ULTRASONOGRAPHY – IMPORTANT INFORMATION FOR THE THYROID SURGEON
Neck
ultrasonography (US) is the most widely used imaging modality to evaluate
thyroid disease. US should be used either as the initial imaging examination or
following detection of a thyroid abnormality on physical examination or on
another imaging modality (such as computed tomography [CT], magnetic resonance
imaging [MRI] or fluorodeoxyglucose-positron emission tomography [FDG-PET]). A
dedicated thyroid US should provide the surgeon the following important
information:
1.Characterization
of the thyroid parenchyma (homogenous / heterogenous)
2.Size of
each thyroid lobe (length, width and height) and isthmus
3.Presence,
size and location of pyramoid lobe
4.Location,
size and echomorphological characteristics of thyroid nodules and eventual extension
into the superior mediastinum (retrosternal extension)
5.Evaluation
of cervical lymph nodes. Pathologically enlarged lymph nodes should be
described in detail (size and location within the compartments [levels] of the
neck)
6.Concomittant
pathological enlargement of parathyroid gland(-s) should be described, if
present.
