Sickle cell disease is a common inherited disorder due to a structural abnormality in hemoglobin affecting the shape of the red blood cells. There are a variety of manifestations of this disease affecting a multitude of different organ systems. Some of the complications with the highest morbidity are those involving the central nervous system, and thus, the radiologist plays a pivotal role in the clinical management of these patients. It is important for the radiologist to understand the disease process, the radiologic manifestations, and the screening modalities available. Read More

Omental infarction and epiploic appendagitis are subtypes of a broader entity of abdominal fat necrosis known as intraperitoneal focal fat infarction (IFFI). IFFI is an uncommon cause of acute abdominal pain in children, and a known mimicker of acute appendicitis. The CT appearance of IFFI is well described, but the appearance is less familiar on MRI and is a potential imaging pitfall. Familiarity with the MRI appearance of IFFI is particularly timely, given the growing use of MRI in the evaluation of right lower quadrant pain in children. The purpose of this educational exhibit is to review the clinical history, pathologic appearance and treatment of IFFI, and describe MRI features that will allow the radiologist to make the correct diagnosis.

CHD (congenital heart disease) occurs in approximately 1% of all live births with more than 90% survival into adulthood. Prevalence of coronary artery disease has been reported to be similar to general adult population. Patients with complex CHD may be subjected to non-atherosclerotic premature coronary artery disease due to anomalous coronaries, peri-coronary region interventions, or coronary re-implantation. Cardiac MRI (CMR) may provide valuable myocardium health information with pointers towards a coronary distribution in unsuspected chronic or acute cases. Acquisition of delayed enhancement sequences (LGE) and T1 mapping should be considered routine in CMR studies for assessment of interval ischemic events. Patients with complex CHD are also at risk for sudden cardiac arrest and LGE data may assist in further risk stratification of these patients. Three complex CHD patients who all suffered myocardial infarctions at a young age as a result of their multifaceted cardiac history are highlighted to illustrate the importance of this (see included table, Figure 1). Two CMR images (Figures 2,3) demonstrate delayed enhancement throughout the septum at the base to mid-cavity in a patient with truncus arteriosus type 1 who presented with a non-ST-elevation myocardial infarction (NSTEMI). Focal area of low-signal sub-endocaridum within the enhancement on Figure 3 favors microvascular obstruction.

CMR is a vital component of surgical planning and post-operative care of patients with CHD, providing accurate anatomical, functional, and flow information that assists in clinical management. Delayed enhancement sequences and post-gadolinium T1 mapping allow assessment of ischemic injury or infarct, and therefore should be considered part of routine follow up CMR studies in patients with complex CHD.
