“Dural sealant-oma” after posterior fossa surgery: illustrative case

This case adds to the growing body of literature on DuraSeal, highlighting the imaging and histological characteristics of "dural sealant-omas" and their expansile nature that can lead to the formation of a mass mimicking an abscess or a hematoma. In areas susceptible to compression, clinicians ought to be vigilant to identify findings consistent with the appearance of these dural sealant-omas. https://thejns.org/doi/10.3171/CASE25574.

Abstract

This case adds to the growing body of literature on DuraSeal, highlighting the imaging and histological characteristics of "dural sealant-omas" and their expansile nature that can lead to the formation of a mass mimicking an abscess or a hematoma. In areas susceptible to compression, clinicians ought to be vigilant to identify findings consistent with the appearance of these dural sealant-omas. https://thejns.org/doi/10.3171/CASE25574.
