Nuances to provide ideas for radiologic diagnosis in primary spinal paragangliomas: report of two cases

Abstract

Spinal paragangliomas are rarely-observed neuroendocrine benign tumors in the extra-adrenal paraganglionic system. Primary spinal involvement is even rarer. Radiologic differential diagnosis is not easy. This paper presents 2 lumbar paraganglioma cases and focuses on nuances to provide ideas for radiological differential diagnosis.
