A 25 -Year-Old Woman Complaining of a Swelling on the Front

A 25 -year-old woman complaining of a swelling on the front of the neck and breathlessness visited her physician. On examination, a small, solitary swelling of firm consistency was found to the left of the midline of the neck below the thyroid cartilage of the larynx. The swelling was not attached to the skin but moved upward on swallowing. About 2 weeks previously the swelling had suddenly increased in size and had become tender to touch; following this increase in size the patient became breathless.
-The following statements concerning this case would suggest a diagnosis of adenoma of the thyroid gland except which?

A) The pretracheal layer of deep cervical fascia binds the thyroid gland to the larynx, which moves upward on swallowing.
B) Each lobe of the thyroid gland is closely related to the sides of the trachea.
C) The isthmus of the thyroid gland was found to cross in front of the third, fourth, and fifth rings of the trachea.
D) The sudden increase in the size of the swelling can be explained by a hemorrhage into the adenoma.
E) The swelling was located superficial to the left sternothyroid muscle.
F) The breathlessness was caused by the adenoma pressing on the trachea, partially occluding the lumen.
