医学影像英语每日读丨66.Venolymphatic Malformation

每天朗读一段医学影像学英语文章

朗读者：Aimee

In this pediatric patient, we see a lobulated multiloculated T2 hyperintense mass in the left parotid space, extending to the submandibular region. On the post-contrast images, there is some associated enhancement with several prominent associated vessels, but the majority of the lesion does not enhance.

This is most consistent with a venolymphatic malformation with enhancing venous and non-enhancing lymphatic components. Most of these lesions are typically evident by two years of age if not obvious at birth.

Treatment may involve a spectrum of surgical interventions or percutaneous scleotherapy. Characteristics of the individual types of lesions include transpacial nonenhancing components for lymphatic malformations and enhancing masses associated with phlebolith (静脉石）for venous malformations. The patient in this case was being evaluated for percutaneous sclerotherapy.

T2图像可见该小儿患者左侧腮腺间隙一分叶状多房高信号肿块，病变延伸至颌下区。增强后可见若干主要血管强化，但大部分病灶未见强化。
以上影像学征象符合静脉-淋巴管畸形，伴静脉强化和无强化的淋巴结构。大多病变若在出生时不明显，则两岁时会出现明显症状。
治疗方法包括一系列的手术干预或经皮硬化疗法。病变不同分型的特征包括无强化的淋巴畸形和有静脉石的、呈团块样、强化的静脉畸形。该患者推荐经皮硬化疗法。
