NIMG-19. GLIOMA-LIKE INTRAPARENCHYMATOUS LESIONS ON MRI BRAIN IN ADULT NEUROFIBROMATOSIS TYPE 1 PATIENTS

摘要

INTRODUCTIONNeurofibromatosis Type 1 (NF1) is a neurocutaneous disorder with a highly increased risk of gliomas. In addition, unspecified T2 hyper intensities (Unidentified Bright Objects; UBOs) are often seen on the MRI brain which may disappear over time. The distinction between large UBOs and glioma is sometimes difficult. In addition, enhancing intraparenchymatous lesions have been described that disappear over time. As the incidence and evolution of these lesions have been insufficiently studied in NF1 adults, we conducted a retrospective study on this topic.
