title: Liver Trapping of (99m)Tc Macroaggregated Albumin During Ventilation/Perfusion Scintigraphy in a Patient With Superior Vena Cava Stenosis as Demonstrated by SPECT/CT.
abstract: A 50-year-old woman presented to our institution with a 1-day history of right posterior thoracic pain and dyspnea. She had a previous history of conservative resection of a high-grade basal-like infiltrating ductal carcinoma of the right breast 2 years before, subsequently treated by chemotherapy and radiotherapy. A ventilation and perfusion (VQ) scintigraphy performed for suspected pulmonary embolism showed an abnormal deposition of (99m)Tc macroaggregated albumin ((99m)Tc-MAA) in the left lobe of the liver. This unusual finding prompted additional imaging that demonstrated a superior vena cava stenosis.
