An abnormally growing pituitary adenoma, sitting on the bony sella turcica, will expand in the direction of least resistance and eventually invade the cavernous sinus. [4] Cavernous sinus syndrome may result from mass effect of these tumors and cause ophthalmoplegia (from compression of the oculomotor nerve, trochlear nerve, and abducens nerve ...
Cavernous sinus thrombosis (CST) is the formation of a blood clot within the cavernous sinus, a cavity at the base of the brain which drains deoxygenated blood from the brain back to the heart. This is a rare disorder and can be of two types–septic cavernous thrombosis and aseptic cavernous thrombosis. [ 1 ]
Dorsal midbrain structures, as in Parinaud's syndrome. Certain parts of the cerebral cortex (including the frontal eye fields), as in stroke. Toxic envenomation by mambas, taipans, and kraits. Thiamine deficiency can cause ophthalmoparesis in susceptible persons; this is part of the syndrome called Wernicke encephalopathy. The causal pathway by ...
Direct CCF may be treated by occlusion of the affected cavernous sinus (coils, balloon, liquid agents), or by reconstruction of the damaged internal carotid artery (stent, coils or liquid agents). [citation needed] Indirect CCF may be treated by occlusion of the affected cavernous sinus with coils, liquid agents or a combination of both. [3] [4 ...
Cerebral venous sinus thrombosis (CVST) is a rare form of stroke which results from the blockage of the dural venous sinuses by a thrombus. Symptoms may include headache, abnormal vision, any of the symptoms of stroke such as weakness of the face and limbs on one side of the body and seizures. The diagnosis is usually made with a CT or MRI scan ...
The study, which involved 106 peri- and postmenopausal women and was presented at the Endocrine Society’s annual meeting in May, indicates women should self-monitor their vasomotor symptoms and ...
When Christine Spadafor started to experience frightening symptoms, doctors dismissed her concerns. She was finally diagnosed with an egg-size brain tumor. Woman's symptoms were dismissed as sinus ...
Pulsatile tinnitus is the most common symptom in patients, and it is associated with transverse-sigmoid sinus DAVFs. [1] Carotid-cavernous DAVFs, on the other hand, are more closely associated with pulsatile exophthalmos. DAVFs may also be asymptomatic (e.g. cavernous sinus DAVFs). [2]
