Abstract
Paraganglioma is a rare tumor arising from undifferentiated cells of the primitive neural crest. These tumors are most commonly found in the adrenal gland, other localisations are also possible. A 58-year-old woman who presented with history of left lumbar pain, headache, hypertension, palpitation and sweating was found to have a secreting left renal hilar pheochromocytoma. Radical excision of the tumor was therefore undertaken and her hypertension was controlled. From the case report and literature review, the authors suggest a diagnostic and therapeutic strategy for the management of ectopic localization of pheochromocytoma.
Highlights
Pheochromocytoma is a neuroendocrine tumor that usually develops upon the chromaffin cells of the adrenal medulla
Extraadrenal retroperitoneal paragangliomas arise from paraganglia, which are collections of specialized neural crest cells symmetrically distributed along the aorta in close association with the sympathetic chain
Following an observation of a renal hilar pheochromocytoma together with a review of the literature, this paper aims at reminding the clinical, therapeutic and histological features of this rare tumor
Summary
Pheochromocytoma is a neuroendocrine tumor that usually develops upon the chromaffin cells of the adrenal medulla. The usual signs are lumbar pain, hypertension associated with generalized symptoms due to raised catecholamines such as headache, blurred vision, heart palpitation and flushing. Case presentation The patient, a 58-year-old Moroccan housewife, suffered from a 5 year history of left lumbar pain, headache, hypertension, palpitation and sweating. Her blood pressure showed a 200/ 150 mmHg; she had a mass in the left subcostal region. Ultrasonography performed on the patient revealed a 6 cm size heterogeneous mass located in the region of the left renal hilum and an additional computed tomography of the abdomen demonstrated a dumbbell-shaped tumor, measuring 7.0 × 6.5 × 7.5 cm, in the left renal hilum and (page number not for citation purposes)
