[Pure spinal epidural cavernous hemangioma: report of one case].

A 55-year-old man presented with progressive numbness and weakness of both lower limbs is reported. MRI demonstrated a pure epidural lesion at T3-6 space appearing as isointense on T1-weighted images with enhancement by contrast medium and hyperintense on T2-weighted images. The lesion was totally removed microsurgically. Histological examination revealed cavernous hemangioma. The patient made a good recovery after surgery.

[Correlation of influencing factors with the extent of peritumoral brain glioma edema].

OBJECTIVE: To explore the correlation of various influencing factors with the extent of peritumoral brain glioma edema. METHODS: A total of 69 glioma cases were confirmed by pathology after operation. And stepwise multiple linear regression analysis was performed on gender, age, Karnofsky performance scale (KPS) score, onset to treatment time, tumor size, location, shape and WHO pathological grade. RESULTS: All of them had peritumoral edema. The relevant factors included pathology grading, onset to treatment time, KPS score and age. The data were entered into the regression equation of edema index. The partial regression coefficients were 0.853, 0.456, -0.352 and 0.291 respectively (P < 0.01). CONCLUSION: Peritumoral brain edema in glioma patients are correlated with WHO pathologic grading, onset to treatment time, KPS score and age. But it has no correlation with patient gender, tumor location, tumor size and shape.
