Calcification of the epiglottis presenting as foreign body sensation in the neck by Sunil Jeph et al. |
Published: 2017 Jun
Issue: 11(6) :: Pages: 1-5
| Abstract: The epiglottis plays an important role in preventing food of different consistencies from entering the airway during swallowing. Calcification of epiglottis can, potentially, alter and limit its movement causing aspiration amongst other swallowing problems. Isolated calcification of the epiglottis and its clinical presentation remains a poorly understood entity for radiologists as well as clinicians. Therefore, it is important to recognize the imaging features of epiglottic calcification, and it`s known clinical presentations to help clinicians with early diagnosis and management.

Endovascular retrieval of Greenfield IVC filters 13 and 19 years post placement without major complication by Junjian Huang et al. |
Published: 2017 Jun
Issue: 11(6) :: Pages: 15-25
| Abstract: Inferior vena cava (IVC) filters were first introduced in 1967 by Kazi Mobin-Uddin and later improved by Lazar Greenfield in the 1980s becoming a major component of catastrophic pulmonary embolism prevention. Nevertheless, filters are not entirely harmless. The long term risks include caval thrombosis, visceral penetration, and filters can serve as a nidus for infection. Filter retrieval is often complicated by intimal hyperplasia especially with increased indwelling time. Historically, Greenfield filters in place for longer than 3 weeks were considered permanent due to the risks of retrieval. Herein we present 2 cases of successful retrieval of Greenfield filters 13 and 19 years post implantation.

Systemic Air Embolism after Percutaneous Lung Biopsy: A Manageable Complication by Lucas Fiore et al. |
Published: 2017 Jun
Issue: 11(6) :: Pages: 6-14
| Abstract: CT-guided percutaneous biopsy is a resourceful and widely used tool to evaluate pulmonary nodules that frequently avoids costly and unnecessary surgeries. Severe complications occur in less than 1% of cases and include gas embolism, which is rarely documented. We report a case of gas embolism after transthoracic biopsies and discuss the pathophysiology and the benefits of early diagnosis and proper management.

A pictorial review of reconstructive foot and ankle surgery: evaluation and intervention of the flatfoot deformity by Andrew J Meyr et al. |
Published: 2017 Jun
Issue: 11(6) :: Pages: 26-36
| Abstract: This pictorial review focuses on basic procedures performed within the field of podiatric surgery, specifically for elective reconstruction of the midfoot and rearfoot with focus on the flatfoot deformity. Our goal is to demonstrate objective radiographic parameters that surgeons utilize to initially define the deformity, lead to procedure selection, and judge post-operative outcomes. We hope that radiologists will employ this information to improve their assessment of post-operative radiographs following reconstructive foot surgeries. First, relevant radiographic measurements are defined and their role in procedure selection explained. Second, the specific surgical procedures of the Evans calcaneal osteotomy, medial calcaneal slide osteotomy, Cotton osteotomy, subtalar joint arthroeresis, and arthrodeses of the rearfoot are described. Finally, specific plain film radiographic findings that judge post-operative outcomes for each procedure are detailed.
