RT Journal Article SR Electronic T1 Bone erosion caused by sinonasal cavernous hemangioma: CT findings in two patients. JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 1176 OP 1178 VO 16 IS 5 A1 H J Kim A1 J H Kim A1 J H Kim A1 E G Hwang YR 1995 UL http://www.ajnr.org/content/16/5/1176.abstract AB We report two cases of cavernous hemangioma originating in the sinonasal cavity. Although CT showed some enhancing areas within both tumors, the substantial bone destruction caused by these tumors made it difficult to differentiate them from the more common malignant epithelial tumors. Angiography was performed in one patient and showed characteristic pooling of contrast material.
