Can a virus cause or impact an underlying pulsatile tinnitus cause? This report indicates that in some cases it can.
The report describes a case that the doctors indicate had not previously
been described. A 24-year-old man who had suffered viral meningitis just four months before the PT started was admitted
to the hospital for symptoms or viral meningitis and was diagnosed with a cavernous sinus DAVF.
The writers suggest,
"The viral meningitis most likely caused the inflammation that may be responsible for the occurrence of the cavernous
sinus DAVF. Prompt treatment for inflammation may help to prevent the development of DAVFs."
