[Autoimmune neutropenia accompanied by Tolosa-Hunt syndrome].
A 47-year-old woman presented with severe neutropenia accompanied by diplopia and orbital pain. Her bone marrow was normal except for the absence of segmented neutrophils. Because the administration of granulocyte colony-stimulating factor (G-CSF) at a dose of 1 microgram/kg/day was not sufficiently effective and neutropenia developed, the patient was admitted to our hospital. Physical examination revealed painful ophthalmoplegia and hypoalgesia in the first region of trigeminal nerve, suggestive of Tolosa-Hunt syndrome. Severe neutropenia was observed in both peripheral blood and bone marrow, together with mild anemia and thrombocytopenia. The life span of red cells and platelets was shortened. High PAIgG levels, a positive Coombs test, and a positive test for anti-NA1 antibody suggested that blood cells were being destroyed by an autoimmune mechanism. Corticosteroid hormone therapy preceded by the administration of G-CSF at 5 micrograms/kg/day was effective for both neutropenia and in improving the patient's neurological findings.
