The adductor longus abscess was aspirated and grew polymicrobial bowel flora. A pubic symphysis arthrogram was therefore performed to assess for an enteric fistula.
An 18G needle was inserted into the pubic symphysis under ultrasound and fluoroscopic guidance and water-soluble contrast injected. Contrast filled a loop of ileum posterior to the pubic symphysis via a narrow tract extending superiorly from the joint. Contrast also filled the right adductor collection.
A fistula between the pubic symphysis and ileum was confirmed.
