Eggs shed in the feces of infected persons are important for the
diagnosis of coenurosis because diagnosis can only be made by the surgical
recovery of a coenurus.
A specific diagnosis must be made on the geographic distribution, organ
involvement, and number of hooklets, as not to confuse the
disease with cysticercus, a similar disease caused by another Taeniid
species. T. multiceps have larger and more numerous
laminated membrane, however, tapeworm cysts in the in
the brain are often sterile meaning that they have no protoscolex in their
cavity. Under this condition, a definitive diagnosis is impossible to
make, although supportive evidence can be obtained through an examination
cerebral spinal fluid which may have an increased protein and cellular
content (pleocytosis) during times of infection.
Serologic tests are not widely used with this disease because of cross-reactivity with other cestode antigens, although it may be possible that a Casoni test (an immediate hypersensitivity skin test used to detect sensitization to hydatid antigen) would be positive in for this disease.
