INTRODUCTION The aim of the study was to assess the diagnostic yield of ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in mediastinal or hilar adenopathy in: 1) staging of non-small cell lung cancer (NSCLC) (97); 2) other malignant neoplasms including: small cell lung cancer (SCLC), metastatic neoplasms and Hodgkin's disease (16); 3) NSCLC recurrence (7); 4) sarcoidosis and othe...

Over the past few years, the development of new technologies applied to different imaging modalities has determined a considerable impact on the diagnosis, staging and treatment of neoplastic diseases. Consequently an increase has been observed in patient survival as well as in cure rates. Among neoplasms, Hodgkin’s lymphomas (HL) and non-Hodgkin’s lymphomas (NHL) have been highlighted, with a ...

BACKGROUND No study on ultrasound-guided fine-needle aspiration (US-FNA) for the diagnosis of retrojugular lymph node has been reported. The present study aimed to introduce US-FNA techniques for retrojugular lymph node and to evaluate their efficacy. METHODS Of the 788 patients who underwent US-FNA of the cervical lymph node, 41 patients underwent US-FNAs of retrojugular lymph node and were ...

BACKGROUND AND PURPOSE The detection of cervical nodal metastases is important for the prognosis and treatment of head and neck tumors. The purpose of this study was to assess the ability of ADC values at 3T to distinguish malignant from benign lymph nodes. MATERIALS AND METHODS From July 2009 to June 2010, twenty-two patients (21 men and 1 woman; mean age, 49.8±9.5 years; age range, 28-66 ye...

Involvement of lymph nodes in various pathologies of the head and neck is frequent not only in malignant diseases but also in inflammatory conditions. As size criteria are not sufficient to define a lymph node as malignant, other criteria such as shape, central necrosis and extracapsular spread are other helpful signs. However, micrometastases are still an unresolved problem although new imagin...

The great majority of malignant peripheral nerve sheath tumors (MPNSTs) exhibit Schwann differentiation. Few MPNSTs with perineurial differentiation are also named malignant perineuriomas. Benign perineurioms were classified as intraneural, extraneural (soft tissue), sclerosing, and reticular variant. Histopathological features of intraneural perineurioma are individual nerve axons surrounded b...

Accurate lymph node characterization is important in a large number of clinical settings. We evaluated the usefulness of Contrast Enhanced Ultrasound (CEUS) in distinguishing between benign and malignant lymph nodes compared with conventional ultrasonography in the differential diagnosis of superficial lymphadenopathy.We present our experience for 111 patients enrolled in a single center.111 su...

I N T R O D U C T I O N Our previous data [1] established that human and animal hepatitis viruses actively replicate in the organs rich in reticular cells and lymphoid elements (liver, spleen, lymph nodes, bone marrow), and viremia especially in transmitted parentherally transmitted hepatits is connected both with the blood plasma and leukocytes [2]. In our present study, a blood leukocyte cult...
