PURPOSE
To determine whether the MR finding of cysts along the intracranial margin of sinonasal esthesioneuroblastomas can be considered to suggest this tumor.
METHODS
MR scans of 54 patients who had sinonasal lesions with intracranial extension were examined specifically for cysts along the intracranial margins of the lesions.
RESULTS
Only 3 of the 54 patients had these cysts, and all 3 of these patients had esthesioneuroblastoma. Surgical pathologic findings of one specimen showed the cyst to be marginally located within the tumor.
CONCLUSION
If cysts are seen on MR along the intracranial margin of a sinonasal mass, this finding highly suggests esthesioneuroblastoma.
目的
确定鼻窦嗅神经母细胞瘤颅内边缘出现囊肿的磁共振成像（MR）表现是否可提示该肿瘤。
方法
对54例有鼻窦病变并伴有颅内扩展的患者进行MR扫描，专门检查病变颅内边缘的囊肿情况。
结果
54例患者中只有3例有这些囊肿，且这3例患者均患有嗅神经母细胞瘤。其中一个标本的手术病理结果显示囊肿位于肿瘤边缘。
结论
如果在MR上看到鼻窦肿物的颅内边缘有囊肿，这一表现高度提示为嗅神经母细胞瘤。
