Occipital neuralgia is caused by damage to the occipital nerves, which can arise from trauma (usually concussive or cervical), physical stress on the nerve, repetitive neck contraction, flexion or extension, and/or as a result of medical complications (such as osteochondroma, a benign bone tumour).
Lack of CSF pressure and volume can allow the brain to sag and descend through the foramen magnum (large opening) of the occipital bone, at the base of the skull. The lower portion of the brain is believed to stretch or impact one or more cranial nerve complexes, thereby causing a variety of sensory symptoms. Nerves that can be affected and ...
In humans, the epicranial aponeurosis originates from the external occipital protuberance and highest nuchal lines of the occipital bone. [1] It merges with the occipitofrontalis muscle. In front, it forms a short and narrow prolongation between its union with the frontalis muscle (the frontal part of the occipitofrontalis muscle).
Neck-tongue syndrome (NTS), which was first recorded in 1980, [1] is a rare disorder characterized by neck pain with or without tingling and numbness of the tongue on the same side as the neck pain. [2] Sharp lateral movement of the head triggers the pain, usually lasting from a few seconds to a few minutes. Headaches may occur with the onset ...
The occipital bone overlies the occipital lobes of the cerebrum. At the base of the skull in the occipital bone, there is a large oval opening called the foramen magnum, which allows the passage of the spinal cord. Like the other cranial bones, it is classed as a flat bone. Due to its many attachments and features, the occipital bone is ...
The swelling may obscure the fontanel and cross cranial suture lines, distinguishing it from cephalohematoma, [2] in which the bleed is confined by its subperiosteal location. [3] Patients with subgaleal hemorrhage may also have significant hyperbilirubinemia due to resorption of hemolyzed blood. Laboratory studies may demonstrate reduced ...
The greater occipital nerve is a nerve of the head. It is a spinal nerve , specifically the medial branch of the dorsal primary ramus of cervical spinal nerve 2 . It arises from between the first and second cervical vertebrae , ascends, and then passes through the semispinalis muscle .
Lesions can be due to occipital cortical dysplasia, which can be difficult to identify and diagnose based on an MRI. Most commonly, the disorder is due to idiopathic occipital epilepsies in childhood, and other rare syndromes affecting the occipital area is Sturge-Weber syndrome, adult forms of Rasmussen's syndrome, and more.
