1. Define fistulas and present their causes. 2. Identify-demonstrate CT and MRI findings in order to avoid missing the diagnosis.
Fistulas are abnormal connections between organs or vessels either directly or often via an abscess cavity.
They are usually named based on the participating anatomic structures. They can be idiopathic- or occur as a result of several causes either acquired,
which is the focus of our study or congenital.
Acquired causes include iatrogenic (post-surgical,
percutaneous procedures etc),
abdominal malignancies (colon cancer etc),
Findings and procedure details
Categorization of abdominal fistulas and cross sectional imaging findings Alimentary fistulas: Gut-gut fistulas (entero-enteric,
colo-gastric) : Oral contrast administration when performing CT may help depict the tract.
MRI images may also aid in diagnosing these connections.
The “star- sign” or “stellate pattern” is present in 26.3% ofenteroentericfistulas. Gut-skin/ gut-articular fistulas (entero-cutaneous,
perianal fistulas and...
MRI and CT imaging in combination with multiplanar visualization have a pivotal role in detecting fistulas,
as well as recognizing the etiology which is crucial for deciding the appropriate treatment.
