The function of chromogranin A (CGA) is reviewed, and the radioimmunometric determination of plasma CGA was evaluated as a marker of pheochromocytoma using a comparison of pheochromocytoma patients immediately before surgery (group P, n=25, 635+/-451 ng/ml) with other groups of patients, i.e. pheochromocytoma patients approximately 1 year after removal of tumor (group PP, n=13, 69+/-33 ng/ml), ...

Introduction: Situs inversus totalis is an uncommon anomaly which exist a complete transposition of organs and it's occasionally associated with congenital heart diseases, such as tetralogy of fallot. Pheochromocytoma is a rare neuroendocrine tumor with an annual incidence of 2-8 cases per million people and for years has been studied its relationship with the hypoxic pathway. Case Report: A 29...

We report the case of a 65 year old man with recent onset of insulin requiring diabetes mellitus, frequent attacks of anginal chest pain, paroxysmal hypertension poorly controlled with three medications, hyperlipidemia, and mild renal insufficiency. The patient was found to have pheochromocytoma of the left adrenal gland, resection of which resulted in total resolution of diabetes, hyperte...

Abstract Background Reversible Cerebral Vasoconstriction Syndrome is a condition of transient cerebral vascular spasms, which usually presents with recurrent thunderclap headaches and recovers within 3 months. Several probable triggers underlying factors, such as sex hormones, vasoactive drugs, head trauma or surgery, tumors, have been implicated. Case presentation In this paper, we present 53-...

BACKGROUND: Biochemical testing for pheochromocytoma by measurement of fractionated plasma metanephrines is limited by false positive rates of up to 18% in people without known genetic predisposition to the disease. The plasma normetanephrine fraction is responsible for most false positives and plasma normetanephrine increases with age. The objective of this study was to determine if we could i...

Pheochromocytomas (rare catecholamine-producing neuroendocrine tumors) have many different manifestations, and complications can occasionally include myocardial infarction and cardiomyopathy. In a majority of cases, cardiomyopathy reverses following medical or surgical treatment of the pheochromocytoma. We report a case of a 28-year-old male patient with preoperative diagnosis of pheochromocyto...
