'Trident sign' in pelvis: sinister sign with poor prognosis

BMJ Case Rep. 2017 Aug 7:2017:bcr2017220460. doi: 10.1136/bcr-2017-220460.

Abstract

The perineural spread of the cancer through the lumbosacral plexus gives an appearance of 'trident sign' on contrast-enhanced CT scan and MRI. It is associated with adverse survival rates and carries a poor prognostic value.

Keywords: cervical cancer; computed tomography; lumbosacral plexopathy; perineural spread.
