Objective To evaluate CT features and diagnostic value of fungus infection of paranasal sinuses. Methods CT findings in 16 patients with fungus infection of paranasal sinuses proved surgically and pathologically were analyzed.Results CT findings of fungus infection of paranasal sinuses included: unilateral involved, maxillary sinus was mainly affected or other paranasal sinuses involved simaltaneously, the soft tissue within paranasal sinuses presented as hyperplasia of nodule and polyp-like, and there were some punctuated and tubercular calcification inside .Sinus cavity enlarged and the bone wall was destroyed in some cases. Conclusion CT manifestations of fungus infection of paranasal sinuses are of characteristics, CT scan is of important value in diagnosing this disease.

0.05)significant difference in 30 days (P0.001) between trunks groups and branches groups.Conclusion For the pationts with hypersplenism arteries were two or three branches,the PSE operation in the splenic arteriosus branches should be done,if splenic arteries were no truncus or truncus obvious crooked causing to introduce the catheter difficuty,the PSE operation in the splenic arteriosus truncus should be done.

OBJECTIVE: By studying the MRI apperances of postcricoid area invaded by laryngeal carcinoma, to identify the characteristic appearances of the invaded postcricoid area and to provide information on the early detection of the lesions. METHOD: Eighteen cases of MRI images of postcricoid area invaded by laryngeal carcinoma were included in this study. To find out the characteristic manifestation of the lesions, the destructions of surrounding structures and layers, and the invaded extent were observed. RESULT: In 18 cases the invaded lesions of postcricoid area include the mucous layer, submucous fat layer and the mucous layer of anterior wall. In 14 cases the invaded lesions of postcricoid area include the mucous layer, submucous fat layer and the mucous layer of the posterior wall. The soft tissue mass was found in 15 cases, and disappeared hypopharynx cavity in 16 cases. In 14 cases, the full-thickness of both anterior and posterior walls were invaded, accompanied with soft tissue mass and disappeared hypopharynx cavity. CONCLUSION The postcricoid area invaded by laryngeal carcinoma usually shows the destruction of normal structures, signal change in MRI and soft tissue mass. Being familiar with the imaging of the invaded postcricoid area is extremely important to early detect laryngeal carcinomas invading postcricoid area.
