Omental infarction caused by laparoscopy-assisted gastrectomy for gastric cancer: CT findings
چکیده انگلیسی

AimTo investigate the computed tomography (CT) imaging features of omental infarction in patients who underwent laparoscopy-assisted gastrectomy (LAG) for gastric cancer.Materials and methodsA retrospective study was performed on 390 patients who underwent LAG for gastric cancer. Two radiologists evaluated the CT images for the presence of omental infarction. The CT pattern was characterized at initial presentation and the evolutional changes were evaluated. The initial CT appearance of omental infarctions were categorized into the following four types: type 1 (ill-defined, heterogeneous, fat density lesion); type 2 (well-defined fat density lesion with rim enhancement); type 3 (well-defined heterogeneous lesion with fat component); and type 4 (well-defined heterogeneous lesion without a fat component).ResultsOf the 390 patients involved, nine patients (2.3%; six male and three female with a mean age of 57 years) were diagnosed with omental infarction. Infarctions averaged 4.1 cm (range 2–7.3 cm) in diameter. Among nine patients with omental infarction, two patients had type 1 lesions, two had type 2, two had type 3, and three type 4. All infarctions became smaller and better defined with evolution. In two patients who presented with type 1 lesions on initial CT, each lesion was progressed to type 2 and type 3 on follow-up CT. In two patients with type 3 lesions on initial CT, the lesions changed to type 4 on follow-up CT.ConclusionAn awareness of the various CT features and evolutional changes in omental infarction after LAG for gastric cancer can help ensure the correct diagnosis and to avoid misdiagnosis for omental implants.
