Shock refers to a critical and potentially life-threatening condition in which the body's organs and tissues do not receive an adequate supply of blood and oxygen to function properly. Medical imaging can unveil various signs that are associated with shock. This paper delves into these distinct imaging findings collectively referred to as the 'hypovolemic shock complex (HSC).' Traditionally associated with hemorrhagic and hypovolemic shock, these findings can extend to all types of shock. The paper navigates through specific organs and systems affected by shock, ranging from the heart and vascular system to the liver, spleen, kidneys, and more. Radiologists' prompt recognition of crucial imaging indicators not only aids in prognosis and management, but also enables enhanced risk assessment through timely radiographic detection.

Educational Goals / Teaching Points
Describe the core features of HSC and corresponding pathophysiology; identify those features in imaging; discuss the varying degrees of specificity and sensitivity of features in HSC to aid in diagnosis; evaluate the variance in response to different types of shock in different organ systems; learn to interpret the etiology of features in HSC in the context of specific illness presentations.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
The radiologic features of HSC have been instrumental in identifying early or developing cases of shock and when clinical presentation is insufficient to meet a diagnosis. By reviewing multiple examples of shock with distinct causes, we can demonstrate the significance of aggregating multiple HSC signs in a systemic evaluation to diagnose shock. These cases will also allow us to discuss the most frequent and predictive findings to develop a method to examine image-guided diagnosis of shock.

Shock is a phenomenon that has distinctive features in radiology but is most often evaluated clinically. When the assessment of shock is unclear, HSC findings provide clarity for diagnosis and can even aid in finding etiology. This case-based review intends to provide a summary of the most up-to-date research findings of HSC, limitations of HSC features, and the utility of HSC as a model for understanding radiologic phenomenon across all forms of shock.
