[In and out-of-hospital cardiac arrest and echography: a review].

Cardiac arrest is a frequent emergency for doctors and resuscitation teams. Patients displaying asystole or pulseless electrical activity are non-shockable. They have extremely poor outcomes.

Ventricular fibrillation diagnosed with trans-thoracic echocardiography.

Electrocardiographic artifacts on scope are frequently observed in pre-hospital settings. They can lead to misdiagnosis or inappropriate resuscitation treatments. Here we report a case of ventricular fibrillation by electrical injury masked by ECG artifacts, after the savage of a victim, due to persistent 50Hz domestic current and identified by trans-thoracic ultrasonography.

[Spinal fractures in ankylosing spondylarthritis. Apropos of 4 cases].

Fractures of the spine in patients with ankylosing spondylitis may be the result of minor trauma. They may lead to severe neurological deficits. They are difficult to detect on plain radiographs and CT or MRI often are required for diagnosis.

[Clinical, electrophysiological and MRI correlations in carpal tunnel syndrome].

Unlabelled: Even though diagnosis of carpal tunnel syndrome is mainly based on clinical findings, other examinations are often useful for confirmation and management. The most useful of these examinations is EMG. However, EMG may be inconclusive and MRI may then be helpful.

[Intrathyroid parathyroid adenoma].

Parathyroid adenomas are embedded within thyroid tissue in about 2-5% of cases. Intrathyroid parathyroid adenomas are easily detected at US. As such, US should be performed prior to surgical intervention.

Idiopathic carpal tunnel syndrome. Clinical, electrodiagnostic, and magnetic resonance imaging correlations.

Background: Although carpal tunnel syndrome is diagnosed primarily on clinical grounds, a number of investigations can be helpful in confirming the diagnosis and providing therapeutic orientation. Electrodiagnostic testing is the most widely used method in everyday practice but can be inconclusive or inconsistent with the clinical findings. Magnetic resonance imaging is useful in such cases.

[Congenital aneurysm of the trunk of the pulmonary artery].

A case of congenital aneurysm of the main pulmonary artery incidentally discovered following blunt chest trauma is reported. This anormaly is rare and the authors will emphasize the plain radiographic and MRI findings. The etiology and evolution of this entity are not well known.

[Retroperitoneal lymphocele: a rarely reported complication of abdominal aortic surgery. Apropos of a case].

The authors present a case of a retroperitoneal lymphocele following prosthetic reconstruction of the abdominal aorta followed by a discussion about the principal differential diagnosis of a retroperitoneal collection following surgery on abdominal aorta. To date, only ten cases have been reported in this post-operative; it is probably a more frequent complication; the radiologist must play a major role both in the detection and the treatment of such collections.
