Fdg Pet/Ct In Disseminated Intracranial And Intramedullary Spinal Cord Tuberculomas

A 54-year-old woman was referred because of dizziness with fatigue for 2 months. MRI of the head and spinal cord revealed multiple ring or homogeneous enhancing nodules in the brain and spinal cord, concerning for metastases. FDG PET/CT showed multiple hypermetabolic nodules in the brain and spinal cord corresponding to the gadolinium-enhanced nodules and diffuse FDG uptake in the bilateral lower lobes of the lungs. Chest high-resolution CT showed diffuse, bilateral miliary opacities, most predominant in the lower lobes. The imaging findings and results of cerebrospinal fluid analysis were consistent with disseminated central nervous system tuberculomas with miliary pulmonary tuberculosis.
