目的通过对垂体瘤患者的MRI影像学资料进行回顾性研究,结合患者的神经眼科学表现,进一步探讨垂体瘤致视力下降的原因.方法以手术治疗的48例垂体瘤患者为研究对象,回顾性分析其临床资料,通过对垂体瘤的MRI影像学特征进行研究,观察肿瘤与颈内动脉床突上段(C2段)的关系,结合垂体瘤患者的神经眼科学表现,分析肿瘤特点与视力损害的关系.结果从MRI冠状位上观察,48例垂体瘤患者有28侧(29.2%)颈内动脉C2段受累,受累侧视力下降平均值为O.80±0.20(0.40～1.00),68侧(70.8%)颈内动脉C2段未受累,视力下降平均值为0.30±0.30(0.00～1.00),2组视力下降平均值差异有统计学意义(P<O.05).结论颈内动脉C2段受累则该侧视力下降往往较严重,可能是由肿瘤累及该段发出的视交叉动脉引起.

Objective To demonstrate the cause of visual loss (VL) caused by pituitary adenomas (PAs),through retrospective study on the magnetic resonance imaging (MRI) radiological materials of patients with PAs.Methods Forty eight patients with PAs were selected,who received surgical treatment at our Hospital.Their medical records and MRI radiological films were reviewed.The relationship between the characteristics of PAs and the visual deterioration were analyzed.Neuro-ophthalmological findings were elevated with the relationship between the tumor and the supraelinoidal segment (C2 segment) of the internal carotid artery(ICA).Resuits On the coronal MR images,C2 segments of 28 sides(29.2%) were involved by the tumors whose value of VL in the ipsilateral eyes averaged 0.80±0.20 (range from 0.40 to 1.00).In the rest 68 sides (70.8%) without C2 segments involved,the valHe of VL in the correspondent eyes averaged 0.30±0.30 (range from 0.00 to 1.00).The difference was statistically significant (P<0.05).Conclusions If the C2 segment of ICA is invaded,the worse visual acuity would appear.which might be due to the markedly involved chiasmal arteries.
