Another imaging modality, which is ultrasound elastography, is also useful in diagnosing thyroid malignancy especially for follicular thyroid cancer. However, it is limited by the presence of adequate amount of normal tissue around the lesion, calcified shell around a nodule, cystic nodules, coalescent nodules. [16]
No focal lesion or micro-calcifications. b Non-enhanced CT scan obtained as part of PET/CT examination shows a heterogeneous, large, relatively dense anterior mediastinal mass (white arrow) with peripheral calcification (arrowheads). Thyroid gland has normal CT appearance with no abnormal FDG uptake (not shown). [1]
The external iliac lymph nodes are lymph nodes, from eight to ten in number, that lie along the external iliac vessels.. They are arranged in three groups, one on the lateral, another on the medial, and a third on the anterior aspect of the vessels; the third group is, however, sometimes absent.

Risk factors for developing liver abscess can be due to infection, post-procedural infection and metastasis such as primary liver tumours, liver metastasis, biliary procedures, biliary injuries, biliary tract disease, appendicitis, and diverticulitis.
However, a benign tumor is not benign in the usual sense; the name merely specifies that it is not "malignant", i.e. cancerous. While benign tumors usually do not pose a serious health risk, they can be harmful or fatal. [2] Many types of benign tumors have the potential to become cancerous through a process known as tumor progression. For this ...
