Melanoma Whole body FDG-PET scan:
Fifty year old male with a lump under his right arm. History of left shoulder melanoma one year ago with excision.
Negative
Negative
Negative
Positive
The right axillary lump noted on the history is
markedly hypermetabolic by FDG-PET and is worrisome
for a neoplasm. Given the history of melanoma, suspect
this represents a recurrence mild activity is noted
within the left shoulder and lower lumbar spine
which is felt to be degenerative in nature when
given that the activity is significatnly less than
seen in the right axilla. Mild activity is also
noted within the left hemi thorax posteriorly. Most
likely on the basis of pleural thickening.
No abnormal intracranial activity is identified. However, contrast enhanced MRI would be more sensitive in detecting small metastic
deposits. |
