69-year-old female with drainage from groin wound and associated induration. Evaluate for bilateral groin seromas versus abscess. ABDOMEN:LUNG BASES: Bibasilar atelectasis. No acute infiltrates or effusions. Mild cardiomegaly.LIVER, BILIARY TRACT: Cholelithiasis. The multiple ill-defined hepatic hypodensities. The small at the hepatic dome on image 14 of series 3. The largest is adjacent to the hepatic hilum in the medial segment of the left lobe measuring 2 cm in greatest dimension at axial image 37 of series 3. A second lesion in the medial segment of the left hepatic lobe measures 1.6 cm in greatest dimension on axial image 36 of series 3. These hepatic lesions could be better characterized with a multiphase dedicated liver CT or MRI examination.SPLEEN: No significant abnormality noted. Splenule at the hilum. PANCREAS: No significant abnormality notedADRENAL GLANDS: No significant abnormality notedKIDNEYS, URETERS: There are multiple bilateral renal cortical cysts. There is a nonobstructing punctate left upper pole renal calculus. No hydronephrosis.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality notedOTHER: Aortobifemoral bypass graft is in expected position and appears widely patent. Diffuse atherosclerotic changes with vascular calcifications.PELVIS:UTERUS, ADNEXA: No significant abnormality notedBLADDER: No significant abnormality notedLYMPH NODES: Multiple bilateral borderline enlarged inguinal lymph nodes, probably reactive.BOWEL, MESENTERY: No significant abnormality notedBONES, SOFT TISSUES: No significant abnormality notedOTHER: Bilateral groin fluid collections, largest on the left. Both fluid collections appear uniloculated with mildly thickened enhancing wall. No gas bubbles. Both of these collections lie superficial to the distal aortobifemoral bypass graft anastomotic sites. Small amount of free fluid in the pelvis. The smaller right-sided fluid collection and has a maximum diameter of approximately 2.5 cm. The left sided collection extends craniocaudally for 13 cm and has a transverse dimension of 5.5 cm.
Bilateral uniloculated groin fluid collections at the distal anastomoses of aortobifemoral bypass graft. Enhancing rims suggest these are more likely abscess than seroma.. Multiple hepatic hypodensities are better characterized with dedicated liver CT or MR examination, if indicated.
