OBJECTIVE Our objective was to describe the radiologic findings of segmental testicular infarction and to establish a proper diagnosis that can avoid orchiectomy. CONCLUSION The presence of a triangular-shaped avascular intratesticular lesion on sonography or MRI and enhancement of the surrounding borders on enhanced MR images may suggest a presurgical(More)
We report the appearance of three cases of Leydig cell tumours on MRI. This imaging method showed well-defined and peripheral intratesticular tumours displaying marked and homogeneous enhancement when contrast medium was used. This latter finding was only observed in Leydig cell tumours when they were compared in a series of 104 patients with different(More)
OBJECTIVE The purpose of this essay is to illustrate the imaging findings of congenital cystic lesions of the biliary tract. CONCLUSION Congenital cystic lesions of the biliary tract include ductal plate malformations and choledochal cysts and can be recognized with characteristic imaging findings and basic knowledge of the embryologic development of the(More)
The appearance of solitary late metastases of renal cell carcinoma has seldom been documented. A male patient, who 5 years ago underwent left radical nefrectomy for renal cell carcinoma, presented with a solitary pancreatic metastasis (an uncommon site of metastasis for renal cell carcinoma), which was successfully treated with partial pancreatectomy. The(More)
Undescended ovary is a rare disorder that can be associated with müllerian malformations. There is an unclear association with infertility and malignant disease. When an ovary is not in its normal location, it is sought in other locations above the pelvic brim. This is important in cases of undetermined cyclical abdominal pain, follicle aspiration and(More)
A case of polymyositis and localized vasculitis presenting as a muscular pseudotumor of a lower extremity and periostitis several years after the onset of symptoms was reported and the MRI characteristics were described. This imaging modality demonstrated muscle signal abnormalities in several muscle groups and was useful in ruling out the presence of a(More)
INTRODUCTION AND OBJECTIVES To study electrical cardioversion in patients with atrial fibrillation as a potential cause of acute ischemic brain lesions. METHODS We performed prospective analysis of 62 consecutive patients (62 [10] years, 16 female). All of them were anticoagulated for at least 3 weeks with an international normalized ratio of 2.69 (0.66).(More)
An asymptomatic case of cystic renal carcinoma is presented. The only diagnosis of certainty was given by a marked increase in L.D.H. levels in the fluid of the tumor after puncture. The pros and cons of imaging studies, and the relative lack of value of aspiration cytology when negative results are encountered are discussed. The pathological anatomical(More)
Emergence of multiple bilateral renal cysts observed in patients undergoing periodic haemodialysis is 40%. The pathology, known as Acquired Cystic Renal Disease (A.C.R.D.) presents a high association to renal cancer. Two cases of A.C.R.D. and their association with hypernephroma, one resulting in secondary retroperitoneal haemorrhage and the other in(More)
