Endoscopic Ultrasound-Guided Fine-Needle Aspiration Vs Fine-Needle Biopsy.
RM The primary goal of fine-needle aspiration is to acquire individual cells as opposed to tissue, which is the aim of fine-needle biopsy. Cells may not necessarily provide the stroma, or the associated architecture, of the surrounding tissue. Thus, if the surrounding architecture is needed to make a diagnosis, a fine-needle biopsy, which typically uses a core biopsy needle, should provide that.
متن کاملDiagnostic Fine Needle Aspiration in a Case of Riedel’s Thyroiditis
In Riedel’s thyroiditis, a rare chronic inflammatory disease of thyroid gland, fine needle aspiration is usually non-diagnostic because most often only follicular cells are obtained and not the fibrous material characteristic of this type of thyroiditis. Therefore the diagnosis is often only established by histopathologic study of the surgically obtained biopsy. The illustrated case is a 46-yea...
متن کامل[Computed tomography guided fine needle aspiration biopsies].
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...
متن کاملEndoscopic ultrasound-guided fine needle aspiration of a pericardial mass.
The prevalence of primary pericardial neoplasms ranges from about 0.001%– 0.007%. Primary malignant pericardial mesothelioma is extremely rare, with a reported prevalence of 0.0022% in autopsy series [1]. Although malignant mesothelioma is the most common primary malignancy of the pericardium, only approximately 350 cases of pericardial mesothelioma have been reported in the literature. Diagnos...
متن کاملEndoscopic Ultrasound-Guided Fine Needle Aspiration Accurately Diagnoses Smaller Pancreatic Neuroendocrine Tumors Compared To Computer Tomography-Guided Fine Needle Aspiration.
Introduction The role of EUS-guided FNA as a highly sensitive modality in the diagnosis of pancreatic adenocarcinoma is well documented. However, there is little published data on the role of EUS-FNA in diagnosing pancreatic neuroendocrine tumors (NETs). Objective The aim of this study is to compare the sensitivity of EUS-FNA to that of CT-FNA for diagnosing pancreatic NETs. Methods This is...
