Bioadhesive and histotoxic properties of ethyl-2-cyanoacrylate.

Ethyl-2-cyanoacrylate was applied to the cortex of rabbits to evaluate its bioadhesive and histotoxic behavior. The animals were killed at 4 or 10 days. Half of the animals were pretreated with dexamethasone. Our results indicate that the application of ethyl-2-cyanoacrylate to brain tissue produced severe superficial cortical necrosis but not bioadhesion. Pretreatment with steroids did not provide a significant protective effect.

Spinal intramedullary metastatic medulloblastoma. Case report.

Metastatic spread of medulloblastoma along the neuraxis by leptomeningeal seeding through the cerebrospinal fluid pathways is well known. The occurrence of extracranial metastases outside the neuraxis has been well established, but the occurrence of intramedullary spinal cord metastases not related to surface seeding is rare. A histologically documented case of the latter type is described.

Lumbar intradural arachnoid diverticulum with cauda equina compression.

An unusual case is reported of an intradural lumbar arachnoid diverticulum causing mild compression of the cauda equina and producing debilitating symptoms which were relieved by inadvertent drainage. A survey of the literature indicates that lumbar arachnoid diverticula are very rare. Only one other report of an intradural lesion of this type has been found. These lesions cause back pain or radicular pain and sensory disturbances when the patient is upright of bending forward. These symptoms are relieved by lying down. Percussion tenderness over the level of the diverticulum is a consistent finding. The key to the diagnosis is supine myelography.
