ABSTRACT
PURPOSE:
The magnetic resonance(MR) appearance of 23 biopsy-proven meningiomas were retrospectively evaluated and correlated with histologic pattern ;fibroblastic, transitional, syncytial, angioblastic. MATERIALS ANDMETHODS:
Twenty three patients with biopsy-proven meningiomas were examined with MR imaging over a 3 years period. Images were assessed for average T1, T2 intensity score(1-5), degree of edema, calcification, cyst formation or necrosis, and dural tail sign.RESULTS:
Tl-weighted images showed only one significant correlation between fibroblastic type and angiobiastic type (p<0.04). Angioblastic type was more hypointense than gray matter(1.83/isointense to gray 3) on T1-weighted image. Syncytial and angioblastic tumors had average T2 intensity scores much higher than those of fibroblastic and transitional types. All three cases of angioblastic tumors had shown severe edema. Calcified lesions were much more common in transitional and fibroblastic types than in syncytial and angioblastic types.CONCLUSION:
MRI is a helpful diagnostic imaging modality with good correlation between its MR findings and histologic patterns.
