Primary intraosseous meningioma diagnosis

X-ray, head computed tomography, and Cranial magnetic resonance imaging are used as methods of radiological screening in diagnosing intradiploic meningioma. Radiological screenings have also found a mixed type showing both osteoblastic and osteoclastic activities ¹⁾.

Head computed tomography can be used to best define the margins of meningiomas in the bone window and MR imaging can be used to identify adherent tissue involvement. Scintigraphy and PET-CT can be used for the differential diagnosis. Bone scintigraphy shows an increased metabolic activity of the bone region in question when positive

The tumor is the cause of this increased metabolic activity, which can also be seen in arthrosis, infections and traumatic conditions.
