[Pure red cell aplasia with thymoma, myasthenia gravis and normal pressure hydrocephalus].
Cases of pure red cell aplasia with thymoma and myasthenia gravis are rare. We described a patient who had concomitant pure red cell aplasia, thymoma, myasthenia gravis and a normal pressure hydrocephalus. A 63-year-old man with disturbances of gait, left blepharoptosis and anemia was presented to our hospital. Laboratory examination on admission revealed severe anemia. Bone marrow aspirates showed erythroid hypoplasia of marked degree. Chest x-ray and chest CT revealed a tumor to the right of cardiac wall. The tensilon chloride test and antiacetylcholine receptor antibody were positive. A hydrocephalus was demonstrated with brain CT. Cerebrospinal fluid pressure was in the normal range. He was diagnosed as having pure red cell aplasia with thymoma, myasthenia gravis and a normal pressure hydrocephalus. This appears to be a fairly rare case. It seems important to consider that a normal pressure hydrocephalus may have immunological disorders.
