[Rectocolic lymph node appearance in adults (author's transl)].
A very characteristic rectocolic "lymph follicle appearance" was observed on radiological examination by double contrast enemas in 3.5 p. cent of 480 cases explored. The usual typical appearance is that of small lacunae of 1 to 3 mm in diameter, with indistinct borders, extending through several colon segments. The frequency with which these images are observed is probably a function of the double contrast technique employed, particularly the adherence of the barium. In most cases, the "lymph follicle appearance" is a variation of the normal, but several rare forms could result from a partial immunity deficiency. Differential diagnosis includes colon wall oedema and most polyposis disorders in their initial stages. Coloscopy with biopsy is necessary when diagnosis is uncertain.
