Background:
While calcification of orbital hemangiomas has been reported previously, no reports exist of heterotopic ossifications occurring within the orbit.
Case Description:
A 30-year-old male presented with spontaneous onset of painless progressive proptosis of the left eye, with diplopia. The preoperative radiologic findings are presented. The lesion was excised completely. The pathologic features and probable causes are discussed.
Conclusions:
Heterotopic ossification of the orbit should be considered in the differential diagnosis of an orbital lesion showing radiologic features of calcification or ossification.
