Incidental Detection of Dual Spinal Meningiomas on 68 Ga-DOTATATE PET/CT Masquerading as Metastatic Disease in a Patient With Pulmonary Carcinoid Tumor.

ABSTRACT: 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. Nuclear medicine physicians should be aware of this potential pitfall in somatostatin receptor imaging to prevent misinterpretation.
