CT findings in multicentric glioblastoma: diagnostic-pathologic correlation

Summary
Diagnosing multicentric glioblastoma can be challenging using computerized cranial tomography (CCT) and angiography. Definitive diagnosis of this brain tumor type often requires pathological confirmation, typically through autopsy.
Area of Science:
- Neuro-oncology
- Neuroradiology
- Pathology
Background:
- Multicentric glioblastoma presents diagnostic challenges, often mimicking other intracranial pathologies.
- Accurate differentiation is crucial for appropriate patient management and treatment planning.
Observation:
- Computerized cranial tomography (CCT) and angiography were used to evaluate three cases of multicentric glioblastoma.
- Radiological findings, including mass effect and tumor neovascularity, were assessed.
- Differentiation from metastatic disease or abscesses proved difficult on imaging alone.
Findings:
- CCT and angiography provided limited definitive diagnostic information for multicentric glioblastoma.
- Angiography showed mass effect in one case and tumor neovascularity in another, but lacked specificity.
- Pathological examination, including biopsy and autopsy, was essential for confirming the diagnosis.
Implications:
- Advanced imaging techniques may not always distinguish multicentric glioblastoma from other lesions.
- Multicentric glioblastoma diagnosis relies heavily on histopathological confirmation.
- Autopsy remains critical for definitively characterizing the multifocal or multicentric nature of glioblastomas.
