Thyroid neoplasm The first step in diagnosing a thyroid neoplasm is a physical exam of the neck area. If any abnormalities exist, a doctor needs to be consulted. A family doctor may conduct blood tests, an ultrasound, and nuclear scan as steps to a diagnosis. The results from these tests are then read by an endocrinologist who will determine what problems the thyroid has. Hyperthyroidism and hypothyroidism are two conditions that often arise from an abnormally functioning thyroid gland. These occur when the thyroid is producing too much or too little thyroid hormone respectively. Thyroid nodules are a major presentation of thyroid
Computed tomography of the thyroid 70 % of cases, the ectopic thyroid is the only functional thyroid tissue present in the body (Fig. 18). Ectopic thyroid tissue lateral to the orthotopic midline location is rare. The exact anatomical definition of this rare entity is debated in the literature. To avoid confusion, some authors define a lateral neck ectopic thyroid as any thyroid tissue superficial to the strap muscles with no midline continuity. The majority of lateral thyroid ectopia cases have been reported as lesions closely related to the strap muscles. There are few reported cases of ectopic lateral thyroid tissue in the submandibular region, jugulodigastric
