“…Although it is almost always possible to diagnose cerebral meningioma by MRI [2,13,17,19] and to identify the histotype in about 80% of cases [6,15], experience of MRI in cystic meningiomas is still very limited [1,6,15] due to the relative rarity of this lesion [5,9,11,15,18].…”

MRI in the diagnosis of cystic meningiomas: Surgical implications

et al. 1997

Nine cases of cystic meningioma diagnosed by MRI are described. All cases were surgically confirmed. The lesion was extra-axial with a clear dural attachment. On T1-weighted images the solid component was iso-hypo-intense in 6 cases and iso-hyperintense in 3; on T2-weighted images it was hyperintense in 7 cases, iso-intense in 2. After i.v. injection of gadolinium, the solid component enhanced in all cases and a "dural tail" were visible in 8 cases. No gadolinium enhancement of the cyst wall was observed in Nauta's types II and III. The authors found MRI to be very useful for diagnosis of cystic meningioma but insufficient for differential diagnosis between types II and III according to Nauta. This aspect requires further study, especially in view of the implications of this differentiation in terms of surgical management.

“…Meningiomas are most often seen as homogeneous, markedly enhancing extra‐axial dural‐based mass lesions on postcontrast CT and T1‐WI MRI (Fig. 3a–f) (40, 41). Another characteristic of meningiomas is the dural tail sign; although not pathognomonic, it is most prevalent in meningiomas and seen in ≈60%–85% of the cases as a thickened, enhancing dural attachment (42).…”

Lesions masquerading as acute stroke

Rapid and accurate recognition of lesions masquerading as acute stroke is important. Any incorrect or delayed diagnosis of stroke mimics will not only increase the risk of being exposed to unnecessary and possibly dangerous interventional therapies, but will also delay proper treatment. In this article, written from a neuroradiologist's perspective, we classified these lesions masquerading as acute stroke into three groups: lesions that may have "normal imaging," lesions that are "symptom mimics" but on imaging clearly not a stroke, and lesions that are "symptom and imaging mimics" with imaging findings similar to stroke. We focused the review on neuroimaging findings of the latter two groups ending with a suggestion for a diagnostic approach in the form of an algorithm.

“…As a result, the decision to intervene will be increasingly influenced by radiographic findings. Radiographic criteria for the diagnosis of meningioma have improved 23 – 26 . Unfortunately, there are still no radiographic findings, or clinical criteria for that matter, that reliably distinguish lesions that will progress from those that will remain stable 27 .…”
