The clinical course is usually insidious and chronic. The symptoms,
requiring several years to develop, depend upon the exact location of the
larvae or coenurus. If the coenurus enters the brain, meningeal symptoms
may include headache, transient hemiparesis, and epileptiform seizures,
increased intracranial pressure, and a loss of consciousness. The
full-blown syndrome is a space-occupying lesion. In the
coenurosis takes on either an intraocular or orbital form which occurs in
the subconjunctival space, eyelids, or extrinsic muscles. The symptoms
are blurred vision or diplopia. The rare species, T. brauni, T.
and T. glomerulus cause subcutaneous and muscle infection. When the
coenurus develops in muscle tissue a painful nodule often results.
Subcutaneous coenurosis produces a nodule similar to the one
in muscle tissue, but this one tends to be painless. These nodules are
usually to be smaller than 6 centimeters in diameter and are most commonly
located in the truck although they can also be found in the neck, head or
limbs. Systemic allergic symptoms have also been reported in a case of
coenurosis of the breast.
