Optic nerve infiltration as an initial form of relapse of acute lymphoblastic leukemia
Keywords:
acute lymphoblastic leukemia, relapse, optic nerve infiltration.Abstract
Introduction: Optic nerve infiltration as an initial form of relapse of acute lymphoblastic leukemia is rare, although it is highly indicative of central nervous system involvement.
Objective: To update the knowledge about optic nerve infiltration as an initial form of relapse of acute lymphoblastic leukemia.
Methods: A review of the most relevant publications related to the subject during the last years was carried out. The search and localization of information was supported by the choice of keywords/descriptors that configured the search profile. The MeSH Database of PubMed was used. An extensive review was performed in Google Scholar and other systematic review mega search engines using TripDatabase and Cochrane.
Conclusions: Direct tumor cell infiltration and disease-specific hematologic alterations are the fundamental mechanisms of pathophysiology. Optic disc edema is the most distinctive ophthalmoscopic sign. Negative cranial magnetic resonance imaging, cytologic analysis of cerebrospinal fluid and bone marrow biopsy should not exclude the diagnosis. Combination therapy including localized radiation is a good treatment option. A considerable number of eyes recover visual acuity and show resolution of the infiltrative picture.
