We report a case of a paratesticular LMS in a 60-year-old man who presented with a right scrotal mass. The patient was evaluated by scrotal ultrasound and computed tomography of the abdomen and pelvis (including scans of the scrotum), which revealed a large extratesticular mass. The lesion proved to be malignant and the patient underwent radical orchiectomy with high cord ligation. To improve the assignment of this lesion, we further analyze the imaging features of LMS and corre-late them with pathologic findings.展开更多

The site of the surgical anastomosis is most commonly involved, but sites both proximal and distal to the anastomosis may occur, as well. Angioplasty is the gold standard for the treatment of the stenosis, especially for intrarenal lesions. We report two cases of intrarenal TRAS and successful management with angioplasty without stent placement. Both patients were male, 44 and 55 years old respectively, and they presented with elevated blood pressure or serum creatinine within three months after transplantation. Subsequently, they have undergone angioplasty balloon dilatation with normalization of blood pressure and serum creatinine returning to baseline level. Percutaneous transluminal balloon renal angioplasty is a safe and effective method for the treatment of the intrarenal TRAS.展开更多
