PDFAbstract
Objective To summarize the multislice spiral CT and MRI findings of chordoma. Methods 34 patients with chordoma who were admitted in our hospital between January 2010 and March 2016 were selected as the study object. Spiral CT and MRI examination were performed and the multi-slice spiral CT and MRI findings were summarized. Results The predilection sites of patients with chordoma were skull base and sacrococcygeal region, irregular lobulated, elliptical or nodular. CT examination showed inhomogeneous low density shadow or low and equal density shadow, with clear boundary, osteolytic and expansive bone destruction, partially visible punctate or patchy calcification in chordoma. After enhanced scan, there were inhomogeneous and moderate enhancement. MRI plain scan showed that the tumors were smooth outline, clear edge, homogeneous or mixed low or equal signal on T1WI, obviously high signal or equal signal on T2WI,and equal or high signal on DWI. Ehanced scan showed particlelike light and moderate enhancement. Conclusion CT is good for the display of bone destruction and tumor calcification in chordoma. MRI has resolution to high soft tissues, which can display lesions with cystic degeneration, hemorrhage, calcification and other pathological changes. Each of them has its advantages and disadvantages. Both of them are of relatively higher value in the clinical diagnosis of chordoma.
