[Sonography in acute diverticulitis of the sigmoid colon]. / Sonographie bei akuter Sigma-divertikulitis.

Sonography is the primary diagnostic method in the painful left lower quadrant. Experienced investigators can diagnose an acute diverticulitis in more than 90%. In unclear cases or when complications are suspected, CT should be performed. Sonography can diagnose most differential diagnosis of the painful left lower quadrant as colitis, appenagitis or haematomas.
