Title was changed:
Mobile Surgical Clip Granuloma (Clipoma)surgical clip granuloma - "clipoma"
Status changed from pending review to published (public).
Published At was set to .
Age changed from 65 year to 65 years.
Presentation was changed:
A 65 year old patient with historyHistory of chronic renal failure underwent routine CT scans to evaluate his renal transplant. PatientThe patient also had a remote history of small bowel surgery 35 years ago. An interesting incidental finding was noticed on sequential CT scans.
Body was changed:

Amputated appendices epiploicae account for the vast majority of free peritoneal bodies (also known as peritoneal loose bodies or peritoneal mice). Other differential diagnosisdiagnoses for peritoneal loose bodies include dropped gallstone, foreign body including surgical clip, fecalith, calcified dermoid, calcified echinococcal cyst, calcified uterine/gastric leiomyoma and spontaneous amputated ovary.  Although, dropped surgical clips have been known to be peritoneal loose bodies, the surgical clip granuloma presenting as a peritoneal loose body is quite rare.

Usually, the peritoneal loose bodies are innocuous and not clinically significant. There have been few case reports where peritoneal loose bodies were the etiology of urinary retention, bowel obstruction and chronic abdominal pain. The management of symptomatic loose bodies is usually surgical removal via laparoscopy.

Findings was changed:

On initial CT, a large oval 6 x 5 cm circumscribed smooth innocuous mass is present in left deep inguinal fossa (arrows). The mass had a surgical clip in the center. On subsequent CT obtained two years later, mass has moved to posterior deep pelvis (arrows). The bone window (third image) better depicts the surgical clip in the center (arrowhead).
