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...

This report presents a rare case involving a patient with a giant leiomyoma originating from the mediastinal pleura. The patient underwent a medical examination, and chest radiography revealed a giant tumor. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a well demarcated, heterogeneous mass which seemed to originate from the posterior mediastinum. Positron emission tomography (PET) showed the uptake of this tumor with a standardized uptake value of 4.9. We suspected that this tumor was a solitary fibrous tumor, and the patient underwent a surgical resection...

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...

The goal of this study is to evaluate whether NT-proBNP plasma levels may help as a screening biomarker for monitoring right ventricular dilatation, pulmonary regurgitation and the onset of heart failure in patients with repaired Tetralogy of Fallot. Our single-centre observational prospective study involved 43 patients (15.1 years, SD = 8) with corrected Tetralogy of Fallot. Data collection included: clinical parameters (electrocardiogram, chest X-ray, NYHA scale, time since last surgery), biochemistry (NT-proBNP levels) and MRI values (ventricular volumetry, pulmonary flow assessment)...

The ability of lung imaging to phenotype patients, determine prognosis, and to predict response to treatments is expanding in clinical and translational research. The purpose of this perspective is to describe current imaging modalities that may be useful clinical tools in asthma and other lung disorders and to explore some of the new developments in imaging modalities of the lung. These imaging modalities include chest radiography (CXR), computed tomography (CT), lung magnetic resonance imaging (MRI), electrical impedance tomography (EIT), bronchoscopy, and others...

BACKGROUND: Neurosarcoidosis is a rare variant of sarcoidosis and is only described in small cohort studies. We define clinical features, treatment and outcome of patients with neurosarcoidosis over the last 35 years. METHODS: We performed a systematic review and meta-analysis of studies on neurosarcoidosis published between 1980 and 2016. Studies were included if they reported at least 5 cases. Studies describing one specific neurological presentation were excluded...

A 63-year-old female with a history of invasive ductal breast carcinoma presented to the emergency department with symptoms characteristic of myocardial infarction. Electrocardiography showed sinus tachycardia and ST elevations in leads II, III, and aVF, consistent with inferior wall myocardial infarction. A computed tomography (CT) scan of the chest, abdomen, and pelvis with intravenous contrast demonstrated widespread intrathoracic metastatic disease. Cardiac magnetic resonance imaging (MRI) with contrast revealed obstruction of the left ventricular (LV) outflow tract by an LV mass...

Stage I breast carcinoma is classified when an invasive breast carcinoma is ≤2 cm in diameter (T1), with no regional (axillary) lymph node metastases (N0) and no distant metastases (M0). The most common sites for metastases from breast cancer are the skeleton, lung, liver, and brain. In general, women and health care professionals prefer intensive screening and surveillance after a diagnosis of breast cancer. Screening protocols include conventional imaging such as chest radiography, bone scan, ultrasound of the liver, and MRI of brain...

PURPOSE: The purpose of this study was to evaluate the effect of defective positron emission tomography (PET) detectors on clinical PET image quality in simultaneous PET/magnetic resonance imaging (MRI) for both time-of-flight (TOF) and non-TOF reconstructed images. PROCEDURES: A total of six patients with various malignant tumors were included and underwent a 2-deoxy-2-[(18)F]fluoro-D-glucose PET scan in a fully functional simultaneous TOF PET/MRI. TOF and non-TOF PET images were reconstructed before and after simulating defective detector units...

We assessed whether magnetic resonance imaging (MRI) is applicable for diagnosing pneumonia among adult outpatients with lower respiratory tract infection.Patients were recruited prospectively when they had symptoms for ≤7 days and fever ≥37.8 °C. The patients underwent high-resolution computed tomography (HRCT), MRI and chest radiography, which were repeated 1 month later if necessary, to verify pneumonia. The duration of MRI examination was 3-4 min.Among 77 patients, HRCT, MRI and radiography identified 32 (41...

Tuberous sclerosis is characterized by typical skin and clinical manifestations with predilection to neoplasia. We describe the case of a 42-year old female who presented with a mass and pain in right lumbar region with constitutional symptoms and generalized body aches since last one year. She had adenoma sebaceum, subungual fibromas and hepatomegaly. CT chest, abdomen and MRI revealed mass in the right renal fossa with wide spread extensions in the abdomen, left renal angiomyolipomas (AMLs) and intracerebral lesions...

BACKGROUND: Surgery for lung cancer invading the spine remains challenging associated with high morbidity and mortality. However, recent advances in surgical techniques as well as in perioperative care may improve outcomes of lung cancer surgery with vertebrectomy. We describe our surgical approach and assess the outcome lung cancer invading the spine. METHODS: We retrospectively reviewed our recent experiences of lung cancer with vertebral invasion, in which we have performed total or partial vertebrectomy from January 2011 through April 2015...

Metastasis to secondary sites such as the lung, liver and bone is a traumatic event with a mortality rate of approximately 90% (1). Of these sites, the lung is the most difficult to assess using intravital optical imaging due to its enclosed position within the body, delicate nature and vital role in sustaining proper physiology. While clinical modalities (positron emission tomography (PET), magnetic resonance imaging (MRI) and computed tomography (CT)) are capable of providing noninvasive images of this tissue, they lack the resolution necessary to visualize the earliest seeding events, with a single pixel consisting of nearly a thousand cells...

A known case of primary Sjogren's syndrome with chronic kidney disease presented with respiratory symptoms and subsequent altered sensorium. Chest imaging suggested cavitating lung lesions in both the lungs. Serum c-ANCA was positive without any upper respiratory tract involvement or active urinary sediments. Treatment with appropriate anti-microbials produced no improvement in the respiratory or neurological parameters. MRI brain revealed tell-tale signs of CNS vascultis. A diagnosis of GPA was made as per European Medical Agency algorithm and the patient was started on immune-suppressants to which there was dramatic response...

Post-pericardiotomy syndrome (PPS) occurs in a subgroup of patients who have undergone cardiothoracic surgery and is characterized by fever, pleuritic pain, pleural effusion, and pericardial effusion. It is associated with significant morbidity, and the leading complications include tamponade and constrictive pericarditis. Epidemiologic studies have found that PPS often occurs among younger patients; however, there is a lack of comprehensive risk stratification. It is therefore important to be able to identify patients who are at high risk for developing this disease...
