Obstruction of ventriculoperitoneal shunt by air bubble: A case report.

Complications related to Ventriculoperitoneal shunt placement are common, and multiple. Among them blockage and infection. We report a case of 44 years old man admitted to our hospital after an obstruction of his ventriculo-peritoneal shunt by an air bubble that caused behavioral problems and confusion.

[Dual energy X-ray absorptiometry as a guide for treatment of a staghorn kidney stone].

We report the history of a patient who presented a radiodense large staghorn kidney stone which was investigated by dual energy CT. Dual energy CT showed that this stone consisted of uric and calcic compounds. The patient received a specific treatment combining chemical lysis and lithotripsy active on uric and calcic parts respectively, leading to a complete noninvasive destruction of the stone.

Dual source CT: cardio-pulmonary applications.

Dual source CT is a last generation scanner which allows for coronary imaging without beta-blocker because high quality images are feasible even at high heart rates. Furthermore, with this equipment, dual energy becomes possible in a single acquisition and triple rule-out imaging can be performed in clinical routine. The radiation dose remains limited in comparison with single-source CT because of different efficient mechanisms.

[Cardiac anatomy and the radiologist].

We report a case of myocardial infarction due to occlusion of the left anterior descending artery seen on a routine chest CT performed in order to exclude aortic dissection. This underscores the need for the radiologist to look at the heart and coronary arteries on each thoracic CT-scan, even if acquired without EKG-gating.

Coronary arteries: assessment of image quality and optimal reconstruction window in retrospective ECG-gated multislice CT at 375-ms gantry rotation time.

Our objective was to evaluate the image quality of a 16-slice CT system with a rotation time of 375 ms in the assessment of coronary arteries. One hundred patients underwent iodine-enhanced CT coronary angiography within a single breath hold. Images were reconstructed in diastole, 300, 350, 400, 450, 500 and 550 ms prior to the onset of the next R-wave using absolute reverse retrospective ECG gating.

MRI of hyperacute stroke in the AChA territory.

The purpose of our study was to derive from the anatomical literature an easy-to-use map of the brain areas supplied by the anterior choroidal artery (AChA) and to assess the correspondence between damage within the putative AChA areas and clinical symptoms. A thorough review of the literature led to the recognition of 16 anatomical areas which could be delineated on routine diffusion-weighted MR images. A database of 138 consecutive ischemic stroke patients examined with MRI less than 6 h after symptoms onset was thereafter processed in a retrospective way.

Using dual-detector helical CT angiography to detect deep venous thrombosis in patients with suspicion of pulmonary embolism: diagnostic value and additional findings.

Objective: The purpose of this study was to assess the value of dual-slice helical CT angiography in detecting deep venous thrombosis in patients in whom acute pulmonary embolism was suspected and to describe the additional extrathoracic findings.

Subjects And Methods: Sixty-five consecutive patients were examined for suspected pulmonary embolism using helical CT of the chest (2.7-mm collimation; table speed, 7.

Arthritis and hidradenitis suppurativa diagnosed in a 48-year-old man.

We report the case of a 48-year-old man who presented with an erosive, seronegative, HLA-B27-negative, peripheral polyarthritis, associated with hidradenitis suppurativa of axillae and buttocks. The pertinent literature is reviewed. This paper is the second devoted to this topic in a radiological journal and the first to document erosion of the posterior aspect of the calcaneus.

Camurati-Engelmann disease: a late and sporadic case with metaphyseal involvement.

A 40-year-old white man with a 3-year history of mild to severe right thigh and knee pain was referred for radiographic investigation. Radiographs show a fusiform, bilaterally symmetrical enlargement of the diaphyses and metaphyses of the long bones (femur, tibia, fibula, radius and ulna). A narrowed medullary cavity is illustrated on CT scan of the femur.
