ReviewThe Role of Magnetic Resonance Imaging in Athletic Pubalgia and Core Muscle Injury.
Magnetic resonance imaging (MRI) has become the standard of care imaging modality for a difficult, often misunderstood spectrum of musculoskeletal injury termed athletic pubalgia or core muscle injury. Armed with a dedicated noncontrast athletic pubalgia protocol and a late model phased array receiver coil, the musculoskeletal imager can play a great role in effective diagnosis and treatment planning for lesions, including osteitis pubis, midline pubic plate lesions, and rectus abdominis/adductor aponeurosis injury. Beyond these established patterns of MRI findings, there are many confounders and contributing pathologies about the pelvis in patients with activity related groin pain, including internal and periarticular derangements of the hip. The MRI is ideally suited to delineate the extent of expected injury and to identify the unexpected visceral and musculoskeletal lesions.

Computed tomography (CT) is often the primary imaging modality for the evaluation of sinonasal disease. For some indications, magnetic resonance imaging (MRI) may provide additional information. There are established indications for using MRI in complicated sinonasal inflammatory disease, invasive fungal sinus disease, and sinonasal mass lesions. ⋯ Magnetic resonance imaging in sinonasal disease can be used to further characterize the primary sinonasal disease process and to evaluate the extent of complications such as orbital or intracranial involvement. When MRI is used in sinonasal disease, it should be evaluated in the context of the clinical situation and CT imaging features. This will help radiologists provide a meaningful differential diagnosis to assist in clinical management.

ReviewMagnetic resonance imaging of infectious meningitis and ventriculitis in adults.
Magnetic resonance imaging findings of meningitis are usually nonspecific with respect to the causative pathogen because the brain response to these insults is similar in most cases. In this article, we will use a few representative cases to describe the characteristic magnetic resonance findings of meningitis and its complications, including ventriculitis.

Pediatric congenital intracranial infections are a group of different and important entities that constitute a small percentage of all pediatric infections. The causal factors and clinical presentations are different in children compared with adults. ⋯ Despite improvements in prenatal screening, vaccine safety, and antibiotics, infections of the central nervous system remain an important cause of neurological disabilities worldwide. This article reviews the most common congenital infections and their imaging findings.
