The related symptoms were resolved by decreasing the intracranial pressure. As in our case, symptom relief can predict a good prognosis in these cases, resulting in an improved quality of life. Although it is not frequently reported, this potential association can be significant as resolving intracranial hypertension can easily improve the symptoms in those suffering from this condition.To our knowledge, no relationship between increased intracranial pressure and trigeminal neuralgia had yet been reported in the literature. https://crcp.tums.ac.ir/index.php/crcp/article/view/673
