Thyroid uptake and scintigraphy using 99mTc-pertechnetate has proven to be more advantageous than with 131I-iodide, since the images have better quality, the procedure is faster and the patient is submitted to a lower radiation dose. ⋯ The assessment of thyroid structure and function using 99mTc-pertechnetate is a simple, fast and efficient method, which could easily become a part of the routine studies in nuclear medicine laboratories.

Review Case Reports
Acute abdomen due to late retroperitoneal extravasation from a femoral venous catheter in a newborn.
The use of parenteral nutrition via a central venous catheter is a common practice in the neonatal intensive care setting. Extravasation of the infusate leading to an acute abdomen is a complication that has only rarely been documented. This report describes the case of a premature infant with a femoral catheter placed in the inferior vena cava, who developed an acute abdomen as a result of late retroperitoneal extravasation of parenteral nutrition. ⋯ A pre-term infant receiving total parenteral nutrition via a femoral venous catheter developed an acute abdomen five days after the catheter placement. Extravascular catheter migration to the retroperitoneal space and extravasation of the infusate was diagnosed by contrast injection. Withdrawal of the catheter was followed by prompt cessation of the signs and full recovery from the acute abdomen, without the need for surgery. A review of the literature is presented, emphasizing the clinical and therapeutic aspects of this unusual complication from femoral venous catheterization and parenteral nutrition.
