Abstract
We describe a rare case and novel management strategy of painful trigeminal neuropathy caused by an arachnoid cyst confined to Meckel's cave. A 57-year-old female presented with several years of progressive trigeminal pain and signs of trigeminal deafferentation, including sensory loss, corneal anesthesia and mastication muscle atrophy. Medical treatment with carbamazepine provided partial and temporary pain control. Surgical treatment was eventually performed by aspiration of the arachnoid cyst through the foramen ovale using a percutaneous approach. The patient experienced relief of pain and improvement of numbness and muscle strength. To our knowledge, this is the first case description of a percutaneous drainage of a Meckel's cave arachnoid cyst.
