Anterior Ethmoid Mucocele Simulating Frontal Mucocele

An ethmoid mucocele causing diplopia

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...

Bilateral frontal sinus mucocele.

A male patient aged 37 years with a history of cranioencephalic trauma 21 years ago, reports a left frontal tumor beginning 4 months ago. Magnetic resonance imaging revealed a lesion suggesting mucocele (Figure 1). The patient underwent endoscopic bilateral frontal ethmoid sinusectomy. The option was made for external left frontal ethmoidectomy due to intense bone sclerosis in the frontal reces...

Sudden Hemianopsia Secondary to Ethmoid Sinus Mucocele

Paranasal sinus mucoceles are benign cystic lesions, filled with mucus, occurring due to an obstruction of involved sinus ostium. They are indolent, locally expansive, and destructive. Surgical treatment must be performed and, when done at the correct time, may prevent sequelae. We present a case of ethmoid sinus mucocele with orbit involvement and permanent optical nerve injury.

Management of frontal mucocele with frontal fracture

[Atypical frontal sinus mucocele. A case report].

CLINICAL CASE We report a case of a 46-year-old woman who developed a tender, painful mass in the left superior eyelid over a period of about 6 months. This was a frontal mucocele with atypical clinical and histopathologic features. DISCUSSION Most mucoceles arise from the frontal or ethmoidal sinuses. Frontal mucoceles usually cause outward and downward displacement of the globe, and are oft...
