RESUMO
Spinal meningiomas account for 12% of all the meningiomas and are usually located in the intradural extramedullary space. In some cases, they are associated with some extradural extensions. However, purely extradural spinal meningiomas are rare. Additionally, it is difficult to make an accurate preoperative diagnosis. We report a case of pathologically confirmed atypical meningioma, presented as a posterior epidural mass on the thoracic spine. We review the case, clinical symptoms, radiologic findings and the histologic features.
RESUMO
Renal artery injury is a rare complication in blunt trauma, but can cause devascularization of the kidney, leading to renal failure. It requires early diagnosis and management. The treatment of renal artery injury still remains controversial, but recent studies have reported the successful treatment outcome with endovascular stent placement. Nevertheless, there is no standard treatment strategy in cases of pediatric patients. We report a case of a 16-year-old girl with right renal artery occlusion associated with a grade IV liver laceration. She was treated with only balloon angioplasty, and the kidney showed marked improvement of parenchymal perfusion with normalized renal function. Treatment with only balloon angioplasty can be a treatment option in pediatric patients with renal artery injury.
