Primary Cerebral Hydatid Cyst: Two Cases Report
Objective: Cerebral hydatid disease (CHD) is a rare manifestation of
echinococcosis but it constitutes a significant fraction of all
intracranial mass lesions. In this paper we have reported two children
with primary CHD without associated extracranial lesions. Case
Presentation:Two cases of isolated cerebral hydatid disease are
described. They were 7- and 10-year old children referred with focal
neurological deficits and intracranial hypertension. Extensive
extracranial investigations were negative. The literature concerning
isolated cerebral hydatid disease is reviewed, and possible mechanisms
by which the disease can be limited to brain, are discussed.
Conclusion: Isolated CHD can occur with different mechanisms. Lack of
effective immune system in the brain, the special architecture of brain
tissue permitting rapid growth of cyst, patent ductus arteriosus, and
patent foramen ovale, have been the proposed factors, but none of them
has been proved yet
