The conundrum of a resolving cavernous sinus syndrome
A middle-aged lady who presented with headaches and sudden onset of left cavernous sinus syndrome was found to have a left persistent primitive trigeminal artery (PPTA) on scans. The syndrome uniquely resolved spontaneously after a few days. Vascular variations in the region of the cavernous sinus should be actively sought in cross-sectional imaging performed for cavernous sinus syndrome.
