Subsequent to the widespread use of multidetector computed tomography and growing interest in lung cancer screening, small pulmonary nodules are more frequently detected. The differential diagnosis for a solitary pulmonary nodule is extremely broad and includes both benign and malignant causes. Recognition of early lung cancers is vital, since stage at diagnosis is crucial for prognosis. Estimation of the probability of malignancy is a challenging task, but crucial for follow-up and further work-up. In addition to the clinical setting and metabolic assessment, morphological assessment on thin-section computed tomography is essential...

PURPOSE: To compare the diagnostic value of 99Tcm-MIBI- SPECT and 18F-FDG-PET/CT in differentiating benign from malignant solitary pulmonary nodules (SPNs). METHODS: 170 SPNs were involved in this study (78 with 99Tcm-MIBI-SPECT and 92 with 18F-FDG-PET/CT). Definite diagnosis of SPNs was determined by biopsy. The diagnostic efficiency of 99Tcm-MIBI-SPECT and 18F-FDGPET/ CT in differentiating benign from malignant SPNs was analyzed and compared. RESULTS: Seventy-eight patients with SPNs were examined with 99Tcm-MIBI-SPECT (26 with malignant SPNs and 52 with benign SPNs)...

Recent years have seen important advances in the diagnosis of invasive pulmonary aspergillosis (IPA), complemented by the introduction of new therapies. Despite this, IPA remains a major cause of infection-related mortality in patients with hematological diseases. There are two main reasons for this. First, diagnosis of IPA remains a challenge, since risk factors and the clinical, radiological and mycological presentations vary not only by fungal disease stage, but also by patient group (e.g. neutropenic versus non-neutropenic patients)...

Pulmonary cryptococcosis is most commonly reported in immunocompromised patients, whereas immunocompetent hosts are rarely affected and may be asymptomatic, resulting in reduced diagnostic performance of computed tomography (CT) imaging. Thus, the aim of the present study was to review the plain and contrast-enhanced chest CT scan findings of primary pulmonary cryptococcosis in immunocompetent patients, with the aim of improving the diagnosis of this type of pulmonary disease. In the present study, a total of 27 immunocompetent patients of clinically confirmed pulmonary cryptococcosis were analyzed retrospectively...

A 79-year-old man had undergone endoscopic colorectal resection for colon cancer and partial resection of right S2 for lung cancer in 2007. Two years later, enlargement of a small nodule in the right S10 detected by chest computed tomography was noted. Partial lung resection was performed in April 2009, and the pathological diagnosis was localized nodular pulmonary amyloidosis.

Pulmonary Langerhans' cell histiocytosis (PLCH) is a rare disorder of unknown cause characterised by the infiltration of the lungs and other organs by the bone marrow derived Langerhans' cells, which carry mutations of BRAF gene and/or NRAS, KRAS and MAP2K1 genes. It occurs predominantly in young smokers, without gender predominance. The disease is characterised by formation of eosinophilic granulomas with the presence of Langerhans' cells infiltrating and destroying distal airways. High-resolution computed tomography of the chest (HRCT) plays an outstanding role in PLCH diagnosis...

Every year, millions of patients are diagnosed with pulmonary nodules, and as increasing numbers of people undergo lung cancer screening, even more patients will be found to have a nodule. The vast majority of patients cannot benefit from the detection of a pulmonary nodule because most are benign. Accordingly, it is important to develop strategies to minimize harm, in particular the distress of a "near-cancer" diagnosis. In other settings, communication strategies are critical mediators of patient-centered outcomes for those with cancer and those at-risk of cancer...

As one of the important liquid biopsies, circulating tumor cells (CTCs) shows more and more clinical values in the treatment of lung cancer such as diagnostic screening, treatment evaluation, postoperative monitoring, and prognosis predicting etc. A large number of small pulmonary nodules patients are detected when screening the high risk population of lung cancer. However, small lung nodules are not equal to lung cancer, and 90%-95% of them are benign lesion, therefore, to accurately and correctly differentiate whether it is benign or malignant when patients firstly detected and treat a small pulmonary nodule is become a new opportunity and challenge for clinician...

Accurate assessment of pulmonary nodules can help to diagnose the serious degree of lung cancer. In most computed aided diagnosis (CADx) systems, the feature extraction module plays quite an important role in classifying pulmonary nodules based on different attributes of them. To precisely evaluate the malignancy of an unknown pulmonary nodule, this paper first proposes a novel pixel value space statistics map (PVSSM) for pulmonary nodules classification. By means of PVSSM this study can transform an original two-dimensional (2D) or three-dimensional (3D) pulmonary nodule into a 2D feature matrix, which contributes to better classifying a pulmonary nodule...

RATIONALE: Lymphomatoid granulomatosis is a very rare Epstein-Barr virus-driven lymphoproliferative disease. This disease has high mortality owing to its low incidence in conjunction with nonspecific presentations, which contribute to delays in diagnosis. PATIENT: An 87-year-old male had a week-long history of intermittent fever and general weakness. A chest radiograph showed multifocal patchy consolidations with nodular lesions. DIAGNOSES: Open lung biopsy using video-assisted thoracic surgery resulted in a diagnosis of grade III lymphomatoid granulomatosis...

The malignancy risk differentiation of pulmonary nodule is one of the most challenge tasks of computer-aided diagnosis (CADx). Most recently reported CADx methods or schemes based on texture and shape estimation have shown relatively satisfactory on differentiating the risk level of malignancy among the nodules detected in lung cancer screening. However, the existing CADx schemes tend to detect and analyze characteristics of pulmonary nodules from a statistical perspective according to local features only. Enlightened by the currently prevailing learning ability of convolutional neural network (CNN), which simulates human neural network for target recognition and our previously research on texture features, we present a hybrid model that takes into consideration of both global and local features for pulmonary nodule differentiation using the largest public database founded by the Lung Image Database Consortium and Image Database Resource Initiative (LIDC-IDRI)...

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) remains a poorly understood clinical entity. It is currently classified as a premalignant condition by the World Health Organization (WHO). Symptoms are similar to those associated with obstructive lung disease, including breathlessness and cough. The presentation is often initially ascribed to other diseases such as asthma or chronic obstructive pulmonary disease. Here, we present what we believe is the first described case of DIPNECH diagnosed by transbronchoscopic cryoprobe biopsy...
