OBJECTIVETo explore the relationship of motor dysfunction of the lower extremities with the imaging appearances and clinical features of metastatic epidural spinal cord compression (MESCCs).
METHODSFrom July 2006 to December 2007, 26 successive patients with metastases of the thoracic, lumbar and the cervical spine were treated in our department. Forty-three main involved vertebra in all 26 patients were evaluated by magnetic resonance imaging and computed tomography, and were scored according motor dysfunction in this study. Fourteen patients (25 vertebrae) had motor dysfunction.
RESULTSAmong 26 patients, 12 cases with visceral metastasis,in which had motor dysfunction in 10 cases; 14 cases without visceral metastasis, in which had motor dysfunction in 4 cases; comparison between two groups, P=0.0079. Among vertebral presence of continuity of 43 main involved vertebrae, 16 vertebrae had motor dysfunction;among vertebral absence of continuity, motor dysfunction occurred in 9 vertebrae, comparison between two groups, P=0.1034. Among vertebral presence of lamina involvement of 43 main involved vertebrae, 11 vertebrae had motor dysfunction; among vertebral absence of lamina involvement, motor dysfunction occurred in 14 vertebrae, comparison between two groups, P=0.020 5. Among vertebral presence of protruding of vertebral posterior wall of 43 main involved vertebrae, 12 vertebrae had motor dysfunction; among vertebral absence of protruding of vertebral posterior wall, 13 vertebrae had motor dysfunction, comparison between two groups, P=0.0334. Among vertebral presence of involvement epidural space of 43 main involved vertebrae, 11 vertebrae had motor dysfunction; among vertebral absence of involvement epidural space, 14 vertebrae had motor dysfunction, comparison between two groups, P=0.003 6. Such factors as age, gender, whether or not received regular chem before admission, back pain degree of metastasis, received regular chem before admission, therapeutic efficacy of primary tumor, number of bony metastases outside spine, number of the main involved vertebrae, level of vertebral metastases location, level of continuous involved vertebrae, vertebral-body involvement, fracture of anterior column, fracture of posterior wall, and pedicle involvement had no effects on incidence of motor dysfunction due to MESCC (P>0.05).
CONCLUSIONMESCC with visceral metastases, lamina involvement, presence of outstanding buttocks sign of posterior wall,involvement epidural space tended to cause symptomatic MESCC. Incidence of continuity of main involved vertebrae occurred more frequently in the CUTS compared with other levels of spine.

Percutaneous sacroplasty is a safe and effective procedure for sacral insufficient fractures under CT or fluoroscopic guidance; although, few reports exist about sacral metastatic tumors. We designed a pilot study to treat intractable pain caused by a sacral metastatic tumor with sacroplasty. A 62-year-old man and a 38-year-old woman with medically intractable pain due to metastatic tumors of S1 from lymphoma and lung cancer, respectively, underwent percutaneous sacroplasty. Over the course of the follow-up period, the two patients experienced substantial and immediate pain relief that persisted over a 3-month and beyond. The woman had deposition of PMMA (polymethyl methacrylate) in the needle track, but did not experience significant symptoms. No other peri-procedural complications were observed for either patient.

Transcatheter arterial chemoembolization (TACE) has been used widely to treat patients with unresectable hepatocellular carcinoma. However, this method can induce various adverse events caused by necrosis of the tumor itself or damage to nontumor tissues. In particular, neurologic side effects such as cerebral infarction and paraplegia, although rare, may cause severe sequelae and permanent disability. Detailed information regarding the treatment process and prognosis associated with this procedure is not yet available. We experienced a case of paraplegia that occurred after conducting TACE through the intercostal artery to treat hepatocellular carcinoma that had metastasized to the rib. In this case, TACE was attempted to relieve severe bone pain, which had persisted even after palliative radiotherapy. A sudden impairment of sensory and motor functions after TACE developed in the trunk below the level of the sternum and in both lower extremities. The patient subsequently received steroid pulse therapy along with supportive care and continuous rehabilitation. At the time of discharge the patient had recovered sufficiently to enable him to walk by himself, although some paresthesia and spasticity remained.
