Adventitial cystic disease of veins is such a rare malady that only about 20 cases have been reported in the world literature. This low rate of reporting may be due to not only its low incidence but also to the difficulty of its diagnosis. A 52 year old man developed sudden painless edema of the left leg after physical abuse, and he was without any previous history of venous disease. He was found to have a bean-size cyst compressing the lumen of the left femoral vein. The intramural cyst was drained surgically and it was found to contain mucoid material. The patient has been followed up for about 11 months and he now has no venous problems in his left leg. Surgical excision and drainage shows a good result for treating the adventitial cystic disease of vein.
