“…To our knowledge, only 30 cases of cholesterol granuloma in the paranasal sinuses have been reported in the literature. In the majority of previous reports, cholesterol granuloma was found in either the maxillary [1Á10] or frontal sinus [10Á13]; there is only one report of cholesterol granuloma of the ethmoid sinus [14]. We report a rare case of cholesterol granuloma arising in the posterior ethmoid sinus mimicking meningocele.…”

Cholesterol granuloma is usually associated with chronic middle ear disease, less common in the orbit, and rare in the paranasal sinus. Cholesterol granuloma is thought to be initiated by hemorrhage, impaired drainage, and interruption of aeration. Here we report a case of cholesterol granuloma arising in the posterior ethmoid sinus mimicking meningocele. Magnetic resonance imaging is useful for differential diagnosis, and endoscopic surgery is effective for the management of cholesterol granuloma arising in the ethomoid sinus.

“…Incomplete resorption results in a foreign body reaction to blood and its byproducts. [2][3][4] Cholesterol granuloma of the frontal bone is a rare entity, typically involving the lateral part of the supraorbital ridge in middle-aged men. The most common presenting symptom is proptosis and downward displacement of the globe.…”

“…On MR images, cholesterol granuloma is characterized by high signal intensity in both T1-and T2-weighted images. [2][3][4][5] The differential diagnosis of cholesterol granuloma includes other homogeneous lesions that occur in the diploic space of the frontal bone. This includes dermoid cyst, epidermoid cyst, and aneurismal bone cyst.…”

Cholesterol granuloma is a chronic inflammatory process with associated foreign body reaction to hemorrhage-related cholesterol crystals. In the head and neck region, cholesterol granulomas most frequently occur in the middle ear and mastoid, but they only rarely have been reported in the paranasal sinuses and the frontal bone. Those lesions involving the frontal bone typically occur in the lateral aspect of the supraorbital ridge and more commonly affect men. 1,2 We present a case of a middle-aged woman with a cholesterol granuloma of the medial frontal bone in close proximity to her frontal sinus. The diagnosis and management of this lesion are discussed.
