This is a novel technique for evaluation of fistulas. It is based on acquisition of thin sections with MDCT (16 or more slice MDCT), with simultaneous instillation of water-soluble, iodinated contrasts into the active external or internal opening.

Educational Goals / Teaching Points
Describe the anatomic locations, causes and clinical features of uncommon fistulas. List appropriate diagnostic imaging studies. MDCT fistulography. How to do it. Identify the radiologic finding in the various types of fistulas.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
A TCMD fistulography procedure used to view a fistula, an abnormal passage between two or more anatomic spaces or organs or a pathway that leads from an internal cavity or organ to the surface of the body. A sinogram is a similar procedure done to assess a sinus, an abnormal passage or cavity that originates or ends in one opening, often on the skin. Contrast material is used to help identify the start of the fistula/sinus, its pathway and what organs are involved. Is important to identify the anatomic locations and clinical features to proceed. Fistulas are diverse in their anatomy and clinical presentation. Radiologists must be familiar with the radiologic findings for both accurate diagnosis and, in many cases, guidance of management planning.

We intend to show you, from a transparent and rigorous viewpoint, the most interesting cases in our work. Some patients have fistulas: Echinococcal disease with bronchobiliary fistula. Post tubercular gastropulmonary fistula. Primary aortoesophageal fistula and other most common causes (Enterocutaneous Fistula, pelvic fistulas, etcetera).
