[The enhancement phenomenon of serous cavity effusions].
The enhancement of ascites following a high dose of contrast medium has been recently described. The CT behavior of 26 peritoneal, pleural or pericardial effusions has been studied in 23 patients after the administration of a high dose of urographic contrast medium. The effusions were enhanced in all patients but one. No difference between malignant and non-malignant effusions could be observed with ionic and non-ionic contrast medium. Low molecular weight of the urographic contrast medium (600-800 daltons) can explain the free passage of the solute through peritoneum, pleura, and pericardium. The knowledge of such a phenomenon is mandatory to avoid misdiagnosing hematic effusion or urinary-peritoneal fistula.
