CLINICAL CASE The case is presented of a 21 year-old male with a history of left proptosis and diplopia of two weeks of onset. The MRI showed an ethmoid-orbital vascular lesion with anterior skull base invasion and orbital extension. Biopsy of the ethmoid confirmed fibrovascular tissue, which supported the diagnosis of angiofibroma. DISCUSSION It is a benign neoplasm with local characteristic...

Fibrous dysplasia is a benign fibro-osseous lesion progressing with one or more bone involvements in the skeleton. Even though it is a benign tumor, it may potentially transform into a malignant one. While the most frequently involved zones in the head-neck zone include the maxilla, mandible, parietal, occipital, and temporal zones, the involvement of the ethmoid bone is rather rare. This artic...

Over a period of 2 years we reviewed the CT scans of 217 patients with recurrent sinusitis. Our findings revealed a number of cases of osteomeatal complex disease with no frontal sinus involvement. This result is difficult to reconcile with the concept of a common drainage in the middle meatus shared by the frontal and anterior ethmoid sinuses. We conclude that the frontal sinus drains separate...

A 61-year-old man presented with acute, painful loss of vision in the left eye due to a central retinal artery occlusion. Fluorescein angiography confirmed the central retinal artery occlusion and also identified a nasal posterior ciliary artery occlusion. CT scanning revealed a left medial orbital mass with adjacent ethmoid sinusitis. Transnasal ethmoid biopsy disclosed mucormycosis. A left ex...

Ossifying fibroma (OF) is a benign fibro-osseous lesion which was first described by Menzel in 1872. It is commonly seen in the head and neck regions and represents an aggressive pattern when the midface and paranasal sinuses are involved. We report a 36 years old white woman with OF in the right ethmoid sinus. Computed Tomography (CT) scan images showed a hyperdense mass. Transnasal endoscopic...

RATIONALE Mucocele is a disease lined primarily by epithelium, and occurs mainly when the sinus ostium is obstructed. PATIENT CONCERNS We report a case of a 37-year-old man who presented with painless proptosis of the right eye and diplopia. DIAGNOSES The preoperative finding was mucocele of the ethmoid sinus. INTERVENTIONS We performed endoscopic sinus surgery, which included uncapping o...
