Clinical History
This is a 44-year-old female with known lesions in the
left and right lober of her liver by CT, Ultrasound, and
MRI. This examination is requested to corrolate with the
Sulfur Colloid SPECT exam so the known lesions can
be identified as tumor vs. cavernous hemangioma.
Technique
Utilizing 31 millicuries of 99m Tc04, the patient's red
blood cells were tagged and multiple SPECT images
of the abdomen were obtained. Transverse, sagittal,
coronal and 3D volume rendered images were
generated. Comparison is made from an outside
previous RBC liver scan and 99m Tc-Sulfur Colloid
scan.
Findings
Today's study demonstrates a cold mass lesion in the
right lobe of the liver, which demonstrates increased
uptake of the labeled RBC's primarily along the periphery
of this lesion. This is similar in appearance to the patient's
previous outside RBC exam. An additional focal area
of increased uptake of the labeled red blood cells is
seen in the left side of the abdomen, most likely in the
left lobe of the liver, medial to the spleen. Both the cold
and hot lesions correspond to the lesions seen on the
Sulfur Colloid Liver SPECT exam.
Impressions
Mass lesions are identified in both the right and left
lobes of the liver. The lesion in the right lober of the
liver is cold on both the Sulfur Colloid SPECT exam and
the RBC SPECT exam and appears to be a tumor. The
lesion in the left lobe of the liver is cold on the Sulfur
Colloid SPECT exam but is hot on the RBC SPECT
exam. This lesion appears to be a cavernous
hemangioma. There are also numerous lesions seen
around the large mess in the right lobe of the liver
which appear to be cavernous hemangioma's.
