On day-to-day imaging of the abdomen and pelvis, radiologists often encounter incidental musculoskeletal (MSK) findings. The purpose of this exhibit is to review commonly encountered MSK findings and help radiologists understand which findings necessitate further workup and referral.

Educational Goals / Teaching Points
The educational goals of this exhibit are to review commonly encountered MSK pathology on routine abdominal and pelvic imaging, to identify MSK pathology that requires further evaluation or specialty referral, and to provide a structured approach to the differential diagnoses based on the location and appearance of the findings.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
The anatomic findings that we will be presenting in this exhibit will be divided into six major categories, including soft tissue masses (for example, fluid-filled bursae, heterotopic ossification); bone tumors, both benign and malignant; pathology of the spine, sacroiliac joints, and hip joints (ankylosing spondylitis, sacroiliitis, sacral insufficiency fractures, avascular necrosis, discitis-osteomyelitis); hardware complications (particle disease, hardware malalignment, loosening); systemic conditions (hyperparathyroidism, sickle cell disease, renal osteodystrophy); and congenital and developmental anomalies (acetabular dysplasia, limbus vertebra, vertebral fusion anomalies).

While many MSK findings can be benign, it is imperative for the radiologist to know which diagnoses need further workup and evaluation, especially if the finding can lead to significant morbidity in the future.
