[Pseudo-membranous colitis. 10 cases (author's transl)].

Pseudo-membranous colitis may develop after treatment with antibiotics, and in particular lincomycin a, d clindamycin. A "thumbprint" appearance of lacunae 2 to 4 mm in diameter, in substraction in relation to the wall of the colon, diffuse involvement of the colon and the regression of these signs when antibiotics are stopped are the typical radiological signs of this disorder.
