Imaging of perineural spread in head and neck tumours.

Ong CK, Chong VF - Cancer Imaging (2010)

Bottom Line: Perineural tumour spread refers to a contiguous neoplastic extension along a nerve.This article focuses on the imaging features of perineural spread of head and neck tumours.The important potential perineural pathways and the possible underlying pathogenesis of this phenomenon are also reviewed.

ABSTRACT
Perineural tumour spread refers to a contiguous neoplastic extension along a nerve. As it may be clinically silent, imaging plays a pivotal role in the evaluation and delineation of perineural infiltration in head and neck malignancies, which in turn affects treatment planning. This article focuses on the imaging features of perineural spread of head and neck tumours. The important potential perineural pathways and the possible underlying pathogenesis of this phenomenon are also reviewed.

Centripetal perineural spread. Axial contrast-enhanced T1-weighted images show (a) an en-plaque meningioma along the lateral wall of the left cavernous sinus and tentorial leaf (arrows), with (b) centripetal perineural spread to the trigeminal ganglion in the Meckel cave (white arrow) and the cisternal segment of the trigeminal nerve (black arrow).

Figure 2: Centripetal perineural spread. Axial contrast-enhanced T1-weighted images show (a) an en-plaque meningioma along the lateral wall of the left cavernous sinus and tentorial leaf (arrows), with (b) centripetal perineural spread to the trigeminal ganglion in the Meckel cave (white arrow) and the cisternal segment of the trigeminal nerve (black arrow).

Mentions: Perineural tumours typically extend centripetally toward the brain, although centrifugal spread is not uncommonly seen (Figs. 2 and 3).Figure 2
