Ileal Adenomyoma: Extremely Rare Cause of Intussusception

Abstract

Adenomyoma of the gastrointestinal tract is a benign tumor that is usually found in the stomach and is occasionally found in the duodenum and biliary tract; however, it is very rarely found in the small intestine. Adenomyomas of the small intestine that usually present with intussusception are very rare in children. In this study, a case of ileal adenomyoma presenting with intussusception was described.

Ultrasound diagnosis of the small intestinal adenomyoma in children

“…According to our knowledge, no US description of intestinal adenomyoma, except for one case report of our group, was published [28]. Some case reports that had a definite diagnosis of intussusception were examined by US, but no adenomyoma mass was detected [4,25,26,29]. In our study, two patients were misdiagnosed, possibly because the child had a small intestine atresia or Meckel's diverticulum, with extensive dilation and obvious air accumulation in the proximal intestine, which made the identification of the adenomyoma difficult.…”

“…Adenomyomas usually occur in the stomach, duodenum, and periampullary area, but rarely can occur also in the jejunum and ileum [2][3][4]. The occurrence of adenomyomas in the small intestine is exceptionally rare in children, with only 27 cases described in 23 case reports [1][2][3][4]7,8,[12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. Adenomyomas in the periampullary area usually present as biliary obstruction or abdominal pain, whereas jejunal and ileal adenomyomas usually cause intussusception and present as abdominal pain [12].…”
