Abstract

Peritoneal radionuclide scan is an established imaging modality for evaluating peritoneopleural communications. In this case report, unusual mediastinal lymph node radiotracer uptake is seen in a patient with portal hypertension on peritoneal scintigraphy. This was suspected to be due to marked lymphatic enlargement from longstanding portal hypertension since childhood, permitting passage of the large Tc-99m MAA particle. The nodes were morphologically benign on CT. Mediastinal lymph node uptake on peritoneal scintigraphy is rare but should not raise undue clinical concern, particularly in a patient with chronic portal hypertension. Anatomic correlation with SPECT-CT can provide reassurance.
