Abstract
INTRODUCTION AND IMPORTANCE Phaeochromocytomas are neuroendocrine neoplasms arising from chromaffin cells of the adrenal medulla and are known as intra-adrenal paragangliomas. On the contrary, paragangliomas are non-epithelial neuroendocrine neoplasms that produce other peptide hormones such as norepinephrine, epinephrine, and dopamine. In a setting with limited resources, such a condition may result in inaccurate diagnosis and treatment, which may lose a patient life if left untreated. In addition, PPGLs present a surgical challenge to many surgeons who are not thoroughly prepared. CASE PRESENTATION We describe a case of extra-adrenal paraganglioma in a 27-year-old female who presented with symptoms of heartbeat awareness for almost a year and abdominal swelling for three months. Physical examination revealed a palpable mass around the umbilicus. Abdominal pelvic CT scan revealed a well-circumscribed mass in the central retroperitoneum displacing the IVC laterally and abdominal aorta medially with no invasion of surrounding structures. Results for pheochromocytoma workup showed elevated levels of 24-h urine Vanillylmandelic acid (VMA), and 24-h metanephrine excretion. Laparotomy through extended midline incision was done with successful excision of the tumor. The blood pressure, which was initially high normalized after surgery. DISCUSSION The diagnosis of a malignant EAP is commonly made based on recurrence and the development of metastasis to lymph nodes or to other organs. Our patient presented with similar symptoms as pheochromocytoma. Compared to the commonly stated 10 % risk for pheochromocytomas, people with EAPs have been observed to have a 20 % to 50 % incidence of malignancy. EAPs account for at least 15 % of adult and 30 % of pediatric pheochromocytomas and are frequently found in the Zuckerkandl organ. Pheochromocytoma symptoms may manifest asymptomatically in patients with EAPs, or they may occur because of compression of nearby tissues. Surgical excision of the tumor is always the best option in managing EAP. CONCLUSION Extra-adrenal paragangliomas can be successfully managed surgically, provided there is a multidisciplinary team, and the tumor location is well recognized and can reduce the chance of tumor metastasis.

Abstract
BACKGROUND Surgery is the treatment of choice for pheochromocytoma. However, this surgery carries a risk of hemodynamic instability (HDI). The aim of this study was to report complications associated with this procedure, to identify risk factors for HDI during surgery, and its impact on postoperative outcomes. METHODS The charts of all patients who underwent adrenalectomy for pheochromocytoma in two academic centers between 2006 and 2020 were retrospectively reviewed. The primary outcome was HDI defined by a systolic blood pressure >160 mmHg or a mean blood pressure <60 mmHg intraoperatively. The secondary outcomes of interest were the total duration of HDI, the occurrence of intraoperative arrhythmia, perioperative cardiovascular events, and postoperative complications. RESULTS 205 patients were included. HDI occurred intraoperatively in 155 patients (75.6%) but only 6 (3.2%) experienced arrhythmia. Thirty-eight postoperative complications were reported (18.6%) but only nine were ≥3 according to Clavien-Dindo (4.4%). There were 10 postoperative cardiovascular events (5.7%). Patients with intraoperative HDI had higher rates of postoperative complications (21.3% vs 10%; P = .07), major postoperative complications (5.8% vs 0%; P = .12) and cardiovascular events (6.5% vs 0%; P = .12). Factors associated with intraoperative HDI in univariate analysis were age (OR = 8.14; P = .006), high blood pressure preoperatively (OR = 2.16; P = .04), tumor size (OR = 15.83; P = .0001), and urinary normetanephrine level (OR = 9.33; P = .04). DISCUSSION In multidisciplinary centers, the overall morbidity of adrenalectomy for pheochromocytoma is low. HDI during adrenalectomy for pheochromocytoma is highly prevalent but rarely associated with major cardiovascular events. There might be a link between HDI and postoperative cardiovascular events.

