Abstract

A 62-year-old woman had progressively developing throbbing right neck pain for 1 year. The pain radiated to the right suboccipital area, sometimes accompanied by breathlessness. To rule out cancer, patient received FDG PET/CT, which showed an intraspinal cord intense FDG-avid calcified mass at the level of the first cervical spine, mimicking malignancy. MRI showed it effacing the medulla; surgery is probably a challenge. She received laminectomy with tumor removal; pathology showed psammomatous meningioma, World Health Organization grade I. This case suggests that benign spinal cord psammomatous meningioma with calcification may show high FDG uptake, mimicking malignancy.
