Plasmacytoma Simulating Meningioma on Brain Scan

摘要

The flow study and static images of the brain scans of two patients with plasmacytoma of the skull were identical to the pattern most commonly seen with meningioma. There was a prominent blush on dynamic imaging which did not wash out combined with an intense uptake on static views adjacent to a meningeal surface. In patients with known multiple myeloma, the diagnosis of plasmacytoma of the skull or cranial cavity should be considered when this characteristic pattern is seen.
