- W2884341039 abstract "Focal areas of T2 hyperintensity are seen on magnetic resonance imaging (MRI) in patients with neurofibromatosis type 1 (NF1). These lesions are commonly known as unidentified bright objects of the brain. We have seen similar lesions in the spinal cord of the same patient population. Our aim was to determine the prevalence and characterize the imaging features of these T2 hyperintense spinal cord lesions in children with NF1.A search of our hospital's medical imaging database yielded all children with NF1 and MRI of the brain and/or spine between February 2014 and April 2017. Medical imaging was reviewed for T2 hyperintense signal changes and medical records were reviewed of those children with T2 hyperintense spinal cord lesions.During the study period 155 children underwent a brain MRI and 72 had a spine MRI. One hundred twenty-three (79%) showed multiple cerebral T2 hyperintense lesions and six (8%) had non-contrast enhancing spinal cord T2 hyperintensities with five children having had a follow-up scan. The one child without follow-up imaging was not further pursued. Interval scanning showed stable appearance of the spinal cord lesions in four children and signal reduction in one child. All five children with T2 hyperintense changes in the spinal cord had an MRI brain and all (100%) also exhibited cerebral T2 hyperintensities.Focal areas of signal hyperintensity in the spinal cord are the corollary of the better described cerebral T2 hyperintensities in individuals with NF1." @default.
