A 22-year-old woman with rapidly progressing metastatic paraganglioma due to hereditary paraganglioma-pheochromocytoma syndrome from an SDHB mutation, who recurred after neoadjuvant chemotherapy, was found to be MIBG avid. She was treated with 2 I-MIBG treatments and concurrent sunitinib, achieving a complete response. She was in full remission for 9 months before developing bone metastases.

Pheochromocytomas and paragangliomas (PPGLs) are rare neuroendocrine tumors derived from chromaffin cells, with 80-85% originating in the adrenal medulla and 15-20% from extra-adrenal chromaffin tissues (paragangliomas). Approximately 30-40% of PPGLs have a hereditary component, making them one of the most genetically predisposed tumor types. Recent advances in genetic research have classified PPGLs into three molecular clusters: pseudohypoxia-related, kinase-signaling, and -signaling pathway variants.

Arterial hypertension in young adults, which includes patients between 19 and 40 years of age, has been increasing in recent years and is associated with a significantly higher risk of target organ damage and short-term mortality. It has been reported that up to 10% of these cases are due to a potentially reversible secondary cause, mainly of endocrine (primary aldosteronism, Cushing's syndrome, and pheochromocytoma/paraganglioma), renal (renovascular hypertension due to fibromuscular dysplasia and renal parenchymal disease), or cardiac (coarctation of the aorta) origin. It is recommended to rule out a secondary cause of high blood pressure (BP) in those patients with early onset of grade 2 or 3 hypertension, acute worsening of previously controlled hypertension, resistant hypertension, hypertensive emergency, severe target organ damage disproportionate to the grade of hypertension, or in the face of clinical or biochemical characteristics suggestive of a secondary cause of hypertension.

Pheochromocytoma and paraganglioma (PPGL) are rare chromaffin-cell tumors producing adrenaline and/or noradrenaline, or solely dopamine. A 52-year-old man presenting with hypertension (141/79 mm Hg) and weight loss (10 kg in 6 months) was admitted to our hospital. Computed tomography revealed a massive right adrenal mass (150 mm) with partial necrosis, accompanied by multiple liver nodules.

Carotid body tumors (CBTs) are rare head and neck paragangliomas that arise from the carotid body chemoreceptor at the common carotid bifurcation. These neoplasms are generally benign, slow-growing, nonsecreting, and well-vascularized. Metastasis occurs in ~5% of cases.

Background: Pheochromocytomas (PCCs) are rare neuroendocrine catecholamine (CA)-secreting tumours that originate from chromaffin tissue and can produce and store CAs. Unexpected PCCs pose a serious threat to the perioperative safety of patients and a considerable challenge to anaesthesiologists because of the risks of fatal hypertensive crises and other stresses.
Case Presentation: A 37-year-old woman who was scheduled for tonsillectomy and palatopharyngoplasty under general anaesthesia experienced a malignant cardiovascular event after induction, which was characterized mainly by a sharp increase in heart rate and blood pressure, ultimately leading to cardiac arrest and the occurrence of secondary long QT syndrome.
