INTRODUCTION
Malignant lymphomas of the paranasal sinuses present with few symptoms
during the early stages. Thus, imaging studies are benefical for their
diagnosis. Magnetic resonance imaging (MRI), which has a higher density
resolution than that of computed tomography (CT), is useful for
diagnosing paranasal tumors.
We encountered a case of malignant lymphoma of the maxillary sinus in
which CT findings suggested malignancy but MRI findings suggested an
inflammatory disease.
