With the increased use of advanced imaging techniques, incidental renal mass have become a very frequent finding (1). Approximately 13 to 27% of abdominal imaging studies incidentally identify a renal lesion , a fact that makes suspected renal cell carcinoma be diagnosed at an early stage (2). Most excised small renal cancers are classified as low grade at… (More)
The concept of a hybrid operating room represents the union of a high-complexity surgical apparatus with state-of-the-art radiological tools (ultrasound, CT, fluoroscopy, or magnetic resonance imaging), in order to perform highly effective, minimally invasive procedures. Although the use of a hybrid operating room is well established in specialties such as… (More)

OBJECTIVES To evaluate the efficacy of microbubble contrast ultrasound in diagnosis of hepatocellular carcinoma and to compare its results with those of magnetic resonance and histopathology. METHODS A total of 29 patients suffering from chronic liver diseases and awaiting liver transplants at Hospital Israelita Albert Einstein were subject to magnetic… (More)
Hepatocellular adenoma is a rare benign tumor that was increasingly diagnosed in the 1980s and 1990s. This increase has been attributed to the widespread use of oral hormonal contraceptives and the broader availability and advances of radiological tests. We report two cases of patients with large hepatic adenomas who were subjected to minimally invasive… (More)
