Abstract
Localised amyloidosis in the head and neck is a rare disease. This report presents a 43-year-old woman with localised amyloidosis of the hard palate. Multislice helical computed tomography and magnetic resonance imaging findings are discussed. Computed tomography findings are non-specific with various degrees of contrast enhancement resulting from the degree of vascularity in the lesion. Signal intensities on both T1- and T2-weighted magnetic resonance images resemble those of skeletal muscle, and significant enhancement on enhanced T1-weighted magnetic resonance imaging is noted.