Abstract
Bladder Paraganglioma is a rare type of bladder tumor (0.06%). It is typically benign and the most common symptoms are hematuria, hypertension and headache. About 14% of these tumors are malign and consequently radio and chemoresistants. Therefore, surgery is the mainstay of treatment. As they are likely to recur and to metastize lifelong follow-up is required. The authors report a rare case of a 53 years old man with hematuria and a previous history of micturition syncope who was diagnosed with bladder lesion. During the transurethral ressection of bladder he became severely hypertensive. Plasma metanephrines, and urinary vanillylmandelic acid, were still high and the exams suggested residual tumor. The patient underwent radical cistoprostatectomy. After 4 years of follow-up the patient remains disease free.

Abstract
In ectopic ACTH-secreting pheochromocytoma, combined ACTH-driven hypercortisolemia and hypercatecholaminemia are serious conditions, which can be fatal if not diagnosed and managed appropriately, especially when glucocorticoid-driven positive feedback is suggested with a high ACTH/cortisol ratio. A 46-year-old man presented with headache, rapid weight loss, hyperhidrosis, severe hypertension and hyperglycemia without typical Cushingoid appearance. Endocrinological examinations demonstrated elevated plasma and urine catecholamines, serum cortisol and plasma ACTH. Moreover, his ACTH/cortisol ratio and catecholamine levels were extremely high, suggesting catecholamine-dominant ACTH-secreting pheochromocytoma. Computed tomography revealed a large right adrenal tumor. 18F-FDG positron emission tomography showed uptake in the area of the adrenal tumor, while 123I-metaiodobenzylguanidine scintigraphy showed no accumulation. His plasma ACTH level paradoxically became elevated after a dexamethasone suppression test. After metyrapone administration, not only serum cortisol but also plasma ACTH levels were exponentially decreased almost in parallel, suggesting a glucocorticoid-driven positive-feedback regulation in this rapidly exacerbated ectopic ACTH-producing pheochromocytoma. Interestingly enough, plasma catecholamine levels were also decreased by metyrapone, although they remained extremely high. He became severely dehydrated due to hypoadrenalism requiring hydrocortisone supplementation. His clinical signs and symptoms were improved, and right adrenalectomy was performed uneventfully, resulting in complete remission of pheochromocytoma and Cushing's syndrome. A glucocorticoid-driven positive-feedback regulation in this ectopic ACTH-secreting pheochromocytoma created a vicious cycle with rapid exacerbation of both hypercortisolemia and hypercatecholaminemia with extremely elevated plasma ACTH level. Metyrapone was clinically effective to stop this vicious cycle; nonetheless, great care must be taken to avoid hypoadrenalism especially when hypercatecholaminemia remained.

Abstract
Bladder paragangliomas are rare and account for less than 0.05% of all bladder tumours. They can present as incidental findings without any clinical symptoms. Due to the non-specific nature, they are often not part of the urologists differential diagnoses. Pre-operative suspicion and management are essential to reduce anaesthetic risk.
Introduction Non-urothelial tumours are rare and account for less than 5% of all bladder tumours. Bladder paragangliomas also known as extra-adrenal pheochromocytomas are of the non-urothelial subgroup. We present an unusual case of asymptomatic bladder paraganglioma. Case report A 77 year old lady presented with acute abdominal pain was found to have an incidental enhancing nodule in the bladder. During cystoscopy and transurethral resection the patient experienced significant fluctuations in blood pressure that required anaesthetic adjustments. Review of histology confirmed a diagnosis of bladder paraganglioma. Discussion Most bladder paraganglioma cases present with sympathomimetic related symptoms and microscopic haematuria but our patient was asymptomatic which resulted in inadequate pre-operative optimisation and high anaesthetic risk. Majority of paragangliomas are benign but there is a 20-40% chance of malignancy. The management options will predominantly depend on whether disease is localised, regional, metastatic or recurrent in nature. Conclusion Due to the non-specific nature of disease, variability of presentations and rare incidence, bladder paragangliomas are often not part of the urologists’ differential diagnoses. In our opinion, establishing guidelines should assist to achieve a balance between anaesthetic risks, cystoscopy and follow up.

