Bilateral Facial Palsy a rare presenting symptom of acute lymphoblastic leukemia with CNS and BM Relapses

Here, we report a case of pre-B cell who presented with bilateral lower motor neuron facial nerve paralysis because of meningeal spread of CNS relapse in a patient who had bone marrow (BM) and CNS relapse while on maintenance therapy. [...]of presentation, extra-medullary spread of disease was not present, computerized tomography (CT) scan of the head was normal and cerebrospinal fluid (CSF) analysis did not show CNS involvement of the disease. [...]the simultaneous bilateral facial palsy is very rare presenting symptom, some underlying severe disease and rarely idiopathic.
