OBJECTIVE: To determine whether knowledge about the degree of radiopacity of the double-J ureteral catheters utilized in Spanish hospitals suffices for correct radiologic control and subsequent follow-up. METHODS: The CT attenuation index was utilized to determine the degree of radiopacity of 23 double-J ureteral stents, comprised of different biomaterials and from different manufacturers, that are used in Spanish hospitals. RESULTS: The values ranged from 1,000-3,070 Hounsfield units. CONCLUSION: All the catheters analyzed were sufficiently radiopaque to permit good radiologic control during insertion and subsequent follow-up. The radiopacity of the stent depends on the metal salt employed during the manufacturing process and not on the biomaterial.

We present the case of a 59 years old male with Wegener's Granulomatosis with uncommon manifestations such as diffuse pulmonary hemorrhage and acute renal failure due to necrotizing glomerulonephritis. Neutrophil anticytoplasmic antibodies determination was negative. Conventional and high resolution thoracic computed tomography showed cavitated lung nodules with small peripheral vessels. These lesions, that are characteristic of this type of vasculitis, were not appreciated on the routine chest roetgenogram. Definitive diagnosis was made by the histological study of open lung and renal biopsies. Favourable response to corticosteroids, immunosuppressive drugs and hemodialysis was obtained. Diffuse pulmonary hemorrhage is an uncommon manifestation of Wegener's Granulomatosis, and must be considered as a vital emergency that justify the use of aggressive diagnostic and therapeutic methods.

The sensitivity, specificity and predictive values of dynamic CAT with contrast piston-stroke performed at a single cut are described for the diagnosis of hepatic hemangiomas. We analyzed the correlation between the findings obtained through dynamic CAT and those obtained through echography, PAAF, analytic and clinical study of the patients with suspicion of hepatic hemangioma. The following values were obtained: sensitivity 92.3%; specificity 50%; VPP 88.8%; VPN 60%; and global diagnostic affectivity 84.37%. According to these results, we think that dynamic CAT is a highly reliable test for the diagnosis of hepatic hemangiomas.

Occlusion of the top of the basilar artery causes infarctions in supra- and infra-tentorial regions (thalamus, occipito-temporal lobes, rostral trunk and cerebellum) with characteristic clinical and radiological manifestations. We studied 17 patients with this syndrome whose clinical data and neurological images led us to classify them into four groups: type I (2 patients, 12%), showing mainly alterations in consciousness and ocular motricity, and bilateral thalamic infarction; type II (6 patients, 35%), with campimetric manifestations and uni- or bilateral ischemia of the occipito-temporal lobes; type III (5 patients, 29%), with associated corticospinal deficits and lacunar images in the rostral brainstem; and type IV (4 patients, 24%) with symptoms of and neuro-images revealing lesions in the cerebellum. The proposed classification is an attempt to facilitate diagnosis by neuro-imaging and to group patients according to prognosis.

Three cases of cysts arising from the second branchial cleft are described. They were completely removed. Histopathological examination revealed that cysts were lined with columnar (respiratory type) epithelium. The authors take this opportunity to review the underlying pathogenic mechanism, the clinical manifestations and therapeutic procedures.

Corrected transposition of the great arteries is an unusual congenital heart defect, above all at ages over 40. Echocardiography and invasive angiography are still cornerstones for its diagnosis. However other non-invasive techniques, such radionuclide angiocardiography and computed tomography, not so used in this malformation, can help us in its detection. We present 2 cases of corrected transposition of the great arteries in adults in which these methods were used and review the literature.

A 50 year old man, affected by a Wegener's granulomatosis limited to lung, is presented. The indirect immunofluorescence test for "Anticytoplasmic Antibodies" (ACPA) was negative and we got the definitive diagnostic by the histological study from thoracotomy and biopsy samples. We started treatment with trimethoprim-sulfamethoxazole and a good evolution with an adequate clinical control, x-ray study and blood test was obtained. Some aspects of the value of the ACPA as diagnostic and activity markers of the disease and also the use of an antimicrobial agent on the treatment of this nosological entity are discussed.
