Ivory vertebra, metastatic prostate carcinoma

The ivory vertebra describes a dense sclerotic vertebral body on plain film or CT, with the correlate on MR being very low signal intensity on both T1- and T2-weighted sequences. L2 and S2 are involved in this fashion in the presented case, with additional metastatic lesions noted posteriorly in L1 and L3, together with mild posterior expansion of the L2 vertebral body. As in this patient, the posterior portion of the vertebral body is on occasion infiltrated first in metastatic disease.