Abstract
Pheochromocytomas are rare tumors that present a diagnostic challenge in developing countries. They occur in the adrenal gland and as paragangliomas along the sympathetic chain. Clinical features are usually those of sustained or paroxysmal hypertension and complications thereof. Surgical extirpation remains the mainstay of treatment and is greatly facilitated by accurate pre-operative tumor localization. Pre-operative medical management with antihypertensive medication has led to significant reductions in peri-operative mortality. Determination of malignancy is difficult in the absence of obvious metastases. We present a case of left adrenal phechromocytoma that was stabilized. Adrenalectomy had a good outcome and the patient has so far been followed up for a year.

Abstract
Adrenal tumors comprise a broad spectrum of benign and malignant neoplasms and include functional adrenal adenomas, pheochromocytomas, primary adrenocortical carcinoma, and adrenal metastases. Percutaneous ablative approaches that have been described and used in the treatment of adrenal tumors include percutaneous radiofrequency ablation, cryoablation, microwave ablation, and chemical ablation. Local tumor ablation in the adrenal gland presents unique challenges, secondary to the adrenal gland's unique anatomic and physiological features. The results of clinical series employing percutaneous ablative techniques in the treatment of adrenal tumors are reviewed in this article. Clinical and technical considerations unique to ablation in the adrenal gland are presented, including approaches commonly used in our practices, and risks and potential complications are discussed.

Abstract
BACKGROUND Surgery on pheochromocytoma carries a risk for hemodynamic (HD) instability. The aim of this study was to identify preoperative risk factors for intraoperative HD instability. In addition, efficacy of pretreatment with the alpha-adrenergic receptor (alpha) antagonists phenoxybenzamine (PXB) and doxazosin (DOX) was compared with respect to reduction of intraoperative HD instability. METHODS Seventy-three patients operated in Erasmus Medical Center between 1995 and 2007 were included. Parameters studied were catecholamine type and concentration, tumor diameter, mean arterial pressure (MAP) before and after (MAP(alpha)) pretreatment with alpha-antagonist, postural fall in blood pressure (BP) after pretreatment, type of alpha-blockade, type of operation, and presence of a familial polytumor syndrome. HD instability was assessed by measuring the number and time period MAP was below 60 mm Hg and systolic BP (SBP) was above 160 mm Hg. RESULTS A correlation was found between the intraoperative time periods of SBP above 160 mm Hg and plasma norepinephrine levels (r = 0.23; P < 0.05), tumor diameter (r = 0.36; P < 0.01), and postural BP fall (r = 0.30; P < 0.05). MAP at presentation and after alpha-blockade above 100 mm Hg (BP, 130/85 mm Hg) was related to more and longer episodes with a SBP above 160 mm Hg (P < 0.01). Type of operation or alpha-blockade and presence of a familial polytumor syndrome were not related to intraoperative HD instability. Postoperative MAP was lower in the DOX group than in the PXB group (P < 0.05). CONCLUSION Risk factors for HD instability during surgery for pheochromocytoma include a high plasma NE concentration, larger tumor size, more profound postural BP fall after alpha-blockade, and a MAP above 100 mm Hg (130/85 mm Hg). Efficacy for preventing HD instability was identical for PXB and DOX.

