Meningioma or Mimic: Look Twice and Save a Life
Description & Learning Objectives
Meningiomas are the most common brain tumors in adults and are often incidentally detected on imaging studies. Most often diagnostic confidence is high on the basis of imaging findings. Meningiomas may demonstrate atypical features such as cysts, hemorrhage, or metaplastic changes that can be misleading. Several other neoplastic and granulomatous inflammatory conditions may mimic meningiomas. Differentiating these lesions from meningiomas is important because treatment strategies and prognoses differ. We will review and discuss the typical and atypical imaging features of meningiomas and how to differentiate meningioma from its mimics.
Upon completion of this activity, participants will gain strategies to describe the typical and less common imaging findings of meningiomas, diagnose meningiomas presenting in uncommon locations, and differentiate meningiomas from mimics.
