Intracranial dermoid cysts are benign, slow, extra-axial, benign dysembryoplastic tumors. We report the case of a 29-year-old man who visited emergency rooms for sudden onset headaches. A cerebral CT showed a left basal frontal cyst formation of homogeneous fat density. MRI confirmed the fat content of the cyst and its intraventricular rupture. Histologically, dermoid cysts have a thick wall with possible presence of different appendages of the skin explaining the possibility of rupture during growth, even if rare. Imaging, based on CT and especially MRI, allows the positive diagnosis of this rupture. Conservative treatment may be considered for ruptured cysts where there is a risk of intraoperative vascular involvement, but with a risk of recurrence of rupture.
