title: [Pachymeningoencephalitis: case report].
abstract: A 59-year-old man presented with generalized convulsion. MR imaging demonstrated a homogeneously enhanced dural lesion infiltrating the parenchyma in the right parietal region. He had no history of sinusitis and the lesion a resembled malignant tumors, so surgical treatment was performed. The histopathological studies showed pachymeningitis extending to the cerebral parenchyma, so the diagnosis of pachymeningoencephalitis was made. After the operation, the patient had no neurological deficits and anticonvulsant therapy was continued. We report the third case of idiopathic local pachymenigoencephalitis that we could range extensively in the world. The clinical features and pathogenesis are discussed.
