My sister has a pheochromocytoma. i've had pancreatitis, cholecystitis, ulcers and a kidney stone, preeclampsia, cluster headaches.could this be pheo?

Pheochromocytoma: Pheochromocytoma is a rare tumor of the adrenal gland that secretes hormones that cause elevated blood pressure. While some cases are hereditary and run in families or are associated with certain syndromes, most cases are sporadic. The other symptoms you describe are not typical for pheochromocytome, but i would recommend seeing your doctor if you are worried.

Unlikely: Pheochromocytoma is characterized by episodic malignant hypertension. There are syndromes that link thyroid cancer and hyperparathyroidism to pheos - men - multiple endocrine neoplasias. Kidney stones, headaches, and preeclampsia could be related, but there is no relationship to cholecystitis or pancreatitis.

No: In 1961 Sipple described a combination of a pheochromocytoma, medullary thyroid carcinoma and parathyroid adenoma, the MEN syndrome. Unless the kidney stones are related to parathyroid disease, your symptoms are GB stones and secondary pancreatitis. You do not have the classic signs of a Pheo which would have to be confirmed on abdominal scan and show presence of serum epinephrine derivatives .
