Clinical presentation and diagnostic evaluation of pheochromocytoma : case series and literature review
BACKGROUND: Pheochromocytoma is a rare tumor frequently overlooked mainly due to the wide range of its clinical presentation, which may vary from entirely untypical signs and symptoms to life-threatening complications.
METHODS: The present study aims to present a case series recently treated in our center, with emphasis placed on patients' specific characteristics, clinical presentation and diagnostic evaluation. Relevant literature and current guidelines are being briefly reviewed to summarize screening for pheochromocytoma and appropriate diagnostic procedures.
RESULTS: While the classic symptoms include headache, palpitations and sweating with permanent or paroxysmal hypertension, a wide range of clinical manifestations may be attributed to pheochromocytoma. The initial screening test is measurement of plasma or 24-hour urine metanephrine levels. Abdominal computerized tomography with intravenous contrast infusion is suggested as the imaging examination of choice, whereas magnetic resonance imaging should be preferred over CT in exceptional cases. 123I-metaiodobenzylguanidine scintigraphy is particularly useful for establishing the diagnosis of pheochromocytoma and should be further applied to detect or exclude possible metastatic lesions.
CONCLUSION: Early diagnosis of pheochromocytoma is of great significance not only because it represents a curable form of secondary hypertension, but also because it is often related to familial syndromes, malignancy or metastatic disease. Physicians need to be familiar with relevant clinical manifestations and diagnostic steps to raise clinical suspiction of pheochromocytoma and establish a timely diagnosis.
