Tc-99m macro aggregated albumin scintigraphy – indications other than pulmonary embolism: A pictorial essay
A 27-years-old known cirrhotic female patient, who underwent peritoneal venous shunt (PVS) 6 months ago, was referred for the evaluation of shunt patency. There was no history of malena or hemetemesis. On examination, her abdomen was very tense and mildly tender with positive fluid thrill. Dilated cutaneous veins (caput medusae) were visible around the umbilicus. From this clinical presentation, it was evident that her PVS was not functioning properly. It was confirmed by Tc-99m MAA shunt scintigraphy and site of shunt obstruction was localized by a simple and non-invasive nuclear medicine protocol [Figures and ].
