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 malignant
pheochromocytoma has rarely been reported in English literature.
Conclusion: Here, we have reported a very rare case of pelvic metastatic malignant pheochromocytoma,
with a particular focus on sonoelastographic features.
