Learning objectives: To synthesize the criteria that can differentiate a meningioma (typical or less typical) from different meningioma-like mass, illustrating by several clinical cases.
Background: INTRODUCTION Meningiomas represent approximately 15% of all symptomatic and about 33% of all incidental (asymptomatic) intracranial neoplasms. These are the most common nonglial primary tumors of the central nervous system and the most common extraaxial neoplasms, accounting for between 13 and 26 [...]
Findings and procedure details: TYPICAL MENINGIOMA has characteristic imaging findings: extraaxial, well defined focal mass, broad-based dural attachment, homogeneous densities (on CT) / intensities (on MR exam), close to those of grey matter, markedly, homogenous enhancement, both on CT and MR, enhacement of the adjacent thicken[...]
Conclusion: Understanding the similarities but also the distinct imaging features in an well-known anamnestic, clinical and etiopathogenic context, often allow a differential diagnosis between meningioma and "meningioma-like" process, avoiding unnecessary surgical acts.
