It was caused by the penetrafion of the wooden foreign body under unknown circumstances. Case report. Repeated CT scans did not reveal the presence of the foreign body before MR imaging and ultrasonography. The removal (43 × 8 mm) was done one month after the injury by osteoplastic orbitotomy, using microsurgical technique. Three months later the signs of inflammation and eye protrusion withdrew. Motility of the left upper lid and eye were normal. Conclusion. MR imaging and ultrasonography were decisive in the diagnose of organic foreign body in the orbit.
