[Non-specific abnormality (so called "hot spot") on 99mTc-phytate liver scintigraphy of patients associated with superior vena caval syndrome (author's transl)].
We have recently observed two patients with superior vena caval syndrome who showed a unique abnormality, so called "Hot Spot", on the 99mTc-phytate liver scintigraphy. This phenomenon seems to be related to the collateral venous circulation. It is supposed that its manifestation depends on the degree of venous dilatation of the chest and abdominal wall.
