Case Reports
Facial nerve palsy as an early manifestation of relapse in T-cell acute lymphoblastic leukemia.
We describe a 14-year-old girl with T-cell acute lymphoblastic leukemia (ALL) who developed peripheral type facial palsy alternately on each side during remission. The cerebrospinal fluid examination and imaging studies of the brain including the temporal area failed to identify the etiology. ⋯ Review of the literature revealed that an isolated facial nerve palsy due to leukemic cell infiltration is a rare occurrence. Nonetheless one needs to keep in mind that it may represent the initial sign of a relapse in a patient with leukemia, particularly with T-cell ALL.
