title: Primary peritoneal adenocarcinoma causes pleural effusion.
abstract: BACKGROUND
  The most common malignancies associated with malignant pleural effusions are carcinomas of the breast, lung, gastrointestinal tract, ovary and lymphomas. Primary peritoneal adenocarcinoma is a very rare cause of malignant pleural effusion.
  
  
  METHODS
  A 72-year old female patient presented to us with shortness of breath for the last 2 months. A contrast-enhanced computed tomography (CECT) scan of her-thorax revealed only bilateral pleural effusion with absence of any mass lesion or any mediastinal lymphadenopathy. A cytologic examination of pleural fluid revealed adenocarcinoma cells. A CECT of her abdomen and pelvis revealed heterogenous thickening of omentum with nodular appearances and small amount of ascites. Her ovaries were normal and no other mass lesion was detected. A histological examination of a peritoneal lesion was suggestive of adenocarcinoma.
  
  
  CONCLUSIONS
  The patient was diagnosed with a rare case of primary peritoneal adenocarcinoma with bilateral pleural effusion.
