| Abstract: | Three patients (1 dog, 2 horses) ae described where myelography was complicated, purportedly by injection of contrast medium into the meninges superficial to the subarachnoid space. Contrast medium injected in this locationin a cadaver tended ot accoumulate dorsally within the vertebarel canal, deep to the dura mate but superficial to the subarachnoid space. The ventral marginof the pooled contrast medium had a wavy or undulating margin and the dorsal margin was smooth. Pooled contrast medium was believed to be sequestered within the structurally weak dural border cell layer between the dura mater and arachnoid membrane, or so-called subdural space. |
