Abstract
Purpose: Histological confirmation of glioblastoma (GB) is essential for therapeutic planning, even in inoperable cases where stereotactic needle biopsy (STNB) is the only option. However, post-procedural bleeding remains a known risk. This study aimed to evaluate the association between MRI features of GB and hemorrhagic complications following STNB.
Methods: This retrospective, single-center study included 78 patients with IDH-wildtype GB (mean age: 61 years; 33 females) who underwent pre-biopsy MRI (including SWI and DSC-perfusion) and post-biopsy CT within 72 h. Lesions were anatomically classified into four groups based on their location: cortical/superficial grey matter (sGM n = 12), subependymal white matter (sWM; n = 36), deep nuclei/thalamus (n = 26), or brainstem (n = 4). Hemorrhage incidence and area were correlated with lesion location, intratumoral susceptibility signal (ITSS) grade, rCBVmax values, and peritumoral edema. Clinical outcomes were also recorded.
Results: Hemorrhage incidence significantly differed by lesion location (p = 0.009), with the highest frequency in deep lesions (85%). Most non-hemorrhagic cases (53%) occurred in sWM. While rCBVmax did not correlate with hemorrhage incidence, a significant linear association with hemorrhage area was noted (p = 0.016, r = 0.331). Grade 3 ITSS lesions showed more extensive bleeding. No correlation was found between peritumoral edema and bleeding. Most hemorrhages were asymptomatic; only two patients experienced transient neurological symptoms.
Conclusions: Lesion location was the strongest predictor of post-biopsy hemorrhage. The absence of correlation between rCBVmax and bleeding risk suggests biopsies can be safely performed even in hyperperfused (and potentially more aggressive) tumor areas. STNB remains a safe and valuable diagnostic tool when appropriate preoperative evaluation and postoperative monitoring are ensured.
期刊介绍:
Neuroradiology aims to provide state-of-the-art medical and scientific information in the fields of Neuroradiology, Neurosciences, Neurology, Psychiatry, Neurosurgery, and related medical specialities. Neuroradiology as the official Journal of the European Society of Neuroradiology receives submissions from all parts of the world and publishes peer-reviewed original research, comprehensive reviews, educational papers, opinion papers, and short reports on exceptional clinical observations and new technical developments in the field of Neuroimaging and Neurointervention. The journal has subsections for Diagnostic and Interventional Neuroradiology, Advanced Neuroimaging, Paediatric Neuroradiology, Head-Neck-ENT Radiology, Spine Neuroradiology, and for submissions from Japan. Neuroradiology aims to provide new knowledge about and insights into the function and pathology of the human nervous system that may help to better diagnose and treat nervous system diseases. Neuroradiology is a member of the Committee on Publication Ethics (COPE) and follows the COPE core practices. Neuroradiology prefers articles that are free of bias, self-critical regarding limitations, transparent and clear in describing study participants, methods, and statistics, and short in presenting results. Before peer-review all submissions are automatically checked by iThenticate to assess for potential overlap in prior publication.
