Patients with end‐stage renal disease require to establish vascular access for regular hemodialysis. The creation of arteriovenous fistula (AVF) is usually a safe procedure; however, there could be complications such as bleeding, hematoma, pseudoaneurysm, thrombosis, infection, and steal syndrome. A rare complication of such vascular manipulation could be formation of lymphocele. We present a case of a 67‐year‐old man who presented with a progressively enlarging mass 12 days after the surgery for AVF creation at the site of surgery in the right upper arm. Ultrasonographic examination revealed a fluid‐filled cystic structure measuring about 4.2 × 3.6 × 1.9 cm under the skin just above the anastomosis. The fluid was aspirated using ultrasound‐guided fluoroscopy that relieved the swelling. The analysis of aspirate suggested the cyst to be a lymphocele. The mass re‐enlarged to its previous size in the next 3 days. While under observation for signs of complication, regular intermittent compression and a low‐fat diet completely resolved the lymphocele over the subsequent 3 months. The less common occurrence of such lymphocele post AVF creation needs to be evaluated for its potential for complication, in the absence of which the lymphocele is amenable to conservative management using regular intermittent compression and low‐fat oral diet.
