The dural tail sign is often the pathological presence of meningiomas and recently reckoned as a response to vascular congestion and edema. Zero echo time (ZTE) imaging is capable of capturing signal of tissues with relatively short T2* such as pia mater right after onset of the radiofrequency pulse. The significant enhanced rim of meningioma on ecZTE showed the meningioma were supplied by both intracranial and extracranial arteries. Contrast-enhanced ZTE might be listed as a routine imaging sequence to improve accuracy of discriminating the tumor-cortex-dura interface and offer additional clinical information such as vascular growth and supply in meningiomas.
