A 31-year old woman with persistent fever for 6 weeks and unresponsive to antibiotic therapy came for rheumatologic investigation. After computed tomography (CT) studies of her neck, thorax and abdomen revealed bilateral cervical, axillary and retroperitoneal lymph node enlargements, histopathologic evaluation of the resected nodes showed features of histiocytic necrotizing lymphadenopathy suggestive of Kikuchi-Fujimoto's lymphadenopathy. Kikuchi-Fujimoto Disease (KFD) involving the retroperitoneal nodes is extremely unusual and even more challenging to diagnose when there are no early signs of extranodal involvement or abdominopelvic pain...

The purpose of this study is to investigate truncated axial computed tomography (CT) images in the clinical environment and to produce correction factors for abdomen, thoracic and head regions based on clinical data, in order to accurately predict the water-equivalent diameter (DW) and size-specific dose estimate (SSDE). We investigated axial images of 75 patients who underwent CT examinations. Truncated axial images were characterized by the truncation percentage (TP). Correction factors were calculated by using the value of DW for a certain TP (truncated image) divided by the value of DW for TP = 0% (the non-truncated image)...

We describe a case of 52-year-old man who presented with an episode of tonic-clonic seizures. He had right ocular melanoma 23 years ago with subsequent enucleation which was the standard treatment at that time. CT scans of the brain and of the thorax-abdomen-pelvis revealed widespread metastatic lesions in the brain, lung and liver. Further investigations including bronchoscopy with cytopathology uncovered that the metastatic disease was a recurrence of ocular melanoma. He received palliative radiotherapy and died 6 months later...

Both in radiography and computed tomography (CT), recently emerged energy-resolved x-ray photon counting detectors enable the identification and quantification of individual materials comprising the inspected object. However, the approaches used for these operations require highly accurate x-ray images. The accuracy of the images is severely compromised by the presence of scattered radiation, which leads to a loss of spatial contrast and, more importantly, a bias in radiographic material imaging and artefacts in CT...

Congenital diaphragmatic hernia (CDH) usually presents in infancy with respiratory failure requiring urgent surgical correction. Mortality in this group of patients remains poor and persistent pulmonary hypertension is a significant contributor. It is therefore rare for patients to reach adulthood undiagnosed. CDH is often identified incidentally in adults but when symptoms arise, they relate to the organ involved, and include gastrointestinal symptoms of dyspepsia and obstruction, as well as respiratory complaints such as dyspnoea...

AIMS: Decision-making in management of clavicle fractures is often based on the degree of displacement and shortening present on plain radiographs. We aimed to evaluate whether plain radiographs provide an accurate representation of the true displacement present, which can be difficult to image in orthogonal planes. METHODS: Consecutive high-energy trauma patients with midshaft clavicular fractures requiring further CT imaging of the thorax/abdomen for other associated injuries between 2009 and 2012 were evaluated...

The use of parameters water equivalent diameter (D W ) and size-specific dose estimate (SSDE) are becoming increasingly established as a recognised method to relate patient dose from a CT examination to the dose indicator volume CT dose index (CTDIVOL). However, the role of the attenuation due to the patient table in these estimations requires careful consideration and is the subject of this study. The aim of this study is to investigate the impact of a minimal part of the patient table when calculating the D W and SSDE...

INTRODUCTION: In spite of increasing quality of emergency room (ER) assessment in trauma patients and improved accuracy of modern multislice computed tomography (MSCT), the number of potentially missed diagnoses is still controversial. The aim of this study was to compare the initial findings of ER assessment and MSCT to the findings during autopsy in trauma patients not surviving the first 48 h after admission. We hypothesized that autopsy was more accurate than MSCT in diagnosing potentially fatal diagnoses...

Endobronchial ultrasound (EBUS) is a technique for the detection of mediastinal abnormalities. A total of 548 EBUS procedures were performed for various indications, and in four cases (0.7%), filling defects in central pulmonary arteries were demonstrated fortuitously during the procedure. Subsequently, all patients underwent contrast-enhanced CT of the thorax to confirm the diagnosis of pulmonary thromboembolism (PTE). In three of the four cases, there was a concomitant lung cancer. PTE can be incidentally detected during EBUS; therefore, pulmonary arteries should be examined carefully during EBUS in all patients, particularly in patients with suspected or proven malignancy...

PURPOSE: To develop a clinically feasible method for dose calculations on cone beam CT (CBCT) images of two different vendors, and to determine the accuracy of these dose calculations for lung cancer patients. METHODS: Lung cancer patients with CBCT imaging (n = 10 for Elekta, n = 6 for Varian) and a repeated planning CT scan on the same day were selected. For CBCT dose calculations, an adapted Hounsfield units-to-mass density table (HU table) was used which was obtained by comparing CT values of corresponding points on the CBCT and the repeated planning CT scan...

OBJECTIVES: Haemoptysis occurring in a Behçet's syndrome (BS) patient with pulmonary artery involvement (PAI) during follow-up is usually regarded as PAI relapse. However, bronchial artery enlargement (BAE) may be the source of haemoptysis in some patients. METHODS: A chart review at the end of December 2014 revealed 118 patients with PAI in our centre since 1979. Nine (all men) had recurrent haemoptysis during follow-up which could not be explained with relapse of PAI...

BACKGROUND Lymphangioma is an atypical non-malignant, lymphatic lesion that is congenital in origin. Lymphangioma is most frequently observed in the head and neck, but can occur at any location in the body. About 65% of lymphangiomas are apparent at birth, while 80-90% are diagnosed by two years of age. Occurrence in adults is rare, as evidenced by less than 100 cases of adult lymphangiomas reported in the literature. CASE REPORT A 36-year-old Indian woman with a medical history of recurrent pleural effusions presented with chief complaints of dyspnea on exertion for one year and a low-grade fever for one month...
