PET/CT SCAN SKULL BASE TO MIDTHIGH
Findings: There is widespread hypermetabolic osseous metastatic disease with associated osteoblastic changes which are most prominent in the spine and pelvis. Since the previous study there has been an increase in hypermetabolic activity in metastases in the sternum, the scapulae, the thoracic spine, the lumbar spine, the sacrum, bilateral ribs, the femurs and the iliac bones. Peak SUV values in a lesion in the left iliac bone now measure up to 10.4 compared to a 6.6 on the previous study (4-8-10). Many of the lesions previously seen in the pelvis appear to have a larger hypermetabolic component than previously seen. There are no areas of soft tissue metastatic disease in the neck.
No pulmonary lesions are seen. There is no adenopathy in the neck or chest. There is no evidence of metastatic disease in the liver, spleen, pancreas, adrenal glands or kidneys. No adenopathy is seen in the abdomen or pelvis. There is hypermetabolic soft tissue density in the right side of the pelvis measuring 37 X 52 mm with SUV values of 12.6. This has an appearance suggesting an enlarged right ovary. The metabolic activity in the right ovary is significantly greater than left ovary where there are peak SUV values of 5.0. The right ovarian metabolic activity is nonspecific and may be related to a physiological activity. However, the possibility of ovarian metastatic disease cannot be excluded. Metabolic activity in the left ovary is in the physiological range.
Previous Study: 4-8-10
