    Abstract

    Fludarabine phosphate is approved for the treatment of advanced B-cell chronic lymphocytic leukemia refractory to alkylating agents. We report two cases of disabling but reversible neurotoxicity in a patient with mycosis fungoides and a patient with chronic lymphocytic leukemia who received standard doses of fludarabine (20 to 25 mg/m2 per day for 5 days) every 28 days for 6 to 8 cycles. Serial brain magnetic resonance imaging scans in the patient with mycosis fungoides showed rapid evolution of white-matter changes with subsequent complete resolution.
