..Intracranial chondrosarcoma showing hyperostosis of the skull has not been reported in the cases. The discussion includes its differential diagnosis, origin, and clinical behavior...

..The imaging features of cervical spine injury are often modified by associated spondylosis deformans, DISH and other systemic disorders. The value of MR imaging in such cases is emphasized...

..These patients have no cerebellar neurological deficit. This rare abnormality is probably a maldevelopment of the hemispheric part of the posterior lobe of the developing cerebellum, and no clinical significance can be elicited...

..The purpose of this study was to evaluate the use of multislice CT in the evaluation of vascular patency in patients during hepatic arterial infusion chemotherapy of liver tumors...

..In conclusion, MSCTA is accurate in assessing arterial anatomy and abnormalities. MSCTA can provide adequate information for planning of radiological catheter placement for HAIC...

..A chondroblastoma of the posterior component of the seventh cervical vertebra with tetraparesis was reported. Imaging studies showed an expansile destructive lesion with mineralization...

..SN volume loss is not found in Parkinson disease, and this finding is compatible with that of recent pathology reports in the literature...

..The lesion recurred 7 months later with no systemic treatment in the interim, when the diagnosis of lymphoma was finally made. Spontaneous regression may be related to potentiation of the host immune response, which affects tumor growth...

..Such pathways include the greater sciatic foramen, the obturator foramen, the femoral canal, the muscular lacuna, the pelvic outlet, and the inguinal canal...
