Abstract:
Objective To investigate the gastrointestinal imaging (GI)performance of herniation of pure abdominal omental fat (PAOF)into the esophagus hiatus(EH).Methods 7 cases of PAOF herniated into EH found by GI and MSCT were collected.The performance of GI was analyzed and compared with MSCT.Results 4 cases with large soft tissue shadow around lower segment esophagus,its density are lower,esophageal mucosa was showed coarse disorderly in the range of 2-4 cm of lower segment esophageal in the mucous membrane phase,of which 1 case with the mucosal line of esophagus at the j unction of esophagus and the superior border of the soft tissue slung up.Mild stenosis lumen of flexible wall was displayed in the filling phase,the upper bound of the lesions was often visible.3 cases with obtuse His angle,of which 1 case its change was shown with position.A more larger cystic fat density shadow was showed in MSCT right side of lower segment esophagus.3 cases were almost normal GI performance,among them 1 case of esophageal diaphragmatic ampulla lasting and a smaller cystic fat density shadow was showed in MSCT right side lower segment esophagus.The connection of the lower part of cystic fat density shadow to abdominal fat was showed all in 7 cases by MSCT MPR,and left gastric artery was shown to point to or protruded into EH by arcuate form.Conclusion A slight change of mucous membrane and lumen of lower segment esophagus which bounded above with larger and fade soft tissue density shadow and His angle obtuse variable were the special GI performance of the herniation of PAOF into EH,and the diagnose depended on MSCT.
