INTRODUCTION: The lung is the most common site of distal metastasis in patients with hepatocellular carcinoma (HCC), as seen in more than half of patients with extrahepatic disease. The incidence of pulmonary metastasis in all patients with HCC, however, remains low (between 4.5% to 20%). Their presence, nevertheless, contraindicates curative locoregional therapies. The role of staging chest computed tomography (CT) before locoregional treatment is not well defined. This study aimed to assess the utility of pre-treatment chest CT prior to locoregional therapy...

BACKGROUND: Initial reports of transbronchial cryobiopsy for diffuse parenchymal lung disease (DPLD) suggest the diagnostic yield approaches that of surgical lung biopsy (SLB) with an excellent safety profile. Centers performing cryobiopsy differ significantly in procedure technique; an optimal technique minimizing complications but still capable of diagnosing a wide range of DPLDs has not been established. We evaluated our practice of flexible bronchoscopic cryobiopsy in a primarily outpatient setting for patients who required a tissue diagnosis for DPLD of uncertain etiology...

AIM: To investigate the management for the indeterminate pulmonary nodules newly detected during the follow-up for nasopharyngeal carcinoma (NPC) patients. METHODS: Indeterminate pulmonary lesions were identified by searching medical records of NPC patients, who were followed-up with thoracic CT between April 2008 and February 2014. Indeterminate pulmonary nodules were defined as opacities that may be solitary or multiple, which were <1 cm in size and not calcified...

INTRODUCTION: Low dose CT screening for lung cancer has a high false positive rate with frequent discovery of indeterminate pulmonary nodules. Noninvasive biomarkers are needed to reduce false positives and improve risk stratification. A retrospective longitudinal evaluation was performed to assess chromosomal aneusomy in sputum via fluorescence in situ hybridization (CA-FISH) in four nested case-control studies. METHODS: ROC analysis resulted in two grouped cohorts: High Risk (CO High Risk and CO Nodule; 68 Cases, 69 controls) and Screening (ACRIN/NLST and PLuSS; 97 Cases, 185 controls)...

Indeterminate cell histiocytosis (ICH) is a very rare histiocytic disease. We reported a case of generalized ICH presenting as eroded papules and crusts, accompanied with intermittent fever, pulmonary disorder, lymphadenectasis in the mediastinum, and the retroperitoneum. The histopathology indicated a neoplasm that was composed of small nests of large cells with ample pale cytoplasm. Immunohistochemistry results and the absence of Birbeck granules led us to the diagnosis of ICH. Four months later, the patient died of anemia, ascites, and swelling of the limbs...

This 52-year-old male ex-smoker presented with a six-month history of progressive breathlessness and weight loss. He deteriorated acutely, and was admitted with severe type 1 respiratory failure. Apart from diffuse coarse crackles on chest auscultation, physical examination was unremarkable. High-resolution computed tomography (HRCT) showed diffuse cystic changes throughout the lungs. A diagnosis of pulmonary Langerhans cell histiocytosis (PLCH) was considered. Further workup identified a coincidental pancreatic lesion of uncertain significance, which remained indeterminate on magnetic resonance imaging (MRI) and on positron emission tomography (PET)...

OBJECTIVE: Patients with solitary pulmonary nodule (SPN) are usually sent to total-body positron emission tomography/computed tomography (PET/CT) examination with 18F-fluorodeoxyglucose (FDG). However, a segmental scan strategy may improve cost/effectiveness in this category of patients. CONCLUSION: A segmental PET/CT scan only at the chest level could be performed in patients with indeterminate SPN. Limiting the PET/CT field to the thoracic region would greatly affect on radiobiology, department organization and health-care costs...

Lung cancer is primarily caused by cigarette smoking and the leading cancer killer in the USA and across the world. Early detection of lung cancer by low-dose CT (LDCT) can reduce the mortality. However, LDCT dramatically increases the number of indeterminate pulmonary nodules (PNs), leading to overdiagnosis. Having a definitive preoperative diagnosis of malignant PNs is clinically important. Using microarray and droplet digital PCR to directly profile plasma miRNA expressions of 135 patients with PNs, we identified 11 plasma miRNAs that displayed a significant difference between patients with malignant versus benign PNs...

