Objective To evaluate the diagnostic value of CT manifestations of the lung in localized Wegener′s granulomatosis(LWG). Methods CT findings of the lung in 11 patients with LWG verified by pathology were retrospectively analyzed. Results All the cases presented with multiple nodules of soft dense varying from 0.5 cm to 3.0 cm in diameter which distributed in the lung. Cavities were commonly seen in the larger nodules. Seven cases showed the wedge-shaped lesions with their bases situated externally on the pleural surface and with their convex apices directed at the hilum. The massive shadow with blurred margins was found in 4 cases. The nodules and wedge-shaped lesions demonstrated peripheral enhancement. Some of them presented with “vascular sign”. Conclusion The CT features of LWG were multiple nodules and cavities within nodules coexisting with wedge-shaped lesions, peripheral enhancement of nodules, and “vascular sign”. The law of change and the features of enhancement were relatively characteristic to the diagnosis of LWG.

This report described the cell ultrastructure in six cases of non-granulocytic leukaemia (two cases each for acute lymphocytic, and acute monocytic leukaemia, and two for multiple myeloma) .According to their ultrastructural characteristics, the differential diagnosis of the three leukaemic cell types and the nature of their dense granules and cytoplasmic fibrils under the electron microscopy have been discussed.

Objective To investigate the causes of intractable abdominalgia after simple choleystectomy and analyse the therapeutic effect of endoscopic sphincterotomy (EST).Methods 84 patients undergoing EST were retrospectively viewed from 1987 to 1998. Results Sixty five out of 84 patients were followed up, in which the clinical signs disappeared completely in 51 cases (78%), and there were 6 cases with relapsing symptom(9%),3 cases with intermittent relapsing symptom (4%). Therapy was ineffective in 5 cases. The intractable abdominalgia is a specific sign of postcholecystectomy syndrome. EST is effective in removing the nervous structure in duodenal papilla submucosa and sphincter muscle layer responsible for abdominal pain, therefore eliminated or relived the pain.Conclusion EST has a significant effect on intractable abdominalgia after simple cholecystectomy in the majority of patients.
