Abstract：
Sinoliths are mineral deposits that occur within the paranasal sinus due to long-standing obstruction and lack of drainage. It is a rare differential diagnosis for intrasinus lesions found on imaging. On computed tomography (CT) of the head, these calcifications are visualized as dense radiopaque bodies within the sinuses. Typically, patients with sinoliths are asymptomatic, but if complications of chronic obstruction and recurring sinusitis arise, endoscopic removal of the sinolith may be recommended. Here, we present a 95-year-old female found to have a sinolith in the sphenoid sinus on incidental imaging. This report discusses the etiology, pathophysiology, clinical presentation, radiologic findings, and management of sinoliths.
摘要：
鼻窦是由于长期阻塞和缺乏引流而发生在鼻旁窦内的矿物质沉积物。对于影像学发现的血管内病变，这是一种罕见的鉴别诊断。在头部的计算机断层扫描(CT)上，这些钙化在鼻窦内被视为致密的不透射线体。通常,患有鼻石的患者无症状，但是如果出现慢性梗阻和复发性鼻窦炎的并发症，建议在内镜下切除鼻石.这里,我们介绍了一名95岁的女性，在偶然成像中发现蝶窦有鼻窦。本报告讨论了病因，病理生理学,临床表现,放射学发现，和神力管理。
