[Granulomatous colitis associated with diverticular disease. Report of a case]

We report the case of a 71 years old lady with clinical and radiological evidence of colonic obstruction due to diverticulosis. A segmentary resection of the sigmoid colon was performed and the diagnosis of diverticulosis and Crohn's disease was made in the surgical specimen. The patient is doing well and no further extension of the colonic granulomatosis has been found 8 months after surgery. In spite of the great frequency of diverticulosis in the elderly its association with Crohn's disease is quite uncommon. This is probably due to the infrequency of colonic Crohn's disease in this population, particularly of the segmentary type. A few cases of segmentary colonic Crohn's disease that were cured after resection have been published. Even though the postoperative period of our patient is too short for making a good prognosis. Crohn's disease is a chronic relapsing disease and frequency of recurrences is closely related with long term evolution.
