OBJECTIVE Positron emission tomography (PET) is used increasingly in staging of non-small cell lung cancer (NSCLC) as a non-invasive tool. The role of the PET in mediastinal lymphatic staging of NSCLC is not clear. We aimed to demonstrate the efficacy of PET in determining mediastinal lymphatic metastasis by comparing the results of PET with mediastinoscopy. PATIENTS AND METHODS We performed ...

BACKGROUND The reported accuracy of transbronchial needle aspiration (TBNA) for mediastinal staging in non-small cell lung cancer (NSCLC) varies widely. We performed a meta-analysis to estimate the accuracy of TBNA for mediastinal staging in NSCLC. METHODS Medline, Embase, and the bibliographies of retrieved articles were searched for studies evaluating TBNA accuracy with no language restrict...

Myelolipoma is an uncommon tumor composed of adipose tissue and normal hematopoietic elements, and is most often found in the adrenal glands. We report a patient with a posterior mediastinal myelolipoma. The 68-year-old male patient showed a right lower mediastinal shadow in a chest X-ray. A computed tomographic scan demonstrated a right posterior mediastinal mass. Magnetic resonance imaging pr...

Neoplasms, cysts, inflammatory processes, and aneurysms may present as a mediastinal mass. New diagnostic techniques have recently become available for use in the investigation of a mediastinal mass, and we present a case illustrating the use of a transbronchial needle through a flexible bronchoscope to drain an accumulation of mediastinal fluid. So far as we are aware this is the first such re...

BACKGROUND Primary mediastinal goiters (PMG) are very uncommon; few cases were reported in the literature. PATIENT DESCRIPTION We report here two cases of mediastinal goiters that met all criteria of PMG. Transternal approach was necessary for complete removal and pathological diagnoses confirmed their adenomatous goiter nature. The rarity of their occurrence, their clinical characteristics a...
