目的探讨64排螺旋CT诊断上颌窦癌的价值。方法回顾性分析35例经手术组织病理证实的上颌窦癌患者64排螺旋CT影像资料。结果上颌窦癌CT表现为上颌窦内软组织肿块影,并向周围组织侵袭,增强后可见不均匀强化,窦壁多呈溶骨性破坏;64排螺旋CT TNM分期符合率为97.1%(34/35),判断邻近结构受侵符合率为96.2%(101/105)。结论 64排螺旋CT多平面重建诊断上颌窦癌符合率高,可显示病变范围,对指导治疗及TNM分期有重要价值。
Objective To investigate the value of 64-slice spiral CT in the diagnosis of maxillary sinus cancer. Methods The data of 64 spiral CT images of 35 patients with maxillary sinus cancer proved by operation histopathology were retrospectively analyzed. Results The maxillary sinus cancer showed maxillary sinus soft tissue mass and invasion to the surrounding tissues. The enhanced sinusoidal heterogeneity was observed and the sinus wall mostly showed osteolytic destruction. The coincidence rate of 64-slice spiral CT TNM staging was 97.1% (34 / 35). The coincidence rate of adjacent structures was 96.2% (101/105). Conclusion 64-slice spiral CT multiplanar reconstruction diagnosis of maxillary sinus cancer with a high coincidence rate can show the extent of the disease, the guiding treatment and TNM staging has important value.
