OBJECTIVE: To evaluate whether the Aorta-Lesion-Attenuation-Difference on contrast-enhanced CT can aid in the differentiation of malignant and benign oncocytic renal neoplasms. MATERIALS AND METHODS: Two independent cohorts-an initial (biopsy) dataset and a validation (surgical) dataset-with oncocytomas and chromophobe renal cell carcinomas (chRCC) were included in this IRB-approved retrospective study. A region of interest was placed on the renal mass and abdominal aorta on the same CT image slice to calculate an Aorta-Lesion-Attenuation-Difference (ALAD)...

REVIEW
Ricardo R N Leão, Ardalan E Ahmad, Patrick O Richard
Over the last few decades, the incidence of renal cell carcinomas (RCCs) has been steadily increasing. This is primarily due to an increase in detection of small renal masses (SRMs) as a result of widespread utilization of abdominal imaging. Interestingly, up to 30% of incidentally discovered SRMs (solid lesions measuring ≤4 cm) are benign, and consequently, the definitive treatment of all SRMs is associated with a considerable risk of overtreatment. To decrease the overtreatment rate, renal tumour biopsy (RTB) has been advocated as a safe alternative to identify the pretreatment histology of these SRMs...

PURPOSE: Percutaneous biopsy obtained from a single location is prone to sampling error in large heterogeneous renal masses, leading to nondiagnostic results or failure to detect poor prognostic features. We evaluated the accuracy of percutaneous biopsy for large renal masses using a modified multi-quadrant technique vs. a standard biopsy technique. MATERIALS AND METHODS: Clinical and pathological data for all patients with cT2 or greater renal masses who underwent percutaneous biopsy from 2009 to 2014 were reviewed...

BACKGROUND: Minimal change disease (MCD) and primary focal segmental glomerulosclerosis (FSGS) are glomerular diseases characterized by nephrotic syndrome. Their diagnosis requires a renal biopsy, but it is an invasive procedure with potential complications. In a small biopsy sample, where only normal glomeruli are observed, FSGS cannot be differentiated from MCD. The correct diagnosis is crucial to an effective treatment, as MCD is normally responsive to steroid therapy, whereas FSGS is usually resistant...

BACKGROUND: Late pulmonary metastasis from urothelial carcinoma (UC) of the upper urinary tract is extremely rare. CASE PRESENTATION: A 76-year-old man was referred to our hospital due to an abnormal shadow on chest X-ray. He had a history of left nephrectomy with a diagnosis of UC in the renal pelvis 29 years previously. Computed tomography showed a mass lesion in the right middle lobe of the lung that measured 4.9 cm in diameter. A transbronchial biopsy revealed the tumor to be metastatic pulmonary UC, and he underwent right middle lobectomy of the lung...

Gelsolin amyloidosis is a rare type of amyloidosis typically involving the cranial and peripheral nerves, but rarely the kidney. Here we report the clinical, kidney biopsy, and mass spectrometry findings in 12 cases of renal gelsolin amyloidosis. Of the 12 patients, five were men and seven were women with mean age at diagnosis of 63.8 years. Gelsolin amyloidosis was most common in Caucasians (six patients) and Asians (four patients), and included one each African-American and Hispanic patients. Nephrotic syndrome was the most common cause of biopsy, although most patients also had progressive loss of kidney function...

INTRODUCTION: Cryoablation (CA) is a minimally invasive modality for the management of small renal cortical neoplasms (RCN). Successful ablation is dependent on achieving target temperatures during CA that result in tumor cell death. We investigated long-term oncological outcomes following CA using Multi-Point Thermal Sensors (MTS), which allow precise temperature determination at four points along the needle. METHODS: We performed a retrospective review of 20 patients with < 4 cm RCN who underwent de novo CA from 2005 to 2009...

Well-differentiated hepatocellular carcinoma (HCC) shares overlapping histological features with benign hepatocellular lesions, including hepatocellular adenoma (HCA) and focal nodular hyperplasia (FNH) in non-cirrhotic liver, and with high-grade dysplastic nodule (HGDN) in cirrhotic liver. Several metastatic tumors, such as neuroendocrine tumor, renal cell carcinoma, adrenocortical carcinoma, melanoma, and epithelioid angiomyolipoma, can be indistinguishable from HCC on histologic grounds. Since this distinction has important therapeutic implications, judicious use of immunohistochemical markers plays an important role in establishing an accurate diagnosis, especially when limited material of tumor is available on cell block or a small core biopsy...

The differentiation of benign and indolent renal masses from aggressive tumor histologies cannot be reliably performed by CT or MRI. Additionally, renal mass biopsy risks complications and has a nondiagnostic rate of 10% to 20%. Tc-MIBI SPECT/CT has been shown to allow for the accurate differentiation of benign renal oncocytomas and hybrid oncocytic/chormophobe tumors from other more aggressive renal tumor types. We present the case of an 84-year-old man with chronic kidney disease and an 11.2-cm renal mass...
