Malignant proliferative ependymoma of the neck with lymph node metastasis: A case report

Figure 1 Magnetic resonance imaging scans. A: Hypointense lesion on T1-weighted images; B and C: Predominantly hypointense and hyperintense lesion on T2-weighted images; D: Mixed signal mass on T2 compression lipid sequence, primarily isointense to hypointense; E and F: Notable heterogeneous enhancement of the mass on contrast-enhanced magnetic resonance imaging.

Figure 2 Pathological findings. A: Vigorous tumor growth [hepatic encephalopathy (HE) × 100)]; B: Lymph node metastasis; C: Tumor nests (HE × 50).
