The baseline CT's showed lypmhadenopathy in the left inguinal node and the left iliac fossa. The PET Scan showed increased metabolism in both of these lesions, however the Gallium scan only showed uptake in the inguinal lesion. The Bone scan was normal.
The CT scan, Gallium scan and Bone scan were repeated at 2 months (the PET scan was not repeated). The CT scan showed interval decrease in size of both the inguinal node and the iliac fossa node. The Gallium scan showed no uptake in the inguinal node. The Bone scan was normal.
The CT scan, PET scan, and Gallium scan were repeated at 3 months (the Bone scan was not repeated). The CT scan showed interval increase in size of both the the inguinal node and the iliac fossa node. There is also development of left common femoral lymphadenopathy. The PET scan showed no metabolism in the left iliac node. The left inguinal node is smaller in size but the SUV is still elevated at 3.0. The PET scan also detected a lesion anterior to the bladder with an SUV of 2.5. The Gallium scan showed resolution of the left inguinal node.
The CT scan, PET scan and Gallium scan were repeated about five years post initial diagnosis. The CT scan showed bilateral supraclavicular lymphadenopathy as well as mediastinal lymphadenopathy. In addition, there is moderate abdominal lymphadenopathy with the largest being in the left periaortic region. There is also multiple low-density lesions in the spleen. The pelvic lymph node has not changed in size since the last exam. The PET scan correlates to the same areas reported by the CT scan. The Gallium scan does not demonstrate any lymphadenopathy and is again not correlating to the PET and CT scans.
The CT scan and PET scan were repeated 48 days later following aggressive chemotherapy prior to autologous bone marrow transplantation. The CT scan showed marked interval decrease in supraclavicular, mediastinal and periaortic lymphadenopathy. There was also a slight interval decrease in the splenic lesion, consistent with favorable response to therapy. The PET scan correlates with the CT results and the Gallium scan was not repeated.
