Osteochondroma is the most common benign bone tumor but it rarely arises from the scapula. Scapulothoracic bursitis is quite rare and osteochondroma is one of the unusual causes of this condition. Synovial chondromatosis may occur extremely uncommonly in this bursa. We reported an unusual case of scapulothoracic bursitis with synovial chondromatosis which is caused by osteochondroma. To the best of our knowledge, there is no defined chondromatosis in the scapulothoracic bursa secondary to scapular osteochondroma in the literature...

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...

Cystic intestinal pneumatosis (CIP) is the presence of gas bubbles inside the wall of the intestine. In literature it has been reported to be associated with a variety of clinical conditions such as: superior mesenteric ischemia, intestinal perforation, bowel necrosis, infections which can cause mucosal alterations and therefore increasing its permeability, necrotizing enterocolitis in babies, trauma, intestinal obstruction, autoimmune and pulmonary pathologies. Its presence is usually documented by radiological techniques such as abdominal X-ray, CT scan and endoscopy and are usually characterized by the typical pattern of gas bubbles in the wall of the intestine...

Backgrounds: Bronchiectasis (BE) with nodules on chest computed tomography (CT) is one of the radiological findings of nontuberculous mycobacteria (NTM) lung disease. However, the NTM lung disease is not diagnosed in some patients who undergo bronchoscopy, though their radiological findings show BE with nodules. We need the indicator to distinguish the patients who would not be given the diagnosis of NTM lung disease with bronchoscopy. Methods: We retrospectively reviewed the records of the patients who underwent bronchoscopy from January 2010 to July 2013 at our hospital because sputum test had not yielded the diagnosis of NTM lung disease or the patients had been unable to produce sputum, though their chest CT had shown BE with nodules...

The aim of the present study was to investigate the computed tomography (CT) manifestations of Wegener granulomatosis (WG) in the chest and potential reasons for misdiagnosis. Conventional CT scans and clinical data of 45 patients with WG were retrospectively analyzed. Patients typically presented with multiple system involvement, primarily in the upper and lower respiratory tract. The incidence of thoracic involvement was 75.56% (34/45). Radiographic features were varied between cases in the present study, with the most common features being numerous cavitary nodules and masses in the lungs...

We present a case of a 76 year-old, non-smoking Honduran female who was referred to our clinic for years of persistent dry cough. Cardiac evaluation was unremarkable. She denied symptoms of heartburn, allergic rhinitis, and there was no personal or family history of asthma. Her physical exam demonstrated wheezing over the right mid-posterior chest. Spirometry was within normal limits. CT-imaging of the chest demonstrated right middle lobe bronchus and lingular segmental bronchus narrowing with bibasilar atelectasis and mild interlobular septal thickening with prominent mediastinal adenopathy...

The purpose of this case presentation is to discuss right upper quadrant pain as an atypical presenting symptom in pulmonary infarction and review the typical computed tomography (CT) imaging features of pulmonary infarction to improve diagnostic accuracy. Pulmonary infarction results from occlusion of distal arterial vasculature within the lung parenchyma leading to ischemia, hemorrhage, and ultimately necrosis. Patients with lung infarction typically present with pleuritic chest pain and may have associated signs or symptoms of pulmonary thromboembolism or deep vein thrombosis...

PURPOSE: Evaluation of noise texture information in CT images is important for assessing image quality. Noise texture is often quantified by the noise power spectrum (NPS), which requires numerous image realizations to estimate. This study evaluated fractal dimension for quantifying noise texture as a scalar metric that can potentially be estimated using one image realization. METHODS: The American College of Radiology CT accreditation phantom (ACR) was scanned on a clinical scanner (Discovery CT750, GE Healthcare) at 120 kV and 25 mAs and 90 mAs...

BACKGROUND: Spontaneous esophageal rupture, also known as Boerhaave syndrome, is a very serious life-threatening benign disease of the gastrointestinal tract. It is typically caused by vomiting after heavy eating and drinking. However, in our patient, because of a combination of hypopharyngeal cancer with stenosis and chemoradiotherapy (CRT), which caused chemotherapy-induced vomiting, radiotherapy-induced edema, relaxation failure, and delayed reflexes; resistance to the release of increased pressure due to vomiting was exacerbated, thus leading to Boerhaave syndrome...
