Shisha smoking as a possible cause of bilateral granulomatous lung lesions.

A 19-year-old male who regularly smoked tobacco shisha pipes presented with pleuritic chest pain, dyspnoea, and cough. He was found to have multiple bilateral lung nodules on computed tomography. A biopsy of the lung revealed necrotizing granulomatous inflammation but without evidence of infection, foreign body, vasculitis, or malignancy. There was spontaneous and complete clinical and radiographic resolution over the next 12 weeks following cessation of shisha use.
