: Although surveillance ultrasound and alpha fetoprotein (AFP) have minimal direct harm, downstream harms from follow-up tests must be weighed against surveillance benefits when determining the value of hepatocellular carcinoma (HCC) screening programs. Our study's aims were to characterize prevalence and correlates of surveillance benefits and harms in cirrhosis patients undergoing HCC surveillance. We conducted a retrospective cohort study among patients with cirrhosis followed at a safety-net health system between July 2010 and July 2013...

Background. Fine-needle aspiration cytology (FNAC) is diagnostic standard for thyroid nodules. However, the influence of size on FNAC accuracy remains unclear especially in too small or too large thyroid nodules. The objective of this retrospective cohort study was to investigate the effect of nodule size on FNAC accuracy. Methods. All consecutive patients who underwent thyroidectomy for nodules in 2010 were enrolled. FNAC results (according to the Bethesda system) were compared to pathological diagnosis. The nodules were categorized into groups A-E on the basis of maximal diameter on ultrasound (≤0...

BACKGROUND AND AIMS: Malignant vascular invasion usually results from gross direct infiltration from a primary tumor, and impacts cancer staging, prognosis, and therapy. However, patients may also develop a remote malignant thrombi (RMT), defined as a malignant intravascular thrombus located remote and noncontiguous to the primary tumor. Our aim was to compare the endoscopic ultrasound (EUS) and the computed tomography (CT) and magnetic resonance imaging (MRI) findings of RMT and impact on cancer staging and resectability...

Video-assisted mediastinoscopy (VAM) is the most commonly used invasive method for the preoperative mediastinal staging of lung cancer and for the diagnosis of other mediastinal diseases. However, VAM has the risk of causing life-threatening bleeding consequent to the specific mediastinal anatomy. We adopted the ultrasonic technique for VAM biopsies that can easily distinguish the lymph nodes from the surrounding great vessels and thus makes the procedure easier and safer.

Sarcoidosis is a multisystem disease characterized by the presence of noncaseating granulomas, the exact etiology of which is yet to be determined. Pulmonary involvement occurs in the majority of patients and its severity ranges from asymptomatic involvement of mediastinal lymph nodes to progressive pulmonary fibrosis and chronic respiratory failure that is insensitive to treatment. Diagnosis of pulmonary sarcoidosis requires a compatible clinical picture supported by radiologic and pathologic data. A recent development in establishing the diagnosis of pulmonary sarcoidosis is endobronchial ultrasound that increases the yield of transbronchial needle aspiration of hilar and/or mediastinal lymph nodes...

We present the case of an 83-year-old man who had painful swelling of right knee for 6 months. Radiographs showed a large intra-articular soft-tissue mass with small calcifications, whereas MRI detected a multilobulated intra-articular tumor with bone erosions at the distal femur. Histopathology of ultrasound-guided biopsy specimen of the synovial mass revealed it to be a poorly differentiated metastatic carcinoma. Abdominal computed tomography with intravenous contrast medium administration found a heterogeneously enhancing large right renal mass with calcifications, which was shown to be a renal cell carcinoma on histopathology...

Metastatic tumors are rare in the breast. Well-differentiated neuroendocrine tumors (WDNETs) are slow-growing neoplasms that arise from neuroendocrine cells, particularly in the gastrointestinal tract and bronchial tree. Metastatic WDNET to the breast is a rare entity. We present a case report of ileal WDNET metastatic to the breast which was initially identified as a small mass in the patient's left breast on screening mammography. Targeted ultrasound identified a suspicious mass, and ultrasound-guided percutaneous core biopsy was performed...

INTRODUCTION: The increasing use of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) cytology to examine pancreatic neoplasms has led to an increase in the diagnosis of metastases to the pancreas. Renal cell carcinoma (RCC) is the most common metastasis to the pancreas. Our study examines 33 cases of metastatic RCC to the pancreas sampled by EUS-FNA from four large tertiary care hospitals. MATERIALS AND METHODS: We searched the cytopathology database for RCC metastatic to the pancreas diagnosed by EUS-FNA from January 2005 to January 2015...

Parathyroid cysts (PCs) account for less than 1% of all parathyroid lesions and are most commonly located along thyroid lobes, rarely at ectopic sites. PCs are important because they can pose a differential diagnostic challenge against other cystic formations of the neck. PCs can be functional (elevated serum parathyroid hormone level) and nonfunctional. Four cases of nonfunctional PCs are presented. All four female patients underwent physical examination and ultrasonography of the neck with ultrasound-guided fine-needle aspiration biopsy (UG-FNA)...

Prostate cancer is the first cancer and the second cause of cancer death in men in France. It is now a major public health issue, particularly given the increase of life expectancy. If screening is based on blood PSA and clinical examination (DRE), diagnosis requires the histological analysis of prostate samples. In current clinical routine, these biopsies are performed by endorectal through ultrasound guidance. In most cases, the cancer is not visible in the ultrasound image and the latter is used to make a dozen samples (or core), distributed as best as possible in the prostate...

Gastroesophageal junction adenocarcinoma on esophagogastroduodenoscopy biopsy. Initial PET-CT showed no definite evidence of distant metastatic disease. One month after radiation treatment, repeat PET-CT showed interval decrease in size of gastroesophageal mass but new multifocal FDG avidity in the caudate and left hepatic lobes. Correlation with contrast-enhanced CT and US images was negative, making metastasis less likely. Ultrasound-guided biopsy confirmed radiation-induced hepatitis, which caused false positively increased FDG uptake from inflammatory changes...
