title: [A case of Crow-Fukase syndrome associated with chronic pachymeningitis].
abstract: A 34-year-old woman was admitted to our hospital in 1991, because of progressive headache, nausea and generalized edema. She was diagnosed as Crow-Fukase syndrome associated with plasma cell dyscrasia (IgA lambda type) in 1987, presenting with polyneuropathy, edema, and dermatologic changes. Those manifestations were improved with irradiation and corticosteroids, but headache, nausea and generalized edema gradually developed after the discontinuation of corticosteroid therapy in 1991. On admission, marked bilateral papilledema was noted but fever and meningeal irritation signs were absent. A spinal tap showed a clear cerebrospinal fluid (CSF) with an open pressure of more than 400 mmH2O, normal cell count, total protein level of 87 mg/dl, and IgG level of 12.3 mg/dl. The CSF culture for microorganisms was negative and the cytological study of CSF also was normal. De novo synthesis rate of CSF IgG was markedly elevated (35.3 mg/day). MRI of the head using Gd-DTPA revealed diffuse hypertrophic dura mater, which made the diagnosis of chronic pachymeningitis. Cerebral angiographies were normal. An RI cisternography demonstrated delayed absorption of the CSF without ventricular reflux. Gallium and bone scintigrams did not show any pathological accumulation of the isotopes in the head. The lack of abnormalities causing chronic pachymeningitis in this case suggests that the chronic pachymeningitis might be associated with Crow-Fukase syndrome. The development of increased intracranial pressure is not rare in Crow-Fukase syndrome but the etiology remained unknown in most cases. We therefore suggest that MRI study with contrast enhancement should be performed in cases of this condition with increased intracranial pressure.
