A 56-year-old female lettuce farmer was admitted to the hospital with a low-grade fever, worsening cough, and dyspnoea. A blood test revealed eosinophilia and a high serum IgE concentration. The 3-year follow-up showed that her total IgE level increased in December, peaked in May, and suddenly decreased in August. This result was consistent with the lettuce harvest season. A chest x-ray taken on admission showed an infiltrative shadow in the upper lung field. Chest CT revealed patchy ground glass opacity on the upper lung field and thickening of the bronchial wall...

Amiodarone is a commonly used antiarrhythmic agent but exhibits potential pulmonary toxicity. In this case series, we describe the clinical, radiographic, and histologic manifestations of three patients who developed interstitial lung disease (ILD) following amiodarone treatment for variable lengths of time with different dosages. The presentations on computed tomographic images and in pulmonary pathology differed among the three patients. All three had immediate discontinuation of amiodarone and received treatment with systemic corticosteroids...

There is no standard method of bronchoscopic local therapy for tracheal tumours. We herein present a case involving a 61-year-old woman who was diagnosed with tracheal mucosa-associated lymphoid tissue lymphoma and underwent resection by a bronchoscopic high-frequency electrosurgical snare. Few reports to date have described such use of high-frequency electrosurgical snares; however, they are effective for the treatment of tracheal tumours, especially pedunculated tumours.

Airway complications post lung transplant including ischaemia and dehiscence have a significant associated mortality (2%-4%) and morbidity. We describe a case of a 22-year-old female who developed significant bilateral anastomotic dehiscence with severe ischaemia following a bilateral single sequential lung transplant (BSSLTx). Following an intensive antimicrobial regimen, judicious bronchoscopic surveillance, and a prolonged inpatient stay, the dehiscence resolved without requiring further surgical intervention...

Pulmonary alveolar proteinosis (PAP) affecting transplanted lungs is not well recognized. Herein, we report two cases of PAP after lung transplantation (LTx). The first case was a 4-year-old boy with hereditary pulmonary fibrosis who underwent bilateral LTx and presented with respiratory distress on postoperative day (POD) 23. He was initially treated for acute rejection, died due to infection on POD 248, and was diagnosed with PAP at autopsy. The second case involved a 52-year-old man with idiopathic pulmonary fibrosis who underwent bilateral LTx...

We reviewed 11 patients with systemic sclerosis-related ILD who were referred to our Scleroderma Unit from January 2020 to January 2021 and started Nintedanib. Non-specific interstitial pneumonia (NSIP) was prevalent (45%), usual interstitial pneumonia (UIP) and UIP/NSIP pattern were both 27%. Only one patient had a history of smoking. Eight patients were on mycophenolate mofetil (MMF), eight were treated with corticosteroids (mean dose 5 mg/day of Prednisone or equivalent), and three were on Rituximab...

Alveolar-pleural fistulas that do not improve with thoracic drainage can be conservatively treated via endobronchial occlusion and pleurodesis, among other options. However, for inoperable cases, the treatment strategy to be followed, in the event that conventional conservative management fails, is unclear. Herein, we report a case of alveolar-pleural fistula managed by bronchial occlusion using a combination of Endobronchial Watanabe Spigot (EWS) and N-butyl-2-cyanoacrylate (NBCA). A 79-year-old man on prednisolone for interstitial pneumonia with autoimmune features was diagnosed with invasive pulmonary aspergillosis and Aspergillus pyothorax infection...

We present a case report of a 92-year-old patient with thoracic empyema, who was successfully treated via CT-guided insertion of a pigtail catheter. The advanced age of the patient often poses challenges in managing pyothorax due to limited physical activity and cognitive decline stemming from decreased activities of daily living. In instances where thoracic drainage is not feasible, the course of treatment is protracted and the prognosis is poor. Our case report exemplifies the successful treatment of pyothorax in a geriatric patient via CT-guided insertion of a pigtail catheter...

The current case report presents a 59-year-old man with imaging studies of the thorax showing nodular lesions in the lungs bilaterally. Based on radiographic and CT images, preliminary diagnoses for possible granulomatosis (tuberculosis) or pulmonary metastatic dissemination of a neoplastic process were made. An ultrasound-controlled transthoracic true-cut needle biopsy of a subpleural lesion was performed. Special staining with Congo red and examination with a polarizing light microscope for detection of amyloid confirmed the diagnosis of 'pulmonary nodular amyloidosis' by visualizing green birefringence...

