Аннотация
BACKGROUND CONTEXT: Bovine serum albumin and glutaraldehyde (BSAG) (BioGlue) is a surgical adhesive widely used for off-label applications in neurosurgical procedures to minimize the risk of cerebrospinal fluid leakage after dural closure.
PURPOSE: To describe magnetic resonance imaging (MRI) and computed tomography (CT) aspects of two cases of postoperative BSAG expansion causing delayed cauda equina compression requiring further surgery.
STUDY DESIGN: A case report.
PATIENT SAMPLE: Two cases of delayed cauda equina compression complicating the closure, with BSAG, of small unintentional tears in the dura requiring lumbar decompressive surgery.
OUTCOME MEASURES: They included postoperative CT and MRI findings.
METHODS: We compared postoperative imaging and perioperative findings during subsequent surgery.
RESULTS: In both cases, imaging showed cauda equina compression due to epidural masses found during subsequent surgery comprising BioGlue. These masses appeared slightly hyperdense on CT scans and markedly hypointense on T2-weighted MRI scans.
CONCLUSIONS: When applied as a thick layer during use as a dural sealant, BSAG may swell, leading to a symptomatic "glue-oma" giving a hypointense image on T2-weighted MRI scans.
