Frontal mucocele with orbital extension: a series of 4 cases and review of the literature

Introduction: Mucoceles are benign tumors developed at the expense of the mucosa of the facial sinuses. They can potentially compromise life and visual function. The aim of this study is to present management, clinical and radiological aspects of 4 cases of mucoceles. Clinical case: These 4 cases are all male with ages ranging from 46 to 54 years old. 3 of them presented exophthalmos without oculomotor disorders. 2 patients performed a computed tomography (CT) showed a frontal sinus mass associated with bone lysis. The mass was revealed on magnetic resonance imaging (MRI) in 2 cases. Excision of the mucocele was performed. Contents were sterile in all patients. Postoperative follow-up was uneventful. Conclusion: Although benign and slow growing, mucoceles can compromise vital and visual prognosis due to their extensions. Management involves otolaryngology and/or neurosurgical interventions.
