Background: Tissue diagnosis of anterior mediastinal tumors is very important for making correct therapeutic decision. To evaluate the value of performing percutaneous core needle biopsy in these tumors, we decided to perform this study. Materials and Methods: CT guided core needle biopsy was performed in 17 patients with anterior mediastinal tumor during an18-month period. The biopsy specimens...

Abstract Background The nature of opaque lesions such as effusions, atelectasis, masses, and consolidations can be clarified by sonography. This study investigated the sensitivity accuracy ultrasound-guided percutaneous core needle biopsy in different thoracic tumors (lung, pleural, chest wall, mediastinal). Results Sixty patients underwent transthoracic peripheral masses with a Tru-Cut big bor...

Percutaneous fine-needle aspiration biopsy (FNAB) is a well-established and useful procedure in the diagnosis of lung squamous cell carcinoma (LSCC). Tumor seeding has been shown to be a potential risk. We report the case and management of a 78-year-old patient affected by LSCC who developed a chest wall metastasis in a straight line from the primary lesion along the FNAB needle track. Although...

Purpose Microwave ablation combined with concurrent biopsy has been used for lung cancer. Frozen section (FS) diagnosis is an important supplement the final pathology (FP). Thus, a retrospective study was conducted to evaluate concordance between FS examination and FP in computed tomography (CT)-guided of cancer.Materials methods Patients who underwent percutaneous transthoracic needle biopsies...

We describe the case of pulmonary hyalinizing granuloma in a 34-year-old asymptomatic man who presented with a pulmonary nodule apparent by chest radiography and computed tomography (CT). He had a history of previous treatment for tuberculosis. His laboratory data were normal. Bronchoscopy and CT-guided percutaneous transthoracic fine needle aspiration cytology were inconclusive. The diagnosis ...

BACKGROUND Malignancies located in the upper middle mediastinum usually do not have a sufficiently large acoustic window to permit a conventional ultrasound guided parasternal biopsy. This study was concerned with an alternative approach whereby ultrasound is applied through the supraclavicular paratracheal window to allow percutaneous biopsy of middle mediastinal malignancies. METHODS Fiftee...

Differential diagnosis between pancreatic cancer and chronic pancreatitis is still difficult to establish. In 63 patients with suspected pancreatic neoplasm we performed: serum CA 19-9 assessment, abdominal ultrasound. CT scan and CT-guided pancreatic percutaneous fine-needle biopsy. The conclusive diagnosis was pancreatic cancer in 40 patients and chronic pancreatitis in 23 patients. With rega...
