Difference Between Diffuma Stratum And Nodusa Stratum?
What’s the difference between goitre nodosa and difusa? From the size, boundaries, surface mass, and other physical examination?
Good evening, thanks for the question
Struma is a swelling of the neck due to enlargement of the thyroid gland due to abnormalities of the thyroid gland.
The terms diffusa and nodusa refer to changes in anatomic shape. In diffuse thyroid enlargement of the thyroid gland occurs bilaterally or completely so that the entire neck may be swollen. The surface is usually flat and the enlargement limit is rather difficult to determine.
Whereas in the nodal goitre, one or several lumps will be found which cause the surface of the thyroid gland to be uneven. The location of the lump is usually asymmetrical and the size limit can be determined. If there is more than one lump then it is called a multinodular goitre.
Besides based on anatomy, goitre can also be divided into toxic and non-toxic. In toxic struma excessive thyroid hormone release occurs so that the levels in the blood become high and cause symptoms of hyperthyroidism in sufferers. Whereas in non-toxic goitre only enlargement or bumps without accompanied by hyperthyroid conditions.
In addition to physical examination, there are several investigations that can help diagnose the cause of the enlarged condition in the thyroid gland. These tests include thyroid hormone examination, thyroid ultrasound, thyroid scan, and fine needle biopsy.
That's all, hope you can help. Wassalam, Dr. Farah
