Simultaneous occurrence of multiple meningiomas of the spine appearing at different neuroaxial levels is extremely rare event. We present the scintigraphic findings of incidentally detected multiple meningiomas of the spine on 68 Ga-DOTATATE PET/CT during the evaluation of a patient with pulmonary carcinoid tumor. These scintigraphic findings could result in a "false-positive" interpretation by exhibiting highly increased uptake similar to that of metastases of neuroendocrine neoplasm.

- An oncological patient was found to have a lipomatous tumor that could easily be mistaken for a cancer due to its intense FDG activity.
- Sequential PET/CT scans showed changes in FDG uptake, indicating that the tumor was benign rather than malignant.
- This careful monitoring allowed for a reduction in treatment intensity, ultimately avoiding the need for major surgery.
Article Synopsis
- A 64-year-old woman with breast cancer had an FDG PET/CT scan that showed increased activity in enlarged axillary lymph nodes, raising concerns for cancer spread.
- Further testing (histopathology) determined that the lymph nodes had a rare benign condition that looked like cancer, known as progressive transformation of germinal centers.
- This case highlights the importance for nuclear medicine physicians to recognize this benign condition as a potential false-positive in PET scans, particularly in breast cancer evaluations.
An 84-year-old man underwent 18 F-prostate-specific membrane antigen (PSMA) PET/CT for staging of a newly diagnosed prostate adenocarcinoma. PET/CT revealed high 18 F-PSMA uptake in a thigh mass, which was initially suspected for a metastasis. Histopathology revealed a rare entity of spindle cell lipoma, which should be added to the reported list of neoplasms that can show "false-positive" PSMA uptake during evaluation of patients with prostate carcinoma representing a potential interpretative pitfall.

However, uptake is not completely specific, and "false-positive" uptake in nonthyroidal tumors have rarely been reported. Herein, we present a case of incidentally detected neuroendocrine tumor showing high radioiodine uptake initially suspected to be thyroid metastasis.
