A rare functioning mediastinal paraganglioma caused refractory hypertension in a young woman. Diagnostic imaging and biochemical tests confirmed the diagnosis, leading to successful surgical resection of the tumor.

Area of Science:

  • Endocrinology
  • Oncology
  • Cardiology

Background:

  • Mediastinal paragangliomas are rare neuroendocrine tumors arising from the paraganglion system.
  • Functioning paragangliomas secrete catecholamines, leading to significant clinical manifestations.

Observation:

  • A 26-year-old woman presented with a 6-month history of therapy-resistant hypertension.
  • Elevated urinary catecholamines and plasma noradrenaline levels were detected.
  • Imaging revealed a posterior mediastinal mass with characteristic mIBG scan uptake.

Findings:

  • Surgical resection of the 5 cm mediastinal lesion was performed.
  • Histological examination confirmed the diagnosis of paraganglioma.
  • This case highlights the diagnostic challenges and clinical presentation of functioning mediastinal paraganglioma.

Implications:

  • Early diagnosis and surgical intervention are crucial for managing mediastinal paragangliomas.
  • This case underscores the importance of considering rare endocrine tumors in patients with refractory hypertension.
  • Further research into the molecular mechanisms and optimal treatment strategies for these rare tumors is warranted.
