[An elderly case with sarcoidosis whose symptom of dementia was effectively treated by steroid].
We report a case of a 74-year-old woman whose symptoms of dementia may have been caused by sarcoidosis and in whom steroid treatment was effective. The patient, who had recieved treatment for hypertension, started to exhibit symptoms of dementia one year previously and progressively deteriorated during the month before she was admitted. Brain computed tomography showed multiple lacunae infarctions. Chest X-ray showed mild swelling of bilateral lymph nodes in the mediastinum. The patient was referred to an ophthalmologist because of complaints of disturbed visual field, and bilateral uveitis was diagnosed. Negative tuberculin, high serum ACE value and high absorbance in the lung hila on Ga scintigram were recognized. Lymph node biopsy revealed typical granuloma compatible with sarcoidosis. Cerebrospinal fluid (CSF) showed elevated protein concentration without an increased cell count. EEG showed a diffuse slow wave pattern. We observed the progression of dementia shown by declining scores of Mini-Mental State Examination (MMSE) from 17/30 on admission to 7/30 on day 30 after admission. Although enhanced MRI of the brain showed no typical findings of sarcoidosis, we started treatment with prednisolone (50 mg/day) based on the suspicion that the progression of dementia was caused by sarcoidosis. One month after the start of steroid treatment, we observed gradual improvement of symptoms. The MMSE score increased to 20/30. According to previous reports, elderly sarcoidosis patients relatively rare by show dementia, but sarcoidosis should be considered in the differential diagnosis because steroid treatment can be effective.
