Abstract

A cow was presented with an avulsed horn in the right orbit following fight with another cow. The plain radiography could not confirm the depth or shape of the lodged foreign body as the presence of bony orbit impaired the visualisation of the shape of less radiopaque horn shell. Contrast radiography was performed using 5 ml diluted iohexol. This helped in ascertaining the depth of the foreign body and shape of the end of the foreign body and the possible damage to the underlying tissues. The bony orbit was intact. The horn was removed under auriculopalpebral and retrobulbar nerve block. But there was irreparable damage to the eye, progressive shrinkage of extraocular muscles leading to enophthalmos and downward deviation of the eye ball. This is the first reported case of contrast radiography of an avulsed horn in the orbit of a cow.
