Term of the day: "Mini Brain Sign"
Many tumors involving the axial skeleton can be expansile, have low signal intensity on T1-weighted images and high signal intensity on T2-weighted images, and involve the entire vertebral body. These imaging characteristics are nonspecific. Minibrain appearance has been found characteristic of Plasmacytoma. The characteristic appearance of thickened cortical struts is probably a result of a stress phenomenon from the lytic process of the plasmacytoma forcing the remainder of the bone to increase thickness as a compensatory response to weakening bone.
Requesting readers for any characteristic images you may have for sharing.
