E1552. Acute Right Iliac Fossa Pain: Cross-Sectional Imaging Spectrum-Common, Rare and Exotic
UT Health San Antonio
St. Vincent's Medical Center
Ohio State University Wexner Medical Center
Acute right iliac fossa pain is a common presentation to the emergency department and can be secondary to a wide spectrum of causes. If left untreated, some of those conditions can result in significant morbidity and mortality. Imaging plays a vital role in the management of these emergencies by identifying them and also aids in the detection of complications. The purpose of this exhibit is to provide a detailed review of a wide spectrum of entities that can present to the emergency department with right iliac fossa pain and to discuss the role imaging, particularly multidetector computed tomography (MDCT) in the evaluation of these patients.
Educational Goals / Teaching Points
1. To describe the imaging manifestations of a wide variety of conditions which present with right iliac fossa pain and discuss the clinical manifestations of specific imaging findings.
2. To discuss the diagnostic strategy in these patients.
3. To discuss the role of imaging in the management of these patients.
Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
A wide spectrum of conditions present clinically with right iliac fossa pain to the emergency department and require early and accurate diagnosis for prompt treatment. These include acute appendicitis and other appendiceal pathologies like epipolic appendagitis of the appendix, cecal diverticulitis, typhlitis, Meckels diverticulitis, ovarian and tubal torsion etc. MDCT is both highly sensitive and specific in the detection of these conditions and is well suited for reliable depiction of the underlying cause and associated complications.
Imaging plays a key role in the evaluation of patients presenting with right iliac fossa pain. Knowledge of various entities and their imaging features can help the emergency radiologist to promptly triage the patients, thereby facilitating appropriate management.
