7B1-3 The recurrent neoplasm examined 12 years later. MRI shows a heterogeneously enhancing intraspinal mass centered at the level of L1 that obliterates the spinal canal, destroys the L1 vertebra, ranges up to 10.4 cm (AP) by 9.0 cm (transverse) and extends into the right posterior paraspinal soft tissues at the T12, L1, L2, and L3 levels. MRIs are shown consisting of T1 weighted pre-contrast (7B1), T1-weighted post contrast (7B2) and T2 (7B3). There are central areas of fluid signal intensity and decreased enhancement consistent with cystic change or central necrosis. Focal abnormal signal and enhancement are noted in the thecal sac, suggestive of drop metastasis. Operative procedure: T1 and L2 vertebrectomies for partial resection of mass.
