RESUMO
May-Thurner syndrome is the result of compression of the left common iliac vein between the right common iliac artery and the overlying vertebrae. In this case report, we describe an 11-year-old boy presenting with swelling of the left lower extremity. An iliac MR venography showed compression of the left proximal iliac vein between the vertebra and the left iliac artery. In surgery, it was seen that the left common iliac vein was connected to the postero-inferior part of the inferior vena cava, and it was compressed between the right common iliac artery and the columna vertebralis, which was inconsistent with the radiological findings. An interposition of the great saphenous vein graft between the left common iliac vein and the inferior vena cava was made, with a successful outcome. Our case is interesting in that it showed inconsistent findings between the radiological images and surgery.

Unilateral nevoid telangiectasia (UNT) is characterized by the dermatomal distribution of telangiectasia, which are distributed unilaterally and frequently found in C3-C4 or the trigeminal dermatomal areas. It may be congenital or acquired and has a 2:1 female: male ratio. Several theories where developed in order to explain its etiopathogenesis. The most widely accepted is the one which establishes its probable association with an increase in estrogen levels. Its incidence is unknown, although it's probably subdiagnosed and more frequent than previously recognized. We present two pediatric cases of UNT followed at our instution during the past year.
