Endoscopic extraction of a peritoneal loose body: a case report of an infant

Abstract

A 2-month-old female infant with a peritoneal loose body presenting as an abdominal mass and urinary tract infection is described. Peritoneal loose bodies are usually found in the pelvis of adult patients. A peritoneal loose body should be considered in the differential diagnosis of a mobile lesion found in the abdomen.

Numerous peritoneal loose bodies with ileus

“…Shao-Chieh Lin 1 Kung-Chao Chang Nan-Haw Chow 1 We report a similar study in our institution, using Dako DuoCISH on tissue microarrays (TMAs) of breast cancer cases. One hundred and forty-seven consecutive cases of breast carcinoma were retrospectively selected from the files of the Departments of Pathology, Royal College of Surgeons in Ireland and Beaumont Hospital, Dublin, Ireland.…”

“…Sir: Peritoneal loose bodies, also known as 'peritoneal mice', are mobile lesions lying free in the peritoneal cavity. 1,2 They are usually small, white to pale grey, pea-shaped objects with a smooth glistening surface, found incidentally during laparotomy or routine autopsy without causing symptoms. 3 'Giant' peritoneal loose bodies, larger than 5 cm in diameter, presenting with various symptoms have been rarely reported.…”

“…To the best of our knowledge, this case, with up to 30 large peritoneal loose bodies, has more of these bodies than any other case in the literature. 1,3,4 A 55-year-old male presented with a 5-day history of epigastric pain, vomiting, nausea, and abdominal fullness. Physical examination revealed abdominal tenderness and hypoactive bowel sounds.…”

Peritoneal Mouse as Detected on 18F-FDG PET-CT

“…There are a few surgical case reports describing this uncommon entity (Nomura et al, 2003; Asabe et al, 2005; Mohri et al, 2007; Kavanagh et al, 2010). Two radiology case reports have described this finding on CT (Ohgitani et al, 2004; Gayer and Petrovitch, 2011).…”

Laparoscopic Retrieval of a Peritoneal Mouse

“…The appendix epiploica detaches from the colon and becomes a peritoneal loose body or “peritoneal mouse”. It is not uncommon to find small loose bodies during laparotomy [4]. Normally, they have little or no pathological significance, and their prevalence is not clearly documented.…”
