Objecfive To investigate multi-slice spiral CT(MSCT)appearances of pulmonary infections after liver transplantation(LT)and the diagnostic values of MSCT.Methods The clinical data and CT images of liver transplantation receptors were reviewed from 200 1 August to 2007 June,the types,onset time and CT appearances of pulmonary infections were analyzed retrospectively.Chi square test was used for the statistics.Results The incidence rate of pulmonary infections after LT was 32.9/(174/529),the mortality was 9.8/(1 7/174),The incidence of bacterial infection,fungus or associated fungus infection,and virus or associated virus infection were 17.2/(n=91),14.7/(n=78)and 2.3/(n=12)respectively,the pulmonary infections were seen in 64.7/,28.7/and 6.6/of patients 1 to 30 days,31-90 days and after 90 days following LT.Consolidations(n=32),ground-glass opacities(n=22),nodules(n=10),reticular or lineal opacities(n=4)were found in 45 patients who had CT examination,there were no statistic differences in incidence rate between bacterial infection and mycotic infection(P＞0.05).Conclusion Pulmonary bacterial and fungus infection are common after LT.and often present as the mixed infection,the high risk period for infection is within 30 days after LT,thoracic CT stall is very important for characterizing the pulmonary infections after LT.

Objective To improve identification with regard and accuracy of diagnosis to CT appearances of pulmonary infections after liver transplantation(LT) .Methods CT findings of pulmonary infections after LT were retrospectively analyzed.Results The main CT manifestations included consolidation in 32(the lesions mostly in the right or both lower lung zones),ground-glass attenuation in 22,(the lesions distribution were often bilateral and diffuse),nodules in 10(multiple and bilateraly,the diameter of lesions was all less than 3 cm), and seven less than 1 cm,including diffuse and miliary nodules of lungs in 3,graticule or line shadows in 4,the lesions were in bilateral upper lobes in 2 and distribution extensively in bilateral lungs in 2.The most common CT findings of lung bacterial infection after LT were consolidation ,and ground-glass attenuation,while for pulmonary mycotic infection consolidation,ground-glass attenuation and nodule were all often seen.Conclusion CT is valuable to the diagnosis of pulmonary infections after LT.

OBJECTIVE: Analyzing the clinical manifestation, diagnosis and management of isolated sphenoiditis in children, retrospectively, was to get more information of the disease and to supply correct treatment early. METHOD: The symptoms, signs and imaging data of seventeen cases with isolated sphenoiditis hospitalized in our department from June 2001 to January 2010 were analyzed retrospectively. RESULT: Nine out of seventeen patients had the chief complaint of headache, three patients had blood in nasal discharge and had a fever, and five patients had postnasal drip with headache and a slight fever. The disease lasted for three months to one year. Five patients showed nasal discharge in rhinologic examination, one patient had solitary polyps in sphenoethmoid recess, eight patients had adenoid hypertrophy and the last three patients showed no positive signs. CT scan or MRI revealed opacification in sphenoid sinus. Eight patients received normative antibiotic therapy and were cured. The rest nine patients received endoscopic sinus surgery. The complaints relieved after the surgery and there was no signs of recurrence in 1 to 5 years of follow-up. CONCLUSION Headache can be the chief and unique symptom of isolated sphenoiditis in children, which was easy to misdiagnose and miss diagnosis. CT or MRI was the evidence of diagnosis. Antibiotic therapy could be used for acute sphenoiditis. Patients with chronic sphenoiditis should receive endoscopic sinus surgery as early as better. From supraturbinal to sphenoid sinus natural ostia is the best way in sphenoidotomy.
