Abstract:
Objective To study CT findings, diagnosis and differential diagnosis for prostate cancer. Methods 28 cases with prostate cancer confirmed by surgery and pathology, of them 4 cases were recurrence after operation. Results In 24 cases confirmed by surgery 21 (87.5%) were diagnosed by CT. Their CT appearances were : (1) Focus: in non enhanced scanning the prostate was enlarged unevenly in 18 cases. The density of the mass was slightly lower than the normal prostate in 17 cases, and equal to normal in 11 cases. Patchy calcification was seen in 2 cases moderate. In enhanced scanning, 22 cases showed nodular enhancement but slightly less than normal, 6 cases were equal to normal. (2) Metastastic lesions: 8 cases had local thickened bladder wall, 4 cases had enlarged seminal vesicle with unneven density, 2 cases with thickened anterior wall of rectum.And pelvis mass, enlarged lymph nodes, bony destruction of pelvis and pulmonary metastasses 1 case for each respectively. Conclusion (1) It is emphasized enhanced CT study should be a routine examination in the diagnosis of prostate cancer by CT; (2)CT can define the extent of the lesion and metastases thereby helpful to predict the prognosis and evaluate the effect of treatment.
