title: A colonic splenic flexure tumour presenting as an empyema thoracis: a case report.
abstract: BACKGROUND
  The case report describes the rare presentation of a 79-year-old patient with a locally perforated splenic flexure tumour of the colon presenting with an apparent empyema thoracis in the absence of abdominal signs or symptoms.
  
  
  METHODS
  Initial presentation was with a non-productive cough, anorexia and general malaise. An admission chest X-ray and subsequent computed tomographic image of the thorax showed a loculated pleural effusion consistent with an empyema. The computed tomography also showed a thickened splenic flexure. Thoracotomy was performed and a defect in the diaphragm was revealed after the abscess had been evacuated. A laparotomy was carried out at which point a tumour of the splenic flexure of the colon was found to be invading the spleen and locally perforated with subsequent collection in communication with the thorax. The tumour and spleen were resected and a transverse end colostomy was fashioned.
  
  
  CONCLUSIONS
  One must consider the diagnosis of pathology inferior to the diaphragm when an apparent empyema thoracis is encountered even in the absence of clinical signs or symptoms.
