Oncocytic neoplasms result from metabolically altered cells that accumulate abundant mitochondria within their cytoplasm by oncocytic metaplasia. In this report, the CT findings are described and correlated with the histopathologic features of a case of oncocytoma involving the parotid gland that arose in a background of nodular oncocytic hyperplasia. When imaging demonstrates multiple small nodules in the parotid gland with a large, solid, or cystic mass, the diagnosis of oncocytic neoplasia should be considered.
嗜酸性细胞瘤由代谢改变的细胞产生，这些细胞通过嗜酸性化生在其细胞质内积聚大量线粒体。在本报告中，描述了一例发生在结节性嗜酸性细胞增生背景下的腮腺嗜酸性细胞瘤的CT表现，并将其与组织病理学特征相关联。当影像学显示腮腺内有多个小结节以及一个大的实性或囊性肿块时，应考虑嗜酸性细胞瘤的诊断。
