Abstract
OBJECTIVES
As an uncommon neoplasm, parotid non-Hodgkin lymphoma (NHL) comprises mucosa-associated lymphoid tissue (MALT) and non-MALT lymphomas. Both types of lymphoma vary in prognosis and treatment. The aim of this study was to explore CT and MRI characteristics of these two types of lymphoma.
METHODS
61 cases of parotid NHL, 34 MALT and 27 non-MALT lymphomas with histopathological confirmation were examined with routine CT and MR scans prior to treatment, and retrospectively reviewed.
RESULTS
On CT and MRI, 34 MALT lymphomas presented with 11 solid and 23 solid-cystic forms, whereas 27 non-MALT lymphomas presented with 25 solid and 2 solid-cystic forms (p < 0.01).
CONCLUSIONS
Parotid MALT lymphoma is characterized mainly by the solid-cystic form, whereas non-MALT lymphoma is characterized mainly by the solid form. The differences on CT and MRI can offer helpful information for differentiation of both types of parotid NHL.
摘要
目的
作为一种罕见的肿瘤，腮腺非霍奇金淋巴瘤（NHL）包括黏膜相关淋巴组织（MALT）和非 MALT 淋巴瘤。这两种类型的淋巴瘤在预后和治疗上存在差异。本研究旨在探讨这两种淋巴瘤的 CT 和 MRI 特征。
方法
对 61 例经组织病理学证实的腮腺 NHL，其中 34 例为 MALT 淋巴瘤和 27 例非 MALT 淋巴瘤患者，在治疗前进行常规 CT 和 MRI 检查，并进行回顾性分析。
结果
在 CT 和 MRI 上，34 例 MALT 淋巴瘤表现为 11 例实性和 23 例囊实性，而 27 例非 MALT 淋巴瘤表现为 25 例实性和 2 例囊实性（p<0.01）。
结论
腮腺 MALT 淋巴瘤主要表现为囊实性，而非 MALT 淋巴瘤主要表现为实性。CT 和 MRI 上的差异可为鉴别两种腮腺 NHL 提供有价值的信息。
