Although neurovascular compression is often associated with trigeminal neuralgia, other intracranial pathologies can result in compression along the nerve.
CASE DESCRIPTION: The authors report a case of a patient suffering from a typical left trigeminal neuralgia affecting both the second and the third branches. Neuroradiological examinations showed the presence of an arachnoid cyst located in the left temporal lobe, contiguous with the Meckel’s cave, eroding the greater wing of the sphenoid bone. Following a meticulous decision-making process the patient underwent conservative treatment with success. A properly modulation of the drug dosage allowed pain relief to be achieved.
CONCLUSION: This is a rare case reporting a typical trigeminal neuralgia by an arachnoid cyst of the Meckel’s cave mimicking a neurovascular compression syndrome. Our findings, behind the review of the current literature, point out the importance of such a pathological condition when dealing with patients affected by cranial nerve dysfunction syndrome.
