Aggressive posterior paraganglioma presenting with generalized weakness, anemia, hypertension, and weight loss: A case report.

Paragangliomas (PGLs) are rare neuroendocrine tumors that originate from chromaffin cells in the extra-adrenal autonomic nervous system's ganglia. The diagnosis of PGL is made based on clinical characteristics, biochemical tests, imaging, functional studies, and pathology reports. Catecholamines and chromogranin A levels should be evaluated prior to biopsy or surgical excision. We present a case of aggressive PGL in a 55-year-old woman presented with weakness, blurred vision, hypertension, and weight loss.
