Pheochromocytoma is a rare, but an important cause of surgically curable hypertension. Pheochromocytoma is a highly vascular tumor and not infrequently undergoes hemorrhagic necrosis and pseudocyst formation. Such cystic pheochromocytoma may be accompanied by shock and sepsis and commonly invade adjacent organs, in which cases its diagnosis and management may be difficult. Herein we present a case of adrenal cystic pheochromocytoma which was accompanied by sepsis and hypertension and mimicked pararenal abscess with a review of literatures.

The coronal sectional image of computerized tomography creates an image that is similar to an excretory urogram. It also provides more clearly delineated renal image and image of adjacent organs than an excretory urogram. Further more, the number, extent, and content of renal mats lesions used to discriminate density difference can be determined with relatively great accuracy. This image of computerized tomography is useful to understand and make a diagnosis of renal disease. Coronal sectional image of computerized tomography is more informative in evaluation of retroperitoneum space than conventional radiography. Recently we observed several cases of renal disease-renal cell ca, simple renal cyst, angiomyolipoma, retroperitoneal teratoma, pheochromocytoma, hydronephrosis which could be detected with coronal sectional image of computerized tomography.

Pheochromocytomas are catecholamine-producing tumors that typically cause hypertension. They are rare tumors that can pose problems in diagnosis and detection. Although they usually present classic symptoms, they can at times present symptoms that mimic other clinical conditions. Especially, children have fewer malignant tumors, non-extra-adrenal tumors, and tumors with greater bilaterality and multiplicity. The diagnosis of pheochromocytomas is based upon clinical suspicion and biochemical study. Radiologic localization is obtained before operation because of the variable location of this tumor. The treatment of choice is surgical resection. We reports a case of asymptomatic pheochromocytoma that was treated with tumor excision. To prevent intraoperative and postoperative complications, precise preoperative diagnosis and localization, as well as adequate preoperative management, are necessary.

A 30 year-old woman with a history of Behcet's disease was admitted to our clinic because of a paroxysmal attack of palpitations, headache, and ocular pain. Initially, we did not suspect a pheochromocytoma. We evaluated Behcet's disease activity because the cardiovascular and neurological symptoms mimicked those of Behcet's disease. Pheochromocytoma is often overlooked and can be fatal if not recognized and treated appropriately. In the present case, abdominal computerized tomography incidentally revealed a mass confirmed to be a pheochromocytoma in the left adrenal gland, and the tumor was successfully removed. This is the first Korean report of a pheochromocytoma in a patient with Behcet's disease. We suggest that pheochromocytoma should be included in the differential diagnosis of Behcet's disease if a patient presents with cardiovascular or neurological symptoms.

This is a case report of a pheochromocytoma which developed in a 62-year-old woman. The diagnosis of a pheochromocytoma originating from the right adrenal gland was incidentally established rentgenologically. Transthoracic adrenalectomy was undertaken, and e tumor weighing 33gm was obtained. A case of an elderly person with a nonfunctioning pheochromocytoma is with presented with review of the literature.

Between 1980 and 1991, we managed 12 cases of pheochromocytoma which consisted of 1 case of vesical pheochromocytoma, 1 case of malignant adrenal pheochromocytoma and 10 cases of benign adrenal pheochromocytoma including one case of bilateral pheochromocytoma. There were 6 men and 6 women and their mean are was 47 ranging from 17 to 67. Eleven patients complained of hypertension and headache. and one symptom free patient had nonfunctioning vesical pheochromocytoma. After diagnosis. various surgical management were proceeded in 11 patients. 1 patient who had bilateral tumor refused any operation`. Mean duration of follow-up after operation was 40.5 months (ranging from 8 to 127). Ten surgically mats were alive during follow up but one died of malignant adrenal pheochromocytoma 9 months after operation. One patient who received nonsurgical treatment had hypertension and headache despite of continued medical therapy.

Ectopic Cushing’s syndrome caused by pheochromocytoma is rare. We reported a 15-year-old female patient who was admitted to hospital with typical Cushing’s syndrome. She had not started menstruation. Her plasma adrenocorticotropic hormone (ACTH) and 24-hour urinary free cortisol levels were extremely high. Gonadal and progestational hormone levels were also abnormal. Abdominal computed tomography scans and enhanced scans revealed multiple irregular tumors in the right adrenal. Pelvic echogram showed an infantile uterus, while the ovaries were at an immature stage of development. Retroperitoneal laparoscopic right adrenalectomy was performed without intraoperative complications. Histology and immunohistochemistry of the tumor were consistent with pheochromocytoma. Retroperitoneal laparoscopic adrenalectomy is a safe procedure with satisfactory outcomes and allows for rapid recovery.

High-resolution imaging techniques have increased the detection rate of adrenal incidentaloma. We developed a method of liquid chromatography-tandem mass spectrometry (LC-MS/MS) for detection of plasma free metanephrine (MN) and normetanephrine (NMN) and evaluated its analytical performance and clinical efficacy in differential diagnosis of adrenal incidentaloma. After solid-phase extraction, chromatographic isolation of the analytes and internal standard was achieved by column elution in the LC-MS/MS system. The analytes were detected in multiple-reaction monitoring mode by using positive electrospray ionization: MN, transition m/z 180.1-->165.1; NMN, m/z 166.1-->134.1. This method was validated for linearity, precision, accuracy, lower limits of quantification and detection, extraction recovery, and the matrix effect. Plasma concentrations of MN and NMN of 14 patients with pheochromocytoma were compared with those of 17 healthy volunteers, 10 patients with essential hypertension, and 60 patients with adrenal adenoma. The assay's linear range was 0.04-50.0 and 0.08-100.0 nmol/L for MN and NMN, respectively. Assay imprecision was 1.86-7.50%. The accuracy ranged from -7.50% to 2.00%, and the mean recovery of MN and NMN was within the range 71.5-95.2%. Our LC-MS/MS method is rapid, accurate, and reliable and useful for differential diagnosis of adrenal incidentaloma.
