[Pathologic dens fracture in irradiated malignant neurofibroma]
1Abteilung Strahlentherapie und spezielle Onkologie, Medizinischen Hochschule Hannover.
Abstract:
A pathological dens fracture in a 47 year old patient with malignant neurofibroma is described. These tumours are very rare but the prognosis is very poor because of rapid proliferation and early metastatic progression. In the described case, bone osteolysis remained unnoticed until manifestation of clinical symptoms. The pathological fracture occurred despite irradiation of the dens.
