Surprisingly, these measures were not associated with the predicted subscales, suggesting that these perceptual differences may not be present across the schizophrenia spectrum.Hyaline fibromatosis syndrome (HFS) is a rare, progressive, autosomal recessive disorder that presents with connective tissue deposition of amorphous hyaline material within the musculocutaneous tissue and/or visceral organs. HFS presents clinically in infancy or early childhood and can result in severe disability and life threatening complications. Given the rarity of the disorder, the imaging characteristics of HFS are seldom described in the literature. We describe a case of a 25-year-old patient presenting with bilateral knee pain, limited range of motion in her extremities, and lower extremity weakness with detailed MR imaging demonstrating the first case of multifocal intra-articular deposition of hyaline material within several joints.

Diagnosis of amiodarone lung toxicity on computerized tomography (CT) can be challenging especially in the presence of mass-like consolidation. Additional causes of mass-like consolidation including malignancy and pneumonia should be excluded, sometimes requiring tissue sampling.

Here we present a case of amiodarone lung toxicity, with diagnosis suspected based on patient's history of chronic cardiac disease, amiodarone treatment, and imaging characteristics. Evaluation with dual energy CT demonstrated high iodine content in the mass-like consolidation further supporting the diagnosis. Biopsy of the mass-like consolidation confirmed amiodarone toxicity.

Dual energy CT has potential utility in differentiating mass-like consolidation from other etiologies such as malignancy or pneumonia.

Infiltrative HCC can be a challenging diagnosis and it is associated with the worst overall survival among HCC patients. Infiltrative HCC is characterized by the spread of multiple minute nodules throughout the liver, without a dominant one, ultimately resulting into macrovascular invasion. On CT and MRI, infiltrative HCC appears as an ill-defined, large mass, with variable degree of enhancement, and satellite neoplastic nodules in up to 52% of patients. On MRI, it may show restriction on diffusion weighted imaging, hyperintensity on T2- and hypointensity on T1-weighted images, and, if hepatobiliary agent is used, hypointensity on hepatobiliary phase. Infiltrative HCC must be differentiated from other liver diseases, such as focal confluent fibrosis, steatosis, amyloidosis, vascular disorders of the liver, cholangiocarcinoma, and diffuse metastatic disease. In cirrhotic patients, the identification of vascular tumor invasion of the portal vein and its differentiation from bland thrombosis is of utmost importance for patient management. On contrast enhanced CT and MRI, portal vein tumor thrombosis appears as an enhancing thrombus within the portal vein, close to the main tumor and results into vein enlargement. The aim of this pictorial review is to show CT and MRI features that allow the diagnosis of infiltrative HCC and portal vein tumor thrombosis. A particular point of interest includes the tips and tricks for differential diagnosis with potential mimickers of infiltrative HCC.

We introduce a new sign on a Merchant view present in acute patellar tendon ruptures (APTR). We aim to determine the accuracy, sensitivity, and specificity of this new radiographic sign and measure the effect of a tutorial on these measures between trainees and non-trainees.

Lateral and Merchant radiographs (22 images) of knees with four conditions (patellar instability, APTR, quadriceps tendon rupture, and controls) were randomly shown to 50 trainees and non-trainees who were asked to make a diagnosis based on radiographs. A brief tutorial was administered describing the "Empty Merchant Sign" and the same 22 images were randomly shown after the tutorial. Accuracy, sensitivity, specificity, and positive predictive value were calculated between the two image types and the effect of tutorial on these measures was assessed.

After the tutorial 1. the "Empty Merchant Sign" had a higher specificity (100%) and positive predictive value (99%) compared to the lateral radiograph (81% and 64% respectively, P<0.001), 2. There was significant improvement (from 56% to 95.3%; P<0.001) in the accuracy of the Merchant view, making it as accurate as the lateral view (95.3% vs. 90.7%, respectively; P=0.113). There was no difference in the accuracy of the Merchant view between trainees (97.2%) and non-trainees (90.5%) (P=0.079).

The "Empty Merchant Sign" is a highly sensitive and specific diagnostic sign in cases of APTR. read more With very little training, physicians can identify this sign to diagnose APTRs on a Merchant view.

To compare the role of MR for assessment of extent of disease in women newly diagnosed with breast cancer imaged with digital mammography (DM) alone versus digital breast tomosynthesis (DBT).

Retrospective review was conducted of 401 consecutive breast MR exams (10/1/2013-7/31/2015) from women who underwent preoperative MR for newly diagnosed breast cancer by either DM or DBT, leaving 388 exams (201 DM and 187 DBT). MR detection of additional, otherwise occult, disease was stratified by modality, breast density, and background parenchymal enhancement. A true-positive finding was defined as malignancy in the ipsilateral-breast >2cm away from the index-lesion or in the contralateral breast.

50 additional malignancies were detected in 388 exams (12.9%), 37 ipsilateral and 13 contralateral. There was no difference in the MR detection of additional disease in women imaged by either DM versus DBT (p=0.53). In patients with DM, there was no significant difference in the rate of MR additional cancer detection in dense versus non-dense breasts (p=0.
