Congenital pleuroperitoneal communication in a patient with pseudomyxoma peritonei.

BACKGROUND AND

OBJECTIVES

Pseudomyxoma peritonei syndrome is a rare disease arising from a perforated appendiceal adenoma. The syndrome is characterized by progressive accumulation of mucinous ascites and tumor within the peritoneal cavity. Direct extension of pseudomyxoma peritonei to the pleural cavity is uncommon and has been associated with surgical penetration of the diaphragm at the time of cytoreduction.

METHODS

We review the case of a patient who presented with mucoid peritoneal and pleural fluid consistent with spontaneous pleural spread of pseudomyxoma peritonei.

RESULTS

Surgical exploration confirmed direct pleuroperitoneal communication by macroscopic diaphragmatic fenestration.

CONCLUSIONS

This is a rare phenomenon. We outline a therapeutic approach to be applied when pleural involvement is suspected in patients with pseudomyxoma peritonei syndrome.
