A 16-year-old girl presented with intermittent left chest pain and breathlessness on exertion for last 4 months with one episode of haemoptysis. There has been loss of appetite and weight loss of 4 kg over a period of 1 month. A chest radiograph revealed a large mass like opacity with pleural effusion in the left lung field. Computerized Tomography scanning (CT scanning) and Positron Emission Tomography/Computerized Tomography scanning (PET/CT scanning) demonstrated a 7 cm round, cystic lesion in the anterior mediastinum...

Window-of-opportunity trials in malignant pleural mesothelioma (MPM) are challenging but can yield important translational information about a novel agent. We treated MPM patients (n=24) with 4 weeks of oral dasatinib followed by surgery with or without radiotherapy and then an optional 2 years of maintenance dasatinib. The primary endpoint was biomarker modulation of p-SrcTyr419. For all patients, the median PFS was 7.5 months and OS 19.1 months. No significant responses were seen after 4 weeks of dasatinib therapy, however, modulation of p-SrcTyr419 immunohistochemistry (IHC) scores (median (interquartile range) = 70 (37...

INTRODUCTION: The prevalence of incidental 18 F-fluorodeoxyglucose (FDG)-avid findings on positron emission tomography-computed tomography (PET/CT) has been extensively described. Few studies, however, have assessed the prevalence and significance of non-FDG-avid findings; pathology that is identified on review of the low-dose, non-contrast CT. The aim of this study was to determine the overall prevalence of non FDG-avid incidental findings on PET/CT and the prevalence of 'clinically significant' non FDG-avid pathology...

The risk factors and potential practice implications of radiation-induced pleural effusion (RIPE) are undefined. This study examined lung cancer patients treated with thoracic radiation therapy (TRT) having follow-up computed tomography (CT) or 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT. Increased volumes of pleural effusion after TRT without evidence of tumor progression was considered RIPE. Parameters of lung dose-volume histogram including percent volumes irradiated with 5-55 Gy (V5-V55) and mean lung dose (MLD) were analyzed by receiver operating characteristic analysis...

A 42-year-old woman with a newly diagnosed malignant thymoma underwent FDG PET/CT, which demonstrated an increased uptake in anterior mediastinal tumor and several pleural masses in the right hemithorax, compatible with "drop metastases." In addition, contrast-enhanced CT images showed hyperdense abnormality in T2 vertebral body, congruent with intensely increased FDG uptake, raising suspicion of skeletal metastasis. This is a rare but important potential pitfall either in CT and FDG PET/CT-a "false-positive" bony lesion not attributed to skeletal metastasis but to dilated internal thoracic vertebral venous plexus associated with collateral circulation due to superior vena cava syndrome...

PURPOSE: To compare dual-phase dual-energy CT (DE-CT) with FDG-PET/CT for predicting histopathological locoregional invasiveness of non-small cell lung cancers (NSCLCs). MATERIALS AND METHODS: We selected 63 consecutive patients with NSCLC lesions (37 males, 26 females; age range, 44-85 years; mean age, 69 years) who were evaluated preoperatively by both DE-CT and PET/CT at our institution. Postoperative microscopic invasiveness (lymphatic permeation, vascular invasion, and/or pleural involvement) was reviewed, and we defined locoregionally invasive tumors as those that had at least one positive finding of microscopic invasiveness...

BACKGROUND: To evaluate the added clinical value of (18)F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) scans to chest CT imaging in predicting the conversion to thoracotomy during video-assisted thoracoscopic surgery (VATS) lobectomy in patients with lung cancer. METHODS: This is a retrospective study of 235 consecutive patients who underwent planned VATS lobectomy for primary lung cancer between 2011 and 2015. CT images were interpreted in terms of the presence and the attenuation of peribronchial lymph nodes (PLN) and peribronchial cuffs of soft (PCS) tissue, pleural calcification, and parenchymal calcified nodule...

Malignant pleural mesothelioma is the most frequent primary neoplasm of the pleura and its incidence is still increasing.This tumor has a strong association with exposure to occupational or environmental asbestos, often after a long latent period of 30-40 years.Plain chest radiography (CXR) is usually the first-line radiologic examination, but the radiographic findings are nonspecific due to its limited contrast resolution and they need to be complemented by other imaging modalities such as computed tomography (CT), magnetic resonance Imaging (MRI), Positron emission tomography-computed tomography (PET-CT) and ultrasound (US)...

Pleural epithelioid hemangioendothelioma (EHE) is a rare malignancy of vascular-endothelial origin with non-specific symptoms and an unpredictable outcome. Diagnosis of this condition by imaging modalities is challenging, and no standard therapeutic approaches have been established in this regard. In this paper, we described the case of a patient with a low-grade fever, coughing and chest pain who underwent (18)F-FDG PET/CT after a positive thorax CT showing multiple bilateral calcified pulmonary nodules and extensive right-sided pleural effusion...

Malignant pleural mesothelioma (MPM) is a highly malignant pleural neoplasm with a dismal prognosis. Multimodality approach including surgery and chemotherapy are utilized to treat patients with resectable disease. Clinical staging allows for selection of patients for treatment strategies, but has not been found to be prognostic and is plagued by high interobserver variability. Tumor volume measurement on cross-sectional imaging has emerged as a potential quantitative tool with prognostic significance. This review focuses on volumetric assessment from cross-sectional imaging (CT, MRI, (18)F-FDG PET/CT) and the potential prognostic benefit and applications...

An ever increasing number of drugs directed as epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) bring a new revolution for non-small cell lung cancer (NSCLC) therapy, and many large scales of studies show that only people with EGFR-sensitive mutation can benefit from these drugs. The main method of EGFR mutation detection is to analyze the DNA sequence of EGFR, which can be the lung cancer tissue, pleural fluid tumor cells, circulating tumor cells and peripheral blood free DNA obtained by surgery or puncture, the biggest drawback is that the heterogeneity of EGFR mutation cannot be analyzed...

BACKGROUND: Epithelioid haemangioendothelioma (EHE) is a rare low-grade vascular neoplasm that can arise in the lung, liver, soft tissues or, less commonly, bone. Due to its low prevalence of less than one in a million and its non-specific clinical features, EHE is often misdiagnosed and managed inappropriately. Here we discuss the case of a 58 year-old gentleman with mediastinal EHE and review existing literature on pulmonary EHE (PEH). CASE HISTORY: A 58 year-old gentleman presented to our outpatient Clinic with chest discomfort and palpitations...

Malignant pleural mesothelioma (MPM) is a tumor of mesodermal origin that arises from the serosa of the pleura, peritoneum, pericardium or tunica vaginalis. MPM is well known to have a poor prognosis with a median survival time of 12 months. Accurate diagnosis, staging and restaging of MPM are crucial with [18F] flurodeoxy-D-glucose positron emission tomography (FDG PET/CT) playing an increasingly important role. Here we report a case of MPM with unusual contiguous soft tissue spread of the tumor along the dermal and fascial planes characterized by PET/CT...
