Abstract

Osteoma is the most frequent benign tumor of paranasal sinuses. Usually osteomas are asymptomatic and discovered incidentally during radiological imaging for other reasons. A giant osteoma with intraorbital extension is rare. Plain radiograph may be useful; however CT scan is the best modality of investigation for diagnosing and treatment planning. In asymptomatic osteomas, serial follow-up can be done. Surgery is performed in the presence of symptoms and signs. We report a case of 60 years old woman with a large osteoma of right ethmoid sinus extending into the ipsilateral orbital cavity.

Summary

Introduction

Osteomas are the common benign tumor of paranasal sinuses frequently arises in the paranasal sinuses[1,2,3,4]. We report rare case of a 60 years old female with a giant osteoma of right ethmoid sinus extending into the ipsilateral orbital cavity. Physical examination showed facial asymmetry with lateral displacement of the right eye Her visual acuity and visual field was normal. Figure 1c: Coronal reformatted CT image (soft tissue window) showing large dense lesion partially occupying the right nasal cavity and ethmoid sinus and extending into the right orbit by displacing the lamina papyracea, medial rectus muscle and globe towards left side. Within, partially occupying the right nasal cavity and right ethmoid sinus and obstructing the right osteomeatal complex with resultant right maxillary sinusitis.
