Sonoelastography for Pelvic Metastatic Malignant Pheochromocytoma: A Case Report

Abstract

Introduction: Pheochromocytoma are tumors arising from the chromaffin tissue located in the adrenal medulla, associated with typical symptoms and signs. Case Presentation: Occasionally, metastasis, defined as the presence of tumor cells at sites other than the original site, secondary to pheochromocytoma have been reported. Pelvic metastatic malig-nant pheochromocytoma has rarely been reported in English literature. Conclusion: Here, we have reported a very rare case of pelvic metastatic malignant pheochromocy-toma, with a particular focus on sonoelastographic features.
