brain stem herniation: quick shallow respirations followed by period of apnea Bitot's spots: Pierre Bitôt: ophthalmology: vitamin A deficiency: spots of keratin deposition in the conjunctiva Bjerrum scotoma: Jannik Peterson Bjerrum: ophthalmology: glaucoma: comet shaped visual field defect, extending temporally from the physiological blind ...
Brain herniation is a potentially deadly side effect of very high pressure within the skull that occurs when a part of the brain is squeezed across structures within the skull. The brain can shift across such structures as the falx cerebri , the tentorium cerebelli , and even through the foramen magnum (the hole in the base of the skull through ...
Cerebral contusion (Latin: contusio cerebri), a form of traumatic brain injury, is a bruise of the brain tissue. [2] Like bruises in other tissues, cerebral contusion can be associated with multiple microhemorrhages, small blood vessel leaks into brain tissue. Contusion occurs in 20–30% of severe head injuries.

The symptoms of brain stem tumors vary greatly and can include ataxia, cranial nerve palsy, headaches, problems with speech and swallowing, hearing loss, weakness, hemiparesis, vision abnormalities, ptosis, and behavioral changes. Another possible symptom is vomiting.
Undifferentiated cancer cells typically don’t look or behave like the normal cells in tissues where they develop and may not produce much PSA. Prostate cancer is one of the most curable diseases ...
CT scan (computed tomography) of the brain (without any iodinated contrast), is the initial imaging choice because of its high speed, good accessibility in hospitals, high sensitivity in detecting brain injuries or brain diseases, thus helping to triage patients in emergency department in a timely manner and urgent neurosurgical intervention ...
A study looking at ultra-detailed MRI scans of people hospitalized with severe COVID-19 found that the disease affects the brainstem, a region of the brain responsible for controlling many key ...
The risk of death from an intraparenchymal bleed in traumatic brain injury is especially high when the injury occurs in the brain stem. [48] Intraparenchymal bleeds within the medulla oblongata are almost always fatal, because they cause damage to cranial nerve X, the vagus nerve , which plays an important role in blood circulation and ...
