Chronic lymphocytic leukemia (CLL) is the most common adult leukemia with an annual incidence of 2.7 cases per 100 000 persons.1 CLL or small lymphocytic lymphoma (SLL) affecting the CNS may present with headache, mental status change, cranial neuropathies, optic neuropathy, weakness, and cerebellar signs often owing to leptomeningeal infiltration.1,2 We report a unique case of a patient with CLL who presented with symptoms of diplopia owing to brainstem hemorrhage. To our knowledge, this is the first such case to be reported in the English language literature.
