Great saphenous vein aneurysm: A differential diagnosis of femoral hernia and review

•The rarity of these finding as a important differential diagnosis in groin and femoral hernia repair.•Diagnosis made at operative field with possibility of preoperative diagnosis with duplex ultrasonography.•The treatment well illustrated in figures by the simple ligation of the feeding vessel.•Great review about the venous aneurysms and the treatment options.

IntroductionVenous aneurysms are unusual clinical entities that might be difficult to diagnose and usually appear as an asymptomatic incidental finding on physical examination or imaging study and discovered only during the surgical exploration. They are important differential diagnosis of groin and other subcutaneous mass.Presentation of caseWe report a case of a 67-years-old woman who had a groin mass misdiagnosed as femoral hernia, which was subsequently diagnose as great saphena vein aneurysm in the intraoperative set and treated with ligature and resection.DiscussionIn conclusion, venous aneurysms of the superficial system are lesions that are important differential diagnosis of groin and other subcutaneous mass.ConclusionDiagnosis is readily available by duplex ultrasonography; however, in most cases, the diagnosis is done only in the operative field.
