Hypersensitivity pneumonitis secondary to foam exposure in mattress and pillows.

Fibrotic hypersensitivity pneumonitis (HP) has a poor prognosis when no antigen is identified, which occurs in many cases. We present a case of HP due to foam exposure in bedding, an unrecognised cause of HP. A woman was referred for dyspnoea and cough.

Adjusting Atrial Size Parameters for Body Surface Area: Does it Affect the Association With Pulmonary Embolism-related Adverse Events?

Purpose: Small left atrial (LA) volume was recently reported to be one of the best predictors of acute pulmonary embolism (PE)-related adverse events (AE). There is currently no data available regarding the impact that body surface area (BSA)-indexing of atrial measurements has on the association with PE-related adverse events. Our aim is to assess the impact of indexing atrial measurements to BSA on the association between computed tomography (CT) atrial measurements and AE.

Non-ECG-gated cardiac CT angiography in acute stroke is feasible and detects sources of embolism.

Background: A significant portion of cryptogenic stroke is hypothesized to be secondary to cardiac embolism. However, transthoracic echocardiogram is usually delayed after stroke, and more detailed cardiac imaging is not routinely done.

Aims: This study aimed to determine whether non-ECG-gated cardiac CT angiography (cCTA) during hyperacute stroke would provide diagnostic quality images and act as an adjunct modality of cardiac imaging to detect sources of emboli.

Evidence for Left Atrial Volume Being an Indicator of Adverse Events in Patients With Acute Pulmonary Embolism: Retrospective Case-control Pilot Study.

Purpose: To assess the association between computed tomography pulmonary angiography (CTPA) atrial measurements and both 30-day pulmonary embolism (PE)-related adverse events and mortality, and non-PE-related mortality, and to identify the best predictors of these outcomes by comparing atrial measurements and widely used clinical and imaging variables.

Patients And Methods: Retrospective single-center pilot study. Acute PE patients diagnosed on CTPA who also had a transthoracic echocardiogram, electrocardiogram, and troponin T were included.

Generalized lymphatic anomalies and review of the current management landscape: a case report and review of the literature.

Background: Generalized lymphatic anomaly previously known as diffuse systemic lymphangiomatosis is a rare multisystem congenital disease arising from the lymphatic system, and it is characterized by abnormal proliferation of the lymphatic channels in osseous and extraosseous tissues. It typically affects children or young adults. Although it is benign, it can be misdiagnosed as malignancy because of its diffuse and debilitating nature depending on the site of involvement.

Risk assessment of acute pulmonary embolism utilizing coronary artery calcifications in patients that have undergone CT pulmonary angiography and transthoracic echocardiography.

Objective: To evaluate the relation of coronary artery calcifications (CAC) on non-ECG-gated CT pulmonary angiography (CTPA) with short-term mortality in patients with acute pulmonary embolism (PE).

Methods: We retrospectively included all in-patients between May 2007 and December 2014 with an ICD-9 code for acute PE and CTPA and transthoracic echocardiography available. CAC was qualitatively graded as absent, mild, moderate, or severe.

Multimodality Assessment of Right Ventricular Strain in Patients With Acute Pulmonary Embolism.

Optimal risk stratification is essential in managing patients with an acute pulmonary embolism (PE). There are limited data evaluating the potential additive value of various methods of evaluation of right ventricular (RV) strain in PE. We retrospectively evaluated RV strain by computed tomography (CT), transthoracic echocardiography (TTE), electrocardiography (ECG), and troponin levels in consecutive hospitalized patients with acute PE (May 2007 to December 2014).

Inter-rater agreement in the characterization of cystic renal lesions on contrast-enhanced MRI.

Purpose: To evaluate inter-observer agreement of MRI features and classification of cystic renal masses among radiologist and radiology trainees.

Methods: Four readers (two radiologists and two radiology trainees) retrospectively reviewed 100 cystic renal lesions on gadolinium enhanced MRI and assigned each a Bosniak classification (1, 2, 2F, 3, and 4). Lesions were also assessed on their individual features including size, presence of nodules, septations, and enhancement.
