An 8-year-old boy sought medical advice due to perforating injury by a bamboo piece in the left orbit. Computed tomography (CT) on day 2 of injury showed low absorption in the presumed intraorbital foreign body. CT on day 9 showed high absorption values in the area. These CT scans failed to show the foreign body itself. Magnetic resonance imaging (MRI) on day 11 showed a high intensity signal area simulating inflammatory granulation on T1 weighted spin echo images, containing 4 rectangular low signal areas. Surgical removal of foreign bodies showed that the high intensity area corresponded to granuloma lesion and that the 4 rectangular low signal ones were bamboo fragments. CT was useful in locating the sites of foreign bodies and MRI was additionally helpful in showing the surrounding granulomatous tissue.
