Abstract
|
|
|
Inflammatory pseudotumors are benign tumors rarely that occurs in the head and neck. We present the case of a 39-year-old man presenting extraocular muscle palsy with inflammatory pseudotumor affecting the temporal bone including mastoid, middle
ear and
petrosal apex. At computed tomography and magnetic resonance imaging (MRI) scan, the lesion appeared as an enhancing mass of soft tissue occupying the majority of the mastoid bone and petrosal apex causing diplopia. The patient was treated with
conservative surgical excision (a open cavity mastoidectomy and tympanoplasty) and postoperative steroid therapy. Microscopic examination showed predominantly mature plasma cells. The patient remains free of disease 8 months after treatment. We
believe
this is the first case report of inflammatory pseudotumor affecting the middle ear and mastoid involving the petrous apex.
