Covid-19 test caused brain fluid leak in US patient with rare condition: study

A Covid-19 nasal swab test punctured a US woman’s brain lining, causing fluid to leak from her nose and putting her at risk of life-threatening infection, doctors reported in a medical journal Thursday.

The patient, who is in her 40s, had an undiagnosed rare condition and the test she received may have been carried out improperly, a sequence of improbable events that means the risk from nasal tests remains very low.

But her case showed health care professionals should take care to follow testing protocols closely, Jarrett Walsh, senior author of the paper that appeared in JAMA Otolaryngology–Head & Neck Surgery, told AFP.

People who’ve had extensive sinus or skull base surgery should consider requesting oral testing if available, he added.

“It underscores the necessity of adequate training of those performing the test and the need for vigilance after the test has been performed,” added ear, nose and throat specialist

Report documents ‘very rare’ brain fluid leak linked to COVID-19 screening

Oct. 1 (UPI) — Researchers on Thursday described a “very rare” health complication linked with COVID-19 testing: brain fluid leak.

They documented what may be the first case — in a woman in her 40s — in a letter published by JAMA Otolaryngology-Head & Neck Surgery.

Those who have had sinus or skull-base surgery and those with known deformities of the skull base may be at risk for cerebrospinal fluid leak and should notify test takers of their history before getting screened for COVID-19, the researchers said.

“The good news is that this is a very rare event,” report co-author Dr. Jarrett E. Walsh, an ear, nose and throat specialist with the University of Iowa Hospitals and Clinics, told UPI.

“From a patient standpoint, there may be some discomfort with nasal swabs, but you should not have symptoms of persistent clear nasal drainage or significant bleeding after a swab,” particularly
