[Uncommon tumors of the petrous bone. 4 cases (author's transl)]. 1981

R Charachon, and O Roux, and G Dumas, and B Pasquier

Four cases of uncommon tumours of the petrous bone treated by surgery alone or combined with radiotherapy are reported. There was one case embryonic sarcoma in a 3-year-old female child and one case each of chondroid chordoma, isolated plasmocytoma and malignant fibroid chondrosarcoma or histiocytoma with giant cells. The signal symptoms (pseudo-petrositis, isolated paralysis of a vocal cord, sudden deafness) may be misleading. The most helpful diagnostic methods are frontal tomography and CT scanning.
