The Angelchik antireflux prosthesis, used for hiatal hernias, can appear as a mass on CT scans if dislodged. This imaging artifact highlights the importance of recognizing the prosthesis

Area of Science:

Gastroenterology and Surgical Imaging
Medical Device Technology

Background:

The Angelchik antireflux prosthesis is a silicone, doughnut-shaped device used to treat gastroesophageal reflux disease secondary to hiatal hernia.
Accurate placement is crucial for efficacy and to avoid complications.

Observation:

Dislodged Angelchik prostheses can present a diagnostic challenge on computed tomography (CT) due to their soft tissue density.
The prosthesis may be misinterpreted as a neoplastic or inflammatory mass lesion.

Findings:

CT imaging of a normally placed Angelchik prosthesis is demonstrated.
A case report details the successful diagnosis of prosthesis dislodgment using CT.

Implications:

Radiologists must be aware of the potential for Angelchik prostheses to mimic mass lesions on CT scans.
