RESUMO
ABSTRACT: A 35-year-old woman underwent 18 F-FDG PET/CT 2 months after a radical hysterectomy for uterine cervical cancer. An apparent FDG uptake was observed in an oval-shaped mass with an attached surgical clip in the right paracolic gutter. A similar non-FDG-avid mass with a clip was observed in the left. In this case, ovarian transposition had also been performed with metallic clips placed on both sides of the paracolic gutters. The increased FDG uptake in the right paracolic gutter was interpreted as physiological uptake in the right transposed ovary, not metastasis. Recognizing the possibility of FDG uptake in transposed ovaries is important.

ABSTRACT: A 77-year-old man with parkinsonism was referred to the department of neurology for further examination. Cardiac 123I-MIBG scintigraphy unexpectedly showed strong uptake in the left shoulder, suggestive of MIBG-avid tumors including paraganglioma. MRI revealed multiple nodules suggestive of lymphoma. A biopsy was performed, which led to the pathological diagnosis of diffuse large B-cell lymphoma. Cardiac MIBG scintigraphy sometimes shows unexpected findings outside the mediastinum. In addition, lymphoma should also be added to the list of differential diagnoses for MIBG-positive tumors.
