Giant Multiple Skull Hydatidosis in a Child: A Case Report & Review of the Literatures

Cranial hydatidosis is a relatively rare disease, accounts for 3% of hydatid disease, most of the times, cyst(s) is (are) confined to the white matter, in the supratentorial regions, esp. the parietal lobe being the most common involved part i.e. in the vascular territory of middle cerebral artery. Overall, extraaxial hydatid cysts occur in a rare manner, esp. skull hydatidosis which is reported very scarcely, makes up 3-4% of bone hydatidosis. Method: In our case, we represent a single case of giant multiple skull hydatid cysts (> 100) occupying most of the left hemisphere and discuss its delayed pattern of presentation, radiological features emphasizing on its erosive nature, operative procedure & its nuances, outcome and some effects of rapid decompression of chronically compressed brain. The literature of both skull & epidural cerebral hydatid cyst were reviewed. Conclusion: Skull hydatids, are very rare, can be multiple, multilocular, can reach a huge size, & can cause sever bone erosions before the patient seeks medical help. Surgical therapy is the mainstay modality.
