The treatment of bile collections is divided into: expectant attitude with radiological monitoring of the size and characteristics of the collection, percutaneous drainage guided by imaging tests (US/CT), endoscopic drainage depending on location and accessibility and surgical treatment. The clinical case of a man undergoing a scheduled hepatectomy was observerd, who presented a large asymptomatic subcapsular collection suggestive of bilioma, with progressive increase in size, spontaneously presenting a decrease until its resolution by fistulization to the hepatic angle of the colon confirmed by Radiological findings. The spontaneously formation of biliary fistulas to the colon is due to the extrinsic pressure of the collection on the intestinal wall with necrosis of the contact zone, being its presentation and radiological documentation exceptional.
