Thyroid Abnormality - Pyramidal Lobe

A common anatomical variation seen in as high as half anatomical dissections and more frequently in men than in women.[1]


A third lobe, of conical shape, called the pyramidal lobe, frequently arises from the upper part of the isthmus, or from the adjacent portion of either lobe, but most commonly the left, and ascends as far as the hyoid bone. It is occasionally quite detached, or may be divided into two or more parts.