Mepolizumab, a humanized anti-IL-5 monoclonal antibody used for severe asthma, results in a reduced rate of asthma exacerbation, improved lung function, reduced oral corticosteroid use, and improved quality of life. A 62-year-old man using high-dose inhaled corticosteroid visited our hospital because of poorly-controlled asthma. He had eosinophilia in peripheral blood and sputum, and high levels of fraction of exhaled nitric oxide. Therefore, he was treated with mepolizumab for severe asthma. Mepolizumab treatment resulted in significantly improved pulmonary function and reduced frequencies of asthma exacerbations...

TB itself is considered an independent risk factor for VTE; however, developing pulmonary embolism after medical thoracoscopy is extremely rare. Herein, we describe a 30-year-old previously healthy male with pleural tuberculosis developed a massive pulmonary embolism with subsequent cardiac arrest after a diagnostic medical thoracoscopy. Computed tomography pulmonary angiogram (CTPA) showed major right pulmonary embolism (PE). Unfortunately, the patient passed away despite resuscitation and extensive organ support in the intensive care unit (ICU)...

We presented the case of an adult patient with hyper-IgE syndrome (HIES) who was admitted acutely with a large hydropneumothorax from lung consolidation, a bronchopleural fistula and pleural infection. He has had recurrent pulmonary and skin infections since childhood and longstanding pneumatoceles. He was treated with systemic antibiotics and chest tube drainage. Administration of two doses of low-dose intrapleural therapy (1 mg tissue plasminogen activator and 5 mg deoxyribonuclease) allowed complete evacuation of his residual loculated pleural fluid, aided resolution of his infection without provoking a significant air leak and avoided the need for surgery...

BRAF mutations are uncommon in non-small cell lung cancer (NSCLC), accounting for less than 5% of all NSCLC cases. The utilization of targeted therapies in non-V600E BRAF mutant NSCLC is considered controversial, although non-V600E genotype is reported in ~50% of all BRAF mutant patients. We document the case of a 63-year-old patient with NSCLC harbouring a rare BRAF E501Q mutation, who had prolonged response to immunotherapy combined with chemotherapy in Vietnam. The patient was diagnosed with metastatic PD-L1-negative lung adenocarcinoma and received pembrolizumab plus chemotherapy as first-line treatment...

An 84-year-old man underwent right basal segmentectomy for primary lung cancer and developed empyema accompanied by a bronchopleural fistula (BPF). Emergency open-window thoracotomy was performed. Although the general and nutritional conditions improved, the fistula did not close naturally, and we planned to close it 6 months after surgery. In this report, we describe, for the first time, a novel method for closing BPF using an endobronchial Watanabe spigot (EWS), polyglycolic acid (PGA) sheet and N-butyl-2-cyanoacrylate (NBCA)...

In the light of this case, azygos and hemiazygos veins should be evaluated carefully in thorax CT scans. This rare case is also important in terms of the occurrence of AVT in a patient receiving rivaroxaban therapy. The outcomes and recurrence rates of these patients should also be reported for the decision of anticoagulant treatment.

A 69-year-old female Japanese patient presented with an abnormal shadow on chest computed tomography (CT). She had received a mastectomy 14 years prior. Under the diagnosis of primary lung cancer, left upper lobectomy was conducted. Pathology showed a lepidic adenocarcinoma with mediastinal lymph node metastases with pT2aN2M0. Upon retrospective analysis, the chest CT at the time of mastectomy depicted a ground-glass nodule (GGN) of less than 20 mm. Over the previous 10.5 years, the concentration of the central part of the GGN increased...

Adenoid cystic carcinoma (ACC) is primarily a salivary gland tumour that rarely involves the respiratory tract. A 58-year-old lady was admitted with worsening dyspnoea, cough and wheezing for 2 days. CT pulmonary angiogram was done due to persistent dyspnoea which revealed a 12 mm mass protruding into the posterior aspect of the trachea with multiple enlarged nodes. There was a complete collapse of the left lower lobe and right middle lobe with right upper lobe pulmonary embolism which was thought to be contributing to her hypoxia...
