The cecal diverticulitis was first described by Portier in 1912. A right sided diverticulitis can be located in the cecum or the ascending colon. A right sided or cecal diverticulitis is fairly uncommon especially in the Caucasian population. In the Asian population it is more common. The right sided diverticulitis is less frequent than the left sided divericulitis. Males are slightly more affected than females. In the case presented there was a solitary diverticulum. These solitary diverticula are usually true diverticula and the diverticulum involves all layers of the colon wall. They are considered congenital diverticula. The left sided diverticula are considered false diverticula and do not contain a muscle layer. These diverticula are considered to be acquired. In severe cases of acquired diverticulitis the right side of the colon can also be involved. That was not the case in this patient. Because the right sided diverticulum is a true diverticulum which involves all the layers of the wall they do not perforate as easily as the left sided diverticulitis.

The typical sonographic feature of a right sided diverticulitis is a rounded or oval-shaped hypoechoic or nearly anechoic structure protruding out from the segmentally thickened colon wall. Some of them as in this case can contain strong echoes representing gas or feces or a stone in the lumen. Regional pericolic or peridiverticular fat thickening with increased echogenicity is a frequent finding

The patient was operated and underwent a ileocecectomy. The pathologist confirmed the diagnosis
