An unusual presentation of a high-grade, non-Hodgkin's lymphoma in the maxilla

A case of a high-grade, non-Hodgkin's lymphoma affecting the maxillary alveolus which exhibited the classical radiological features of a malignant lesion occurring in the jaws is presented. CT demonstrated considerable upward displacement of an expanded but intact antral floor. Such a feature is more usually suggestive of involvement of the antrum by a benign lesion arising within the alveolar bone.
