Mycobacterium chelonae is a nontuberculous mycobacterium, classified as a Runyon type IV mycobacterium. In relation to humans, it is most commonly associated with tissue trauma or pulmonary infections. The majority of medical reports describe finding M. chelonae in the surgical setting, attributing infection to inadequate sterilization of surgical equipment. Symptoms are often nonspecific and include pain, erythema, and draining subcutaneous nodules and skin lesions. Therefore, the diagnosis of M. chelonae is often difficult to establish without prior suspicion of the disease, but can be confirmed with culture...

A 36 year-old male with no significant past medical history presented with lower extremity numbness, gait instability, and urinary and bowel retention of 4 weeks onset. Spine MRI revealed diffuse oedema of cervicothoracic spinal cord with several solid enhancing intramedullary lesions, suggestive of metastases. The (18)F-FDG PET/CT performed to identify the primary malignancy demonstrated mild hypermetabolic foci within the cervicothoracic cord, as well as a mildly hypermetabolic bilateral hilar lymphadenopathy and a mildly hypermetabolic pulmonary nodule, suggestive of sarcoidosis versus metastasis...

Thoracoscopic partial pulmonary resection for small peripheral nodules without using a stapler has been introduced to our hospital. After partial resection was performed with electrocautery, two different methods of surface sealing were used: a coagulation method (C method) with Soft Coagulation alone, and a coagulation-suturing method (CS method) with Soft Coagulation combined with continuous suturing. The clinical outcomes of the two methods were retrospectively compared in this study. The C method was used in 19 lesions of 18 cases, and the CS method was used in 20 lesions of 19 cases...

PURPOSE  : Lung cancer has the highest death rate among all cancers in the USA. In this work we focus on improving the ability of computer-aided diagnosis (CAD) systems to predict the malignancy of nodules from cropped CT images of lung nodules. METHODS: We evaluate the effectiveness of very deep convolutional neural networks at the task of expert-level lung nodule malignancy classification. Using the state-of-the-art ResNet architecture as our basis, we explore the effect of curriculum learning, transfer learning, and varying network depth on the accuracy of malignancy classification...

PURPOSE: Lung cancer is a major cause of cancer deaths, and the 5-year survival rate of stage IV lung cancer patients is only 2%. However, the 5-year survival rate of stage I lung cancer patients significantly increases to 50%. As such, spiral computed tomography (CT) scans are necessary to diagnose high-risk lung cancer patients in early stages. In this study, a computer-aided detection (CAD) system with radiomics was proposed. This system could automatically detect pulmonary nodules and reduce radiologists' workload and human errors...

To assess the efficacy of radioiodine therapy (RIT) and investigate the prognostic factors for patients with pulmonary metastasis secondary to differentiated thyroid carcinoma (DTC) through a retrospective study. A total of 80 patients with radioactive iodine-131 (I)-avid pulmonary metastasis from DTC treated with I from 2007 to 2014 at our institution entered the study. Treatment response was mainly measured by two parameters: serum thyroglobulin (Tg) levels and post-therapeutic I whole-body scan (WBS). Treatment variables were assessed for statistical significance using the univariate and multivariate analyses...

We report the first case of a 62-year-old man with a sclerosing pneumocytoma (SP) combined with a typical carcinoid (TC) and pulmonary adenocarcinoma in different lung lobes. Computed tomography revealed two nodules. The radiological diagnosis was primary lung cancer and a metastatic nodule; however, no enlarged lymph nodes were observed. Histological and immunohistochemical analyses defined the 1.7 cm nodule in the right upper lobe as adenocarcinoma and the 1.3 cm nodule in the left lower lobe as SP combined with TC...

Pulmonary meningothelial-like nodules are benign lesions that are often incidentally detected in surgically resected lung tissue. These nodules are usually asymptomatic and single. Rarely, they present as diffuse micronodules similar to the miliary pattern seen in tuberculosis or metastatic cancer. While diffuse meningothelial-like micronodules are usually benign, it is important to include this condition in the differential diagnosis of patients presenting with diffuse micronodules. We present the case of a 74-year-old asymptomatic female referred to the pulmonary clinic for evaluation of incidentally detected diffuse bilateral pulmonary nodules...

PURPOSE: To assess the feasibility of computed tomography (CT)-guided localization using a specific long dual-barbed hookwire in resection of pulmonary nodules with the size of 20mm or less by video-assisted thoracoscopic surgery (VATS) and to discuss the necessity of early treatment of small pulmonary nodules by VATS. RESULTS: All the nodules were successfully localized with hook wire under CT guidance. The 34 nodules had a mean diameter of 8.9 ± 3.8 mm and a mean distance from the most superficial edge of the nodules to the visceral pleura of 21...

The characteristic radiological signs of primary lung adenocarcinoma include notching, lobulation, spicular formation, pleural indentation and a bronchus leading to the nodule (bronchus sign). However, metastatic tumors rarely display such characteristics. We herein present two cases of breast cancer with sole metastatic pulmonary tumors recurring ~20 years after surgery for breast cancer. These patients exhibited radiographic signs specific to primary lung adenocarcinoma. Pulmonary metastatic nodular lesions occur through hematogenous spread; therefore, obtaining pathological specimens by transbronchial biopsy may be challenging...

Esophageal cancer is associated with poor prognosis. Its severity is linked to delayed diagnosis which is most often made once a cancer has metastasized, in Africa. Costal metastases are rare. We report a case of a 38-year old Senegalese patient with squamous cell carcinoma of the lower esophagus with lytic metastases to the ribs. Mrs. TD, aged 38, was admitted with painful swelling in right hemithorax associated with weight loss. The patient also reported mechanical dysphagia evolving during 4 months which had not motivated consultation...

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...

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...

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...

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...
