Background
Systemic diseases can affect multiple organ systems including the musculoskeletal system and some of these conditions have characteristic imaging findings in the foot. Recognition of these imaging findings will assist in early diagnosis of systemic diseases and prevent unnecessary testing and workup.

Educational Goals / Teaching Points
Provide a review of systemic diseases with classical imaging findings in the foot through a case-based presentation. Review common clinical presentations and how clinical history and additional imaging can aid in making a diagnosis.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Foot findings can be well evaluated on weight bearing radiographs. However, CT and MRI can be helpful for assessing complex osseous deformities and marrow abnormalities. Having a systematic approach in evaluating for abnormalities of the joint space, bones, and soft tissues is important. This presentation will systematically review major categories of systemic diseases with classical foot findings on imaging including: arthritis (gout, psoriasis, rheumatoid, reactive), autoimmune disease (systemic lupus erythematosus, sarcoidosis), connective tissue disorders (osteogenesis imperfecta, Marfan, Ehlers-Danlos), metabolic disorders (diabetes), vascular disorders (sickle cell, hemophilia), neoplasia (enchondromatosis, acromegaly osteochondromatosis, metastasis, neurofibromatosis), infection (diabetes), neurologic disorders (Charcot-Marie-Tooth, cerebral palsy, reflex sympathetic dystrophy), and congenital limb deformities (amniotic band syndrome, Apert, Turner).

Conclusion
Identifying characteristic imaging findings in the foot in patients with underlying systemic diseases will assist in the early diagnosis and proper management of these patients.
