BACKGROUND: Extracorporeal shock wave lithotripsy has been widely used to treat renal stones. The procedure is relatively safe with minor complications.
CASE: The patient is a 32-year-old man who presented with left sided pleural effusion after extracorporeal shock wave lithotripsy.
RESULTS: The pleural effusion study revealed an exudative fluid rich in eosinophils (30%). So, the diagnosis of eosinophilic pleural effusion as a complication of lithotripsy was made.
CONCLUSION: Extracorporeal shock wave lithotripsy should be regarded as an etiology of unexplained eosinophilic pleural effusion after this procedure.

Eosinophilic pleural effusion is indeed a very unusual complication of SWL. It can be assumed that in the described patient shockwaves had been inappropriately focused.
