What is seno cavernoso?

Seno cavernoso is a paired blood-filled space located on each side of the sella turcica of the skull base. It is a complex structure that is surrounded by various nerves and blood vessels, such as the internal carotid artery, cranial nerves III, IV, V1, V2, and VI, and the cavernous sinuses. The seno cavernoso serves as a pathway for various structures that enter and exit the skull along with the surrounding structures. Additionally, the region serves as a location for the formation of blood clots, tumors, and infection, which may result in various symptoms such as headache, vision problems, and facial pain. Due to its location and proximity to vital structures, the seno cavernoso is of immense clinical significance.
