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.
