Lymphoscintigraphy is a useful technique for the evaluation of lymphatic function in the presence of limb swelling. The authors report a case where genital swelling in a 20-year-old man was investigated by lymphoscintigraphy. We performed lower limb lymphoscintigraphy and scrotal lymphoscintigraphy in the patient on two different days. Lower limb revealed dermal backflow pattern in lower limbs, inguinoscrotal reflux of the lymph and unexpected avid radiotracer uptake in the axillae bilaterally. Scrotal lymphoscintigraphy revealed slow movement of the lymph from the scrotal skin and again unexpected avid radiotracer uptake in the axillae bilaterally. Findings were concluded as congenital hypoplasia of lymphatics in lower limbs, congenital lymphectasia/compensatory megalymphatics in scrotum and aberrant lymphatic pathway, possibly due to malfunctioning/nonfunctioning thoracic duct.
淋巴闪烁造影术是评估肢体肿胀情况下淋巴功能的一项有用技术。作者报告了一例通过淋巴闪烁造影术对一名20岁男性生殖器肿胀进行检查的病例。我们在两天内分别对该患者进行了下肢淋巴闪烁造影术和阴囊淋巴闪烁造影术。下肢淋巴闪烁造影显示下肢有真皮反流模式、腹股沟阴囊淋巴反流以及双侧腋窝意外摄取大量放射性示踪剂。阴囊淋巴闪烁造影显示淋巴从阴囊皮肤移动缓慢，双侧腋窝同样意外摄取大量放射性示踪剂。结论为下肢淋巴管先天性发育不全、阴囊先天性淋巴管扩张/代偿性巨淋巴管形成以及异常淋巴通路，可能是由于胸导管功能异常/无功能所致。
