Abstract: Orbital dermoid cyst represents 3 to 4% of all primary orbital tumors. The intraorbital location is relatively
rare and it commonly occurs at childhood. We reported the case of a 4-year-old male child with an
intraorbital dermoid cyst, who presented with progressive left proptosis, which had noticed 6 months earlier.
Visual acuity, ocular motility and fundoscopic examination were normal. Magnetic resonance Imaging
(MRI) revealed an extraconal orbital mass situated on superior & mildly posterior aspect of orbit and which
was iso-to-hypointense in T1, hyperintense in T2, restriction of diffusion in DWI, hyperintense signal on
ADC (Shine through) and no enhancement after giving contrast. The tumor was completely excised via a
left fronto-orbital access. Histopathologically, the tumor was confirmed as dermoid cyst.Keywords: Dermoid cyst, intraorbital, MRI, surgery
