If too much brain fluid leaks out, the brain sags inside the head, putting pressure on parts of the skull and causing headaches, a condition known as spontaneous intracranial hypotension, National Organisation for Rare Disorders states.
As a result, the unknowing health professional who administered the nasal swab to test for coronavirus had damaged this mass within her nose, causing the leakage of CSF.
This creates a gap through which cerebral spinal fluid, brain tissue and the meninges (the membrane that covers the brain) can protrude into a sac-like formation.The journal states the patient had likely had the condition for many years, but it had probably been misdiagnosed as sinus disease.
This caused cerebrospinal fluid (CSF) – which is clear fluid that protects the brain and spinal cord – to leak.
Thankfully, after doctors operated to reduce the mass, they were able to treat her undiagnosed condition with a soft skin graft and stop it protruding out of her skull.
