Case 83: Hyperthyroidism | Thyrotoxicosis || Doppler

, ,


Clinical Features:

A 35-year-old female patient came with 

- Midline neck swelling

- Weight loss

- Diarrhoea


Ultrasound Features:

- Diffusely enlarged thyroid gland with heterogeneous echotexture.

- Grossly increased parenchymal vascularity forming the ‘Thyroid Inferno’ as well as grossly increased flow velocities in bilateral thyroid arteries.


Ultrasound Diagnosis:

Hyperthyroid Goitre


Ultrasound Images:



Diffuse thyromegaly with heterogeneous parenchyma


Thickened isthmus with high parenchymal vascularity


Enlarged inhomogeneous right lobe


Enlarged inhomogeneous left lobe


Very high flow velocities in the right inferior thyroid artery 


Very high flow velocities in the right superior thyroid artery 


Very high flow velocities in the left inferior thyroid artery 


Very high flow velocities in the left superior thyroid artery 


Increased parenchymal vascularity

Case 78: Solitary Solid Thyroid Nodule

,

 

Ultrasound Features:

- A small irregular hypoechoic solid nodule is noted at the postero-superior aspect of the right thyroid lobe.

- Color Doppler shows low-resistant internal vascularity.


Ultrasound Diagnosis:

Solitary solid thyroid nodule (Rt)


Ultrasound Images:

Case 34: Autoimmune Thyroiditis

, ,


Autoimmune Thyroiditis


Clinical Features:

  • Asymptomatic patient.
  • Anti-thyroid Antibody - Positive.


Ultrasound Findings:

  • Enlarged thyroid lobes.
  • Inhomogeneous parenchyma with diffuse cystic appearance.
  • No lymphadenopathy at present.
  • Doppler: Vascularity was borderline at present.
  • Rt lobe arteries: PSV 20-30cm/s.
  • Lt lobe arteries: PSV 20-25cm/s.












Case 04: Thyroid Nodule Ultrasound

,

Introduction:

Complex nodules are very common in thyroid gland and most of them are benign. Use of color Doppler along with 3D ultrasound aid in further evaluation.

Clinical Features:

23 years old female patient was sent for suspected thyromegaly.

Ultrasound Findings:

Right lobe is mildly enlarged with relatively normal left lobe & isthmus.
A well defined complex nodule containing both solid & cystic components (Predominantly cystic), is noted at the mid region of the right lobe.
Color Doppler shows a peripheral arterial supply with 28cm/s of PSV and 0.69 of RI. No internal vascularity.
Rest of the thyoid gland appears uniform.
No evidence of cervical lymphadenopathy or underlying muscle abnormality.

Images:






Features highly suggestive of:

Enlarged right lobe with complex nodule which is most likely benign.
However, FNAC correlation was advised for further evaluation.
