TY - JOUR T1 - Amyloidoma of the nasopharynx: CT and MR findings. JF - American Journal of Neuroradiology JO - Am. J. Neuroradiol. SP - 215 LP - 218 VL - 14 IS - 1 AU - J L Hegarty AU - V M Rao Y1 - 1993/01/01 UR - http://www.ajnr.org/content/14/1/215.abstract N2 - 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.
