Among the 18 patients, total resection was achieved in 16 cases, subtotal resection in 1 case, and biopsy in 1 case.

While effective for seizure control, these neurosurgical interventions can produce significant functional deficits including hemiparesis and iatrogenic cerebral palsy. In this study, we aim to evaluate the resulting MSK pathology following surgery for DRE so that we may establish the incidence of new MSK pathology, identify risk factors for developing MSK pathology, and guide orthopaedic follow-up care. Methods A retrospective chart review of 168 pediatric patients who underwent a brain hemispherectomy, hemispherotomy, or lobectomy between 2009 and 2018 was performed. Data including pre-existing neurological and orthopaedic conditions, presence of MSK pathology that emerged post-neurosurgical procedure, documented referral to orthopaedics, and postoperative interventions were collected. A multivariate logistic regression model was used to correlate predictive variables with the risk for developing new MSK pathology. Results Of the 168 patients included, 45.2% (n=76) developed a new MSK condition post-operatively. Of those with new MSK pathology, 30.3% (23) received orthopaedic follow-up. Of those, 34.8% (8) underwent a subsequent orthopaedic surgery. The median time to diagnosis of emerging MSK pathology following neurosurgical intervention was 0.7 months (range: 0-128 months), while the median time from emergence of symptoms to orthopaedic follow-up was 9.5 months (range: 2-161 months). Of the 28 patients who had MSK pathology prior to neurosurgical intervention, 42.8% (n=12) were seen by orthopaedic providers following neurosurgery, of which 58.3% (n=7) required orthopaedic surgery. Older age at the time of initial neurological surgery was significantly associated with decreased risk for developing new postoperative MSK pathology (OR 0.985, 95% CI 0.979 - 0.911, p<0.001), while repeat or revision neurosurgery was associated with increased risk (OR 3.728 95% CI 1.530-9.083, p<0.01). Conclusion Pediatric patients who undergo hemispherectomies, hemispherotomies or lobectomies for DRE are subject to a significant post-operative burden of MSK disease, yet less than 1/3 of newly-affected patients receive orthopaedic follow-up - highlighting a gap between the need for and provision of orthopaedic care in this population.</p>","PeriodicalId":54631,"journal":{"name":"Pediatric Neurosurgery","volume":" ","pages":"1-15"},"PeriodicalIF":0.9,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143588293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tumor was primarily diagnosed as an ependymoma of the spinal cord. Prior to her transfer to our department, the patient had undergone subtotal resection of the lesion, radiation therapy, multiple chemotherapy regimens, and biopsy of the recurrent tumor. Clinically, the patient presented with tetraparesis and had recently experienced worsening upper extremity weakness with complete loss of hand function. We performed a near total resection of the recurrent tumor. Ultra-fast Nanopore seq® based DNA methylome profiling allowed confirmation of the molecular diagnosis of a high-grade neuroepithelial tumor (HGNET-MN1) consistent with astroblastoma in less than 2 h, with subsequent molecular workup revealing a EWSR1-BEND2 fusion. After surgery, the patient gradually regained function in her hands. She was sent to a specialized pediatric rehabilitation center, and while the tumor was being followed radiologically with no adjuvant treatment planned, the patient presented with a relapse of the tumor in only 3 months.
