Background
Although COVID-19 predominantly affects the respiratory system, it has become apparent that many other organ systems can also be involved. Viral targeting of the abdominal and pelvic organs results in injury and, in some cases, organ failure. Imaging plays an essential role in the diagnosis of abdominal and pelvic manifestations of the disease and its related complications – proper utilization and interpretation of imaging examinations is crucial. A comprehensive understanding of the diagnostic imaging hallmarks, imaging features, multisystem involvement, and evolution of imaging findings is essential for effective patient management and treatment.

Educational Goals / Teaching Points
The goal of this exhibit is to familiarize radiologists with the spectrum of abdominal and pelvic imaging manifestations of COVID-19 to ensure prompt diagnosis and thereby facilitate appropriate patient care and hopefully improve the recovery rate from infection.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
The exhibit will review pathophysiology of virus cell entry and immune system activation (resulting in cytokine storm); discuss pathophysiology of hypercoagulable states that lie at the heart of vascular abdominal complications; review the role of imaging in the diagnosis of abdominal and pelvic manifestation of COVID-19 and its related complications; and discuss imaging findings of common and rare COVID-19 manifestations and complications in the abdomen and pelvis.

Conclusion
Imaging plays an essential role in the detection, diagnosis, assessment, and follow up of viral-induced injury, as well as its associated complications. An understanding of viral pathophysiology, particularly its effects on the immune system and coagulation, is essential for accurate identification of associated complications. The recognition of one complication should prompt intense scrutiny for others, particularly if patients are critically ill.
