A 44-year-old woman was admitted to our hospital with a fever, dizziness, and gait disturbance after undergoing allogeneic hematopoietic stem cell transplantation for acute myeloid leukemia followed by graft-versus-host disease. She presented with cerebellar ataxia, nystagmus, and numbness of the lower extremities. Brain magnetic resonance imaging and perfusion scintigraphy showed progressive cerebellar involvement. ⋯ Anti-ganglioside antibodies were detected, but their levels did not follow the patient's clinical course. The patient did not respond sufficiently to steroids or other immunotherapies. We herein report the clinical characteristics of this case and a literature review.

A 42-year-old Japanese woman was admitted for the evaluation of proteinuria. She had a history of four habitual abortions and valvular heart disease, including severe mitral regurgitation and moderate tricuspid regurgitation. ⋯ Although the standard test for antiphospholipid (aPL) antibodies was negative, the patient was diagnosed with antiphospholipid syndrome (APS)-related disease by testing for phosphatidylserine dependent anti-prothrombin anticardiolipin antibody, a non-criterial aPL antibody. A kidney biopsy may lead to a diagnosis of APS in patients with negative laboratory test findings for APS.
