title: [Two cases of cranial pachymeningitis presenting only severe continuous headache or convulsion].
abstract: In cranial pachymeningitis, headache, cranial nerve palsies, and ataxia were the most common clinical manifestations. We reported two rare cases presenting only headache or convulsion as a main symptom. A 66-year-old man was suffering from severe continuous headache for years with no other clinical symptoms. Laboratory data revealed positive RA test and elevated RAPA. With oral steroid therapy, his headache was subsided. A 39-year-old woman visited us with convulsive attacks as only symptom. Biopsy of the thickened dura revealed granulated epithelioid cells without central necrosis. With antituberculosis therapy, hypertrophy of dura, as well as the symptom, was disappeared. It is difficult to diagnose pachymeningitis when patients manifest only headache or convulsion. We suggest to carry out Gd-enhanced MR scan in these cases.
