The elevated ICP may cause compression of the brain, leading to brain damage and other complications. A complication often overlooked is the possibility of hearing loss due to ICP. The mechanism of ICP on hearing loss is presumed that the transmission of CSF pressure to and from the Perilymphatic space through a patent cochlear aqueduct.
CT scans of the head increase the risk of brain cancer, especially for children. As of 2018, it appeared that there was a risk of one excess cancer per 3,000–10,000 head CT exams in children under the age of 10. [11]
The Ellsworth Howard test (a 10-20 fold increase of urinary cyclic AMP excretion following stimulation with 200 micromoles of parathyroid hormone) may be worth doing also. [citation needed] Serology for toxoplasmosis is also indicated. Brain CT scan is the preferred method of localizing and assessing the extent of cerebral calcifications.
The sign may be evident on neuroimaging such as CT scanning. [1] The sign is considered ominous because it is commonly associated with a distortion of the brain stem that can cause serious dysfunction evidenced by abnormal posturing and failure of the pupils to constrict in response to light. [1]
Cisternography is a medical imaging technique to examine the flow of cerebrospinal fluid (CSF) in the brain, and spinal cord. [1] [2] The gold standard for diagnosis of a cranial cerebrospinal fluid leak is CT cisternography. [2] For the diagnosis of a spinal CSF leak radionuclide cisternography also known as radioisotope cisternography is used ...
Neuroferritinopathy is a genetic neurodegenerative disorder characterized by the accumulation of iron in the basal ganglia, cerebellum, and motor cortex of the human brain. . Symptoms, which are extrapyramidal in nature, progress slowly and generally do not become apparent until adulthood
Focal cortical dysplasia (FCD) is a congenital abnormality of brain development where the neurons in an area of the brain failed to migrate in the proper formation in utero. [1] Focal means that it is limited to a focal zone in any lobe . [ 2 ]
The major differential to consider in empty sella syndrome is intracranial hypertension, of both unknown and secondary causes, and an epidermoid cyst, which can mimic cerebrospinal fluid due to its low density on CT scans, although MRI can usually distinguish the latter diagnosis. [10]
