Juvenile granulosa cell tumor associated with Maffucci syndrome in pregnancy: A case report.

Clin Imaging 2019 Mar 13;56:77-80. Epub 2019 Mar 13.

New York Presbyterian Hospital-Weill Cornell Medical Center, New York, NY, USA.

Juvenile granulosa cell tumor (JGCT) is an extremely rare ovarian tumor that has been associated with Maffucci syndrome. It both secretes hormone and has been postulated to grow in response to hormone. We present a case of a 33-year-old G1P0 asymptomatic woman with a history of Maffucci syndrome found to have a left adnexal mass on routine ultrasonography at 13 weeks gestation. Read More

Department of Diagnostic Radiology, Michigan Medicine, 1500 E Medical Center Dr, Ann Arbor, MI 48109, USA.

Retropharyngeal carotid arteries are a common clinically relevant anatomic variant. "Peripatetic" carotid arteries refer to change in position to and from a retropharyngeal location, and are a newly described finding. Knowledge of this phenomenon is important to avoid potential procedural complications as well as misdiagnosis. Read More

Combined task activation display as an effective method to teach introductory fMRI users.

Clin Imaging 2019 Mar 29;55:181-187. Epub 2019 Mar 29.

Department of Radiology and Imaging Sciences, Division of Neuroradiology, Emory University Hospital, Atlanta, GA, United States of America. Electronic address:

Rationale And Objectives: Interpreting functional magnetic resonance imaging (fMRI) can be an overwhelming and challenging task for trainees, particularly when post processing, synthesizing and interpreting data from multiple language paradigms. Currently, there is no established best method for teaching fMRI interpretation to new trainees. The purpose of our study is to compare the use of combined task activation display (CTAD) and conventional display of fMRI language paradigms as an effective method to teach fMRI to the introductory learner.

Clin Imaging 2019 Mar 11;55:165-173. Epub 2019 Mar 11.

Department of Radiology, Seoul National University Bundang Hospital, 82, Gumi-ro 173beon-gil, Bundang-gu, Seongnam-si, Gyeonggi-do, Republic of Korea.

Cough-induced costal cartilage fracture.

Clin Imaging 2019 Mar 13;55:161-164. Epub 2019 Mar 13.

Department of Radiology, New York Presbyterian Hospital-Weill Cornell Medical Center, 525 East 68th Street, Box 141, New York, NY 10065, United States of America.

We present two cases of atraumatic costal cartilage fracture secondary to violent coughing. Although costal cartilage fractures due to trauma and bony rib fractures due to violent coughing have been described, to our knowledge there have been no prior reported cases of cough-induced costal cartilage fracture. It is important for radiologists to consider costal cartilage fractures, which are often more subtle than osseous injuries, in patients with chest pain, and understand that they may not always be preceded by direct trauma.

Colostomy on CT and fluoroscopy: What the radiologist needs to know.

Clin Imaging 2019 Feb 20;56:17-27. Epub 2019 Feb 20.

Department of Radiology, Montefiore Medical Center, Bronx, NY, United States of America.

Colostomies are commonly created in conjunction with colorectal surgery performed for both malignant and benign indications. Familiarity with the different types of colostomies and their normal imaging appearance will improve radiologic detection and characterization of colostomy complications. The radiologist plays a large role in assessment of colostomy patients either via fluoroscopic technique or multidetector computed tomography (CT) in order to help identify ostomy complications or to aid the surgeon prior to colostomy reversal.

Melorheostosis with an associated para-articular enhancing soft tissue mass.

Clin Imaging 2019 Feb 2;56:9-12. Epub 2019 Feb 2.

Department of Radiology, University of California, San Diego, United States of America.

Melorheostosis is a rare non-hereditary sclerosing bone dysplasia which predominantly affects the appendicular skeleton. Although melorheostosis is typically recognized as an osseous lesion, associated soft-tissue components have been reported. Advanced imaging with MRI may allow for more complete evaluation of these soft tissue components; however, there is little information regarding their MRI characteristics which may lead to confusion with malignant processes.

Clin Imaging 2019 Jan 11;55:95-99. Epub 2019 Jan 11.

