Giant rhinolith: a case report.

A rhinolith is a stone that forms in the nose. It occurs as a result of the solidification of mucus and nasal debris by mineral salts, calcium, magnesium phosphate and carbonate. It can be seen on radiographs as a radiopaque object in the nasal fossa and may be confused with several pathologic entities that will call for more invasive surgical procedures. We present the first case of a giant rhinolith, possibly arising from aspergillosis, and discuss its clinical and radiologic features.
