Corpora amylacea in cerebrospinal fluid. A source of possible diagnostic error.

Corpora amylacea in the central and peripheral nervous system are round, amorphous intracellular bodies which are frequently found in large numbers around the ventricles of elderly individuals. These bodies were recently identified in a cytologic preparation of ventricular fluid. Although they have no known diagnostic significance, their possible confusion with yeast forms makes recognition of these structures important.
