The presence of circulating tumor cells (CTC) or microemboli (CTM) in the peripheral blood can theoretically anticipate malignancy of solid lesions in a variety of organs. We aimed to preliminarily assess this capability in patients with pulmonary lesions of suspected malignant nature. We used a cell-size filtration method (ScreenCell) and cytomorphometric criteria to detect CTC/CTM in a 3 mL s...

OBJECTIVES To investigate the value of contrast-enhanced ultrasound (CEUS) in guidance of percutaneous biopsy in peripheral pulmonary lesions. METHODS This study focused on 53 patients (male: 38, female: 15, and mean age: 55.7 years ± 10.7) with 53 single peripheral pulmonary lesions. Before core needle (16-gauge) percutaneous biopsy, CEUS were performed in all lesions, with injection of 2.4 ...

Lymphomatoid granulomatosis (LG) is currently called as extranodal angiocentric and angiodestructive immunoproliferative disorder with various degrees of histological differentiation and disease severity. Histological grading and clinical manifestations are due to number of atypical large EBV + B-lymphatic cells. We report the case of a 23-year-old man clinically presented with fever, sweating,...

Computed tomography (CT) allows the performance of fine needle aspiration biopsies in situations in which ultrasound or conventional X rays do not correctly visualize the lesion or the needle tract. One hundred four patients with a clinical suspicion of neoplasia were subjected to CT guided percutaneous aspiration biopsies in a lapse of 6 years. The most frequently biopsied organs were the lung...

Background Needle guides have recently come into use for ultrasound-guided percutaneous renal biopsies; however, it is not yet clear if the use of needle guides leads to decreased post-biopsy complication rates and improved tissue yields. Thus, we conducted a retrospective single center study comparing biopsy yield, adequacy, and rates of complications before and after utilization of a needle g...

A 60-year-old male presented with dyspnea and chest pain. He was referred with massive bulky mass. A mass in the left lung was observed using chest X-ray (Figures 1).  A computed tomography scan of the chest showed a mass on the left lung with complete lung collapse Figures 2 (A, B). The needle biopsy was performed and the case was diagnosed with solitary fibro...

BACKGROUND Biopsy is a crucial step within the diagnostic cascade in patients with suspected bone or soft tissue sarcoma. Open biopsy is still considered the gold standard. However, recent literature suggests similar results for percutaneous biopsy techniques. Therefore, the aim of this retrospective analysis was to compare open and percutaneous core needle biopsy (CNB) regarding their accuracy...

Sir, Biopsies of suspicious lesions in the oesophagus can be readily performed via a flexible endoscope in most settings. However, structuring lesions may require a rigid endoscope under general anaesthesia or a percutaneous approach to successfully biopsy. The percutaneous approach however, is rarely used with upper gastrointestinal tract lesions. We describe the fine needle aspiration (FNA) o...

THE membership of the Society of Interventional Radiology (SIR) Standards of Practice Committee represents experts in a broad spectrum of interventional procedures from both the private and academic sectors of medicine. Generally Standards of Practice Committee members dedicate the vast majority of their professional time to performing interventional procedures; as such they represent a valid b...
