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.

Serial magnetic resonance T2-weighted spin echo scans of brain in Patient 1.(top left)(top right)(bottom left)(bottom right)

A subtle abnormality in white matter is seen in the high temporoparietal area on the left on the initial scan , becoming much more extensive with right-sided involvement as well 6 weeks later , beginning to improve 2 weeks later , and resolving completely 6 weeks later , 3 months after the original scan. At no point was there cortical involvement.
