Late-onset optic pathway tumors in children with neurofibromatosis 1.

Author information

Department of Pediatrics, Feinberg School of Medicine, Northwestern University, Chicago, IL, USA.


Identification of new optic pathway tumors (OPTs) and progression of pre-existing OPTs in children with neurofibromatosis 1 (NF1) have been reported infrequently after age 6. The authors present eight children with NF1 (mean age 12.2 years) seen in three NF1 centers who had either late-onset (four of eight) or late-progressive (seven of eight) OPT. Continued monitoring of individuals with NF1 into adulthood for the development of OPTs and for progression of known OPTs is warranted.
