Pain in one or two branches of the trigeminal nerve
Introduction
Introduction The clinical manifestations of cavernous sinus meningioma may have pain in the first or second branch of the trigeminal nerve. The cavernous sinus is a relatively complex and complex anatomical region of the skull that contains important arteries and cranial nerves. Broadly speaking, all meningiomas that invade the cavernous sinus belong to this category. Such as sphenoid ridge medial meningioma, saddle nodule meningioma, middle cranial meningioma. The occurrence of the disease is related to certain internal environmental changes and genetic variation, not caused by a single factor, and may be related to factors such as craniocerebral trauma, radiation exposure, viral infection, and bilateral auditory neuroma.
Cause
Cause
From the cavernous sinus outer wall tumor, pituitary tumor, sphenoid tumor and cavernous sinus thrombophlebitis, cavernous sinus aneurysm, etc. caused by III, IV, VI, V (1, 2) cranial nerve palsy. The occurrence of meningioma may be related to certain internal environmental changes and genetic variation, not caused by a single factor, and may be related to factors such as craniocerebral trauma, radiation exposure, viral infection, and bilateral auditory neuroma.

Clinical manifestations may have headaches, III to VI cranial nerve palsy, more prominent eyeballs, pain in the first or second branch of the trigeminal nerve. Headache may be an early symptom of the disease. A considerable number of patients have headaches accompanied by cranial nerve palsy of III, IV and V. Ocular numbness appears earlier, and the tumor is located in the supracondylar sac or directly stimulates the trigeminal ganglion, which is prone to severe pain in the first and second branches of the trigeminal nerve. Changes in visual field of vision are also common early clinical manifestations.
Diagnosis
Differential diagnosis
Most trigeminal neuralgia starts at the age of 40, mostly in middle-aged and elderly people, especially in women. The disease is in the area of the trigeminal nerve in the head and face, sudden onset, sudden arrest, lightning, knife cutting, burning, refractory, unbearable severe pain.
Headaches, such as the cause of the headache, the course of the disease, the time, location, nature, extent, and causes of exacerbations and alleviations, may provide some clues or directions for the cause. Such as superficial acupuncture-like sharp pain, multi-cranial neuropathic pain, pulsating pain or pain in one side is vascular pain, and contraction pain and pain in the neck occipital, frontal, etc. are muscle contraction Headache and so on. Among them, it is especially important to find out whether the headache is paroxysmal (with a period of complete painlessness) or persistent (may be sometimes light and sometimes heavy), because once it is clear that it is a seizure headache, if you know the cause of the attack at the same time, you can Greatly narrow the scope of exploring the cause and find out the direction of diagnosis as soon as possible.
