Review Case Reports
[Primary intradural extramedullary hydatidosis. Case report and review of the literature].
The authors report a case of cauda equina compression by intradural hydatid cyst. An 18-year-old man presented with paraparesis and sphincter dysfunction. MRI showed an intradural cystic lesion extending from L1 to L2 with low signal intensity on T1 and high signal intensity on T2. ⋯ All spinal areas were involved, with a predilection for the thoracic region. Neurological complications were usual with rapid spinal cord compression in this rare form of hydatid disease. The treatment was by surgery with a favourable outcome compared to the classic hydatid cyst of the spine.

Paradoxical embolism (PE) is an uncommonly diagnosed cause of unexplained ischemic cerebral event. Its diagnosis is based on established criteria and the failure to identify an arterial or cardiac embolic source. ⋯ Transesophageal contrast echocardiography is the best diagnostic test. Surgical or endovascular PFO closure is recommended for the long-term prevention of PE.
