BACKGROUND/AIM: Surgical resection can be applied in cases of early-stage small-cell lung cancer (SCLC). Predicting the histology of SCLC and discriminating SCLC from other histologies would be useful for determining the optimal treatment strategies for small pulmonary nodules that have not been preoperatively diagnosed. MATERIALS AND METHODS: The study population included 17 patients with resected SCLC and 296 patients with adenocarcinoma (ADC) whose preoperative CT were available...

COMMENT
Tawee Tanvetyanon, Theresa A Boyle
Multifocal pulmonary adenocarcinomas are increasingly encountered in clinical practice, in part due to the increased availability and improvement in the thoracic imaging. Recognized as a distinct entity in the upcoming 8(th) edition of American Joint Commission on Cancer (AJCC) staging system, multifocal adenocarcinomas exhibit several unique features such as the characteristic appearance of multiple ground glass opacities or nodules in computerized tomography (CT). Recent studies have suggested that the vast majority of these malignant lesions are genetically independent even when occurring synchronously in a single patient...

BACKGROUND: Primary pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma is a low-grade B cell lymphoma that is a type of non-Hodgkin lymphoma and a type of primary pulmonary malignant lymphoma. MALT lymphomas affecting the lung show various findings on chest computed tomography, which range from typical nodules or areas of consolidation to findings that are extremely rare in pulmonary MALT lymphomas, such as pure ground-glass opacities throughout the lung. CASE PRESENTATION: A 35-year-old woman was found to have a few shadows with ground glass opacities on chest computed tomography (CT) in 2012...

OBJECTIVES: The method of evaluating ground glass opacity (GGO) on thin-section computed tomographic (CT) scans is an issue of debate in early lung cancer. The term 'part-solid tumour' is frequently misused, and there is no consensus for its definition. METHODS: A retrospective study was conducted on 775 consecutive patients with resected lung adenocarcinoma of clinical stage IA between 2008 and 2013. Part-solid tumours (PSTs) having a ground glass component and consolidation were divided into two categories using the radiological criterion of a consolidation-to-tumour (C/T) ratio of 0...

Since the description of cryptogenic organising pneumonia (COP) in 1983 by Davison et al. and the subsequent report on bronchiolitis obliterans organising pneumonia (BOOP) by Epler et al., some reports have been published regarding the imaging features of organising pneumonia (OP). In this pictorial review, we aim to describe different manifestations of OP on high-resolution computed tomography (HRCT) accompanied by their histopathological correlations for a better comprehension of the radiological findings pathomechanism...

Hepatic epithelioid hemangioendothelioma (HEH) is a rare tumor of vascular endothelial origin. Spontaneous rupture of HEH is a life-threatening complication and is extremely rare. HEH has variable malignant potential, and the clinical diagnosis remains challenging. Here we report a case of HEH with spontaneous rupture. A 44-year-old man presented with constant cutting pains over the right upper abdomen after eating. He had hemoptysis 11 d previously. Diagnostic abdominal puncture demonstrated active bleeding...

The main challenges of imaging for endometriosis are the detection of nonovarian disease and the evaluation of the extension of the disease into pelvic structures. Transvaginal ultrasonography (TVS) has been proposed as the first-line imaging technique because it allows extensive exploration of the pelvis. The "typical" endometrioma is a unilocular cyst with homogeneous low-level echogenicity (ground glass echogenicity) of the cyst fluid. The use of color Doppler helps avoid classifying malignancies as endometriomas, defining the presence of vascular flow in papillations...

REVIEW
Mong-Wei Lin, Jin-Shing Chen
Low-dose computed tomography (LDCT) screening has increased the detection rate for small pulmonary nodules with ground-glass opacity (GGO) in the peripheral lung parenchyma. Minimally invasive thoracoscopic surgery for these lung nodules is challenging for thoracic surgeons, and image-guided preoperative localization is mandatory for their successful resection. Image-guided localization methods primarily include two imaging tools: computed tomography (CT) and bronchoscopy. These different methods may use different localized materials, including hookwires, dyes, microcoils, fiducial markers, contrast media, and radiotracers...

Percutaneous cryoablation under imaging guidance has been proved to be a safe and effective method for ablation and debulking of tumors, providing radical cure or palliation, as the case may be, for patients with different stages of disease. The local control rate is high with cryoablation, and the complications are usually controllable, making it a reasonable choice in lung cancer treatment. In this paper the technique and mechanism of action of cryoablation are summarized, and studies performed on the application of percutaneous cryoablation in various stages of lung cancer are reviewed...

BACKGROUND: Screening for lung cancer using high resolution computed tomography (CT) has produced encouraging early results. Extremely small nodules and non-palpable areas of opacifications are able to be detected, but pose a challenge to the thoracic surgeon trying to resect these areas. METHODS: Forty five patients with ground glass opacifications (GGOs) or small pulmonary nodules underwent pre-operative CT-guided placement of methylene blue dyed agar and/or hook wire needle localization prior to thoracoscopic resection...

PURPOSE: Recent work has shown that current TCM profile designs boost detection of low-contrast lung lesions in the lung apices, but yield reduced detection performance in the mid and lower lung regions relative to fixed tube current cases. This observed imbalance suggests that the TCM scheme might be tailored in new ways to maximize nodule detection throughout the entire lung. In this work, we begin a preliminary investigation into custom TCM profiles in an attempt to achieve uniform lesion detection throughout the extent of the lung...

Respiratory bronchiolitis-associated interstitial lung disease (RBILD) is a distinct clinical-pathological disease described almost exclusively among cigarette smokers. Normally, the most common manifestations in computed tomography findings of RBILD are central and peripheral bronchial wall thickening, centrilobular nodules, ground glass opacity, and mild centrilobular emphysema in the upper lobes. In this study, we report a current smoker presenting with diffuse ground glass opacity in the entire lungs along with paraseptal emphysema...
