text: Yo, check it out, we got a Tc pertechnetate scintigraphy in the mix,
  64-year-old woman, mediastinal cystic mass, let's fix.
  After gastrectomy, we gotta find that gastric mucosa residue,
  Esophagectomy, gastric pull-up, esophageal cancer, it's true.
  Postoperative leakage, had to ablate the pull-up, colon reconstruction,
  But oral realimentation got her feelin' that mediastinal pain, no seduction.
  Trachea be drippin' that brownish discharge, it's kinda gross,
  Thinkin' 'bout that residual gastric pouch, let's diagnose.
  SPECT/CT showin' increased tracer uptake, that's the clue,
  Biopsy confirmed it, we got that gastric mucosa, it's true.
