Become familiar with the diverticula of the gastrointestinal tract. Understand the modality of choice and the imaging features for each diverticulum. Avoid diagnostic pitfalls and recognize the common complications of diverticular disease.
Diverticula are congenital or acquired outpouchings of the gastrointestinal (GI) tract,
normally occurring at points of weakness in the wall of the alimentary canal secondary to traction (pulling) or pulsion (increased intraluminal pressure) forces.
Congenital diverticula are true diverticulum,
involving all three layer of the bowel wall: the mucosa,
the smooth muscle,
and the serosa.
Acquired diverticula are characteristically false diverticulum which do not involve all three layer and are...
Findings and procedure details
HYPOPHARYNGEAL/ESOPHAGEAL DIVERTICULUM Fluoroscopic esophagram is the gold standard for diagnosis of diverticulum of the upper GI tract.
These diverticula are often incidentally discovered on fluoroscopic swallow studies performed for other indications.
A pitfall of this technique occurs when small diverticula are obscuredby superposition on the main column of barium in the esophagus.
This can be overcome by rotating the patient.Using continuous video fluoroscopy in anteroposterior (AP) and...
Radiologists should be familiar with the spectrum of GI tract diverticular disease.
An understanding of the image modalities available is key for initial diagnosis of the disease,
especially in the setting of acute symptoms or complications.
While diverticula are often asymptomatic,
medical management or surgical correction may be necessary in the setting of chronic symptoms or acute complications.
