"The key features that are helpful in making the diagnosis are a 'soft' appearing mass centred on the cavernous sinus, with pronounced T2 hyperintensity and contrast enhancement 1-2."
"T1: hypointense to brain"
"T2: markedly high signal intensity"
"Accumulation of 99mTc pertechnetate–labelled red blood cells within the cavernous sinus with scintigraphic imaging techniques is specific for cavernous haemangiomas 3."

"Surgical resection can be challenging due to blood loss, especially if the diagnosis is not suspected pre-operatively, resulting in high intraoperative mortality, up to 12.5% in the literature 2 (although this is probably in large part due to reporting bias)."

"The presentation is usually due to mass effect on adjacent structures (especially cranial nerves within the sinus or the optic pathway). Presenting symptoms include diplopia due to extraocular muscle dysfunction (CN III, CN IV and CN VI) and visual loss (CN II) and facial numbness (CN V) 1. When large the mass can also result in symptoms from mass effect, such as a headache 1."
