Localisation of chyle leak with Tc-99m colloid (SPECT/CT)

Case contributed by Dr Brendon Friesen

Presentation

Oesophagectomy for oesophageal adenocarcinoma - complicated by persistent left chylothorax

Patient Data

Age: 75
Gender: Male

Technique:

Planar imaging acquired 2 hours following intradermal administration of Tc-99m antimony colloid between the toes of the left foot (not shown). Then a delayed SPECT-CT was obtained (shown above).

Findings:

Abnormal accumulation of radiotracer in the mediastinum, immediately anteromedial to the descending thoracic aorta at the level of the right pulmonary artery. The radiotracer also accumulates in a left pleural loculated chylothorax (lateral to descending thoracic aorta).

Case Discussion

Tc-99m antimony colloid with SPECT/CT can be used to localise the site of a post-operative chyle leak, which can be helpful for surgical planning.
