Dural tail sign positive tumors: Points to make a differential diagnosis

Radiol Case Rep. 2023 Dec 4;19(2):773-779. doi: 10.1016/j.radcr.2023.10.054. eCollection 2024 Feb.

Abstract

Representative patients were treated with total surgical mass resection, and each tumor was histopathologically confirmed to have a secretory meningioma, intradural metastasis of gynecologic origin, and dural metastasis of lung origin. The imaging findings of these patients were inconclusive in differentiating meningioma from metastasis; hence, advanced magnetic resonance imaging (MRI) techniques were considered. Based on these reports, we studied how to differentiate typical meningiomas from atypical and malignant meningiomas and other dura-based malignant tumors using conventional computed tomography and MRI.
