From: Lymphoscintigraphy findings in patients with chylothorax: influence of biochemical parameters
A 29-year-old female with idiopathic chylothorax (bilateral). A continuous drainage tube was placed in the right pleural cavity, and laboratory analysis confirmed the right pleural effusion as a transudation. A The anterior (upper row) and posterior (lower row) planar images of the lymphoscintigraphy were acquired at 10 min–6 h. A localization site of lymphatic leakage was seen in the thoracic duct region (diaphragmatic level) at 1 h anterior (blue arrow). Radioactive tracer could be seen in the right thoracic drainage tube at 3 h anterior (red arrow). Visualization of radioactivity was observed in the left lower thorax and the right thorax at 3–6 h, suggesting a chylothorax on both sides (black arrows). B The thorax region SPECT/CT images (upper row CT image; middle row SPECT image; lower row hybrid SPECT/CT image) acquired at 3 h. The focal accumulation of radioactive tracer in the thoracic duct region had disappeared. Abnormal activity was seen in well-defined pleural effusion in the left lower thorax and the right thorax (thick red arrows)
