Paraganglioma is a very rare tumor and it can be diagnosed with catecholamine hypersecretion which induce a paroxysmal hypertension [1-3]. When it is ruptured by traumatic injury and the patient has a hemodynamic instability due to bleeding, preoperative evaluation and medical therapy are not impossible in acute phase [4,5]. Sometimes even though the patient has hypovolemic shock, catecholamine can mask the symptom of hypotension which confuses a clinician to make an adequate decision. Unfortunately, there is no definitive guideline of treatment for traumatic ruptured paraganglioma. Nevertheless, paroxysmal hypertension during shock and enhanced mass give us a clue for suspect of paraganglioma rupture in this case; it is difficult to distinguish paraganglioma rupture from retroperitoneal hematoma because of paroxysmal hypertension and enhanced ruptured mass.
A 73-year-old female was admitted to trauma center after rolling down on the stairs which induced abdominal contusion. She was suffering from abdominal pain. Initial blood pressure was 63/50 mmHg and pulse rate was 46/min. In an hour after resuscitation, blood pressure became too high (241/114 mmHg) and fluctuated without any intervention. On the computed tomography scan, a huge mass with enhanced lesions with extravasation and adjacent hemorrhages were observed in the left retroperitoneum (Figures 1-3). At the first time, emergency operation was considered to control bleeding but not performed because paroxysmal hypertension existed. The rupture of endocrine tumor secreting catecholamine was suspected. After laboratory evaluation with an endocrinologist and a radiologist, the mass turned out to be a paraganglioma.
After preoperative evaluation for paraganglioma, the medication for adrenal suppression was given to the patient for 14 days in the intensive care unit, then elective surgery was performed 1 month later. On the pathologic report, the specimen was identified as a paraganglioma with low risk of malignancy (pheochromocytoma of the Adrenal Gland Scaled Score 0) (Figures 4-6).
