ABSTRACT
INTRODUCTION: Pheochromocytoma is rare tumor with a highly variable clinical presentation. This report provides clinical picture, efficiency of diagnostics and treatment of pheochromocytoma in 8-years in the endocrinological center in Wroclaw. MATERIAL AND METHODS: The records of 37 patients with pheochromocytoma were identified, who were treated in 2000-2007 in the Department of Endocrinology, Diabetology and Isotope Treatment in Wroclaw. There were 23 women (age 23-75 year) and 14 men (age 17-74). We studied frequency of clinical signs, usefulness of diagnostic methods and efficacy of treatment. RESULTS: The duration of the clinical history ranged from 2 months to 16 years. The most frequent symptoms were: hypertension paroxysmal and constant, palpitations, headache, sweating and anxiety. The most sensitive diagnostic method was increased concentration of urinary metanephrine in 24-hour urine. Computed tomography was the most widely used method for tumor localization. Adrenal pheochromocytoma was detecting by CT in all patients, predominated in right adrenal, in 1 case in urinary bladder. Surgery caused remission of hypertension in 59%, improvement in 26.8%, and no changes in 13.9% of patients. Malignancy was reported in 2 cases, 1 woman died after surgery. MEN 2A occur in 21.6%. CONCLUSIONS: The diagnosis of pheochromocytma is usually made after long duration of the disease. The study confirms that clinical presentation of pheochromocytoma is variable and nonspecific, this finding makes the diagnosis very difficult. The most typical symptom is paroxysmal hypertension, which is present only in 40%, other symptoms are nonspecific. The measurement of 24-hour urinary metanephrines was the best indicator. CT was almost always successful in localizing the tumor. Patients with pheochromocytoma should be consider for other endocrine diseases especially medullary carcinoma, primary hyperparathyroidism and other component of MEN 2A.

A case of 19-year-old male with idiopathic diabetes insipidus diagnosed 9 years ago. 1.5 years from the onset of the disease vision disturbances, neurologic deficiencies and symptoms of hypopituitarism showed up. MRI examination revealed an advanced hypophyseal and pineal gland tumor--germinoma. Total regression was achieved with radio- and chemotherapy. For 7 years from the end of treatment patient has not declared any complains except for vision disturbances and hypopituitarism has been substituted successfully. The case puts on the necessity of a strict endocrinologic and radiologic follow-up in patients with idiopathic diabetes insipidus due to the possibility of existing potentially curable disease ie. intracranial tumor.
