A rare hepatic paraganglioma causing hypertension was surgically removed. The patient recovered well, with hypertension resolving after the tumor resection, highlighting surgical management for this rare condition.

Area of Science:

  • Endocrinology
  • Surgical Oncology
  • Radiology

Background:

  • Paragangliomas are rare neuroendocrine tumors arising from extra-adrenal chromaffin cells.
  • Primary hepatic paragangliomas are exceptionally rare, often presenting with vague symptoms or complications of hormone excess.
  • Hypertension is a key clinical manifestation in functioning paragangliomas due to catecholamine secretion.

Observation:

  • A patient presented with a functioning hepatic paraganglioma, a rare liver tumor.
  • Computed tomography revealed a highly vascular lesion in segment 6 of the liver, measuring 6 x 5.5 cm.
  • The tumor was identified as the cause of the patient's hypertension.

Findings:

  • Surgical resection via right hemihepatectomy was performed for the hepatic paraganglioma.

  • The patient experienced an uneventful recovery following the surgery.
  • Hypertension resolved completely after the tumor removal, confirming the functional nature of the paraganglioma.

    • Implications:

    • Surgical management is effective for functioning hepatic paragangliomas, leading to resolution of associated hypertension.
    • Long-term follow-up is crucial for detecting potential recurrence or metastasis of this rare malignant tumor.
    • Understanding the imaging characteristics and therapeutic principles is vital for managing these uncommon neuroendocrine neoplasms.
