Walled-off necrosis (WON) is a well-known delayed local complication of acute necrotizing pancreatitis. Occasionally, WON may spontaneously rupture into the gastrointestinal tract or peritoneal cavity. However, erosion of a WON to a systemic vein has not been reported in literature so far. We report an unusual case of a 63-year-old male with acute necrotizing pancreatitis in whom WON was eroding into the inferior vena cava resulting in its thrombosis. Our patient also had a bunch of other well-described complications of pancreatitis including splanchnic venous thrombosis...

Mentor-mentee relationships within radiology residencies can add significant value to a resident's overall experience. Studies demonstrate that mentorship programs can increase satisfaction for residents and faculty alike by reducing stress, easing career related decisions, increasing involvement with research, improving teaching and communication skills, and finally increasing leadership roles. In a survey of radiology program directors, 85% of program directors find such a program beneficial but only 57% have a formal program in place...

PURPOSE: A low cost, reproducible radiographic method of diagnosing congenital lumbar spinal stenosis (CLSS) is lacking. We hypothesized that the Cobb angle for lumbar lordosis would be smaller in patients with CLSS, based on observations in our spine clinic patient population. Here, we compared lumbar lordosis Cobb angles with the radiographic ratio method in patients with normal spine imaging, degenerative spinal stenosis, and with CLSS. MATERIALS AND METHODS: Orthopedic surgeons categorized patients with low back pain as "Normal," "Degenerative spinal stenosis," and "CLSS" based on clinical presentation and findings on lumbar magnetic resonance imaging...

Currently, there are no clear indications or guidelines for performing breast magnetic resonance imaging (MRI) in male patients diagnosed with primary breast cancer. The literature is also very limited on the usage of breast MRI in male patients. Although it is not common or recommended as a routine clinical practice to perform breast MRI in male patients even in the setting of a diagnosis of breast cancer, there are few instances where MRI may help clinicians and surgeons. With a comprehensive review of cases that was performed at our institution over the last 10 years, the readers may achieve better understanding of when it may be helpful to perform breast MRI in male patients...

PURPOSE: To assess the effect on reader performance of an interactive case-based online tutorial for prostate magnetic resonance imaging (MRI) interpretation using Prostate Imaging and Reporting Data System (PI-RADS). METHODS: An educational website was developed incorporating scrollable multiparametric prostate MRI examinations with annotated solutions based on PI-RADS version 2. Three second-year radiology residents evaluated a separate set of 60 prostate MRI examinations both before and after review of the online case material, identifying and scoring dominant lesions...

PURPOSE: To evaluate whether in the setting of negative diagnostic mammogram for breast pain additional ultrasound is necessary. METHODS: Retrospective IRB-approved review of our database identified 8085 women who underwent ultrasound evaluation for breast pain from 1/1/2013-12/31/2013. Of 8085 women, 559 women had mammogram evaluation preceding the ultrasound and these women comprise the basis of this study. The patient's age, type of mammogram examination (screening or diagnostic), Breast Imaging-Reporting and Data System (BI-RADS) breast density (BD), type of breast pain (focal, diffuse, cyclical, unilateral, bilateral), additional breast symptoms (palpable concern, nipple discharge, skin changes, others), mammogram or ultrasound findings and final BI-RADS assessment, follow-up imaging, and follow-up biopsy results were reviewed and recorded...

BACKGROUND: Bronchiectasis is one of the causes of non-resolving, persistent or recurrent pulmonary infection which, if uncorrected may have deleterious consequences on the lung parenchyma and pulmonary circulation. High-resolution computed tomography (HRCT) is needed for the confirmation, localization and directing management accordingly. CONTENTS: Bronchiectasis is one of the major cause of morbidity worldwide. Chest radiograph is done at the initial suspicion which is supplemented by HRCT to confirm the diagnosis...

OBJECTIVE: Thyroid nodules are prevalent in over half the general population. Several multidisciplinary societies have management recommendations. However, the majority of data to support these guidelines are derived from studies of predominantly younger and female populations. This study's aim was to evaluate characteristics of thyroid nodules in a largely older and male Veteran population and apply these findings prospectively to reduce unnecessary thyroid fine needle aspiration (FNA)...

INTRODUCTION: We came across 3 cases of Balo's concentric sclerosis (BCS). The first of these patients presented to an outside hospital and was transferred to our institution due to complications resulting from a biopsy. The other 2 patients, despite having a characteristic imaging appearance and despite insistence on our part on the diagnosis of BCS, underwent a surgical procedure, which could have been prevented. This led us to review the available literature on BCS. MATERIAL AND METHODS: A total of 68 patients diagnosed with BCS between 1995 and 2015 were studied and the data collected for the clinical presentation and course, imaging, spinal fluid analysis, treatment, and clinical and imaging outcome...

With integration of the Radiological Information Systems (RIS), Picture Archiving and Communication systems (PACS), and reporting systems, patient identifiers and examination information can automatically map into examination reports. There are many potential benefits of report automation to radiologists including improvements in efficiency, accuracy, and fatigue. In this article we describe a 2 part study, with the first part being an anonymous survey of radiologists concerning report automation. A total of 13 staff radiologists and 9 radiology residents at a single institution completed an anonymous survey...

Effective leaders are essential to ensure the future of radiology. Radiologists often find themselves in leadership positions despite a lack of formal leadership training. The fourth year of residency is the ideal time to expose young physicians to leadership and extraclinical specialization, as such leadership development prior to fellowship may still impact academic career choice. In this manuscript, we discuss prior successes of leadership tracks within medicine and review the evidence supporting the saying that "leaders are made, not born"...

PURPOSE: Chemotherapy induced peripheral neuropathy (CIPN) is seen in up to 75% of treated cancer patients and can drastically limit their medical management and affect quality of life. Clinical and electrodiagnostic testing for CIPN have many pitfalls. Magnetic resonance neurography (MRN) is being increasingly used in the evaluation of peripheral nerves. Diffusion tensor imaging (DTI) shows promise in the workup of peripheral nerves. In this prospective pilot study, we investigated a possible relationship between DTI and peripheral neuropathy of the ankle and foot in cancer patients treated with chemotherapy...
