RESUMO
Major breakthroughs in catheter and guidewire design as well as improvements in angiographic x-ray equipment currently allow interventional radiologists to diagnose massive life-threatening upper and lower GI hemorrhage and to stop the bleeding safely and effectively using superselective catheterization and microcoil embolization. For chronic or recurrent GI bleeding, when endoscopy is unrevealing or equivocal, barium studies, CT scanning, nuclear medicine studies, and angiography can help determine the cause of bleeding. A multidisciplinary approach, including the gastroenterologist, radiologist, and surgeon, is extremely helpful in managing GI bleeding, particularly in high-risk patients or patients presenting as diagnostic dilemmas.

Malignant tumors that arise in the perinephric space often present a diagnostic dilemma. These retroperitoneal tumors may resemble renal carcinomas, extrahepatic lymphoma, metastatic disease, or tumors arising in other retroperitoneal organs. We present a case of a patient with a primary retroperitoneal rhabdomyosarcoma who had an extensive diagnostic workup prior to surgical intervention that was thought to be consistent with an aggressive renal cell carcinoma.

A case of articular sporotrichosis occurring in the wrist and ankle of a 39-year-old man is reported. Review of the literature on this disorder confirms the diagnostic difficulties presented by this usually chronic, progressive, fungal arthritis. The diagnosis of this entity should be considered in the evaluation of any patient presenting with a progressive destructive arthritic process. The pathological and radiological features of a typical case are discussed and the mechanisms of infection and type of individual affected by this disease are described.

The frequent use of heavy eyeglasses by the angiographer has resulted in significant discomfort due to "sliding glasses." Described is the optical push device, which allows the angiographer to adjust eyeglasses comfortably while maintaining sterility.

Four patients exhibited thoracic venous collateral circulation on CT of the chest. No clinical or CT evidence of venous obstruction was seen. Repeat CT in one patient following repositioning of the arms from hyperabducted to the anatomic position showed absence of collateral circulation. It appears that hyperabduction of the arms during performance of chest CT can occasionally cause transient obstruction of the subclavian vein and opacification of collateral venous channels.
