Review Case Reports[Congenital anomaly of the inferior vena cava with hemiazygos continuation. Ultrasonic diagnosis].
Congenital anomaly of the inferior vena cava with hemiazygos continuation: ultrasonic diagnosis. We report a case of agenesis of the retro-hepatic segment of the inferior vena cava in an asymptomatic 18 year old woman, found on a routine chest-ray. This rare illness was suspected on the findings of conventional radiology and was assessed by ultrasonography that shows direct termination of hepatic veins in the right auricle, and the hemi-azygos vein behind the aorta. ⋯ In the absence of any clinical signs, CT-scan and MR Imaging were note used in investigations. Nevertheless their usefulness has been extensively reported by many authors. Cavography remains useful before surgery.

The recent advances in imaging of the temporomandibular joint (TMJ), especially the introduction of MR imaging and surface colls allowing precise visualization of superficial structures led us to reconsider the different techniques used in this very complex anatomical region, due to both its morphology and function. We also tried to determine their respective role, especially in the study of TMJ dysfunction syndromes, that represent the most frequent pathology of this region. Conventional radiography allows us to appreciate the overall amplitude of the joint movements, and to study bone abnormalities, but CT is much more precise in the study of cortical bone. In TMJ dysfunction, the joint itself is studied by either arthrography or MRI, but both techniques have their limitations and remain complementary in some aspects, which are detailed here, so that the choice between them depends on availability and therapeutic indications.

Case Reports[Celiac neurolysis. Anterior approach and x-ray computed tomographic guidance: a simple and logical technic].
Two cases of celiac plexus neurolysis under CT guidance by an anterior approach are reported. This technique was performed on two patients who complained of epigastric pain due to a pancreatic carcinoma. Alcoholization was performed with 50 cc of a 50% solution of ethyl alcohol. ⋯ In the two cases the block was successful, leading to suspension of morphine administration. Computed tomography scans after injection showed that the space of diffusion corresponds to the presumed location of the celiac plexus and confirms that the anterior approach is valid providing that a sufficient dose is injected. This technique, can be easily performed and deserves a more important place in the management of pancreatic pain.

Intravenous digital subtraction angiography. A criteria of brain death.
The absence of cerebral blood flow is the best criteria of cerebral death. Intravenous digital subtraction angiography (DSA) was performed in 110 patients with clinical signs of brain death. ⋯ Organs transplantations were performed in 30 cases. DAS represents a relatively non invasive and quick to perform method to demonstrate brain death.
