RESUMEN
This pictorial essay describes the most characteristic lesions and radiologic signs of Crohn disease of the small bowel: nodular lymphoid hyperplasia, abnormal mucosal folds, villous pattern, aphthous ulcerations, linear ulcerations, cobblestone pattern, string sign, target sign, comb sign, creeping fat, sinus tracts, fistulas, and abscesses. Each description includes the definition, a correlation with the pathologic findings, an explanation of the possible physiopathologic mechanism, sample radiologic images with air enteroclysis or MDCT, the correspondence with the endoscopic findings when possible, and a list of differential diagnoses.

Relapsing Polychondritis (RP) is a systemic condition characterized by chronic, episodic inflammation, especially of cartilaginous and proteoglycan-rich structures. The etiology of this rare autoimmune disease is unknown, and so far, there is very little data available for non-Caucasians. RP presents with a constellation of non-specific inflammation, which sometimes appear in characteristic locations. Radiology is important in supporting the diagnosis, and this paper presents a case of a non-Caucasian patient monitored radiologically from early onset to the terminal stages.
