Metastatic meningioma: The role of whole‑body diffusion-weighted imaging.

We report the case of a 74-year-old male patient with a completely resected anaplastic meningioma who developed multiple metastases two years later (subcutaneous tissue near the surgical area, cervical lymph nodes, lung, pleura and bones). The primary tumor and all of the metastases showed a significant restricted diffusion. Whole‑body diffusion-weighted imaging (DWI) was performed for assessment of the metastases. This case demonstrated the usefulness of this technique in screening extracranial metastases in patients with malignant meningiomas.
