Acute axillosubclavian vein thrombosis (Paget-Schroetter syndrome) detected by Tc-99m MAA during pulmonary perfusion scintigraphy.

The authors describe a 24-year-old man who reported the sudden onset of dyspnea and swelling of his left upper arm. An area of increased activity in the left axillosubclavian region evident on pulmonary perfusion scintigraphy with Tc-99m MAA suggested Paget-Schroetter syndrome (primary deep venous thrombosis of the upper extremity).
