#1
Kirryn Williams, Graham Simpson
This case report describes a case of thoracic splenosis. Splenosis is often interpreted as malignancy on initial imaging. Case reports described in the literature reveal that diagnosis is most often confirmed with invasive investigations. A 99 m technetium-labelled sulphur colloid scan when used with single photon emission computed tomography/computed tomography (SPECT/CT) is highly specific for splenic tissue and more readily available and time efficient than other modalities used for this purpose. Awareness of this may prevent unnecessary or dangerous invasive diagnostic procedures...

Fibrodyplasia ossificans progressiva (FOP) is an ultra-rare genetic condition of heterotopic ossification (HO) that results in progressive loss of joint function, ultimately rendering movement impossible. Death is most commonly the result of thoracic insufficiency syndrome, or complications related to recurrent respiratory infections. There are no current treatments for FOP, but early and emerging clinical trials offer hope for this devastating disease. With the recent reporting of a comprehensive global natural history study, scales to assess joint dysfunction, and a more accurate prediction of joint survival, it is now possible to construct a conceptual framework for the clinical staging of FOP...

BACKGROUND: It is generally recognized that the main thoracic curve Cobb angle threshold for surgical correction is approximately 50 degrees in patients with adolescent idiopathic scoliosis (AIS). Although AIS with a Cobb angle of <50 degrees is sometimes treated surgically to improve cosmesis, the precise outcomes are unclear. This study analyzed the postoperative results for AIS with a main thoracic curve of 50 degrees. METHODS: Thirty-nine consecutive patients with Lenke type 1-2 curves underwent posterior spinal fusion for AIS...

OBJECTIVE: We evaluated images of patients undergoing a thoracic endovascular aortic repair procedure using two reference points as a means for differentiating stent graft migration from aortic elongation. Conventional standards define migration of a stent graft as an absolute change in the distance from the distal graft ring to a distal landmark ≥10 mm compared with a baseline measurement. Aortic elongation occurs over time in both healthy individuals and patients with aortic disease...

BACKGROUND: Retrograde false lumen perfusion is a common mode of failure after stent grafting chronic aortic dissection. Open fenestration during the first-stage elephant trunk (ET) creates a landing zone for second-stage endovascular ET completion in patients with a false lumen aneurysm. Our objectives were to assess long-term safety and durability of this technique. METHODS: From 2007 to 2014, 56 patients with thoracoabdominal dissection and aneurysm underwent stage 1 ET and open fenestration...

A 39-year-old man with syncope and persistent dizziness was sent to stroke emergency. Patient's diffusion magnetic resonance imaging of brain showed acute ischemia in right cerebella and right occipital lobe, thus intravenous recombinant tissue plasminogen activator was given to him. However, the patient behaved rather restless with repeated complaint of back and thoracic pain. Further thorax computed tomography angiography confirmed that the underlying cause turned out to be aortic dissection.

Blunt injuries to the chest wall are an important chapter on emergency room (ER) departments, being the third most common injuries in trauma patients which ominous complications could appear. This article describes different types of traumatic events affecting the chest wall, which maybe misdiagnosed with conventional X-ray. Special emphasis has been done in computed tomography (CT) and multidetector CT (MDCT) imaging. This technique is considered the "gold-standard" for those traumatic patients, due to its fast acquisition covering the whole area of interest in axial plane, reconstructing multiplanar (2D, 3D) volume-rendered images with a superb quality and angiographic CT capabilities for evaluating vascular damage...

BACKGROUND: Senior surgical residents are of paramount importance in directing further therapeutic modalities based on their interpretation of critical diagnostic imaging. We propose that senior surgical residents are proficient with interpreting radiologic imaging studies in the trauma patient. METHODS: A prospective cohort study was performed comparing surgery resident interpretations of computerized tomography (CT) scans of the head, maxillofacial bones, spine (cervical, thoracic, lumbar), chest, abdomen, pelvis, and chest X-rays versus final radiologists' reports at a level II trauma center from September 2014 to May 2015...

BACKGROUND: Despite increases in imaging guidelines for other body-regions during initial trauma assessment and the demonstrated utility of chest radiographs (CXR), guidelines for use of thoracic computed-tomography (TCT) are lacking. We hypothesized that TCT utilization had not decreased relative to other protocolized CTs, and mechanism and CXR could together predict significant injury independent of TCT. METHODS: We performed a retrospective review of blunt trauma patients ≤18 y...

BACKGROUND: Complex and reverse flow in the aorta has been implicated in aneurysm development and stroke via retrograde embolization. PURPOSE: To evaluate global and regional differences between standard 2D plane-based and volumetric voxel-based quantification of regional forward/reverse flow, and reverse flow fraction (RFF) in the aorta. STUDY TYPE: Retrospective. SUBJECTS: In all, 35 subjects: 10 healthy controls (age: 57 ± 7 years, nine male), nine patients without aortic valve regurgitation (AR) (age: 63 ± 10 years, seven male), six patients with mild AR (age: 66 ± 6 years, five male), and 10 with moderate or severe AR (age: 60 ± 16 years, eight male)...

The aim was to examine the effects of recumbency and anaesthesia on distribution of ventilation in beagle dogs using Electrical Impedance Tomography (EIT). Nine healthy beagle dogs, aging 3.7±1.7 (mean±SD) years and weighing 16.3±1.6 kg, received a series of treatments in a fixed order on a single occasion. Conscious dogs were positioned in right lateral recumbency (RLR) and equipped with 32 EIT electrodes around the thorax. Following five minutes of equilibration, two minutes of EIT recordings were made in each recumbency in the following order: RLR, dorsal (DR), left (LLR) and sternal (SR)...

Objectives Non-chylous lymphorrhagic pleural effusions are transudative effusions with a predominance of lymphocytes; however, they do not contain chylomicrons and therefore do not have the classical milky aspect of true chylous effusion. This type of effusion has been anecdotally associated with cardiac diseases in cats, but studies are lacking. The aim of this study was to investigate the association between this type of effusion and the primary disease. Methods In this study, feline non-chylous lymphorrhagic pleural effusions were retrospectively selected from the database of the authors' institutions over a 3 year period...

Lung diseases are increasing in prevalence and overall burden worldwide. To stem the tide, more and more national and international guidelines are recommending the use of various diagnostic algorithms that are disease specific. There is growing consensus among the respiratory community that although patient histories and lung function testing are the minimum required for clinical examinations, these tests alone are not sufficient for disease characterization. Therefore, the use of computed tomography (CT) imaging is increasing used in clinical decision making for lung diseases...
