Incidental finding of intense thyroid radiogallium activity during febrile illness
Abstract:
Two elderly adults presented with fever of undetermined origin. Radiogallium imaging showed intense concentration in the thyroid, without abnormal localization elsewhere. In the first case, a repeat radiogallium study performed three weeks later was within normal limits. The patient had 0% uptake of radioiodide, and no demonstrable iodine within the thyroid. This probably represented thyroiditis. In the second case, an elevated T4 (RIA) and borderline elevated T3 resin uptake suggested the "dumping phase" of thyroiditis. The two cases indicate that "benign" diseases of the thyroid can be associated with diffuse radiogallium concentration in the gland.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
