case_images: A 34-year-old African male was referred to the otolaryngology clinic for unilateral (right) supraorbital swelling and post-nasal drip (Fig. 1A). At 4 month follow-up visit the patient was completely recovered with open frontal sinus drainage (Fig. 1B).

case_images: Superior wall of the sinus was intact while the frontal sinus floor was eroded and the mass extended into the supero-medial aspect of the orbit (Fig. 2A-B). Then, a contrast-enhanced magnetic resonance (MR) confirmed the diagnosis of a benign fluid-filled lesion (Fig. 2C).
