 brain showed calcified lesion in the occipital region, reported as calcified meningioma. Magnetic resonance imaging (MRI) showed a focal lesion in the left occipital region which was hypo intense on T1W and T2W images. A right parieto-occipital craniotomy was performed revealing a cystic mass which membrane was fibrous and the contents were semi solid. The cyst was excised completely with gentle dissection. There were no postoperative deficits. Histology revealed multiple calcific deposits, and remnants of hydatid cyst. Conclusion. Calcified intracranial hydatid cysts can mimic a primary brain tumor so they should be suspected if patients live in or come from areas with endemic hydatid cyst disease. The pathological examination confirms the diagnosis when it was not considered.&picture=http://www.aascit.org/aascit/decorators/img/journal/906.jpg)

Background. Cerebral hydatid cysts are rare and less than 5% of them show calcifications. Since symptoms are similar to those of brain tumor, and can mimic these lesions on radiologic investigations, intracranial calcified hydatid cysts can be misdiagnosed. Case Presentation. A 39-year-old man presented to us with seizures. On examination, he had right-sided homonymous hemianopia. Computed tomography (CT) brain showed calcified lesion in the occipital region, reported as calcified meningioma. Magnetic resonance imaging (MRI) showed a focal lesion in the left occipital region which was hypo intense on T1W and T2W images. A right parieto-occipital craniotomy was performed revealing a cystic mass which membrane was fibrous and the contents were semi solid. The cyst was excised completely with gentle dissection. There were no postoperative deficits. Histology revealed multiple calcific deposits, and remnants of hydatid cyst. Conclusion. Calcified intracranial hydatid cysts can mimic a primary brain tumor so they should be suspected if patients live in or come from areas with endemic hydatid cyst disease. The pathological examination confirms the diagnosis when it was not considered.
