Nonfunctional preaortic paraganglioma: report of one case.

A case of nonfunctional benign preaortic paraganglioma is reported. The patient, a woman aged 50, complained of vague mesogastric pain irradiated posteriorly, occasional nausea and vomiting, related to a tender pulsatile mesogastric mass fixed to the posterior wall of the abdomen. Preoperative diagnostic examinations showed a severe anemia, a severe mechanical impairment of renal function as shown at IVP, a doubt of aortic aneurism at echography, not confirmed by selective arteriography. The mass was removed radically. The diagnosis of nature was only microscopic. Since from 15 days after surgery IVP improved significantly. At three months follow-up the patient is well with no sign of recurrence.
