Pneumoappendix after an inversion appendectomy: an unreported radiologic finding.

Radiographically detectable gas only occasionally fills the lumen of the vermiform appendix (pneumoappendix), and the diagnostic significance of this gas remains unresolved in the radiologic literature. The following case report is a previously unreported finding of a postoperative plain abdominal radiograph showing a dilated pneumoappendix after an inversion-ligation appendectomy. A brief review of the surgical technique is included to help explain these radiographic findings.
