    Rapid neurological recovery with spontaneous resolution of acute subdural hematoma after severe head trauma: A case report of auto-decompression phenomena
    (Elsevier, 2025) Obeng-Gyasi, Barnabas; Chinthala, Anoop S.; Christodoulides, Alexei; Ordaz, Josue; Mao, Gordon; Neurological Surgery, School of Medicine
    Introduction: The spontaneous resolution of acute subdural hematoma (aSDH) represents an ill-defined but clinically significant phenomenon in traumatic brain injury (TBI). While surgical evacuation remains the standard of care for significant aSDH, rare cases of spontaneous resolution, termed auto-decompression in literature, suggest alternative pathways of hematoma clearance that warrant further investigation. Case presentation: We discuss the case of a 40-year-old male with background seizure disorder who fell off a ladder. His Glasgow Coma Score (GCS) at presentation was 5. Brain Computed Tomography (CT) scan revealed bilateral aSDH and multiple skull fractures. Within 24 h, his GCS quickly improved to 9 T. Repeat brain CT done 72 h post-trauma showed resolution of the aSDH following non-operative management. Discussion: Spontaneous resolution of bilateral aSDH with rapid neurological improvement is a rare but possible occurrence, often attributed to auto-decompression phenomenon in patients with severe head trauma and specific predisposing factors. Our discussion revolves around this patients presentation with polytrauma, complex skull fractures, history of craniotomy, and acute coagulopathy contributing to the spontaneous resolution of the hematoma. Given the complex nature of TBI and the unpredictable course of recovery, clinicians must remain vigilant in continuously reassessing neurological status. Conclusion: This case discusses the unpredictable nature of TBI and highlights the rapid and unexpected resolution of aSDH in a patient with complex neurosurgical history, coagulopathy, and polytrauma. The findings showcase the problems of polytraumatized patients and exemplify the importance of individualized care even when initial signs indicate poor prognosis.

    The Remote Intradural Migration of Polyethylene Glycol-Based Hydrogel Sealant Following Lumbar Laminectomy: A Case Report
    (MDPI, 2025-02-22) Obeng-Gyasi, Barnabas; Line, Trenton A.; Brown, Whitney; Chinthala, Anoop S.; Kussow, Nathan J.; Mao, Gordon; Neurological Surgery, School of Medicine
    Background/Objectives: Synthetic polyethylene glycol (PEG)-based hydrogel sealants, such as Adherus, are commonly used in spinal surgeries to achieve watertight dural closure and prevent cerebrospinal fluid (CSF) leaks. This case report describes an unusual instance of suspected hydrogel sealant migration resulting in an intradural collection at a spinal level remote from the original surgery. Methods: A 57-year-old female with a history of osteoarthritis and prediabetes underwent a minimally invasive L5-S1 laminectomy for the removal of an epidural abscess causing cauda equina and S1 nerve root compression. During the procedure, a dural puncture occurred, which was repaired using Duragen (collagen matrix) and Adherus (synthetic PEG hydrogel sealant). Postoperatively, the patient developed urinary retention and new bilateral posterior leg pain. An MRI on postoperative day four revealed a new peripherally enhancing dorsal intradural collection at the L2 level, causing significant thecal sac narrowing and compression of the cauda equina nerve roots, suggestive of migration of the hydrogel sealant used during surgery. Conservative management was adopted. Results: The patients symptoms gradually resolved. Follow-up imaging at five months showed resolution of the intradural collection, with residual intradural inflammatory changes and arachnoiditis. Conclusions: While PEG-based hydrogel sealants like Adherus are effective in preventing CSF leaks, they can, in rare instances, migrate and cause remote intradural collections with neurological symptoms. Surgeons should exercise meticulous application techniques, thoroughly document the use of sealants, and maintain vigilant postoperative monitoring to mitigate these risks.
