Gastrohepatic ligament: normal and pathologic CT anatomy.


In a review of 200 consecutive CT scans of the upper abdomen, the structures within the gastrohepatic ligament (GHL) were well seen in 182 (91%). In 85% of these 182 patients, the largest structure visible within the GHL was 6 mm or smaller. A total of 27 patients had a structure larger than 6 mm within the GHL; this finding could be explained in 13 by the presence of a normal anatomic variant. Of the 14 others, 12 had known tumor arising in or known to have spread to the upper abdomen. Two patients had no obvious explanation. Fourteen patients with cancers of the stomach (9 patients), pancreas (3 patients), and esophagus (2 patients) had 57 intact nodes that were evaluated pathologically. Of these 40/40 benign nodes and 10/17 malignant nodes were less than or equal to 8 mm in size. When anatomic variants are excluded, the finding of rounded structures greater than 8 mm in the GHL is a reliable indicator of left gastric node involvement by carcinoma or lymphoma or of coronary venous dilatation.
