Lymphangiomas are congenital malformations of the lymphatic system, mostly well-circumscribed and cystic. Although many theories were proposed to explain etiology, it is still controversial. Most of these lesions are found in the cervicofacial region, while the scalp is considered a scarce location, with only a few reported cases in the literature. Herein, we report a case of scalp lymphangioma in a 33-year-old male, which unexpectedly and significantly progressed in size over one year. The MRI scan characteristics were unique compared to the literature description of the lymphangioma, as it appeared hypointense in both T1WI and T2WI with inhomogeneous contrast enhancement, eventually consistent with lymphangioma on histopathology. The patient underwent surgical excision of the mass without any recurrence over a follow-up period of 1 year.
淋巴管瘤是淋巴系统的先天性畸形，大多边界清晰且呈囊性。尽管提出了许多理论来解释其病因，但仍存在争议。这些病变大多见于头颈部区域，而头皮被认为是少见部位，文献中仅有少数病例报道。在此，我们报告一例33岁男性头皮淋巴管瘤，其大小在一年内意外且显著增大。与文献中淋巴管瘤的描述相比，该病例的MRI扫描特征独特，在T1WI和T2WI上均呈低信号，增强扫描不均匀，最终组织病理学结果符合淋巴管瘤。患者接受了肿物手术切除，随访1年无复发。
