Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1] Associate Editor(s)-in-Chief: Haytham Allaham, M.D. [2]

Overview

Overview

MRI may be helpful in the diagnosis of Langerhans cell histiocytosis. Findings on T1 weighted MRI imaging suggestive of Langerhans cell histiocytosis include a well-defined, isointense, brain lesion associated with reactive dural enhancement.[1][2]

  • MRI may be helpful in the diagnosis of Langerhans cell histiocytosis.[1][2]
  • MRI image characteristics observed among medulloblastoma patients include:
  • T1 weighted image demonstrates:
  • An isointense lesion associated with reactive dural enhancement
  • T2 weighted image demonstrates:
  • Heterogeneously hyperintense lesion
  • T1 weighted image iwth gadolinium contrast demonstrates:
  • Marked contrast enhancement
