BACKGROUND AND RATIONALE: Respiratory system involvement in scrub typhus is seen in 20-72% of patients. In endemic areas, good understanding and familiarity with the various radiologic findings of scrub typhus are essential in identifying pulmonary complications. MATERIALS AND METHODS: Patients admitted to a tertiary care center with scrub typhus between October 2012 and September 2013 and had a chest X ray done were included in the analysis. Details and radiographic findings were noted and factors associated with abnormal X-rays were analyzed...

Hereditary multiple exostosis (HME) is an autosomal dominant disorder characterized by two or more benign growing, cartilage capped tumors of long bones called osteochondromas. If abnormal growth and clinical symptoms of osteochondromas newly appear in adults, malignant transformation of the usually benign growing tumors should be suspected and diagnostic testing should be initiated. Against the background of hypothesized higher malignant transformation of osteochondromas into chondrosarcoma in individuals with shoulder exostoses, we report a case of bilateral scapulothoracic osteochondromas in a patient suffering from HME...

Lobar torsion is well documented after pneumonectomy, but is very rare after lung transplant. To the best of our knowledge, this is the twelfth reported case of lobar torsion after lung transplant. In our case, bronchoscopies and chest radiographs were inconclusive; however, CT scan clearly demonstrated findings consistent with right middle lobe torsion. We review the literature and discuss the epidemiology, clinical presentation, imaging features, and treatment considerations for this condition. We also propose that if a clinical picture could be secondary to torsion and bronchoscopies and chest x ray are inconclusive that a CT scan should be obtained as soon as possible since early recognition increases the likelihood of being able to successfully detorse the lung and avoid lobectomy...

Pulmonary sclerosing hemangioma is an uncommon benign tumor of the lung; however, on rare occasions it can arise from the pulmonary hilar region. Herein, we report a 53-year-old female patient who presented with a round opacity in the right upper lung field on a radiograph. Chest computed tomography scanning revealed a 3.1 cm mass in the right pulmonary hilum. Thoracoscopic tumor excision was subsequently performed. On pathohistologic study, the tumor was well defined and composed of round stromal cells and surface cells arranged in a papillary, sclerotic, solid, and hemorrhagic pattern...

A 37-year-old man presented at our hospital. Pathological examination of a right orchiectomy specimen, radiographic examination, and tumor marker profile resulted in a diagnosis of retroperitoneal nonseminomatous germ cell tumor (intermediate risk according to IGCC classification). Laboratory testing revealed mild elevation of low density lipoprotein cholesterol. Induction chemotherapy with bleomycin, etoposide and cisplatin (BEP) was started, but he complained of chest pain on day 10 of the second cycle of BEP...

A 39-year-old man, born in India but resident in the UK for 10 years, was travelling in America when he became feverish with an altered mentation. He reported a 10-day history of fever, photophobia, headache and fatigue. His medical history included hypothyroidism and migraine. He was a non-smoker, did not consume alcohol and denied a history of drug use. He was transferred to the emergency department. Laboratory investigations confirmed hyponatraemia (sodium 128 mmol/L). A chest radiograph confirmed no focal consolidation...

Nonosseous uptake in Tc-hydroxymethylene bone scintigraphy should always be evaluated for any possibility of pathological changes. We share interesting images of a 60-year-old woman initially investigated for suspected osteomyelitis of the left femur but found to have an extraosseous uptake in the right hemithorax on bone scintigraphy. Plain chest radiograph followed by contrast-enhanced CT of the thorax revealed the presence of a lung mass in the right lower lobe with no lymphadenopathy. CT-guided biopsy yielded fibrocollagenous tissue, partly lined by benign pneumocytes...

BACKGROUND: Single-lead for implantable cardioverter-defibrillator (ICD) with floating atrial sensing dipole is a new diagnostic tool with the potential advantage in terms of arrhythmia discrimination. We sought to determine whether right heart size and dipole position influence atrial sensing. METHODS: Atrial sensing amplitude (AS) was measured during implantation (PP, periprocedural), predischarge (IHFU, in-hospital follow-up) and 3-6 months after the procedure (AFU, ambulatory follow-up)...

BACKGROUND: Tuberculosis elimination in countries with a low incidence of the disease necessitates multiple interventions, including innovations in migrant screening. We examined a cohort of migrants screened for tuberculosis before entry to England, Wales, and Northern Ireland and tracked the development of disease in this group after arrival. METHODS: As part of a pilot pre-entry screening programme for tuberculosis in 15 countries with a high incidence of the disease, the International Organization for Migration screened all applicants for UK visas aged 11 years or older who intended to stay for more than 6 months...

Multifocal osteomyelitis and synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome constitute a spectrum of disease that includes inflammatory bone lesions and dermatologic findings. Radiographic features resemble those of the spondyloarthropathies with anterior chest wall involvement. Early radiographic findings are osteodestructive with lytic lesions. Bone scintigraphy of the sternoclavicular region classically yields a 'bull's head' pattern of radionuclide uptake. Magnetic resonance imaging (MRI) can demonstrate corner lesions of vertebral bodies...

RATIONALE: Automated analysis of computed tomographic (CT) lung images for epidemiologic nand genetic association studies is increasingly common, but little is known about the utility of visual versus semi-automated emphysema and airway assessments for genetic association studies. OBJECTIVES: Assess the relative utility of visual versus semi-automated emphysema and airway assessments for genetic association studies. METHODS: A standardized inspection protocol was used to visually assess chest CTs for 1540 non-Hispanic white subjects within the COPDGene Study for the presence and severity of radiographic features representing airway wall thickness and emphysema...

Ambient dose equivalent H (*)(10) is an operational quantity recommended by the IAEA to establish dose constraints in area monitoring for external radiation. The direct measurement of H (*)(10) is not common due to the complexity in the calibration procedures of radiation monitors involving the use of expanded and aligned radiation fields. Therefore, conversion coefficients are used to assess H (*)(10) from the physical quantity air-kerma. Conversion coefficients published by international commissions, ICRU and ICRP, present a correlation with the radiation beam quality...

We report a case of pulmonary cryptococcoma, in an adult with recently detected diabetes, mimicking as lung cancer. A 45-year-old gentleman with past history of pulmonary tuberculosis presented with fever, cough with expectoration, pleuritic chest pain and hemoptysis. Chest radiograph and computed tomography revealed right lower lobe mass which significantly enhanced on contrast administration. Ultrasound guided biopsy was done which on histopathological examination showed non-necrotizing granulomas with narrow-based budding yeast cells suggestive of cryptococcosis...

The study aimed to determine if computer vision techniques rooted in deep learning can use a small set of radiographs to perform clinically relevant image classification with high fidelity. One thousand eight hundred eighty-five chest radiographs on 909 patients obtained between January 2013 and July 2015 at our institution were retrieved and anonymized. The source images were manually annotated as frontal or lateral and randomly divided into training, validation, and test sets. Training and validation sets were augmented to over 150,000 images using standard image manipulations...

BACKGROUND: Current Canadian guidelines suggest that neonatal Bacille Calmette-Guérin (BCG) vaccination does not result in false-positive tuberculosis (TB) skin tests, despite a growing body of evidence that interferon-γ release assays may be a more specific alternative in identifying latent tuberculosis infections in vaccinated populations. We set out to evaluate the relationship between TB skin tests and interferon-γ release assays in patients who previously received neonatal BCG vaccine...
