OBJECTIVE: Because of decreased tactile sensation with thoracoscopic approaches to biopsy, localization preoperatively and intraoperatively is important for successful biopsy. Our study evaluated the technique of combined computed tomography-guided hookwire and methylene blue localization. METHODS: Seventy-five patients from November 2007 to August 2013 who underwent combined Hawkins hookwire and methylene blue localization of 76 total pulmonary nodules before video-assisted thoracic surgery-guided wedge resection were retrospectively reviewed...

Primary lung lymphoma (PLL) is a rare type of lymphoma confined to the lung at the time of diagnosis. Pulmonary diffuse large B cells lymphoma (P-DLBCL) is the second most common type of PLL and it usually appears radiologically as solitary or multiple nodules or areas of consolidation. We present the case of a 63-year-old Caucasian male who developed severe acute respiratory failure and diffuse ground glass opacities (GGO) on chest computerized tomography. Diffuse GGO may be the radiological expression of very different diseases, ranging from infectious processes to interstitial lung diseases (ILDs) and neoplastic diseases...

Introduction : Sarcoidosis is a granulomatous disease with unknown cause that can vary from an asymptomatic condition. Almost half of the patients with sarcoidosis have no symptoms. In this article, we describe a sarcoidosis patient with lung and liver engagement; it may be confused with metastasis. Case report : A 39-year-old man, known as hypothyroidism who had come to the emergency ward with dyspnea and coughing after exposure to detergents in a closed environment A 39-year-old man, known as hypothyroidism who had come to the emergency ward with dyspnea and coughing after exposure to detergents in a closed environment...

RATIONALE AND OBJECTIVES: Chest tomosynthesis has been suggested as a suitable alternative to CT for follow-up of pulmonary nodules. The aim of the present study was to investigate the possibility of detecting pulmonary nodule growth using chest tomosynthesis. MATERIALS AND METHODS: Simulated nodules with volumes of approximately 100 mm3 and 300 mm3 as well as additional versions with increasing volumes were created. The nodules were inserted into images from pairs of chest tomosynthesis examinations, simulating cases where the nodule had either remained stable in size or increased in size between the two imaging occasions...

BACKGROUND AND OBJECTIVE: Among all malignant tumors, lung cancer ranks in the top in mortality rate. Pulmonary nodule is the early manifestation of lung cancer, and plays an important role in its discovery, diagnosis and treatment. The technology of medical imaging has encountered a rapid development in recent years, thus the amount of pulmonary nodules can be discovered are on the raise, which means even tiny or minor changes in lung can be recorded by the CT images. This paper proposes a pulmonary nodule computer aided diagnosis (CAD) based on semi-supervised extreme learning machine(SS-ELM)...

BACKGROUND: Human pulmonary dirofilariasis is a rare zoonosis caused by the dog worm Dirofilaria spp., a parasite transmitted by mosquitos and resulting in peripheral lung nodules. The filarial nematode enters the subcutaneous tissue, travels to the right ventricle and dies causing a small pulmonary infarction that may embolize through the pulmonary vessels and may appear as a solitary nodule. These nodules are usually incidentally identified in asymptomatic patients undergoing chest imaging studies, and are generally interpreted to be malignant...

Nocardiosis is a rare infection caused by ubiquitous soil-born, acid-resistant, Gram-positive bacteria that can be life-threatening in immunocompromised patients. Originally usually diagnosed in HIV-positive patients, only few cases have been reported in patients on immunosuppressive therapy for inflammatory bowel disease or rheumatologic disorders. We present a case of a 32-year-old man who was treated with infliximab, prednisolone, and azathioprine for severe terminal ileitis. Although the clinical status improved under triple immunosuppressive therapy, weight loss, weakness, and fatigue persisted...

BACKGROUND: Pulmonary nodules are a common but difficult issue for physicians as most identified on imaging are benign but those identified early that are cancerous are potentially curable. Multiple diagnostic options are available, ranging from radiographic surveillance, minimally invasive biopsy (bronchoscopy or transthoracic biopsy) to more invasive surgical biopsy/resection. Each technique has differences in diagnostic yield and complication rates with no established gold standard...

BACKGROUND: Patients with Cushing's disease (CD) with hypercortisolism have an increased risk of opportunistic infection. However, most CD patients exposed to infections are diagnostic latency, leading to a poor prognosis. METHODS: Six patients in our hospital and an additional six patients in the literature were included in this study. Clinical information of CD patients with pulmonary Cryptococcus neoformans are reviewed. RESULTS: The average baseline total cortisol and ACTH in serum at 8 am of all the patients was 44...

Extrapulmonary heterotopic ossification appears similarly to pulmonary nodules on CXR, and is in the differential for pulmonary nodules. It occurs following the bone trauma, and in early stages appears similarly to tumors. Heterotopic ossification is diagnosed by its calcification pattern via MRI or ultrasound and managed conservatively unless symptoms develop.

RATIONALE: Pleomorphic adenoma, the most common tumor of the salivary glands, is usually benign. It is well known, however, that pleomorphic adenomas occasionally undergo malignant transformation to carcinoma ex pleomorphic adenoma and can metastasize. More rarely pleomorphic adenomas can metastasize without histological malignant transformation. We herein report an unusual case of pleomorphic adenoma with multiple metastases comprehensively demonstrated on F-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT)...

Lymphomatoid granulomatosis (LYG) is a rare lung disorder diagnosed by radiological imaging of multiple pulmonary nodules and occasionally induced by methotrexate (MTX) use. To date, the treatment of LYG has not been standardized. We herein report the case of a patient with grade 3 MTX-related LYG who presented a bulky lung mass. Importantly, the disease condition only improved after the discontinuation of MTX and remained stable for more than 1 year. Chest physicians should be aware that LYG can develop as a single lung mass and spontaneously regress, even without aggressive chemotherapy, following the cessation of MTX...

Large septic pulmonary embolus is a rare finding in right-sided endocarditis. The entity represents a challenging diagnosis due to its variable and nonspecific clinical and radiological presentation and similarities with other conditions. We present a case of a 41 year-old woman who developed a large main pulmonary artery embolus and bilateral cavitary lung nodules in the setting of severe sepsis. Pulmonary artery exploration and clot retrieval ultimately revealed a large septic embolus from Streptococcus mutans native pulmonary valve endocarditis...

Disseminated Rhodococcus equi infection was diagnosed in an Anglo-Nubian goat presenting for non-weight bearing lameness of the right pelvic limb. Radiographs showed a moth-eaten osteolytic lesion in the proximal tibia suggestive of an aggressive bone lesion. Two pulmonary nodules were also present on thoracic radiographs. Initial antemortem cytology of the tibial lesion was suggestive of Rhodococcosis and the goat was sent to necropsy. Necropsy and bacterial culture confirmed the diagnosis of disseminated R...
