Radiological and Pathological Features:
MRI with gadolinium remains the diagnostic cornerstone, typically revealing T1 hypointensity, T2
hyperintensity, and heterogeneous enhancement with necrotic or hemorrhagic components [5]. Leptomeningeal
dissemination is present in up to 40% of cases, mandating neuraxis-wide MRI and, when feasible, cerebrospinal
fluid (CSF) cytology [5]. Our case lacked craniospinal staging, representing a limitation.
Histomolecular profiling is increasingly recognized as indispensable. Many pediatric scGBMs harbor H3 K27
alterations, categorizing them as diffuse midline gliomas (DMG) with uniformly poor prognosis [6]. Additional
recurrent alterations include TP53 mutations and PDGFRA amplification, while actionable mutations such as
BRAF V600E or NTRK fusions—although rare—offer potential for targeted interventions [7,8]. The absence
of molecular testing in the present case precluded definitive classification and trial eligibility, limiting
therapeutic opportunities.
Therapeutic Strategies:
Maximal safe resection remains the primary therapeutic intervention, aiming to relieve mass effect and preserve
function. However, true gross total resection is achieved in a minority of cases due to the infiltrative nature of
scGBM and eloquent tumor location. Intraoperative neurophysiological monitoring is recommended to minimize
morbidity [9,10].
Adjuvant radiotherapy represents the cornerstone of postoperative management and has been shown to
significantly prolong survival compared with surgery alone. Conformal techniques, including intensity-
modulated radiotherapy (IMRT) and proton beam therapy, allow delivery of adequate tumoricidal doses within
spinal cord tolerance [11]. Craniospinal irradiation is considered in cases with leptomeningeal dissemination
[12].
The Stupp regimen—radiotherapy with concomitant temozolomide followed by adjuvant temozolomide—
remains the most widely adopted systemic therapy, though pediatric-specific evidence is limited [13]. Recent
meta-analyses suggest modest benefit when combined with radiotherapy [1]. Novel therapeutic avenues under
investigation include epigenetic modulators, such as panobinostat, and immune checkpoint inhibitors,
particularly for H3 K27-altered tumors [7,14].
The most recent meta-analysis with Da Cunha et al[1] demonstrated that patients receiving multimodal therapy
(surgery plus radiotherapy ± chemotherapy) had superior survival compared with surgery alone (median PFS
15.2 vs. 2.1 months), with a consistent overall survival advantage across series [1]. By contrast, our patient,
treated without adjuvant therapy, experienced rapid decline and represents the poorest-prognosis subgroup,
aligning with the literature.
In addition to disease-directed therapies, postoperative supportive management is critical—particularly for
cervicomedullary lesions with high risk of respiratory failure. Evidence supports proactive strategies including
close respiratory monitoring, early tracheostomy when indicated, intensive physiotherapy, nutritional support,
and prevention of infectious complications [5,10]. Such measures may improve short-term survival and quality
of life. The rapid respiratory deterioration observed in our case highlights the importance of early
multidisciplinary supportive interventions.
Recent systematic reviews and meta-analyses [1–3] reinforce several recurring themes: the extreme rarity and
aggressiveness of pediatric scGBM, survival advantage with radiotherapy and combined chemoradiation, strong
prognostic weight of cervical location and leptomeningeal dissemination, and the crucial role of histomolecular
profiling to refine diagnosis and guide therapy. Our case exemplifies the poor outcomes observed in patients
treated with surgery alone, underscoring the pressing need for standardized multimodal protocols.
CONCLUSION
Primary pediatric spinal cord glioblastoma remains a devastating malignancy with poor prognosis. This case
highlights the prognostic weight of tumor location and the limitations of surgery alone. Contemporary
