The authors present two observations of degenerative spondylolisthesis causing canal stenosis in which the stenosis was not apparent on MRI examination, due to reduction of spondylolisthesis in the supine position. In these cases, MR images of the facet joints showed unusual large areas with hypersignal on T2 weighted images suggestive of fluid collection. Observation of such images on supine MRI images should raise the suspicion of a spondylolisthesis existing on standing examination but reduced by the supine position, possibly leading to underestimating the canal stenosis.

Ultrasonography has progressively become an easily available non expensive imaging modality for the study of the small intestine. It has no secondary effects and is comforting for the abdominal radiologist. Further, as ultrasonography does not require special preparation nor contrast administration in the intestine or vascular system, no delay is caused if other imaging modalities (such as CT or angiography) have to be performed. This report covers the most common pathologic conditions in the small bowel and does not consider enteroliths, foreign bodies nor mucoviscidosis.

Arterial embolization was performed in ten skeletal metastases occurring in nine patients: eight patients presented with renal cell carcinoma and one with bronchogenic carcinoma. Five metastatic lesions were located in the spine, one in the pelvis, three in the proximal humerus and one in the proximal femur. Selective arterial embolization was performed preoperatively in seven cases and as a palliative treatment in three cases. The embolic material used was polyvinyl alcohol particles, gelatin sponge and coils or a combination of these. Arterial embolization was technically successful in all patients achieving subtotal (> 90%) tumour devascularization in five metastases and a 75% devascularization in the remaining five lesions. In operative patients, median intra-operative volume of blood transfusion was 510 mL. Palliative embolization was followed by major pain relief in two cases and moderate relief in one case lasting from 7 to 26 months. Arterial embolization is an effective and safe adjunctive treatment of hypervascular bone metastases.
