Case Reports
[Endovascular treatment of a cervical vertebral artery pseudoaneurysm using covered stents. One case report].
Covered stents have been successfully used in the treatment of fusiform aneurysms and post dissection aneurysms in peripheral arteries as well as in post-traumatic arteriovenous fistulas. We report a case where a pseudoaneurysm of the cervical vertebral artery was excluded by placement of two covered stents, preserving patency of the parent artery, in a 15-year-old patient.

Cerebral vein and dural sinus thromboses (CVT) appear to be rare, but their identification has increased in recent year, due to the increased use of MRI and to a better knowledge of the variable clinical presentation of CVT. CVT can be diagnosed by MR and MR-angiography. Catheter angiography is reserved for cases whose diagnosis remains uncertain with MR. ⋯ In recent CVT series death rate is below 10% and about 80% of patients make a complete recovery. The treatment of CVT includes etiological and symptomatic treatment, antithrombotic therapy (anticoagulants, local thrombolysis) and the treatment of intracranial hypertension. There are few randomized trials upon which to base treatment recommendations.

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.
