Spinal hydatid cyst is a serious form of hydatid disease affecting fewer than 1% of all patients with hydatid disease. We report 3 healthy patients who presented with progressive paraparesis attributed to a histologically proven intradural hydatid cyst. ⋯ This localization is rare and serious, but its prognosis is excellent if diagnosis is made early enough and surgery is performed in time to prevent cyst rupture.

Comparative Study
Comparison of experimental rat models of early brain injury after subarachnoid hemorrhage.
To investigate acute pathophysiological changes after subarachnoid hemorrhage (SAH) in rats and compare endovascular perforation and double blood injection models for studies of early brain injury after SAH. ⋯ The perforation model produced more severe pathophysiological changes than the double blood injection, and it mimics human SAH in having an injured blood vessel and direct hemorrhagic brain lesion under arterial blood pressure. Therefore, endovascular perforation seems more suitable for study of acute SAH sequelae. However, further model refinement is required to reduce the high mortality rate.
