To demonstrate the existence of two imaging patterns of cerebral hydatidosis and discuss its clinical importance.
A retrospective review of six cases of cerebral hydatidosis using various imaging techniques including CT, MRI, angiography and cystogram.
Clinically the most common findings included papilloedema, headache and vomiting. Two of the cases reported recurrence of symptoms and were reoperated. The first 4 cases presented the classical signs of unilocular well defined cysts while the last two cases had multilocular, often polygonal cysts with perifocal edema, calcification and membrane detachment.
Two radiologically and pathologically distinct subtypes of hydatidosis exist. Division into groups may assist decision over treatment protocol.
