Intracranial dermoid cysts are uncommon lesions. They account for <1% of all intracranial masses, with characteristic imaging appearances, they are usually well-defined lobulated midline masses that have low attenuation (fat density) on computed tomography CT and high signal intensity on T1-weighted the magnetic resonance imaging (MRI). Typically they do not enhance after contrast administration. Rupture of intracranial dermoid cysts (RICDC) is a rare phenomenon and in this article we report two additional cases to the literature. The rupture can be traumatic or non-traumatic and CT is often adequate in making a diagnosis of this entity, MRI can complete the characterization showing presence of T1 hyperintense droplets and leptomeningeal enhancement. This complication can be treated surgically or conservatively depending on the clinical symptoms.
