title: Somatostatin receptor-positive granulomatous inflammation mimicking as meningioma on simultaneous PET/MRI.
abstract: Positron imaging with radiolabeled synthetic somatostatin receptor analogs such as Ga DOTATATE (Gallium-68-1,4,7,10-tetraazacyclododecane-N,N',N″,N‴-tetra acetic acid-DPhe1,Tyr3-octreotate) is used for diagnosis and target volume delineation of intracranial meningiomas. We report a case of a somatostatin receptor-positive extra-axial necrotizing granulomatous inflammation mimicking as meningioma on simultaneous Ga DOTATATE PET/MRI. This case illustrates a Ga DOTATATE-positive granuloma bearing a striking resemblance to meningioma.
