Nineteen months after diagnosis, the patient again complained of myodesopsia and developed bilateral optic neuritis. Cerebrospinal fluid analysis revealed an increase in blasts, although peripheral blood and bone marrow examination confirmed that the patient remained in a molecular response to tyrosine kinase inhibitor (TKI) therapy. The patient was diagnosed with an isolated central nervous system blast crisis, a rare occurrence with second-generation TKI therapy, and the initial presentation of myodesopsia represented a symptom of this condition.
