title: Multiple myeloma: short T2 on MR imaging.
abstract: We describe a rare case of multiple myeloma with marked hypointense areas on both T1- and T2-weighted images. Amyloid deposition and calcification were not found histologically. Hypointensity on T2-weighted images may be caused by distributed free radicals produced by significant macrophages.
