1. Structures carefully evaluated as part of a standard search pattern on abdominal and pelvic imaging have the potential to be overlooked on spine imaging. 2. Due to a limited field of view, exam indication and satisfaction of search, extra-spinal findings may be missed on spine imaging. 3. The audience will learn to recognize potential blind spots in lumbar spine imaging. The importance of these blind spots will be illustrated. 4. A diagnostic approach to extra-spinal findings on lumbar spine imaging will be reviewed.

Extra-spinal abnormalities will first be shown on dedicated spine imaging, highlighting typical blind spots on lumbar spine studies. The same findings will then be shown to better advantage on dedicated abdominal/pelvic studies. Cases will be presented in quiz format and will include the following: I. Abdomen    A. Adrenal gland - adenoma, adrenocortical carcinoma    B. Liver - FNH, adenoma, HCC    C. Pancreas - pancreatitis, neoplasm, laceration    D. Spleen - splenomegaly, laceration    E. Kidneys - hydronephrosis, Lithium nephropathy, RCC    F. Carcinoid II. Pelvis    A. Adnexa - mucinous cystadenoma    B. Uterus - leiomyoma III. Vascular    A. Aorta - aneurysm, dissection, thrombosis    B. Other - pelvic varices IV. Error analysis V. Diagnostic checklist
