Isolated third ventricular hydatid cyst at the foramina of Monro presenting with obstructive hydrocephalus: A case report

This case highlights the importance of high clinical suspicion, precise imaging interpretation, and meticulous surgical technique when managing rare CNS hydatid cysts, especially in endemic areas. To the best of our knowledge, this represents one of the very few reported cases of a third ventricular hydatid cyst worldwide. The report highlights both the extreme rarity of this localization and the importance of meticulous surgical removal and adjunct antiparasitic therapy in preventing recurrence, offering valuable insights for neurosurgeons practicing in endemic regions.
