A rare entity of primary hydatid cyst located between the two layers of the intracranial dura in a child: a case report

INTRODUCTIONHydatid disease is a parasitic infection caused by the tapeworm Echinococcus granulosus. Intracranial locations are rare and account for less than 3% of all cases. Typically, these cysts are found in the intracerebral spaces. However, this study presents an extremely rare intradural hydatid cyst. To our knowledge no similar case has been previously reported.CASE PRESENTATIONThis study presents the case of an 8-year-old boy presented with a 3-month history of headache and vomiting without any neurological deficit. Full radiological investigations were performed, the brain MRI showed a large cerebral hydatid cyst located within the dura layers between the periosteal and the endosteal layers. Surgery was performed without cyst rupture, confirming the intracerebral intradural location.CONCLUSIONEarly diagnosis and treatment for intracranial hydatid cysts are crucial to prevent complications such as neurological deficits, seizures, and even death. In this case, the intracerebral intradural location of the cyst is extremely rare.
