A CASE OF LEIOMYOMA OF THE JEJUNUM WITH ABCESS FORMATION

Abstract

Leiomyomas of the small intestine are relatively rare. This paper reports a case of leiomyoma of the jejunum presented with abcess formation. A 37-year-old man was admitted to the hospital because of fever and a mass in the lower abdomen.
Ultrasonography and computed tomography demonstrated a mass measuring approximately 8cm in diameter in which air and fluid were found. Magnetic resonnance imaging demonstrated that the intensity of the wall of the mass was as similar as that of the musculature. Leakage of th contrast medium from the lumen of the upper jejunum into the cavity of the mass was found by a radiography of the small intestine. Superior mesenteric arteriography revealed a hypervascular mass.
Laparotomy revealed a jejunal tumor growing extramurally, adherent to the mesentery of the sigmoid colon. Partial resection of the affected jejunum and sigmoid colon was performed. Histologically, it was leiomyoma of the jejunum with abcess formation.
Among 184 case reports of leiomyoma of the jejunum or ileum between 1989 and 1997 in the Japanese literature, there are only two cases other than this case which presented with abcess formation.
