👉 The Carney-Fisher syndrome fluid, also known as Carney-Fisher fluid, is a rare and distinctive cerebrospinal fluid (CSF) characterized by its high protein content and specific immunological properties. Unlike normal CSF, which typically contains less than 100 mg/L of protein, Carney-Fisher fluid can have protein concentrations exceeding 1,000 mg/L. This elevated protein level is often accompanied by the presence of autoantibodies, particularly anti-Ro/SSA and anti-La/SSB antibodies, which are indicative of the syndrome's autoimmune nature. The fluid's unique composition and immunological profile help distinguish it from other types of CSF abnormalities, making it a valuable diagnostic marker for Carney-Fisher syndrome.
