Endovascular brachytherapy for the treatment of renal artery in-stent restenosis using a β-emitting source: A report of five patients

We report five cases of renal artery in-stent restenosis treated with endovascular brachytherapy. This procedure has been previously used extensively for the treatment of coronary artery in-stent restenosis with successful results. Therefore, it follows logically that noncoronary in-stent restenoses would also be successfully treated in this manner. Though our experience is limited, we feel that this report provides adequate data to justify the formation of a prospective trial for a more adequate evaluation of the potential utility of this intriguing approach.

Atypical presentation and progression of glioblastoma multiforme in a 6-year-old girl: multidisciplinary case report.

Glioblastoma multiforme is the most common adult malignant brain tumor but is notably less common in children. The authors describe the case of a child who presented for evaluation and treatment of neurologic signs caused by a brain stem glioma. Response to radiotherapy and chemotherapy with temozolomide was initially positive, but later extensive leptomeningeal metastasis developed. Biopsy proved the lesion to be glioblastoma multiforme. During salvage irradiation to the spine and unirradiated brain, the patient complained of hip and femur pain. Subsequent radiographs demonstrated multiple bony metastases. This pattern of spread is uncharacteristic and emphasizes the importance of adequate metastatic evaluation.
