A nosebleed, also known as epistaxis, is an instance of bleeding from the nose. [1] Blood can flow down into the stomach, and cause nausea and vomiting. [8] In more severe cases, blood may come out of both nostrils. [9] Rarely, bleeding may be so significant that low blood pressure occurs. [1]
In adults, the most common symptom of meningitis is a severe headache, occurring in almost 90% of cases of bacterial meningitis, followed by neck stiffness (the inability to flex the neck forward passively due to increased neck muscle tone and stiffness). [16]
The pain can ultimately become disabling unless the ambient pressure is reversed. The pressure difference causes the mucosal lining of the sinuses to become swollen and submucosal bleeding follows with further difficulties ventilating the sinus, especially if the orifices are involved. Ultimately fluid or blood will fill the space.
The bleed can be very small without any significant effect on surrounding brain or large hemorrhage that exerts mass effect on adjacent brain. Follow up CT scan is recommended. Those with extension of bleed into the ventricular system, expansion of bleeding, or increasing cerebral oedema on CT scan gives poorer prognosis. CT angiography (CTA ...
Head injury may be associated with a neck injury. Bruises on the back or neck, neck pain, or pain radiating to the arms are signs of cervical spine injury and merit spinal immobilization via application of a cervical collar and possibly a longboard. If the neurological exam is normal this is reassuring.
Nine in ten people with cerebral venous thrombosis have a headache; this tends to worsen over the period of several days, but may also develop suddenly (thunderclap headache). [3] The headache may be the only symptom. [5] Many have symptoms of stroke: inability to move one or more limbs, weakness on one side of the face or difficulty speaking ...
Cerebral edema is a severe complication of acute brain injuries, most notably ischemic stroke and traumatic brain injuries, and a significant cause of morbidity and mortality. [ 3 ] [ 10 ] [ 34 ] Cerebral edema is the cause of death in 5% of all patients with cerebral infarction and mortality after large ischemic strokes with cerebral edema is ...