Department of Radiology, University of Pennsylvania Perelman School of Medicine, Philadelphia, PA, United States of America.

Objective: Women with ovarian-sparing hysterectomy before 2007 are more likely to have retained Fallopian tube remnants which can become fluid-filled, distended masses, potentially mistaken for a cystic adnexal neoplasm on imaging. Here we assess the prevalence and appearance of hydrosalpinx in women with ovarian-sparing hysterectomy prior to 2007 referred for pelvic MRI.

Methods: A total of 3044 consecutive pelvic MRI exams performed over a two-year period (2003-2004) were selected from our radiology database and retrospectively reviewed. Read More

Department of Radiology, Division of Nuclear Medicine, University of Minnesota Medical Center, Minneapolis, MN, USA. Electronic address:

Introduction: The aim of this study is to determine whether Likert scale (Deauville criteria) can be used to classify oropharyngeal squamous cell cancer (OPSCC) patients as 'responders' and 'nonresponders' by utilizing FDG-PET/CT for primary tumor site. The second aim is to compare the performance of methods used in interpretation of posttreatment PET/CT scans (Likert scale, SUVmax, ratios of SUVmax primary lesion to mediastinum 'SUVmax P/M' and SUVmax primary lesion to liver 'SUVmax P/L') in predicting treatment response.

Methods: Seventy-seven PET/CT scans were assessed by Deauville criteria, five-point Likert scale. Read More

Clin Imaging 2019 Feb 7;55:76-82. Epub 2019 Feb 7.

Department of Radiology, University of Minnesota Medical Center, Minneapolis, MN, USA. Electronic address:

Purpose: To evaluate the potential contribution of quantitative DWI parameters including ADC and ADC values to help in distinguishing the histopathological types of sinonasal neoplasms.

Methods: This retrospective study included 83 patients (50 males, 33 females; mean age 61 years) with pathologically proven untreated sinonasal neoplasms who have undergone diffusion-weighted MRI imaging from February 2010 to August 2017.

Department of Radiology, Lenox Hill Hospital, 100 East 77th St, New York, NY 10075, United States of America. Electronic address:

Groin pain is a common complaint in the general population, with an underlying etiology that may be difficult to diagnose. Although uncommon, type I obturator hernias may be a significant source of chronic or refractory groin pain. In this review, we discuss the commonly missed findings of type I obturator hernias at CT and MRI, as well as correlate these findings with images obtained at the time of laparoscopic repair.

Clin Imaging 2019 Jan 23;55:23-28. Epub 2019 Jan 23.

Royal Marsden Hospital, United Kingdom of Great Britain and Northern Ireland.

Aim: To compare retrospectively fused FDG PET/CT and MRI (PET/MRI) to FDG PET/CT and MRI for characterisation of indeterminate focal liver lesions as malignant or benign in patients with a known primary malignancy.

Materials And Method: A retrospective review of 70 patients (30 females, 40 males; mean age 56 ± 14 years) with 150 indeterminate lesions after FDG PET/CT and MRI (mean scan time interval 21 ± 11 days). HERMES® software was used to fuse PET/CT and MRI scans which were reviewed by 2 readers using the Likert score (scale 1-5) to characterise lesions as benign (1-3) or malignant (4-5). Read More

Microvascular volume visualization utilizing computed tomographic angiography data facilitates resection of a complicated massive congenital hemangioma.

Clin Imaging 2019 Jan 17;55:8-11. Epub 2019 Jan 17.

Department of Radiology, University of Kentucky Chandler Medical Center, Lexington, KY, United States of America.

CT angiography (CTA) can be used for planning procedural and operative therapies for neonatal vascular lesions, such as congenital hemangiomas (CH), that are too morbid for medical therapy. Neonatal anatomy can be displayed within a small enough field-of-view that the nominal resolution of a modern CT scanner can be realized with a standard 512 × 512 storage matrix, yielding isometric ultrahigh resolution data and allowing for microvascular volume visualization. This case report details the creation and use of microvascular volume visualizations of CTA data during pre-procedural planning for treatment of this pathological entity. Read More
