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 2018Source: Revista Española de Medicina Nuclear e Imagen Molecular (English Edition), Volume 37, Issue 3Author(s): A. Gholamrezanezhad, L. MehtaAbstractA 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.ResumenDurante 4 semanas, un paciente varón de 36 años, sin historial clínico de relevancia, presentó entumecimiento en las extremidades inferiores, inestabilidad al andar, retención de orina y estreñimiento. La RM de la mèc)dula espinal mostró edema difuso en la mèc)dula dorsal cervicotorácica, así como imágenes de lesiones intramedulares sólidas indicativas de metástasis. Se realizó una 18F-FDG PET/TC para identificar la malignidad primaria de los focos hipermetabólicos de...
