Lymphedema is the edema that results from chronic lymphatic insufficiency. Lymphatic filariasis is caused by the filarial nematodes Wuchereria bancrofti, Brugia malayi, and Brugia timori. Lymphatic filariasis is common in tropical and subtropical regions. Early diagnosis and prompt therapy can be implemented using lymphoscintigraphy. Our patient is a 15-year-old boy presenting with a 3-month history of hydrocele. The patient was referred to us to rule out any lower limb lymphatic obstruction as the patient is from an endemic area. Tc Sulfur colloid (filtered) lymphoscintigraphy showed abnormal tracer collection in the scrotum and penis. There is associated dermal backflow or stasis in the left thigh region extending just above the knee, suggesting partial obstruction of left inguinal lymphatic channels.
淋巴水肿是由慢性淋巴功能不全引起的水肿。淋巴丝虫病是由丝虫属的班氏吴策线虫、马来丝虫和帝汶丝虫引起的。淋巴丝虫病常见于热带和亚热带地区。早期诊断和及时治疗可采用淋巴闪烁显像术。我们的患者是一名 15 岁男孩，有 3 个月的阴囊积水病史。由于患者来自流行地区，我们建议他来医院以排除任何下肢淋巴阻塞的可能。Tc 硫胶体（过滤）淋巴闪烁显像显示阴囊和阴茎有异常示踪剂聚集。左侧大腿区域在膝关节上方有相关的真皮逆流或停滞，提示左侧腹股沟淋巴管部分阻塞。
