Intraabdominal knoglenydannelse – heterotop mesenteriel ossifikation

Calcified bowel mesentery – heterotopic mesenteric ossification
A 64-year-old man suffered blunt abdominal trauma. He developed ischaemic colon and had a colectomy with primary anastomosis, complicated with anastomotic leakage. A temporary stoma was created. Six months later when the stoma was to be reversed, the bowel mesentery was found to be extensively calcified. Heterotopic mesenteric ossification is an extremely rare condition. The pathogenesis is unknown but associated with mesenteric ischaemia, generalised peritonitis or abdominal trauma. Treatment should be as conservative as possible, avoiding surgery to prevent further ossification.
