History of coccygeal chordoma status post resection Again seen are surgical changes relating to prior coccygeal resection which are unchanged from the prior exam. There is increased signal abnormality on fluid sensitive sequences, which does not enhance on postcontrast images most consistent with postoperative changes. Note is made of foci of metallic susceptibility artifact in the surrounding area which are postoperative in etiology. No pathologic enhancement is identified on postcontrast sequences. No evidence of residual or recurrent tumor.The patient is status post hysterectomy. There is a focus of increased signal abnormality on both T1 and T2-weighted images within the S2 vertebral body, which demonstrates fat signal intensity on all sequences, likely representing a hemangioma, appearing similar to the prior study. Similar marrow signal changes are noted at the S3 and S4 which are also unchanged. Although this examination was not protocoled for evaluation of the lumbar spine, again seen is disc protrusion at the level of L5/S1, which results in narrowing of the lateral recess and posterior displacement of the S1 nerve root as well as left neural foramen narrowing. Overall these findings are unchanged from the prior exam. There is also an apparent disc protrusion at the level of L4/L5 but these findings are better evaluated on the corresponding MRI of the lumbar spine.
Postoperative changes without evidence of residual or recurrent tumor.
