OBJECTIVE: Spontaneous intracranial hypotension(SIH) is a rare condition presented with cardinal postural headache and low CSF pressure. The authors describe the characteristic clinical features, imaging findings, and treatment methods in the patients with spontaneous intracranial hypotension. METHODS: Between May 1994 and Aug. 2001, eight patients were diagnosed with spontaneous intracranial hypotension based on characteristic radiologic and clinical findings in our department. All cases were shown diffuse meningeal enhancement(DME) on magnetic resonance(MR) image. Two cases had subdural hematoma. RESULTS: The most characteristic feature on Brain MR image is DME with/without subdural fluid collection. Radionuclide image reveals direct leaking point and rapid appearance of urinary bladder activity. Direct leaking points were detected in all four cases who performed radioisotope study. Autologous epidural blood patches were applied to four cases, and all of them were improved without complication. Among four patients treated with conservative method, three were improved, but one patient was died of spontaneous chronic subdural hematoma. CONCLUSION: We suggest that 1) meticulous studies need to be performed aggressively if SIH is diagnosed clinically and radiologically, 2) the most effective study may be radioisotope study, and 3) if leaking point is found, aggressive management such as autologous epidural blood patches is recommended.

In 1897, Poncet described polyarthritis in patients suffering from tuberculosis which was not caused by tuberculosis infection of the joints. Poncet's disease is characterized by a polyarthritis that occurs during the acute tuberculosis infection in which no mycobacterial involvement can be found or other known cause of polyarthritis detected. It is a different entity from tuberculous arthritis, which is usually monoarticular and is caused by direct tuberculous infection. It was little known for pathogenesis of Poncet's disease, but immunologic reaction was suggested. Poncet's disease is associated with an excellent prognosis with rapid resolution on commencing therapy and no sequelae. Therefore, recognition of Poncet's disease can be important. Poncet's disease remains a diagnosis of exclusion.Recently, we experienced one case of Poncet's disease which have characterized by the clinical manifestations, and report this case with a review of the literatures.
