Empty sella in MR imaging. The empty sella sign is a radiological finding characterized by the partial or complete filling of the sella turcica with cerebrospinal fluid (CSF), causing the pituitary gland to appear flattened or compressed against the walls of the sella. [1] This results in the sella appearing "empty" on imaging, despite the ...
Empty sella syndrome is the condition when the pituitary gland shrinks or becomes flattened, filling the sella turcica with cerebrospinal fluid instead of the normal pituitary. [2] It can be discovered as part of the diagnostic workup of pituitary disorders, or as an incidental finding when imaging the brain.
Sheehan's syndrome, also known as postpartum pituitary gland necrosis, occurs when the pituitary gland is damaged due to significant blood loss and hypovolemic shock (ischemic necrosis) or stroke, originally described during or after childbirth leading to decreased functioning of the pituitary gland (hypopituitarism). [1]
Arnold–Chiari malformation is a condition where the cerebellar tonsils have descended, and should be considered in differential diagnosis of sCSFLS. Several complications can occur as a result of sCSFLS including decreased cranial pressure, brain herniation, infection, blood pressure problems, transient paralysis, and coma.
For the diagnosis, brain scans (such as MRI) should be done to rule out other potential causes. Specialty: Neurology: Symptoms: Headache, vision problems, ringing in the ears with the heartbeat [1] [2] Complications: Vision loss [2] Usual onset: 20–50 years old [2] Risk factors: Hypervitaminosis A, obesity, tetracyclines [1] [2] Diagnostic method
Cerebrospinal fluid (CSF) is a clear, colorless body fluid found within the tissue that surrounds the brain and spinal cord of all vertebrates.. CSF is produced by specialized ependymal cells in the choroid plexus of the ventricles of the brain, and absorbed in the arachnoid granulations.
After an apoplexy, the pressure inside the sella turcica rises, and surrounding structures such as the optic nerve and the contents of the cavernous sinus are compressed. The raised pressure further impairs the blood supply to the pituitary hormone-producing tissue, leading to tissue death due to insufficient blood supply. [2]
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e ...
