Bronchial foreign body is a common health problem worldwide, types of bronchial foreign bodies are variegated, depending on patient age and cultural background including religious beliefs as well as alimentary habits. However, misdiagnoses caused by regional dietary correlation factors were rarely concerned. In this case, a 52-year-old woman with aggravated cough and hemosputum took thoracic CT scan twice and flexible fiberoptic bronchoscopy 5 times, which all revealed the chronic pulmonary inflammation. Furthermore, the biopsies showed bronchial granulation nodule formation...

Uniportal video-assisted thoracic surgery (VATS) lung wedge resection usually requires three devices, thoracoscope, lung retracting instrument and an endo-stapler cutter to perform the procedure. With advances in miniaturization of the thoracoscope and lung retracting instruments, a major limitation to operating through a smaller uniportal incision has become the endo-stapler. We describe the surgical technique for uniportal VATS laser lung resection which uses a much narrower laser catheter device to replace the endo-stapler for resection...

BACKGROUND: Identification of small peripheral lung nodules during minimally invasive resection can be challenging. Electromagnetic navigational bronchoscopy (ENB) with injection of dye to identify nodules can be performed by the surgeon immediately prior to resection. We evaluated the effectiveness of ENB with dye marking to aid minimally invasive resection. METHODS: Patients with peripheral pulmonary nodules underwent ENB before planned thoracoscopic or robotic-assisted thoracoscopic resection...

We established two patient derived tumor cells (PDCs) from right and left pulmonary metastatic lesions respectively of a patient with giant cell tumor. At that time, patient-derived tumor cells from right and left surgical specimens were collected and cultured. High-throughput screening (HTS) for 24 drugs was conducted with a micropillar/microwell chip platform using giant cell tumor PDCs. Using 6 doses per drug in 6 replicates for giant cell tumor PDCs, the dose response curves and corresponding IC50 values were calculated from the scanned images using the S+ Chip Analyzer...

A 71-year-old man was admitted to our hospital for dyspnea, which had worsened over a period of more than six months. He was previously diagnosed as having cryptogenic organizing pneumonia, and was treated with steroids in another hospital. He had complained of worsening dyspnea, despite the treatment. We performed video-assisted thoracoscopic surgery because of the high level of lactate dehydrogenase and inconsistency of the usual interstitial pneumonia pattern. Pathologic specimens showed atypical lymphocytes confined to the pulmonary capillaries...

BACKGROUND: Granulomatosis with polyangiitis (GP) is a systemic necrotizing vasculitis with multi-organ involvement that primarily affects the respiratory tract and the kidneys. Fever in these patients is an indicator of activity; however, if it arises in isolation, the physician should exclude other causes. CLINICAL CASE: Male patient admitted due to an unexplained fever and weight loss; it was diagnosed GP by a history of pauci-immune glomerulonephritis, fixed pulmonary nodules and chronic sinusitis of four years of evolution; however, the fever persisted despite treatment and in the absence of infection...

OBJECTIVE: Following incidental lung nodules with interval CT scanning is an accepted method to detect early lung cancer, but delayed tracking or failure to track is reported in up to 40% of patients. METHODS: Our institution developed and implemented an automated lung nodule registry tracking system. This system uses a code at the time that a suspicious nodule is discovered to populate the registry. Suspicious nodules were defined as any nodule, solid or ground glass, <3 cm that the radiologist recorded as a potential malignancy or recommended for follow-up imaging...

A 68-year-old woman presented with visible haematuria. Ultrasonography and triphasic CT revealed a 2.6 cm mass in the lower pole of the left kidney. A biopsy suggested low-grade renal cell carcinoma. Radical nephrectomy was performed and revealed an epithelioid angiomyolipoma. At year 3, the patient developed ductal carcinoma of the right breast and underwent a wide local excision and sentinel lymph node biopsy followed by chemotherapy and radiotherapy. 4 months later, she was noted to have a 1.6 cm nodule in the middle lobe of her right lung...

Angiostrongylus vasorum (A. vasorum) is an important emerging disease of canidae. Cardiorespiratory signs are common in affected dogs, therefore thoracic imaging is critical for diagnosing and monitoring disease. Descriptions of thoracic computed tomography (CT) findings in dogs naturally infected with A. vasorum are currently lacking. Aims of this multicenter, retrospective study were to describe thoracic CT findings in a group of dogs with confirmed disease, determine whether any changes were consistent among dogs, and propose standardized terms for describing thoracic CT findings...

Recurrent respiratory papillomatosis (RRP) is a benign disease of the upper aero-digestive tract caused by human papillomavirus (HPV) infection, which affects children and young adults. The aim of this review is to describe the main etiological, epidemiological, clinical, diagnostic, and treatment aspects of RRP. Most infections in children occur at birth, during passage through the birth canals of contaminated mothers. In adults, HPV is transmitted sexually. Papillomas usually appear as exophytic nodules, primarily in the larynx, but occasionally involving the nasopharynx, tracheobronchial tree, and pulmonary parenchyma...

To investigate the performance of combined 18F-FDG Positron Emission Tomography/Computed Tomography with high-resolution CT for differentiating invasive adenocarcinoma from adenocarcinoma in situ (pre-invasive lesion) or minimally invasive adenocarcinoma in stage IA lung cancer patients with solitary ground-glass opacity nodules. This retrospective study enrolled 58 consecutive stage IA pulmonary adenocarcinoma patients with solitary ground-glass opacity nodules. The characteristics and measurements of the ground-glass opacity nodules as pure ground-glass opacity nodules and mixed ground-glass opacity nodules in the pre-invasive or minimally invasive adenocarcinoma and invasive adenocarcinoma groups on Positron Emission Tomography/Computed Tomography and high-resolution CT were compared and analyzed...

The introduction of lung cancer screening programs will produce an unprecedented amount of chest CT scans in the near future, which radiologists will have to read in order to decide on a patient follow-up strategy. According to the current guidelines, the workup of screen-detected nodules strongly relies on nodule size and nodule type. In this paper, we present a deep learning system based on multi-stream multi-scale convolutional networks, which automatically classifies all nodule types relevant for nodule workup...

RATIONALE: The USPSTF recommends lung cancer screening with low-dose chest CT scans (LDCT) for a well-defined high-risk population. Data on the frequency and impact of incidental findings on LDCT scans performed within a centralized lung cancer screening program has not been reported. OBJECTIVES: Previous studies have reported IFs in the setting of clinical trials. We present our findings in a real clinical setting where the decision to manage these findings may depend on factors that are not captured in a research trial such as disclosing IFs, patient preferences, severity of comorbidities, and physician expertise...

BACKGROUND: Alveolar echinococcosis is a potentially lethal zoonosis caused by larval forms of the tapeworm Echinococcus multilocularis. Humans are aberrant intermediate hosts who become infected by ingestion of egg-contaminated food or water or via physical contact with domestic or wild animals that carry the parasite in their small intestine. In humans, the disease usually affects the liver and can spread to other organs causing metastatic infiltration. In this report, we describe an advanced presentation of human alveolar echinococcosis mimicking metastatic malignancy...
