The biopsy and the decompression of a pilocytic (juvenile) astrocytoma of the optic nerve may caused increased mucoid formation and increased meningothelial reaction (meningioma formation) and therefore expansion of the tumour remnants. Experiences in the literature and our own clinical, histological and electrron microscopic observations are proof of this thesis. The correct diagnosis is easily established clinically. We should remain conservative if there is no necessity to intervene. A subtotal excision may be harmful.
视神经毛细胞型（青少年型）星形细胞瘤的活检及减压可能会导致黏液样形成增加和脑膜内皮反应（脑膜瘤形成）增加，从而使肿瘤残余物扩大。文献中的经验以及我们自己的临床、组织学和电子显微镜观察都证实了这一论点。临床上很容易做出正确诊断。如果没有干预的必要，我们应保持保守。次全切除可能有害。
