Introduction: Iodine-123-meta-iodobenzylguanidine ((123)I-MIBG) imaging is currently a mainstay in the evaluation of many neuroendocrine tumors, especially neuroblastoma. (123)I-MIBG imaging has several limitations that can be overcome by the use of a PET agent. (18)F-MFBG is a positron emission tomography (PET) analog of MIBG that may allow for single-day, high-resolution quantitative imaging. We conducted a first-in-human study of (18)F-MFBG PET imaging to evaluate the safety, feasibility, pharmacokinetics, and dosimetry of (18)F-MFBG in neuroendocrine tumors (NETs)...

Pheochromocytoma associated with inferior vena cava (IVC) thrombosis is very rare. A 27-year-old female presented with right flank pain and hypertensive urgency. Contrast-enhanced CT abdomen and gadolinium-contrast MRI abdomen revealed right adrenal mass suspicious of malignancy with invasion and compression to the right IVC wall along with IVC thrombus extending from the level of renal veins to the level of confluence with hepatic veins. Her routine laboratory investigations including 24-hour urine fractionated metanephrines, vanillylmandelic acid, and cortisol were normal...

BACKGROUND: Adrenal adenomas are benign tumors often discovered incidentally, and >70% are hormonally inactive. The remaining subset may produce excess aldosterone, cortisol, or catecholamine. Perioperative outcomes after adrenalectomy for such "hormonally active" tumors remain unclear. This study examines in-hospital outcomes after unilateral adrenalectomy for hormonally active tumors. METHODS: A retrospective review was performed using the Nationwide Inpatient Sample (2006-2011) to identify patients undergoing unilateral adrenalectomy for hormonally active or inactive tumors...

BACKGROUND: Adrenal incidentalomas are increasingly diagnosed and include a wide spectrum of lesions from benign adenomas to secreting or malignant lesions. The aim of the present study is to report a large single-institution experience of patients undergoing surgery for adrenal incidentaloma with particular attention to their diagnosis and post-operative course and the evolution of surgical practice over time. METHODS: From 1993 to 2013, 274 patients underwent adrenalectomy for incidentaloma...

OBJECTIVE: The entity of primary mandibular paraganglioma (PGL) is not well accepted within the head and neck. Mandibular PGLs hitherto reported in literature are malignant metastatic lesions, mostly from a pheochromocytoma. METHODS: We report a case of mandibular lytic lesion in a young female with multifocal PGLs but no family history of PGLs. We also performed a literature search to identify published cases of mandibular PGL. RESULTS: Lack of established criteria for malignancy in a PGL made diagnosis and treatment challenging...

INTRODUCTION: Pheochromocytomas are rare catecholamine-producing neuroendocrine tumors. They are surgically curable but can be lethal if remain undiagnosed. We report a patient earlier diagnosed with malignant hyperthermia but later found to have pheochromocytoma on autopsy. CASE REPORT: After a preprocedural pain block for elective right shoulder arthroscopy, a 53-year-old hypertensive white man developed chest pain. In the operating room, he had increased blood pressure...

We describe a 15-year-old boy with a huge bilateral adrenal pheochromocytoma that had a de novo germline mutation in the succinate dehydrogenase subunit B (SDHB) gene. F-FDG PET/CT revealed bilateral metabolically active large masses in the adrenal glands and the activated brown adipose tissues. The I-MIBG scintigraphic findings revealed only a mild accumulation of MIBG in the right adrenal mass, but a high uptake in the left adrenal mass. Thus, F-FDG PET/CT imaging may be more effective than I-MIBG scintigraphy for the evaluation of pheochromocytomas that are associated with highly malignant characteristics resulting from mutations of the SDHB gene...

Adrenal tumours are rare and their management is challenging. Every patient presenting with adrenal mass or symptoms of hormones hypersecretion should be investigated. The two important questions to be answered are : 1. Is the tumour secreting ? Is the tumour malignant or not ? A complete endocrine work-up and a nativ CT-scan may usually answer these two questions but have to be interpreted by specialists in a multidisciplinary team setting. The decisions about managements of adrenal pathologies do follow international guidelines which are regularly updated...

We report a surgical case of retroperitoneal paraganglioma. A paraganglioma is a catecholamine-producing tumor originating in the chromaffin cells of the sympathetic ganglion. It is a kind of pheochromocytoma which occurs on the outside of the adrenal gland. The patient was a 72 year old male with a history of hypertension and a pacemaker implantation. A mass in the ventral side of the right iliopsoas muscle was detected during a routine contrasting computed tomography (CT) examination for checking his pacemaker...

