Right perirenal space computed tomography evidence of communication between the bare area of the liver

Computed tomography (CT) images from one cadaver and 11 patients with perirenal fluid collection were reviewed to study whether the right perirenal space communicates with the bare area of the liver. CT of a cadaver obtained after meticulous right perirenal injection of contrast media showed that contrast media extended superiorly into the bare area of the liver. CT of 11 patients with right perirenal hemorrhage or infection showed that fluid collection within the right perirenal space continued upward, crossing the coronary ligament, extending into the bare area of the liver. The inferior vena cava were completely or partially surrounded by fluid. CT of two patients with bleeding hepatocellular carcinoma showed that blood in the bare area continued extending downward into the perirenal space. We conclude that the right perirenal space is open toward the bare area of the liver and fluid collection within one space may communicate with the other space across the coronary ligament.

High-resolution CT findings of pleuropulmonary involvement in systemic lupus erythematosus

To evaluate the high-resolution computed tomography (HRCT) findings of pleurop버monaη involvement in systemic lupus erγthematosus (SLE) , we an혀yzed HRCT findings of 12 patients of clinically confirmed SLE with respiratory symptoms. In four patients, HRCT findings before and after chemotherapy were compared. The common HRCT findings were ground-glass opacity (100%), bronchial wall thickening (66%) , patchy parenchymal opacity (58%) , sept떠 or intralobular line thickening (58%) , micronodule (58%) , central core prominence (41 %), small pleural effusion (91 %), and pericardial effusion (33%). Follow-up HRCT obtained after treatment showed significant 띠lprovement of pleural effusion (4/4) , pericardial effusion (3/3) , pericardial thickening (1 / 1), patchy opacity (2/ 2) , and ground glass opacity (2/4). But bronchial wall thickening (2/ 2) and micronodule (2/2) were not improved Although there are no pathognomonic HRCT findings in SLE, bilateral small pleural effusion, ground glass opacity, subpleural patchy opacity, and micronodule are common and suggestive findings in the pleuropulmonaη involvement of SLE.
