BACKGROUND: Intracranial dermoid cysts (DCs) represent an infrequent subset of congenital ectodermal inclusion cysts predominantly observed near the midline structures. In spite of their benign nature, they can cause clinical manifestations, necessitating surgical removal as the main therapeutic measure.

CASE REPORT: We present here an extremely rare case characterized by a radiologically atypical dermoid cyst located within the corpus callosum, an extremely rare location for such tumors. Successful surgical excision resulted in good clinical outcomes.

CONCLUSIONS: This paper underscores the importance of a timely, proper radiological diagnostic process, which sees magnetic resonance imaging (MRI) as the main step, as well as the fact that interpretation of MRI data can sometimes be challenging, as it was in the patient of this report.
