Immature mesenteric teratoma causing intestinal obstruction

Hand-Assisted Laparoscopic Surgery for a Mesenteric Teratoma

“…24 Two of the 21 patients (9.5%) were diagnosed with immature teratomas. 14,22 This is a higher incidence of malignancy than that observed with mesenteric cysts (3%). Therefore, physicians should recognize the importance of possible malignancy when preoperative diagnostic imaging reveals fat-containing abdominal tumors.…”

“…Though computed tomography and magnetic resonance imaging examination are available, only 4 of the 21 patients (19%) with mesenteric teratomas were diagnosed before undergoing surgery. 14,19–21 The preoperative diagnoses in these patients include other common abdominal masses such as mesenteric teratomas misdiagnosed as ovarian cysts in 3 cases 7,22,26 and as a parasitic cyst in 1 case. 24 Two of the 21 patients (9.5%) were diagnosed with immature teratomas.…”

Benign cystic teratoma of the mesosigmoid: Report of a case

“…The occurrence of mesenteric teratoma in males is less common than in females [3,4]. These tumors more frequently occur in children than in adults, but rare cases of geriatric patients have also been reported [7][8][9][10][11][12][13][14][15][16][17][18]. Although cases with multiple masses have been described [14], mesenteric teratomas are usually solitary tumors with a diameter ranging 3-18 cm [12,14,17], located more often in the mesenterium than in the mesocolon [3].…”

“…Mesenteric teratomas may present with a variety of symptoms. These patients can be completely asymptomatic and just present with a nontender abdominal mass [8,16,17,19], while on the other hand they can also show signs of intestinal obstruction [10,12,14,15,20], and cause abdominal pain [7,14,15,18,[20][21][22][23].…”

“…Since the definitive diagnosis can be made only on the basis of histopathological examination, complete surgical removal of the cyst is the only way in the treatment of these patients. Although laparoscopic surgery has been used in some cases [3,19], the majority of authors, including our group, gave preference to a standard laparotomy approach [7][8][9][10][11][12][13][14][15][16][17][18][20][21][22][23]. We chose laparotomy over laparoscopy for several reasons: the size of the tumor, intestinal obstruction with consecutive bowel distension and a possible interference of the tumor with adjacent blood vessels and organs.…”
