Mucoceles of the Posterior Paranasal Sinuses and Visual Disturbance.

Mucoceles of the paranasal sinuses.

Mucoceles of the paranasal sinuses: MR imaging with CT correlation.

The MR findings in six cases of paranasal sinus mucoceles are described. Two basic MR appearances were encountered: either moderate to marked signal hypointensity in the expanded sinuses on T1- and T2-weighted images (four patients) or moderate to marked signal hyperintensity on T1- and T2-weighted images (two patients). These patterns appear to represent inspissated or hydrated sinus contents,...

Unilateral Frontal and Ethmoidal Mucoceles of the Paranasal Sinuses in a Seventy-Four-Year-Old Man

Introduction: Mucoceles of the paranasal sinuses are relatively rare. A very busy otolaryngology department does not have more than a few cases each year. Bilateral, multiple, and multiloculated cases are extremely unusual. Case Presentation: We report a 74-year-old man with two separate mucoceles in left ethmoid and frontal sinuses with pansinusitis. After marsupialization of mucoceles and fun...

Anatomic variations of posterior paranasal sinuses and optic nerve.

Aim To define direct anatomical relations of the sphenoidal (alae minores), ethmoidal sinuses and optic nerve, with an emphasis on determining the effect of age on pneumatisation and dehiscence. Methods This retrospective, descriptive study involved 60 consecutive patients: 30 patients younger than 30 and30 patients older than 60 years of age. All patients underwent computerized tomography(CT)....

Bilateral asymmetrical mucoceles of the paranasal sinuses with unilateral orbital complications.

We report the rare occurrence of bilateral asymmetrical mucoceles of the paranasal sinuses that resulted in a unilateral orbital complication. The patient was a 47-year-old woman who presented with complaints of diplopia, blurred vision, and protrusion of her right eye that had progressed over a period of several months following an upper respiratory tract infection. Computed tomography detecte...
