A Case of Intraperitoneal Loose Body Which Showed the Appearance of Liver Tumor

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

“…Peritoneal loose bodies are usually found in the pelvis of middle-aged and elderly individuals [3,5,7,[9][10][11][12][13][14]. To our knowledge, there has been no published report of a peritoneal loose body being found in an infant.…”

“…Although giant loose bodies are extremely rare [7,[11][12][13], some cases have demonstrated large palpable abdominal masses and the appearance of alimentary and/or urinary symptoms [12].…”

“…In the case of chronic torsion of appendix epiploica, the blood supply is shut off; thereafter, saponification and calcification of the fat contents occur, and the pedicle atrophies. Finally, the appendix epiploica detaches from the colon and becomes a peritoneal loose body [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Other origins of loose bodies, especially calcified free bodies, are myoma uteri, lymphatic glands in the mesentery, echinococcal cysts, urinary stones, foreign bodies, and ovarian tumors [1,3,5,6,13].…”

“…These free bodies are occasionally discovered at operation and during routine autopsy [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. The most common origin of the loose bodies is appendix epiploica [1][2][3][4][5][6][7][8][9][10][11][12][13][14], and some authors have also suggested that large loose bodies can be formed by an accumulation of peritoneal serum to the appendix epiploica [13]. In the case of chronic torsion of appendix epiploica, the blood supply is shut off; thereafter, saponification and calcification of the fat contents occur, and the pedicle atrophies.…”
