Pulmonary infections from the environmental fungus Cryptococcus gattii ( C. gattii ) are notable for cryptococcomas, which are usually solitary and can be very large. As with infections with Cryptococcus neoformans (C. neoformans) patients can have concomitant cryptococcal meningitis; however, unlike for C. neoformans, infections with C. gattii often occur in immunocompetent patients. The highest published incidence of C. gattii infection has been in the Indigenous Australian population of Arnhem Land in the tropical north of the country...

Since the clinical introduction of magnetic resonance imaging (MRI), the chest has been one of its most challenging applications, and many physicists and radiologists have tried since the 1980s to use MR for assessment of different lung diseases as well as mediastinal and pleural diseases. Since then, however, technical advances in sequencing, scanners, and coils, adaptation of parallel imaging techniques, utilization of contrast media, and development of postprocessing tools have been reported by many basic and clinical researchers...

BACKGROUND: Solitary pulmonary nodules (SPNs) are common imaging findings. Many studies have indicated that F-fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG-PET/CT) is an accurate test for distinguishing benign and malignant SPNs. The aim of this study was to investigate the value of F-FDG-PET/CT in the diagnosis of malignant SPNs. METHODS: We systematically searched the PubMed and Embase databases up to March 2017, and published data on sensitivity, specificity, and other measures of diagnostic accuracy of F-FDG-PET/CT in the diagnosis of malignant SPNs were meta-analyzed...

Background: The incidental detection of solitary pulmonary nodule (SPN) is currently increasing due to the widespread use of computed tomography (CT) during the follow up in oncological patients or in screening trials. A quick and definitive histological diagnosis of these nodes is mandatory as, in case of primitive lung cancer, an early detection could improve both surgical results and prognosis. The minimally invasive pulmonary resection (MIPR) is the gold standard procedure for diagnosis and treatment of small lung nodules, but it can be difficult to localize deep nonpalpable nodes that lie in the lung parenchyma...

BACKGROUND: Pulmonary arteriovenous malformations (PAVMs) can be associated with life-threatening complications such as paradoxical embolization, cerebral abscess, and hemothorax. Therefore, all adults with PAVMs should be offered treatment. Percutaneous transcatheter embolization is the first-line treatment, but 5-25% of cases require further treatment due to persistence after embolization. Recently, the role of minimally invasive thoracic surgery as a definitive treatment has been evaluated...

BACKGROUND: Spontaneous regression has been defined as occurring when the malignant tumor mass partially or completely disappears without any treatment or as a result of a therapy considered inadequate to influence systemic neoplastic disease. Recently, studies have implicated immunological responses as likely being involved. We report a case of a patient with squamous cell carcinoma of the lung who experienced spontaneous regression following biopsy without other intervention. CASE PRESENTATION: A 57-year-old white man was referred to our pulmonary clinic after an incidental finding of a nodule in the lower lobe of his left lung...

BACKGROUND: Sclerosing pneumocytoma is a rare lung tumor that is usually recognized as a solitary nodule in the lung. Surgical removal is recommended; however, its clinical diagnosis is still an issue because it is difficult to differentiate from lung adenocarcinomas using a tiny sample obtained from biopsy. CASE PRESENTATION: We report a case of pulmonary sclerosing pneumocytoma located in the upper lobe of the right lung of a 34-year-old woman, which was diagnosed before surgery by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA)...

PURPOSE: Incidental solitary pulmonary nodules (SPNs) have become an increasingly common CT finding worldwide. Although there are currently many imaging strategies for evaluating SPNs, the differential diagnosis and management of SPNs remains complex because of overlap between benign and malignant processes. Moreover, transbronchial or percutaneous CT-guided biopsies do not always allow definitive diagnoses. In such cases, video-assisted thoracic surgery (VATS) has become the preferred surgical procedure for diagnosis and, in selected cases, for treatment of indeterminate SPNs...

Development of distant metastases from renal cell carcinoma (RCC) is a frequent occurrence and, in nearly 95% of the cases, secondary lesions present within 5 years following nephrectomy. We performed a left pneumonectomy for a peri-hilar lung mass in an 81-year-old man with history of kidney cancer, resected 37 years earlier. Histopathological examination revealed a solitary lung metastasis from RCC, relapsed after an extraordinary 37-year time interval. To the best of our knowledge, this remarkable case represents the longest time interval between radical nephrectomy for RCC and the occurrence of a pulmonary metastasis...

Byung Jin Kim, Kevin M Bradley, Manil Subesinghe
We present a case of a type Ia endoleak detected using F-FDG PET/CT 10 years after an abdominal aortoiliac endovascular aneurysm repair in an 83-year-old man. The F-FDG PET/CT scan was performed to evaluate a solitary pulmonary nodule but, in addition, demonstrated unexpected blood pool activity outside the stent graft and within the abdominal aortic aneurysm sac, indicating an endoleak; no FDG activity should be present within the aneurysm sac after stent graft placement. A subsequent CT angiogram confirmed the endoleak...

OBJECTIVES: The use of image-guided video-assisted thoracoscopic surgery for simultaneous localization and removal of small solitary pulmonary nodules in a hybrid operation room using C-arm cone-beam computed tomography is gaining momentum. We sought to assess the effect of the learning curve on procedural parameters and clinical outcomes of image-guided video-assisted thoracoscopic surgery for treating patients with small solitary pulmonary nodules. METHODS: Clinical variables and treatment outcomes of the 30 initial patients with solitary pulmonary nodules who were treated with image-guided video-assisted thoracoscopic surgery at Chang Gung Memorial Hospital (Taiwan) were prospectively analyzed...
