18F-FDG PET/CT helps in unmasking the great mimicker: A case of neurosarcoidosis with isolated involvement of the spinal cord

Publication date: May–June 2018 Source:Revista Española de Medicina Nuclear e Imagen Molecular (English Edition), Volume 37, Issue 3 Author(s): A. Gholamrezanezhad, L. Mehta A 36 year-old male with no significant past medical history presented with lower extremity numbness, gait instability, and urinary and bowel retention of 4 weeks onset. Spine MRI revealed diffuse oedema of cervicothoracic spinal cord with several solid enhancing intramedullary lesions, suggestive of metastases. The 18F-FDG PET/CT performed to identify the primary malignancy demonstrated mild hypermetabolic foci within the cervicothoracic cord, as well as a mildly hypermetabolic bilateral hilar lymphadenopathy and a mildly hypermetabolic pulmonary nodule, suggestive of sarcoidosis versus metastasis. The diagnosis of sarcoidosis was supported by identifying non-caseating granuloma in the biopsy of the pulmonary nodule. The patient responded well to steroid-therapy, with the symptoms being resolved within 3 weeks.
