Primary multiple cerebral hydatid cysts with unusual features

We present a case of 45 years old female patient with two primary cerebral hydatid cysts, each localised in separate hemispheres. Detailed studies revealed no evidence of hydatid disease elsewhere in the body. The cysts were removed by two separate operations. Though the cyst in the right posterior parietal lobe was delivered unruptured, seven months later a new cyst was detected in the same cavity, which seems to show relatively rapid growth in a year, and was also removed unruptured.
