Fig 39 : Dynamic and static scintigraphy in a 27 year old man with a liver abscess (A,B), which was aspirated (C,D); the study exemplifies how an abscess, if critically situated, may embarass circulation. 99m Tc phytate was injected into a malleolar vein, which lies outside the field view. (A) as the radio-pharmaceutical ascends, iliac vein and the inital segment of the inferior vena cava (I.V.C.) are well visualised; thereafter, flowing through the I.V.C. appears impeded and a collateral channel is evident. (B) static scan, anterior view, shows an irregularly shaped liver with a "cold area" (arrow) in the inferior portion of the right lobe and compensatory hypertrophy of the left lobe; spleen in normal. (C) 15 days after aspirationof 650 ml. anchovy sauce material, the I.V.C exhibits a normal lumen with free flow; collaterals are not seen (D) static liver scan at this point shows considerable resolution of the cold area.
