On examination, there was mild proptosis as evident by visible conjunctiva between the cornea and upper eyelid [Figure 1a]. The lesion extended into the left orbit causing lateral displacement of the left eyeball [Figure 1b]. Marsupialization procedure was carried out draining the contents of the cyst [Figure 1c]. The medial wall of the orbit was found eroded causing the exposure of the eyeball with periorbital fat [Figure 1d]. On 12-month follow-up, there was complete resolution of the symptoms with disappearance of proptosis and diplopia [Figure 1e]. CT scan revealed complete resolution of the cystic mass and normal position of the eyeball [Figure 1f]. Endoscopically, the frontal sinus ostium was found to be patent and fully epithelialized with healthy mucosa [Figure 1g].
