“…Its shape is proportional to the growth velocity of each part of the peripheral lung cancer and is blocked by the larger pulmonary vessels and bronchi [7,8]. The form of cavitary inner wall depends on whether the tissue necrosis of the tumour is even or whether there is a wall nodule.…”

Objectives: Form discordance of cavity walls (FDCW) and form concordance of cavity walls (FCCW) in multislice spiral CT (MSCT) were investigated to determine their value in differentiating between peripheral lung cancer cavities and single pulmonary tuberculous thick-walled cavities. An assessment of the role of multiplanar reconstruction (MPR) in detecting FDCW and FCCW was also performed. Methods: MSCT cross-sectional images of 116 consecutive cases (including 60 cases with available MPR images) with peripheral lung cancer cavities and 118 consecutive cases (including 62 cases with available MPR images) with single pulmonary tuberculous thick-walled cavities (wall thickness .3 mm) were retrospectively analysed. According to the characteristics of cavitary internal and external walls on MSCT, these cavities were divided into two types (FDCW and FCCW). FDCW was further divided into three subtypes (FDCW-I, FDCW-II and FDCW-III); FCCW was further divided into two subtypes (FCCW-I and FCCW-II). Results: On the cross-sectional and MPR images, the total detection rate of FDCW-I and FDCW-III in peripheral lung cancer cavities was 76.7% (89/116) and 93.3% (56/60), respectively, whereas the total detection rate of FCCW-I and FCCW-II in single pulmonary tuberculous thick-walled cavities was 75.4% (89/118) and 91.9% (57/62), respectively. Conclusions: FDCW-I, FDCW-III, FCCW-I and FCCW-II were valuable in differentiating between peripheral lung cancer cavities and single pulmonary tuberculous thick-walled cavities. MPR could improve the detection of FDCW-I and FDCW-III in peripheral lung cancer cavities and FCCW-I and FCCW-II in single pulmonary tuberculous thick-walled cavities. Cavities are frequent image findings in a variety of pulmonary diseases. Many of these diseases, including both lung cancer and pulmonary tuberculosis, can form a cavity during their course [1][2][3]. The cavities formed during these two particular diseases are difficult to distinguish [1,4,5], particularly in the case of peripheral lung cancer cavities and single pulmonary tuberculous thick-walled cavities. Although numerous studies have been conducted in this area, there is still no pertinent literature on the differential diagnostic value of form concordance or discordance of cavitary internal and external walls obtained from multislice spiral CT (MSCT). The aim of this study was to analyse MSCT manifestations of form discordance of cavity walls (FDCW) and form concordance of cavity walls (FCCW) to ascertain their value in differentiating between peripheral lung cancer cavities and single pulmonary tuberculous thick-walled cavities. In addition, the role of multiplanar reconstruction (MPR) in detecting FDCW and FCCW is assessed. Between May 2006 and June 2008, 116 consecutive cases of peripheral lung cancer cavities confirmed using pathological specimens obtained through surgical resection (n580) or CT-guided transthoracic needle aspiration (n536) were retrospectively analysed. The patients ranged in age from 36 to 76 years (mean age, 58 years...

“…Part solid or solid presentations have been correlated to alveolar collapse (12) or rare mucinous types. A recent case report showed that gravity may increase artificially the density of pure GGO nodules located in the posterior lung Mucinous BAC Part solid GGO / solid Consolidation malignant nonsolid nodules were described in a small series (20): increase in size of the nonsolid area (n = 5); reduction in size of the nonsolid area coupled with appearance of a solid component (n = 2); stable dimension of the nodule but progression from non-solid to a part-solid nodule (n = 1).…”

The present manuscript is a summary of two lectures which were given respectively by B. Weynand and G.R. Ferretti. The new classification of lung adenocarcinomas has changed the view of the radiologists and the pathologists espe cially regarding the former bronchioloalveolar carcinoma (BAC). The aim of this paper is to correlate radiological and histopathological images according to the 2011 classification for lung adenocarcinoma proposed by the Interna tional Association for the Study of Lung cancer, the American Thoracic Society and the European Respiratory Society and to draw attention to the way these lesions can be approached preoperatively.

“…The tumor is more frequently discovered by radiographic examination. Radiologists very often describe the computed tomography (CT) scan appearance of a pure BAC as that of ground-glass opacity (GGO) 8,9 ; however, there is no consensus among radiologists on a defined radiographic appearance for BAC, mostly because not all pure GGO lesions, when excised, correspond to pure BAC histologically. Studies of radiographic-histologic correlations have showed that pure GGO can have a component of invasive adenocarcinoma admixed with a BAC growth pattern, 10 and invasive adenocarcinomas, such as pure papillary type, can present radiographically as a GGO.…”
