POSTERIOR HEPATODIAPHRAGMATIC INTERPOSITION OF THE COLON COMPLICATED BY APPENDICITIS

Posterior hepatodiaphragmatic interposition is a rare malposition of t he cecum that persists over time but is usually of little or no clinic al importance. However, when inflammation occurs in the appendix, the symptoms and signs are those of subphrenic disease rather than abdomin al disease and may be misleading to the attending physicians. Radiolog ists should report the presence of anterior and posterior hepatodiaphr agmatic interposition and should differentiate between the two.
