From: Thyroid gland cutaneous fistula secondary to a migratory fish bone: a case report
Preoperative computed tomography findings. Contrast-enhanced (A) axial and (B) sagittal computed tomography reveal a bone-density needle-shaped foreign body sticking out anteroinferior from the esophageal wall, penetrating through the superior pole of the left thyroid lobe, and extending nearly to the anterior cervical skin. The foreign body is surrounded by a low density area, suggesting abscess formation.
