Mucoceles are uncommon benign pseudocysts characterized by an insidious course. Their association with acute cellulitis is rare and highlights the urgency of appropriate management. We report the case of a 40-year-old patient with no significant medical history, admitted for the management of a frontoethmoidal mucocele causing posterior displacement of the globe, evolving over four months, and complicated by acute inflammation of the left upper eyelid for five days. Orbital computed tomography (CT) revealed a left frontoethmoidal mucocele responsible for sinus expansion with erosion of the orbital roof cortex and orbital extension, leading to posterior displacement of the intraconal contents and resulting in grade I extra-axial exophthalmos.
