Nocardiosis is a rare cause of opportunistic infection post hematopoietic stem cell transplant (HSCT) occurring in about 0.3% of patients. The risk factors include delayed immune reconstitution, prolonged neutropenia, and graft-versus-host disease. The most common site of infection is the lung, followed by the brain and the skin. Concomitant pulmonary and central nervous system (CNS) nocardiosis is an extremely rare entity as presented in our case. We present the case of a 72-year-old male at 137 days post transplant presenting with complaints of headache and slurred speech...

BACKGROUND: Nonoperative management of midshaft clavicle fractures has resulted in widely disparate outcomes and there is growing evidence that clavicle shortening poses the risk of unsatisfactory functional outcomes due to shoulder weakness and nonunion. Unfortunately, the literature does not clearly demonstrate the superiority of one particular method for measuring clavicle shortening. The purpose of this study was to compare the accuracy of clavicle shortening measurements based on plain radiographs with those based on computed tomography (CT) reconstructed images of the clavicle...

To assess the doses delivered to pediatric patients during computed tomography (CT) examinations of the brain, chest, high-resolution lung and abdomen, and to establish diagnostic reference levels (DRLs) for various age groups in Korea. Dose survey was done to the 19 hospitals performing CT on children, addressing the scan parameters, volume CT dose index (CTDIvol) and dose length product (DLP). Per five age group (0, 1, 2-5, 6-10, 11-17 y of age), the proposed DRLs for brain, chest, high-resolution lung and abdomen CT are, respectively, in terms of CTDIvol: 18, 23, 26, 31, 36 mGy; 2, 3, 4, 6, 8 mGy; 2, 3, 4, 5, 7 mGy; 3, 4, 5, 6, 9 mGy; and in terms of DLP: 260, 350, 420, 500, 620 mGy•cm; 50, 80, 100, 170, 340 mGy•cm; 30, 40, 60, 90, 280 mGy•cm; 70, 80, 200, 300, 500 mGy•cm...

PURPOSE: Since intrathoracic goiters (IG), either cervico-mediastinal goiters (CMGs) or mediastinal nodules (MNs), can lead to sternotomies and/or evitable reoperations, their detection is mandatory before thyroid surgery. A systematic screening by CT scan or MRI is not conceivable because of their expensiveness. We tested if conventional chest radiography (CCR) could remain a good screening tool for IG before thyroid surgery. METHODS: In this retrospective study (2554 patients), CCR usefulness was evaluated in relation with patients' complaints, clinical examination, neck US, and anatomical and surgical findings...

BACKGROUND: Current data have shown that lung ultrasound (LUS) may be useful in the detection of interstitial lung disease (ILD) by the evaluation of B-lines, the sonographic marker of pulmonary interstitial syndrome. Nevertheless, no prospective study has compared LUS to chest X-ray (CXR) for ILD assessment, and there is no general agreement on the specific echographic diagnostic criteria for defining ILD. OBJECTIVES: The aims of this study were (1) to compare the accuracy of LUS and CXR in the detection of ILD using high-resolution CT (HRCT) as the gold standard and (2) to compare the accuracy of different echographic diagnostic criteria for ILD diagnosis...

Bone metastases resulting from a primary tumor invasion to the bone are common and cause significant morbidity in advanced cancer patients. Although the detection of bone metastases is often straightforward, it is difficult to identify their spread and track their changes, particularly in early stages. This paper presents a novel method that automatically finds the changes in appearance and the progress of bone metastases using longitudinal CT images. In contrast to previous methods based on nodule detection within a specific bone site in an individual CT scan, the approach in the present study is based on the subtraction between two registered CT volumes...

Congenital diaphragmatic hernia (CDH) is caused due to abnormal formation of the muscular parts of diaphragm. The incidence of CDH in common births ranges from 1/25000 to 1/30000. Pulmonary hypoplasia and pulmonary hypertension are factors that associate with the increase of mortality and morbidity due to CDH. We presented a 68-year-old Iranian woman with abdominal pain and tenderness in right upper quadrant who was diagnosed as having CDH. The disease was detected using chest X-ray and chest and abdomen sonography and confirmed with chest and abdomen CT scan with and without oral contrast...

Lung herniation (LH) is a rare clinical entity involving the protrusion of lung outside the thoracic cage. It has a variety of etiologies and clinical presentations, making diagnosis difficult. We present a case of a 20-year-old male who reported pleuritic pain after falling from a skateboard. Evaluation through computed tomography (CT) scanning of the chest revealed an anterior lung hernia associated with rib fractures. This case emphasizes the need for clinicians to include lung herniation in the differential diagnosis of patients with trauma and inexplicable or persistent pulmonary issues...

PURPOSE: Traditionally, determination of total lung capacity (TLC) by plethysmography (TLCpleth) has been important in the diagnosis of lung diseases. Alternatively, data acquired from computerized tomography (CT) can be utilized to calculate a measure of TLC (TLCCT). The clinical utility of TLCCT is not certain. We sought to determine, in a clinical setting, whether TLCCT correlates with TLCpleth across a range of lung diseases and scanning techniques. In addition, we determined whether TLCCT affects the interpretation of pulmonary function tests...
