title: A rare case of 'blow-up' fracture of the orbit in a child.
abstract: We present a case of blow-out fracture of the superomedial orbital wall in a 6-year-old boy. The initial plain radiograph showed an intact orbital margin and opacification of the ethmoid sinus. A fine-cut CT scan of the facial bones revealed a complex fracture of the medial orbital wall extending into the orbital roof, with migration of fracture fragments into the anterior cranial fossa. Suspicion for unusual orbital fractures is crucial when assessing a child for orbital trauma, especially when plain radiographs do not display the typical signs.
