Named after Austrian anatomist , who first detailed it in 1902, the tubercle is an embryological remnant formed at the point where the lateral thyroid process (ultimobranchial body) fuses with the median thyroid anlage.

Consequently, medullary thyroid carcinoma, which arises from C-cells, frequently manifests within or adjacent to the TZ. tubercle of zuckerkandl

A large TZ may be misdiagnosed as a suspicious nodule. Confirm continuity with the lobe. Named after Austrian anatomist , who first detailed
