The etiology is not fully understood but the condition can appear in variable locations, sizes and morphology in the body. We describe a large HO in a scar, discovered 25 years after a laparotomy of the upper abdomen. The calcification led to mechanical complaints and resection gave resolution of symptoms. HOs can be incidental findings on plain radiographs. CT-scan can show typical mature peripheral mineralization with central lucency. If symptomatic, resection must be performed after maturation. Maturation can be examined with activity-oriented imaging as 3-phase bone scan or SPECT-CT. UR - https://qims.amegroups.org/article/view/11183
