Giant Ethmoidal Rhinolith: A Case Report

Rhinolithiasis is a rare condition with an unrecognized etiopathogenesis. We discuss the case of an adult cocaine user complaining of chronic headache with chronic left unilateral nasosinus symptoms. The blonde scan revealed ethmoidal calcium opacity. The extraction was performed by endonasal endoscopy under scannographic identification by digipointer. The postoperative follow-up is simple. The course is favorable with disappearance of nasosinus symptoms and pain, without signs of recurrence three years later.
