Olfactory neuroblastoma is often misdiagnosed pathologically. The authors reviewed eight such cases in which the pathological findings met strict criteria. These neoplasms are locally invasive in the nose and paranasal sinuses, with frequent intraorbital and intracranial extension as well as distant metastases. A rare primary presentation in the sphenoid sinus-clivus region is described. Computed tomography is the procedure of choice in defining intraorbital extension and is complementary to precision laminagraphy for defining intracranial extension. Angiography frequently shows hypervascularity and may be of further help in assessing intracranial extension.
嗅神经母细胞瘤在病理上常被误诊。作者回顾了8例病理结果符合严格标准的此类病例。这些肿瘤在鼻腔和鼻窦局部浸润，常向眶内和颅内扩展以及发生远处转移。本文描述了蝶窦 - 斜坡区域一种罕见的原发表现。计算机断层扫描是确定眶内扩展的首选检查方法，对于确定颅内扩展而言，它是精确体层摄影的补充。血管造影常显示血管丰富，可能有助于进一步评估颅内扩展。
