LOCALIZATION OF PHEOCHROMOCYTOMA BY SELECTIVE CAVAL CATHETERIZATION

Selective Venous Catheterization for the Localization of Phosphaturic Mesenchymal Tumors

Tumor-induced osteomalacia (TIO) is characterized by renal phosphate wasting, hypophosphatemia, and aberrant vitamin D(3) metabolism and is caused by fibroblast growth factor 23 (FGF-23)-producing mesenchymal tumors, which are often difficult to locate. We investigated the utility of selective venous sampling in tumor localization. The primary endpoint was identification of the FGF-23 concentra...

Localization of mediastinal paragangliomas (pheochromocytoma).

Diagnosis and localization of pheochromocytoma.

This Hypertension Grand Rounds shows how applying new clinical laboratory techniques helped to diagnose pheochromocytoma in a difficult case. In the setting of long-standing, sustained hypertension, the patient had a hypertensive paroxysm during anesthesia induction for surgery, leading to suspicion of a pheochromocytoma. Conventional testing, including CT scanning and fractionated urinary meta...

Catecholamines in the localization of pheochromocytoma.

Pheochromocytoma: Tips on Diagnosis and Localization

6 New Technologies in Diabetes Mellitus Catecholamine-secreting tumors that arise from chromaffin cells of the adrenal medulla and the sympathetic ganglia are referred to as pheochromocytomas and extra-adrenal catecholamine-secreting paragangliomas (extra-adrenal pheochromocytomas), respectively. Because the tumors have similar clinical presentations and are treated with similar approaches, man...
