Susan Jane Buckingham MBChB, Abstract Co-Author: Nothing to Disclose

The aim of this exhibit is to Review the pathophysiology of sarcoidosis Demonstrate the typical radiological features of sarcoid within the chest, abdomen and central nervous system Share some particularly good cases of sarcoid mimicking other conditions and the key features that suggest sarcoid could be the underlying cause

The Pathophysiology of Sarcoidosis Typical Radiological Features (radiography, CT, MRI) Chest Abdomen Central Nervous System Sarcoid as mimic of other pathology - illustrative cases and tell tale signs all is not what it seems (Including, amongst others, cases of sarcoid masquerading as metastatic bowel cancer (granulomatous colitis with necrotic lymphadenopathy and multiple pulmonary lesions) and mimicking high grade lymphoma with extensive bone marrow involvement (lymphadenopathy and diffuse bone FDG avidity on PET-CT). All cases presented were subsequently biopsy proven to represent sarcoidosis) Summary
