Meningioma differential diagnosis
The differential for dural lesions is extensive and includes 1):

Solitary fibrous tumor/hemangiopericytoma (SFT/HPC) and meningioma exhibit similar radiographic features, however, they differ in their prognoses. Preoperative differentiation between them is important for determining the treatment and follow-up plan.
Plasma cell granulomas
In the setting of hyperostosis consider:
Sclerotic metastases (e.g. prostate and breast carcinoma)
Specific location differentials include:
