Multiple clips within the pelvis in keeping with radical prostectomy.
There are bilateral near water attenuation collections tracking along the iliac vessels, surrounded by surgical clips, the right measuring 9.9 x 5.3 x 8.9 cm, and the left measuring 2.5 x 3.8 x 3.8 cm.
The right-sided collection demonstrates wall thickening and apparent rim enhancement. Contrast is seen within the urinary bladder on delayed phase imaging.
Findings are compatible with bilateral post-operative lymphoceles, the right much larger than the left. The wall thickening and rim enhancement would not be expected in a simple lymphocele, and is strongly suggestive of infection, which would explain the patient's fevers.
