“Eraseroma” as a cause of rhinolith: CT and MRI in a child

Abstract

We report a 5-year old girl with progressive difficulty in breathing through the nose whose clinical diagnosis was nasal tumour. CT showed a calcified nodular mass and MRI a nonspecific nodular lesion in the right nasal cavity. The radiological suspicion was a rhinolith. The operative specimen showed that an eraser from a pencil was the primary source. We underline the rarity of this entity and the important role of radiological studies in preoperative recognition.
