[A diagnostic analysis of imaging in ocular cysticercosis].
OBJECTIVE
To discuss B-ultrasonography, CT and MRI appearances and image diagnostic value for ocular cysticercosis.


METHODS
In the 29 cases with ocular cysticercosis, 21 cases were examined by B-ultrasonography, 19 cases by X-ray computed tomography (CT) and 6 cases by magnetic resonance imaging (MRI).


RESULTS
At the living stage of the cysticercus, B-ultrasound might detect parasitic cyst and its movement in the eyeball and orbit, extraocular muscle irregular hyperplasia; CT might detect parasitic cyst in the orbit and the pathologic extraocular muscle; MRI might detect the parasitic cyst in the eyeball and the orbit and the pathologic extraocular muscle. At the non-living stage of the cysticercus, B-ultrasonography and CT might discover calcification focus in the eyeball and extraocular muscle.


CONCLUSIONS
Image appearances of ocular cysticercosis depend on the parasitic site and living status of cysticercus in the eye region. For diagnosis, B-ultrasonography may first be selected, MRI secondly selected for living stage and CT secondly selected for non-living stage of the ocular cysticercosis.
