摘要
目的探讨MSCT对涎腺非肿瘤性疾病的诊断和鉴别诊断价值。方法33例涎腺非肿瘤性疾病行MSCT平扫和增强扫描后,将MSCT诊断与病理结果作对照研究,包括病灶边界、形态、是否强化等。结果病灶边界清楚18例,边界模糊15例,椭圆形或类圆形27例,不规则形6例,实性病变平扫呈稍低密度,增强轻或中度强化,囊性病变平扫囊壁呈等或稍低密度,无强化或轻度强化,中央无明显强化;病变继发感染边缘模糊不清,强化较明显。结论MSCT对涎腺非肿瘤性疾病的诊断和鉴别诊断有一定特点。
Objective To discuss the role of MSCT in the diagnosis and differential diagnosis of non - neoplastic lesions of salivary gland. Methods The MSCT findings of 53 patients with non - neoplastic lesions of salivary gland proven pathologically were analyzed retrospectively. MSCT plain - scan and enhanced - scan were performed in all the cases. Results There were 18 cases with well defined margin and 15 eases with hazy border. 27 cases were oval or oblong, and 6 cases were irregular shape. Solid lesion plain - scan showed slightly hypodense, mild or moderate enhancement, wall of the cystic lesion with isodense or slightly hypodense, no or mild enhancement, no enhancement in the center of the lesion. Secondary infective lesion showed indistinct border and significant enhancement. Conclusion MSCT plays important role in the diagnosis and differential diagnosis of non - neoplastic lesions of salivary gland .
