“…Previous studies have been carried out on the use of CT performance in differentiating peripheral lung cancer cavities and single pulmonary tuberculous thick-walled cavities. These earlier works focused primarily on whether the side wall of the cavity was lobulated, the inner wall had rugosity, the cavity wall was even or uneven or whether there were other features such as spiculate signs, processus spinosus, pleura indentation signs, calcification foci, satellite focus, bronchial dissemination focus and contrastenhanced CT characteristics, among others [9][10][11][12][13].…”

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...

“…The evidence of previous primary pulmonary TB was present in 3 patients (cases 2, 3 and 6) in this study. Multiple cavities suggest an underlying immune compromised condition or the possibility of multidrug resistant tuberculosis (MDR-TB) (14,15).

Background: Cavitary pulmonary tuberculosis (TB) is rare in children. Objectives: The aim of this study was to evaluate the characteristics of cavitary pulmonary TB in children. Patients and Methods: This retrospective study was conducted on 97 children less than 15 years old with pulmonary TB to assess the clinical characteristics and radiographic findings of patients with cavitary lesions. Results: Seven (7%) out of 97 children had cavitary pulmonary TB. All patients were between 13 and 14 years old with a female/male ratio of 2.5/1. The most common symptom was cough. All patients had positive sputum smear results. Cavitary lesions were seen in the right upper lobe in six cases and multiple cavities were observed in two cases. Conclusions: This finding strongly suggests that older children with pulmonary TB can be more at risk than younger ages. Special attention must be paid to the prevention and treatment of TB in older children, particularly females.

“…Authors mentioned that although a similar appearance can be seen in patients with atypical mycobacterial or bacterial bnonchopneumonia, these CT findings, if present, can be helpful in diagnosing tuberculosis in children (18). Centrilobular nodules of groundglass attenuation was reported among the CT findings with TB (9,19). Tuberculosis during early childhood, in particular, there is a continuum between tuberculosis infection and disease.…”
