Neuroradiol.1993 Jan 01; 14 AB - A case of nasopharyngeal amyloidoma with extensive skull base erosion is presented. CT revealed a large, relatively homogeneous, enhancing lesion; MR revealed a signal intensity iso- or slightly hyperintense compared to muscle on T1- and T2-weighted images, with a moderate degree of contrast enhancement. When an erosive mass is encountered at the skull base in a submucosal location in the nasopharynx, and MR demonstrates short T2 relaxation with signal iso- or slightly hyperintense relative to muscle, amyloidoma should be included in the differential diagnosis.
