Intestinal lymphangiectasia caused severe diarrhea and generalized edema in a 40-year-old man. The diagnosis was established by clinical, laboratory, and duodenal biopsy findings. The abnormalities detected on computed tomography (CT) and scintigraphy using 99mTc human serum albumin are herein described and pertinent literature is briefly reviewed.
Magnetic resonance imaging is an effective means for evaluating the painful shoulder. It has been shown to display accurately pathology associated with impingement syndrome and is useful in the detection of tears of the glenoid labrum. The role of magnetic resonance imaging in evaluation of synovial pathology has not yet been defined. Additional work is needed in this area.

BACKGROUND/AIMS: The patterns of quantitative hepatobiliary scintigraphy for bilioenteric anastomoses have not been objectively defined. This study was undertaken to establish the patterns of quantitative hepatobiliary scintigraphy in the patients with bilioenteric anastomoses performed for repair of postcholecystectomy benign biliary strictures. METHODOLOGY: 37 patients with bilioenteric anastomosis (Study group) and 10 postcholecystectomy healthy subjects (Controls) underwent quantitative hepatobiliary scintigraphy. Study group patients were further categorized into: Group A (n=27) - normal clinical and biochemical parameters, and Group B (n=10) - abnormal clinical and/or biochemical parameters. On scintigraphy, time of maximal activity and time of clearance of half of the activity was calculated at the liver parenchyma and hepatic hilum. Time of appearance of activity in the intestine was also recorded. RESULTS: There was no significant difference in the scintigraphic parameters between Group A and Controls except for earlier appearance of activity in the intestines (p=0.036) in Group A. In Group B there was significant increase in the time of clearance of half of the activity at the liver parenchyma and hepatic hilum compared to Controls (p=0.003 and 0.036 respectively), and at the liver parenchyma compared to Group A (p=0.002). CONCLUSIONS: Quantitative hepatobiliary scintigraphic patterns in patients with bilioenteric anastomosis were similar to those of postcholecystectomy controls. Patients with abnormal biochemical parameters had significant delay in clearance of activity. Significance of these scintigraphic patterns in this subset of patients can be determined only on long-term follow-up.
