[Development of intracerebral hydatid cyst evaluated with x-ray computed tomography. A case report].

In a study of a double cerebral hydatic cyst developed in a patient operated for another intracranial neurosurgical affection, the authors have determined the rate of growth of these cysts by repeated C.T. scan examinations. This rate was 4.5 cm a year, a value which is higher than other values classically accepted.