INTRODUCTION: Chagas disease (CD) is progressive and incapacitating, especially when cardiopulmonary function is affected. For example, respiratory muscle weakness can cause dyspnea upon exertion and fatigue, which may be exacerbated when it is associated with pulmonary hypertension (PH). The present study aimed to evaluate respiratory musculature, quality of life, anxiety, and depression among patients with indeterminate chronic CD and symptoms of PH. METHODS: All individuals completed a clinical evaluation, spirometry, a 6-min walking test, respiratory musculature testing using maximum inspiratory pressure (PImax) and maximum expiratory pressure (PEmax), the Hospital Anxiety and Depression Scale, and the SF-36 questionnaire...

We present the case of a patient with history of colon cancer, referred for the evaluation of indeterminate pulmonary nodules by F-FDG PET/CT. A dual-time point protocol was performed, and images were reconstructed using VUE Point HD and a Bayesian-penalized likelihood reconstruction algorithm (Q.Clear). Visually, the quality of the images was considered better when Q.Clear was used with β value of 200, uptake in the smallest nodule (7 mm) was clearly visible only with Q.Clear reconstruction, and uptake in the smaller nodules was best defined in the delayed time point acquisition...

OBJECTIVE: Tuberculous meningitis (TBM) is the most severe form of extra-pulmonary tuberculosis (TB) due to association of diseases with high rates of mortality and morbidity. Diagnosis continues to be a clinical challenge as microbiological confirmation is rare and time consuming resulting in delayed treatment. Xpert MTB/RIF assay is a rapid and simple test, which has been endorsed by World Health Organization as an initial diagnostic test for the diagnosis of TBM. However, evidence still lacks for its performance on cerebrospinal fluid (CSF) for the diagnosis of TBM especially from India...

INTRODUCTION: Interstitial lung disease (ILD) is currently the primary cause of death in systemic sclerosis (SSc). Thoracic high-resolution computed tomography (HRCT) is considered the gold standard for diagnosis. Recent studies have proposed several clinical algorithms to predict the diagnosis and prognosis of SSc-ILD. OBJECTIVE: To test the clinical algorithms to predict the presence and prognosis of SSc-ILD and to evaluate the association of extent of ILD with mortality in a cohort of SSc patients...

PURPOSE: Ventilation and perfusion (VQ) imaging is common following suboptimal CT pulmonary angiogram (CTPA) for pulmonary embolism (PE) evaluation; however, the results of this diagnostic pathway are unclear. The purpose of our study is to determine the incidence of PE diagnosed on VQ scans performed in patients with suboptimal CTPAs. METHODS: One hundred twenty-two suboptimal CTPAs with subsequent VQ scans within 1 week were retrospectively identified. VQ reports utilizing modified ​prospective investigation of pulmonary embolism diagnosis (PIOPED) and prospective investigative study of acute pulmonary embolism diagnosis (PISAPED) criteria were evaluated for presence of PE; intermediate probability, high probability, and PE present were considered PE positive...

It is difficult to differentiate Pneumocystis pneumonia (PCP) from rituximab-induced interstitial lung disease (RILD) in lymphoma patients with diffuse pulmonary infiltrates who are receiving rituximab-containing chemotherapy. Using a clinical scoring system, we aim to differentiate PCP from RILD who are receiving rituximab-containing chemotherapy. We reviewed the medical records of lymphoma patients who had received rituximab-containing chemotherapy between 2012 and 2015 in a tertiary hospital. Among 613 lymphoma patients receiving rituximab-containing chemotherapy, 97 (16%) had diffuse pulmonary infiltrates...

REVIEW
Ryan Wilson, Anand Devaraj
The large number of indeterminate pulmonary nodules encountered incidentally or during CT-based lung screening provides considerable diagnostic and management challenges. Conventional nodule evaluation relies on visually identifiable discriminators such as size and speculation. These visible nodule features are however small in number and subject to considerable interpretation variability. With the development of novel targeted therapies for lung cancer the diagnosis and characterization of early stage lung tumours has never been more important...
