Question

Review the following scenario and answer the questions that follow: Radiology Report Mass adjacent to the Thyroid - Lt side on US done 5/5/10 EXAM: NECK W/WOUT CONTRAST 5/9/10 Initially scans were obtained throughout the neck without IV contrast. Following this, a bolus of IV contrast was given and rapid scans obtained through the region of interest in the neck, related to the left lobe of the thyroid. As demonstrated on the recent ultrasound, there is a well-defined oblong mass in the left neck measuring 2.2x3x1.8cm in size. This lies posterolateral to the left thyroid lobe and is predominately between the left common carotid artery, which is displaced posteromedially, and the left internal jugular vein, which is displaced laterally. No other adenopathy, and the remainder of the thyroid appears unremarkable. IMPRESSION: The mass appears to be extrinsic to the thyrold, possible even within the carotid sheath. The lesion appears to be relatively avascular. The differential diagnosis would include an unusually enlarged lymph node, a very atypical thyroid nodule, or a soft tissue tumor. The lesion is very easily accessible to needle blopsy and this would certainly be the easiest method of obtaining positive confirmation. This could be done using US guidance. 1. What type of radiologic test is described here? a. Ultrasound b. CT scans c. Pyelogram d. PET scan 2. Where is the mass located? a. Within the left lobe of the thyroid gland b. Between the left and rieht carotid arteries OFocus Steri

Answer 1

1) Option B.

CT scan.

CT scan help doctors to see inside the body without by cutting the body by using x ray and measuring from different direction.

2)The mass is located behind to the side of the left lobe of the Thyroid gland.
