Not only fat: omental infarction and its mimics in children. Clinical and ultrasound findings: a pictorial review.

ABSTRACT: Acute abdominal pain in children is the most common cause of emergency department admissions. Omental infarction is a rare cause of acute abdominal pain in this age group, accounting for approximately 15% of cases in children and 0.024-0.1% of cases of surgery for suspected appendicitis at the same age. Its clinical presentation may mimic similar diseases such as acute appendicitis, epiploic appendagitis, and mesenteric panniculitis. Ultrasound is the modality of choice for the initial evaluation of acute abdominal pain in pediatric patients and it can be used with confidence in the diagnosis and management of omental infarction in children. In this brief review, we focus on the main ultrasound findings and their diagnostic clue for omental infarction and its mimics.

Project description:OBJECTIVES: To illustrate the clinical and radiological features of idiopathic interstitial pneumonias (IIPs), according to the American Thoracic Society (ATS)/European Respiratory Society (ERS) classification updated in 2013. METHODS: IIPs include a subset of diffuse and restrictive lung diseases, resulting from damage to the parenchyma characterised by inflammation and fibrosis of the interstitium. Classification into major and rare IIPs is based on the 2013 ATS/ERS committee. RESULTS: The diagnosis of idiopathic pulmonary fibrosis (IPF) needs to exclude other well-known causes of interstitial lung diseases. According to the 2011 evidence-based guidelines, usual interstitial pneumonia (UIP) can be diagnosed by HRCT when all criteria are fulfilled. Non-specific interstitial pneumonia (NSIP) is characterised by patchy ground-glass opacities and irregular linear/reticular opacities. The imaging patterns of respiratory bronchiolitis associated-interstitial lung disease (RB-ILD) and desquamative interstitial pneumonia (DIP) show centrolobular nodules and ground-glass opacities. Cryptogenic organising pneumonia (COP) consists of patchy peripheral or peribronchial consolidations, while ground-glass opacities are typically associated with diffuse lung consolidation, evolving to fibrosis, in acute interstitial pneumonia (AIP). Rare IIPs include lymphoid interstitial pneumonia and idiopathic pleuro-parenchymal fibroelastosis (IPPFE). CONCLUSIONS: The knowledge of IIP imaging features on HRCT images help radiologists in diagnosis. Moreover, the overlap of imaging features needs a multidisciplinary approach. TEACHING POINTS: • UIP findings are reticulations, bronchiectasis, honeycombing and absence of inconsistent features. • Bilateral patchy ground-glass areas represent the most encountered features in NSIP. • Poorly defined centrilobular nodules are typical of RB-ILD, whereas a ground-glass appearance is typical of DIP. • HRCT features of COP include characteristic peripheral or peribronchial patchy consolidations. • Rare IIPs include idiopathic LIP and idiopathic pleuro-parenchymal fibroelastosis (PPFE).
