Summary
Pheochromocytomatosis, a rare recurrence of pheochromocytoma after surgery, requires high suspicion for diagnosis. This case demonstrates successful radio-guided surgery for widespread disease, emphasizing lifelong patient follow-up.
Area of Science:
- Endocrinology
- Surgical Oncology
- Rare Diseases
Background:
- Pheochromocytomatosis is a rare condition involving tumor cell seeding during adrenalectomy, often leading to delayed diagnosis.
- Recurrent pheochromocytoma symptoms, such as tachycardia and hypertension, can be challenging to diagnose, especially years after initial surgery.
Purpose of the Study:
- To present a case of pheochromocytomatosis with a 15-year diagnostic delay.
- To describe the successful management using radio-guided surgery.
- To review the literature on pheochromocytomatosis and its treatment.
Main Methods:
- Comprehensive hormonal evaluation to detect catecholamine overproduction.
- Imaging studies to identify recurrence sites.
- Radio-guided surgery utilizing 123I-labeled metaiodobenzylguanidine (MIBG) scintigraphy and a gamma probe for intra-operative localization.
Main Results:
- The patient presented with recurrent tachycardia and hypertension 15 years post-adrenalectomy.
- Diagnosis was confirmed via hormonal evaluation and imaging revealed recurrence in the spleen, omentum, and adrenal bed.
- Radio-guided surgery enabled complete resection and postoperative normalization of blood pressure and heart rate.
Conclusions:
- Lifelong follow-up and thorough endocrine evaluation are crucial for patients with a history of pheochromocytoma.
- Radio-guided surgery is a valuable tool for the intra-operative localization and treatment of pheochromocytomatosis.
