Laryngotracheal amyloid deposition is an uncommon manifestation of systemic light chain amyloidosis. Diagnostic imaging, such as CT, is useful for suggesting the possibility of amyloidosis and delineating the extent of the lesions for surgical management; however, the diagnosis is confirmed with the histologic finding of amorphous eosinophilic material which stains positively for Congo red and may show apple green birefringence on polarization. These features are exemplified in this sine qua non radiology-pathology correlation article.
喉气管淀粉样变沉积是系统性轻链淀粉样变性的一种罕见表现。诊断性影像学检查,如CT,有助于提示淀粉样变性的可能性并描绘病变范围以指导手术治疗;然而,诊断需通过刚果红染色呈阳性且在偏振光下可能显示苹果绿双折射的无定形嗜酸性物质的组织学发现来确诊。这些特征在这篇必不可少的放射学与病理学相关性文章中得到了例证。