INTRODUCTION: Adrenal neoplasms comprise about 10% of all tumours affecting this organ and constitute a significant, at first diagnostic and subsequently therapeutic, problem, especially since a relatively high proportion of neoplastic lesions are asymptomatic. The number of diagnosed metastases to adrenal glands is increasing. Surgical treatment involves both open surgery as well as laparoscopy. MATERIAL AND METHODS: There were 235 adrenalectomies performed at our centre due to various indications over the past four years...

INTRODUCTION: Although few studies have demonstrated utility of (18) F- fluoro-2-deoxy-d-glucose positron emission tomography/computerised tomography ((18) F-FDG PET/CT) in benign pheochromocytoma/paragangliomas (PCC/PGLs), there limited data on factors predicting the FDG uptake in PCC/PGL. METHODS: The study was conducted at a tertiary health care centre. In addition to the routine investigations, all patients (n = 96) with PCC/PGL were evaluated with (18) F-FDGPET/CT and majority (n = 78) underwent (131) I-metaiodobenzyl guanidine ((131) I-MIBG) scintigraphy...

Pheochromocytomas and paragangliomas (PCC/PGL) are tumors in the adrenal medulla and extra adrenal sites, respectively. About a quarter are metastatic, often with a long latency period. Some PCC/PGL are defined as clinically aggressive given extensive local invasion into adjacent normal tissue. These tumors, like metastatic PCC/PGL, cannot be surgically cured and patients can have continued secretion of excessive catecholamines with all related sequelae. For patients with metastatic or aggressive tumors, treatment options are limited...

REVIEW
Vijaya Sarathi
The "rule of 10" used to describe pheochromocytoma/paragangliomas (PCC/PGLs) has been challenged. However, recent studies suggested that pediatric PCC/PGLs may follow a pattern. Hence, we reviewed the available literature to verify the same. We searched PubMed, Scopus, ProQuest, and Google Scholar for studies describing the genotype and/or phenotype characteristics of pediatric PCC/PGL cohorts published after 2000 in English language and those with sample size more than 35 were included in this review. Pediatric PCC/PGLs were malignant in 10%, synchronous bilateral in 20%, extra-adrenal in 30%, among which, 30% were extra-abdominal and familial in 40%...

Open adrenalectomy still plays an important role in adrenal surgery. A review of the current literature has been carried out to discuss the main indication to open adrenalectomy with regards to the main adrenal pathologies. The authors underlined the role of open adrenalectomy on the basis of personal experience and a literature review. Indication to open adrenalectomy for adrenal cysts, myelolipomas, pheochromocytomas, metastases, adrenocortical carcinomas and tumour recurrences were analysed and discussed...

Von-Hippel Lindau (VHL) disease is a rare, inherited multicystic disorder that is characterized by several benign and malignant neoplasms (1). Classically, the disease manifests itself in a broad spectrum including: renal cell carcinomas, intracranial and spinal hemangioblastomas, endolymphatic sac tumors, renal and pancreatic cysts, and pheochromocytomas. Another important, but commonly forgotten manifestation is the cystadenoma of the rete testis.

Adrenal tumors can vary from a benign adrenocortical adenoma with no hormonal secretion to a secretory adrenocortical malignancy (adrenocortical carcinoma) or a hormone-secreting tumor of the adrenal medulla (pheochromocytoma). Currently, laparoscopic adrenalectomy is regarded as the preferred surgical approach for the management of most adrenal surgical disorders, although there are no prospective randomized trials comparing this technique with open adrenalectomy. However, widespread adoption of robotic technology has positioned robotic adrenalectomy as an option in some medical centers...

Pheochromocytomas and paragangliomas are tumors that occur in characteristic locations and are commonly detected on imaging studies. A correct diagnosis is important because of differences in associated neoplasms, risk for malignancy, and need for genetic testing. In addition, associated complications, including death, can be avoided if appropriately recognized and treated. Here, we report a rare case of an extra-adrenal paraganglioma of the organ of Zuckerkandl.

Alfred King-Yin Lam
The fourth edition of the World Health Organization (WHO) classification of endocrine tumours contains substantial new findings for the adrenal tumours. The tumours are presented in two chapters labelled as "Tumours of the adrenal cortex" and "Tumours of the adrenal medulla and extra-adrenal paraganglia." Tumours of the adrenal cortex are classified as cortical carcinoma, cortical adenoma, sex cord stromal tumours, adenomatoid tumour, mesenchymal and stromal tumours (myelolipoma and schwannoma), haematological tumours, and secondary tumours...
