A 45 yr old female complains of progressive lower limb weakness, spasticity, urinary hesitancy. MRI shows intradural enhancing mass lesion. Most likely diagnosis is -: (A) Dermoid cyst, (B) Intradural lipoma, (C) Neuroepithelial cyst, (D) Meningioma
Answer is D. Ans. is 'd' i.e. Meningioma Among the given options, only meningioma shows enhancement on contrast scans."The radiologic image of a dural-based, extraaxial mass with dense, uniform contrast enhancement is essentially diagnostic, although a dural metastasis must also be considered. A meningioma may have a 'dural tail' a streak of dural enhancement flanking the main tumor mass, however the finding may also be present with other dural tumors." - Harrison
