18F-FDG Avid in Uterine Leiomyoma: A Case Report
Chiewvit S Mail

            The author presents a case of 18F-FDG avid in uterine leiomyoma. A 32-year old female had Hodgkin’s lymphoma
stage IVb (the primary lesions at bilateral supraclavicular, right paratracheal, subcarina, intraabdominal, bilateral iliac
lymph nodes with liver, spleen and bone marrow involvement). She was sent for 18F-FDG PET/CT scan for detection of active
lymphoma after chemotherapy treatment. The positive finding was hypermetabolic well defined round shape-enhanced lesion
at posterior fundus. The SUV max (maximum value of Standard uptake value) was 6.3 and 2.0 x 1.9 CM in size. This lesion
on CT finding is compatible with uterine leiomyoma. There is no other area of abnormal activity in the other body parts in the
scan finding. After the PET/CT study, the patient was in remission of disease with no treatment.The planning is for follow-up
CT. The knowledge of normal variation or false positive finding of 18F-FDG PET scan in order to get the exact diagnosis can
dramatically alter the clinical course or plan of treatment.
