Abstract

Conclusion: The characteristic ultrasound appearance of mucosa-associated lymphoid tissue (MALT) lymphoma of the head and neck provides diagnostic information regarding masses or swellings in the head and neck region. Objectives: There are only a few reports about ultrasound features of malignant lymphoma (ML) of the head and neck. We have noticed that the ultrasound appearances of cases with MALT lymphoma resembled each other even when the appearances of other images like computed tomography were absolutely different. The objective of this study was to delineate the reliability of this characteristic ultrasound appearance of MALT lymphoma of the head and neck. Methods: The ultrasound examinations of 30 patients with histopathologically proven primary ML of the head and neck (15 cases of MALT) were reviewed. The ultrasound results of each case were independently compared to the results of the histopathological examination. Results: Two ultrasound patterns were observed for MALT lymphoma. The first was characterized by a marked hypoechoic area with interspersed linear echogenic strands (linear echogenic strands pattern), and the second was characterized by multiple, relatively large, hypoechoic segments (segmental pattern). Histopathologically, these patterns could be explained on the basis of the expansion of lymphoma cells demarcated by narrow or wide fibrous bands.
