Oculomotor nerve invasion of acute myelogenous leukemia demonstrated by magnetic resonance imaging.
A 53-year-old male was diagnosed as having acute myelogenous leukemia (M2, FAB). He complained of double vision and right blepharoptosis after receiving remission induction chemotherapy. Magnetic resonance imaging (MRI) showed enlargement of the bilateral oculomotor nerves. Intrathecal injections of methotrexate and cytosine arabinoside were partially effective and repeated MRI showed shrinkage of the enlarged oculomotor nerves, after therapy. This case shows the importance of MRI in the early diagnosis of CNS leukemia.