Abstract
BACKGROUND The enhancement of metaiodobenzylguanidine single photon emission computed tomography (MIBG SPECT) imaging through the addition of CT images fused with SPECT data (coregistered MIBG SPECT/CT imaging) is new technology that allows direct correlation of anatomical and functional information. We hypothesized that MIBG SPECT/CT imaging would provide additional information and improve diagnostic confidence for the radiological localization of a pheochromocytoma, in particular for patients at high risk of multifocal or recurrent disease. METHODS A retrospective study of all patients investigated by MIBG SPECT/CT at our institution from 2006 to 2008 for a suspected pheochromocytoma was performed. Each case was compared with conventional radiological investigations to determine whether MIBG SPECT/CT was able to improve diagnostic confidence and provide additional diagnostic information compared with conventional imaging alone. RESULTS Twenty-two patients had MIBG SPECT/CT imaging for a suspected pheochromocytoma. Fourteen patients had positive MIBG SPECT/CT imaging results correlating with imaging by CT or magnetic resonance imaging in all cases. In six cases, MIBG SPECT/CT provided additional information that altered the original radiological diagnosis. Five patients with a pheochromocytoma-associated germline mutation had multifocal disease excluded by MIBG SPECT/CT. Patients without a germline mutation that had positive biochemistry and a solitary lesion with conventional imaging had no diagnostic improvement with MIBG SPECT/CT imaging. CONCLUSIONS MIBG SPECT/CT fusion imaging is a sensitive and specific radiological imaging tool for patients suspected to have pheochromocytoma. The particular strengths of MIBG SPECT/CT are detection of local recurrence, small extra-adrenal pheochromocytomas, multifocal tumors, or the presence of metastatic disease.

Abstract
Autoimmune polyendocrine syndrome type II (APS-II) is the most common immunoendocrinopathy syndrome. APS-II is defined by the development of two or more of the following entities: primary adrenal insufficiency (Addison's disease), Graves' disease, type 1A diabetes mellitus, autoimmune thyroiditis, primary hypogonadism, celiac disease, and myasthenia gravis. Other frequent clinical findings are vitiligo, alopecia, pernicious anemia and/or serositis. Primary adrenal insufficiency in these patients affects the adrenal cortex, which is destroyed by autoantibodies against 21-hydroxylase. Unlike other causes of adrenal insufficiency (infectious diseases, infiltrative diseases, bleeding, tumors), the adrenal medulla is not involved. Pheochromocytomas are tumors arising from the chromaffin cells of the sympathetic nervous system in the adrenal medulla. The clinical symptoms of these tumors vary from isolated hypertension or hypertension accompanied by paroxysmal episodes -including the classical triad of headache, palpitations and diaphoresis-to potentially serious manifestations such as acute pulmonary edema, arrhythmias and sudden death. Nevertheless, up to 40% of affected patients are asymptomatic. We present the case of a patient diagnosed with APS-II who developed a pheochromocytoma. In this patient, the adrenal gland cortex was atrophied and the tumor was attached to the adrenal medulla. This coexistence of endocrinopathies, with no etiologic connection, is a surprising finding, which has not previously been described in the current literature.

Abstract
We report the case of a patient who presented to the emergency with the common symptoms of chest pain and dyspnoea and who was subsequently found to have the rare diagnosis of a phaeochromocytoma. We highlight the need to maintain a high index of suspicion of the various differential diagnoses in any case presentation and the importance of trusting clinical intuition. We comment on the benefit of the use of emergency ultrasound.

Abstract
Extra-adrenal pheochromocytomas (EAPs) may arise in any portion of the paraganglion system, though they most commonly occur below the diaphragm, frequently in the organ of Zuckerkandl. EAPs probably represent at least 15% of adult and 30% of childhood pheochromocytomas, as opposed to the traditional teaching that 10% of all pheochromocytomas are at extra-adrenal sites. They may be malignant in up to 40% of the cases, though conflicting data add to the uncertainty of this point. Patients with EAPs may present with headache, palpitations, sweating, or hypertension. A small percent of patients may also be asymptomatic at presentation due to nonfunctional tumors. The diagnosis is confirmed by demonstrating elevated blood and urine levels of catecholamines and their metabolites. Imaging studies to evaluate for EAPs include CT, MRI, and (131)I-labelled metaiodobenzylguanidine scintigraphy. Preoperative pharmacologic preparation, attentive intraoperative monitoring, and aggressive surgical therapy have important roles in achieving successful outcomes. Recent reports suggest that a laparoscopic approach, along with intraoperative ultrasound, can safely remove these tumors. EAPs recur and metastasize more often than their adrenal counterparts, making lifelong follow-up essential.
