulonodular lipomas and onepatient displayed curvilinear lipomas. Agenesis or dysgenesis of the corpus callosum (CC) was observed in four (66%) patients. Twopatients received surgical treatment for cosmetic skin problem.CONCLUSION: Because of the benign course of PCL, i.e. no growth or very slow growth, and close proximity to the surroundingneurovascular structures, surgical removal should be considered only in symptomatic PCL. Furthermore, other malformations andanomalies may accompany PCL.
