The reasons for this state are not fully understood and debatable (discussed by scientists). There is a fairly large number of conditions that can mimic the Tolosa-Hunt syndrome (orbital myositis, infectious inflammation of the outer wall of the cavernous sinus, systemic diseases, brain tumors and orbits, vascular transformations, etc.). Proceeding from this, such a diagnosis should be a “diagnosis of exclusion” (that is, it is set by excluding other possible diseases).
Equally, this disease affects men and women, a high incidence is noted in the elderly and senile age. Clinical manifestations appear rapidly, acutely, without previous symptoms or gradually increasing, after a viral infection that can pass unnoticed, after hypothermia, of stress.
