Abstract OBJECTIVES The aim of this study is to evaluate the efficacy of chest computed tomography (CT) to predict the pathological stage of thymic epithelial tumours (TET) using the recently introduced tumour, node and metastasis (TNM) staging with comparison to the modified Masaoka staging. METHODS Preoperative chest CT examinations in cases of resected TET with sampled lymph nodes (2006–2016) were retrospectively reviewed by 2 thoracic radiologists and radiologically (r) staged using both staging systems. A thoracic pathologist reviewed all cases for the pathological (p) stage. Concordance between r-staging and p-staging was assessed by % agreement and unweighted kappa statistics. Associations between r-stage and p-stage with outcomes were assessed using the Cox proportional hazards regression. RESULTS Sixty patients with TET were included (47 thymomas, 12 thymic carcinomas and 1 atypical carcinoid tumour). Sixteen patients (26.7%) had received neoadjuvant therapy. Fifty-four patients (90.0%) had complete resection. The overall agreement between the r-stage and p-stage was 66.7% (κ = 0.46) for TNM staging and 46.7% (κ = 0.30) for modified Masaoka staging. Agreement between r-assessment and p-assessment of the T, N and M components of the TNM stage was 61.7% (κ = 0.28), 86.7% (κ = 0.48) and 98.3% (κ = 0.88), respectively. CT overstaged 12 patients (20.0%) for TNM staging and 12 patients (20.0%) for modified Masaoka staging and understaged 8 (13.3%) and 20 (33.3%) patients for TNM staging modified Masaoka staging, respectively. The r-TNM staging accuracy was lower for patients with neoadjuvant therapy (50.0% with vs 72.7% without). During a median follow-up of 2.6 years (range 0.1–10.5 years), 12 patients had metastases and/or recurrence; 11 patients died (4 of disease). The r-TNM stage and modified Masaoka stage were associated with overall survival and progression-free survival (P < 0.001). CONCLUSIONS Preoperative chest CT is able to accurately predict p-TNM stage in two-thirds of surgically resected TET, with an agreement between radiological staging and pathological staging superior to the modified Masaoka staging.

Pneumothorax, defined as the presence of air in the pleural space, is usually classified as spontaneous or traumatic; it is unusual for pneumothorax to be categorized as being acute or chronic. Even if conservative treatment is chosen, the pneumothorax is cured when air in the pleural space dissolves into the venous blood. A 50-years-old Japanese man with no prior medical history was referred to our department with a right pneumothorax and two rightsided pulmonary nodules on chest X-ray and CT. The chest radiographs of past mass screening which was taken four years ago showed right pneumothorax and right-sided pulmonary nodules. From then, all chest radiograph and chest computed tomography showed right pneumothorax and pulmonary nodules. But he underwent no medical interventions. We designed to perform an operation for a treatment of right pneumothorax and the diagnosis of pulmonary tumors. We underwent right upper lobectomy and pleural decortication under video assisted thoracic surgery. We obtained pathological diagnosis of inflammatory pseudotumor and surrounding atelectasis. He was cured from pneumothorax and pulmonary tumors. A unique case of spontaneous pneumothorax presenting with a pleural air space that was confirmed by chest radiographs and computed tomography examinations over a 4-year period is reported.

Primary spontaneous pneumothorax is defined as the presence of air in the pleural space with no precipitating cause and is four times less likely to occur in women than in men1,2. Common causes for spontaneous pneumothorax in females include: interstitial pneumonia, primary lung cancer and lung metastasis, and asthma3.  An uncommon cause for secondary spontaneous pneumothorax is catamenial pneumothorax, which is associated with thoracic endometriosis. The word “catamenial” is derived from the greek word “katamenios” meaning monthly recurrence.4 Catamenial pneumothorax refers to recurrent spontaneous pneumothorax during menstruation in the absence of concomitant respiratory disease5.

Pneumothorax is defined as the presence of air in the pleural space due to: a) communication be- tween alveolar spaces and pleura; b) direct or indi- rect exchange of air between the atmosphere and the pleural space; or c) the presence of gas produc- ing organisms in the pleural space. From the clinical and etiological standpoint the pneumothorax [...]

Lung Condition

Pneumothorax is defined as the presence of air within the pleural space. Pneumothoraces are divided into spontaneous and traumatic categories, depending on the presence or absence of preceding trauma. Spontaneous pneumothoraces are subclassified as primary or secondary: a primary spontaneous pneumothorax (PSP) occurs in a person without underlying lung disease, whereas a secondary spontaneous pneumothorax (SSP) takes place in a person who has an underlying lung condition such as COPD or asthma. Tension pneumothorax is a medical emergency where air entering the pleural space on inspiration is unable to escape on expiration, causing mediastinal shift and cardiovascular compromise.
