    Notes: Abstract Background and purpose. Abnormalities of the chest wall have been described in bronchopulmonary dysplasia (BPD). Clinical, radiographic and pulmonary function variables were evaluated in 1-year-old children ventilated because of neonatal lung disease in order to quantify these thoracic changes and to evaluate the lung disease. Methods. The pulmonary status of 51 infants with neonatal lung disease requiring artificial ventilation was reevaluated clinically and radiographically at the age of 1 year. Twenty-two of these infants had developed BPD. Thoracic depth and width were measured clinically and on chest X-ray. The Toce score evaluated the presence of cardiomegaly, hyperinflation, emphysema and interstitial lung disease. Lung function was measured after sedation using previously reported methods. In BPD patients, Toce score and lung function were determined and compared at 1 month and at 1 year of age. Results. In BPD patients, chest depth was significantly smaller when measured clinically as well as on chest radiograph (P 〈 0.05; Mann-Whitney U-test). There was a statistically significant correlation between chest depth measured clinically and on chest X-ray. Toce score was significantly higher in BPD patients (P 〈 0.05). In BPD patients intersitial abnormalities and decreased lung compliance were more frequent at the age of 1 month than at the age of 1 year. At the age of 1 year, hyperinflation was more frequent and at that time increased airway resistance was still noted. Thus the type of X-ray abnormality reflects the type of lung function disturbance. Conclusion. The flatness of the chest is most likely a consequence of the long-standing lung function abnormalities.

    Notes: Abstract Two cases of dermoid cysts of the posterior fossa in association with a dermal fistula and with different clinical presentations are reported. The patient in case 1 is a 14-month-old girl with a history of recurrent bacterial meningitis. Case 2, a 7-year-old girl, presented with a skin “granuloma” at the inion. Both cases, and a review of the literature, demonstrate the need for a thorough exploration of the cranial and spinal midline skin areas in every newborn and argue for widespread use of nuclear magnetic resonance imaging whenever a suspected midline lesion is found.

    Notes: Abstract The early occurrence of peritoneal signs and hyperamylasemia in a 14-year-old boy, who had fallen off his horse, urged us to perform a sonographic and computed tomographic study of the upper abdomen. Both examinations showed a complete pancreatic rupture. Distal pancreatectomy led to a rapid and uneventful recovery.

    Notes: Abstract Obstructive jaundice is a very rare complication of peptic ulcer disease. We report a patient who presented with symptoms suggestive of malignant distal common bile duct stenosis. A final diagnosis of benign duodenal ulcer with stricture of the common bile duct was made. A short review of the literature is also presented.

    Notes: Abstract In a patient with Addison's disease, who gave a history of a severe car accident, CT showed bilateral enlargement of the adrenal glands. MRI, by demonstrating paramagnetic T1 shortening due to methaemoglobin and haesmosiderin on T2-weighted images, confirmed the haemorrhagic nature of the lesions.

    Notes: Abstract A 14-year-old boy presented with the clinical and radiological features of rickets. Serum inorganic phosphate levels were constantly low, whereas serum calcium and parathyroid hormone levels were within the normal range. Laboratory investigation did not show any evidence for vitamin-D deficiency, chronic renal insufficiency, Fanconi syndrome, tubular acidosis, hepatic disease or intestinal malabsorption. A family study comprising 34 members over four generations revealed 10 other individuals to be affected and the mode of inheritance to be autosomal dominant. In addition to hypophosphataemia and normocalcaemia, the diasease is characterized by elevated serum 1,25 dihydroxyvitamin D levels and hypercalciuria. This hereditary syndrome of renal hypophosphataemia differs from the common familial X-linked hypophosphataemia and the recently described autosomal recessive hypophosphataemic rickets with hypercalciuria by its dominant mode of inheritance; it differs from hypophosphataemic non-rachitic bone disease by the elevated serum 1,25 dihydroxyvitamin D levels and hypercalciuria.

    Description / Table of Contents: Zusammenfassung Trotz vieler Verbesserungen bleiben folgende Beschränkungen der üblichen MRA bestehen: saturierte Gefäße, die die Visualisierung der Venen und Arterien mit langsamem Fluß und spindephasischen „Löchern“ an Stellen mit turbulentem Fluß beeinträchtigen. Neuerdings wird durch Einsatz von Kontrastmitteln versucht, mit diesen Restproblemen besser zurecht zu kommen. Mittels induzierter Kürzung der T1-Dauer, wurde die Saturierung in den Blutgefäßen überwunden. Damit werden die Arterien und Venen mit derselben Signalintensität visualisiert; folglich ist die Aufnahmetechnik weniger flußabhängig. In Kombination mit dieser Neuerung kann heute eine CE-MRA durchgeführt werden, während der Patient den Atem anhält. Diese Vorgehensweise ist sehr vielversprechend bei Anwendungen im Abdominalbereich, weil sich so die respiratorische Bewegung „einfrieren“ läßt. Da mit dieser Methode auch die Echozeiten sehr kurz sind, kann die Spindephasierung reduziert werden. Die Einführung von Kontrastmitteln hat also den klinischen Nutzen der MRA erheblich vergrößert.
    Notes: Summary Despite many optimizations, the current limitations of plain MR angiography include: saturation that impairs the visualization of veins and arteries with slow flow and spin-dephasing signal voids in locations with turbulent flow. Recently, the use of contrast agents has been proposed to cope with these remaining problems. Because of induced shortening of the T1 of the blood, saturation in the blood vessels is overcome. As a result, arteries and veins are visualized with the same signal intensity, which makes the technique less flow-dependent. In combination with short T1-weighted acquisitions, today CE MRA can be obtained while the patient is holding his breath. This last approach is most promising for abdominal applications since the respiratory motion can be frozen. As these acquisitions also use very short echo times, spin dephasing can be reduced. In conclusion, the use of contrast agents has greatly increased the clinical usefulness of MR angiography.

    Notes: Abstract Purpose: To describe a combined procedure of repositioning and leaving in situ a central venous catheter followed by immediate percutaneous treatment of associated superior vena cava syndrome (SVCS). Methods: Eight patients are presented who have central venous catheter-associated SVCS (n = 6 Hickman catheters, n = 2 Port-a-cath) caused by central vein stenosis (n = 4) or concomitant thrombosis (n = 4). With the use of a vascular snare introduced via the transcubital or transjugular approach, the tip of the central venous catheter could be engaged, and repositioned after deployment of a stent in the innominate or superior vena cava. Results: In all patients it was technically feasible to reposition the central venous catheter and treat the SVCS at the same time. In one patient flipping of the Hickman catheter in its original position provoked dislocation of the released Palmaz stent, which could be positioned in the right common iliac vein. Conclusion: Repositioning of a central venous catheter just before and after stent deployment in SVCS is technically feasible and a better alternative than preprocedural removal of the vascular access.

    Notes: Abstract A 32-year-old woman presented with a pulsatile, painful mass in her left upper arm, originating several days after removal of an Ilizarov external fixation. The diagnosis of a pseudoaneurysm was made by medical history and by physical and ultrasonographic examination of the mass. Angiography confirmed the presence of the pseudoaneurysm, originating from a branch of the arteria profunda brachii, and definitive treatment was performed by transcatheter embolization. Clinical follow-up showed absence of pulsation and pain in the upper arm and a gradual volume decrease of the mass lesion.
