technetium-tc-99m-gluceptate and Abscess

Although many radiopharmaceuticals are "targeted" for specific tissues or organs, they may be incorporated into nonspecific sites to the extent that they are readily diffusible. There may be local hyperemia with "leaky" neovascularity or capillaries and perhaps also diminished lymphatic or venous removal from the affected area. Two cases are reported in which abscesses were visualized serendipitously. One was visualized on a Tc-99m MDP bone scan following nephrectomy, the other on a patient with a pelvic abscess and nonvisualized left kidney but with enhancement of the rim of a large pelvic abscess.

Although suprarenal abscess in a newborn is rare, a prompt diagnosis is essential for proper patient management. The findings obtained with Tc-99m glucoheptonate renal imaging in a newborn with a right adrenal abscess are reported. A radionuclide renal imaging sequence over a 15-hour period demonstrated a "rim sign" which can be used to suggest the diagnosis. Radionuclide and ultrasound imaging of neonatal adrenal masses is discussed.
