Summary
This case study highlights a rare primary hepatic pheochromocytoma causing severe hypertension. Surgical removal of this adrenal tumor led to normalized blood pressure and catecholamine levels.
Area of Science:
- Endocrinology
- Oncology
- Radiology
Background:
- Pheochromocytomas are rare tumors, typically adrenal, causing hypertension.
- Extra-adrenal pheochromocytomas can occur along sympathetic chains.
- Primary hepatic pheochromocytoma is an exceptionally rare presentation.
Observation:
- A 24-year-old male presented with severe hypertension.
- Imaging revealed a liver mass (segment 8) with high vascularity.
- Iodine 131-metaiodobenzylguanidine scintigraphy confirmed hepatic localization.
Findings:
- Multi-modal imaging (ultrasound, CT, MRI, angiography) characterized the hepatic tumor.
- Elevated catecholamines confirmed in hepatic venous sampling, with normal adrenal sampling.
- Surgical resection of the hepatic pheochromocytoma was successful.
Implications:
- This case underscores the importance of considering rare extra-adrenal sites for pheochromocytomas.
- Accurate diagnosis and localization are crucial for managing hypertension caused by these tumors.
- Complete surgical resection offers a potentially curative treatment for hepatic pheochromocytoma.
