case_images: The opacification of the left frontal sinus appeared to be due to dense material without contrast enhancement which extended into the orbit through anterolateral (20 x 30 mm) and inferior (13 mm) breach of the sinus (Figure 1). Through Lynch-Howarth procedure, the frontal sinus was opened and the content was removed (Figure 2).

case_images: A histology slide of the cholesterol granuloma of the frontal sinus reported here. The fibrous connective tissue contains the characteristic "needles" of cholesterol surrounded by multinucleated foreign body giant cells (hematoxylin-eosin, original magnification x50).
