A subarachnoid ependymal cyst of the spinal cord is rarely reported. A 44 year old man with a cyst compressing the lower spinal cord and conus medullaris is described. Excellent functional recovery followed excision of the lesion. The cells lining the cyst were histologically indistinguishable from normal ependymal cells, but, unlike the normal ependymal cells which are related to subependymal ...

Toxoplasma gondii infects up to one third of the world's population. A key to the success of T. gondii as a parasite is its ability to persist for the life of its host as bradyzoites within tissue cysts. The glycosylated cyst wall is the key structural feature that facilitates persistence and oral transmission of this parasite. Because most of the antibodies and reagents that recognize the cyst...
