Endoscopic retrograde cholangiography has now evolved into a highly sophisticated diagnostic and therapeutic tool in patients with hepatobiliary-pancreatic disorders. However, this procedure is associated with risks of significant complications such as cholangitis, pancreatitis, hemorrhage, and perforation which have been widely recognized. Hepatic subcapsular biloma is a very rare and less recognized complication of this procedure.
