Abstract
Objective To analyze the imaging features of bone giant cell tumor in order to improve its diagnostic accuracy. Methods The X-ray, CT and MR I performances of 28 cases with bone giant cell tumors proved pathologically were analyzed retrospectively. Results The typical X-ray features were eccentric, expanded, soap-bubble liked destruction of bone in long bone of four limbs; the common features in CT scans were also eccentric, expanded bone destruction which had a thinned cortex, cortical breakthrough in different degrees, a irregular peripheral sclerosis and ridge; the MR1 imaging were secondary signal intensity on T,WI, secondary to high or mixed signal intensity on T2WI, normally with a band of low signal intensity around the tumor, occasionally wilh liquid-liquid level. Conclnsion There are definite characteristic features of giant cell tumor in X-ray manifestations. The internal structure of giant cell tumors can be detected by CT and MRI, and soft tissue lump producing into the pelvic and abdominal cavities can be seen in lumbosacral giant cell tumors. X-ray examinations, combined with CT and MR1 together can improve the diagnosis of the disease. Besides above, CT and MRI examinations
can also help to facilitate surgical planning.[Chinese Medical Equipment Journal,2012,33(4) :71-73,91]关键词
