Thyroid gland is the first endocrine gland to start developing in the embryo. The gland is well known for its developmental anomalies ranging from common and frequently seen to rare ones.
1.    The common anomalies include:
    a)    Persistence of a pyramidal lobe with or without the fibrous cord
    b)    Thyroglossal duct cyst
2.     The uncommon anomalies are:
    (a)     Failure of median lobe (isthmus) to fuse in the midline
    (b)     Absence of a part of the lateral lobe
    (c)     Ectopic thyroid
3.     Thyroid hemi agenesis with or without isthmus is a rare anomaly.

 An uncommon and clinically important developmental anomaly of the thyroid gland showing absent median lobe (isthmus) resulting in two separate lateral lobes, resembling two hockey sticks, is reported and discussed.
