Hypertrophic intracranial pachymeningitis associated with chronic otitis media: A case report

ABSTRACT

A 59-year-old woman was admitted to our hospital because of occipital headache and multiple cranial nerve dysfunction. The patient had been suffered from chronic otitis media. MRI of the brain showed a thickened and markedly enhanced dura mater in the temporal lobe. The patient underwent a left temporal craniectomy and dural biopsy. Histopathological examination revealed thickened duar amter infiltrated with giant cell, lymphocytic and plasma cell infiltration. The fungus, acid-fast and PAS stains were all negative. After administraion of steroid, cranial nerve disturbances and headache improved. The cause of the hypertrophpic intracranial pachymeningitis in this patient was thought to be related with the chronic otitis media, although the clinical course of the patient was similar to the idiopathic hypertrophic pachymeningitis.
