Case Report Long-standing Hiccup in a Patient with Sarcoidosis Tetsuri KONDO, Toshimori TANIGAKI, Hideo SUZUKI, Seiji TAMAYA, Yasuyo Ohta and Hajime YAMABAYASHI The patient was a 67-year-old male. A diagnosis of sarcoidosis was made both by transbronchial lung biopsy and by scalene node biopsy. The findings of his chest roentgenogram were categorized as the group II. There were no symptoms during follow-up period of one year at the out-patient clinic with no medication. The chest X-ray findings of the patient wereslowly progressive. Intractable hiccup developed one year after his first visit to the hospital. With administration of prednisolone, serum angiotensin converting enzyme level decreased promptly, and the incidence of the hiccup attack decreased. As the dose of prednisolone was tapered, the hiccup recurred. All the drugs used for hiccup including quinidine sulfate and methochropramide was not effective. A thoracic CT revealed slight enlargement of mediastinal lymph nodes. A brain CT and a brain MRI demonstrated no abnormalities. Acetazolamide, which induces acidosis in brain extra-cellular fluid, worsened the symptoms. As prednisolone was given again, infiltrates on the chest roentgenogram began to resolve and the incidence of hiccup decreased. We conclude that the long-standing hiccup observed in this patient may be brought by the lesion in central nervous system due to sarcoidosis.
