1. Clinical presentation and history taking
A detailed history is obtained regarding headache, projectile vomiting, neurological deficits, and forced head posture, providing clues for tumor localization.
2. Neurological examination
Cranial nerves, coordination, motor and sensory function, and reflexes are assessed to determine the extent of neurological involvement.
3. Magnetic resonance imaging (MRI)
The first-line core modality: non-contrast sequences demonstrate cystic change and edema, while contrast-enhanced imaging evaluates enhancement patterns and involvement of adjacent structures.
4. Whole-brain and whole-spine MRI screening
Mandatory to assess cerebrospinal fluid dissemination and to guide decisions on radiotherapy field coverage.
5. Computed tomography (CT)
Provides rapid emergency assessment of calcification, hemorrhage, and acute hydrocephalus, serving as a complementary modality.
6. Histopathological biopsy and diagnosis
Microscopic examination of surgical or biopsy specimens is the gold standard. Perivascular pseudorosettes are a characteristic feature, and WHO grading is established.
7. Molecular pathology testing
DNA methylation profiling enables precise molecular classification (e.g., PFA/PFB, ZFTA fusion) and supports prognostic stratification.
8. Cerebrospinal fluid cytology
Lumbar puncture is performed postoperatively or after risk assessment; detection of exfoliated tumor cells provides confirmatory evidence of dissemination.
9. Daily self-check for ependymoma
The public should remain vigilant for progressively worsening headache, vomiting, gait abnormalities, limb weakness, and bowel or bladder changes and seek medical evaluation promptly.
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that delayed diagnosis of ependymoma can lead to irreversible neurological injury and dissemination. Early and accurate diagnosis is a lifeline: vigilance for neurological warning signs and timely diagnosis through MRI, pathology, and molecular subtyping are essential. Accurate subtyping is the fundamental prerequisite for individualized surgery and comprehensive treatment and for improving outcomes.
