In addition to tonsillar ectopia, patients with this entity also have caudal descent of the brainstem. A significant proportion of these patients require a second surgery as a result of persistent syringomyelia. [30] [36] Headache and neck pain, similar to Chiari I II This is the only type also known as an "Arnold–Chiari" malformation.
Also called cerebellar tonsillar ectopia, or tonsillar herniation. Although often congenital, Chiari malformation symptoms can also be induced due to physical head trauma, commonly from raised intracranial pressure secondary to a hematoma, or increased dural strain pulling the brain caudally into the foramen magnum.
Ectopic ACTH syndrome, also known as small-cell carcinoma. Ectopic calcification, a pathologic deposition of calcium salts in tissues or bone growth in soft tissues; Cerebellar tonsillar ectopia, aka Chiari malformation, a herniation of the brain through the foramen magnum, which may be congenital or caused by trauma.
[2] [3] Causes of a primary CSF leak are those of trauma including from an accident or intentional injury, or arising from a medical intervention known as iatrogenic. A basilar skull fracture as a cause can give the sign of CSF leakage from the ear, nose or mouth. [4] A lumbar puncture can give the symptom of a post-dural-puncture headache.
Herniation can be caused by a number of factors that cause a mass effect and increase intracranial pressure (ICP): these include traumatic brain injury, intracranial hemorrhage, or brain tumor. [1] Herniation can also occur in the absence of high ICP when mass lesions such as hematomas occur at the borders of brain compartments. In such cases ...
An accessory salivary gland is ectopic salivary gland tissue with a salivary gland duct system. [3] The most common location of accessory salivary gland tissue is an extra major salivary gland in front of the parotid gland.
The primary tumor does not have readily discernible signs or symptoms as they grow within the tonsillar capsule. It is difficult to notice anything suspicious on examination of the tonsil other than slight enlargement or the development of firmness around the area. The carcinoma may occur in one or more sites deep within the tonsillar crypts.
