title: [The value of MRT in primary extramedullary plasmacytoma involvement of the head-neck area].
abstract: Six patients with a primary extramedullary plasmocytoma in the head and neck were examined using MR imaging. The morphological appearance of these lesions was described to support the radiologist in the differential diagnosis of this rare lesion. All tumours appeared as oval-shaped and sharply delineated without any signs of infiltration. After contrast media application a distinct central inhomogeneity could be proved in all cases. Furthermore, demoscopical, clinical and therapeutical problems were discussed based on the literature.
