Findings are consistent with an infected lymphocele of the right paravesical and anterior pararenal space, causing mass-effect on the psoas muscle, kidney and right hemicolon. There is a simple lymphocele of the same region contralaterally.

Lymphoceles after prostatectomy occur as a complication of pelvic surgery, as a result of postoperative leakage from lymphatic channels. Lymphocele can present with lower urinary tract symptoms, lower abdominal pain and deep vein thrombosis. Therapeutic options for pelvic lymphocele often depend on factors such as the clinical status of the patient, size, position, infection risk, loculations and the recurrence of the collections. Symptomatic pelvic lymphoceles can be managed initially by percutaneous drainage or aspiration, with or without instillation of sclerosing agents.
