We describe a case of adrenal paragonimiasis with its computed tomographic and ultrasonographic findings. Computed tomogram showed a well enhancing oval mass at right adrenal gland and ultrasonogram showed a dumbbell-shaped hyperechoic mass saddling on the top of the right kidney. Surgical specimen was multicystic mass filled with creamy material.

OBJECTIVE: To describe a patient with adrenal insufficiency and bilateral adrenal enlargement and to review causes of adrenal insufficiency, with special emphasis on adrenal hemorrhage. METHODS: We present the clinical course of a woman with apparent septic shock, who responded poorly to treatment with inotropic agents. The possible cause and management of such cases are discussed. RESULTS: A 44-year-old woman with no prior major illness required medical attention because of severe hypotension, volume depletion, acute renal failure, and shock. Numerous laboratory and radiologic studies were performed to determine the cause of her shock state. She did not respond to several inotropic agents. When she was found to have adrenal insufficiency, initiation of treatment with glucocorticoids promptly alleviated her hypotension. CONCLUSION: Critically ill patients who have sudden unexplained hypotension that does not respond to supportive management should be screened for adrenal insufficiency. The current patient emphasizes the importance of considering this disorder in the differential diagnosis of hypotension that is unresponsive to pressor agents.

Two patients presented to hospital with clinical features of acute retroperitoneal haemorrhage. In each case, laparotomy revealed massive adrenal haemorrhage, and histological evidence of underlying neoplasia was eventually found.

In adrenal surgery, of note are increase of the incidence of incidentaloma because of a rapid advance of various image diagnostic procedures, change of the approach of choice due to the more accurate preoperative localization of the adrenal lesions, and the treatment of bilateral lesions. Additionally, the treatments of adrenocortical carcinoma and malignant pheochromocytoma and the method of cortisol withdrawal in Cushing's syndrome were reviewed and discussed. It is important for urologists to perform adrenal surgery appropriately by preoperatively elucidating the full picture of adrenal disorder.
A case of adrenal cyst with an immunohistochemical evidence of mesothelial origin is presented. A 73-year-old Japanese woman was referred to our hospital with a complaint of left flank pain. The diagnosis of left adrenal cyst was made based on the radiographic and hormonal examinations. The adrenal cyst was removed surgically. Histological examination revealed that the cyst was lined with either a single layer of squamous or cuboidal cells. In immunohistochemistry testing, the cells were positive for keratin and carbohydrate antigen 125, while they were negative for epithelial membrane antigen, vimentin, desmin, and factor VIII related antigen. Thus, the present case was classified as epithelial cyst of mesothelial origin.
PURPOSE: To determine the efficiency of gasless laparoscopic adrenalectomy, this procedure was compared to that with pneumoperitoneum. PATIENTS AND METHODS: Between February 1994 and December 1996, 17 gasless laparoscopic adrenalectomy were performed in 5 men and 12 women, 36 to 79 years old. Clinical diagnosis was primary aldosteronism in 8, pheocromocytoma in 2, incidentaloma in 4 and adrenal cyst in 3. When gasless laparoscopic adrenalectomy was performed, the laparoscope was inserted through the upper margin of the umbilicus by open laparotomy. To create a workable space, a 1.2 mm Kirschner wire was advanced subcutaneously below the costal arch and attached to a retractor. Operating time, estimated blood loss, changes of the end tidal CO2 concentration during operation, operative complications and postoperative course were compared to those with pneumoperitoneum in 12 cases. RESULTS: In both procedures, satisfying workable spaces were created in all cases. The mean operating time and estimated blood loss were 245 min and 201 ml without pneumoperitoneum, 317 min and 274 ml with pneumoperitoneum, respectively. The mean changes of end tidal CO2 concentration during operation were 3.2 mmHg without pneumoperitoneum and 5.1 mmHg with pneumoperitoneum. As operative complications, open operations were required in 2 cases (1 without pneumoperitoneum and another with pneumoperitoneum) to control intraoperative bleeding. They had the histories of transabdominal operations. Postoperative bleeding was observed in 2 cases (1 without pneumoperitoneum and another with pneumoperitoneum). One of them (with pneumoperitoneum) needed surgical management for hemostasis. Fever over 38 degrees C that occurred in 1 case with pneumoperitoneum appeared to be absorption fever. No differences were observed in the number of the days to the start of oral intake and for postoperative hospitalization between the two groups. CONCLUSIONS: Gasless laparoscopic adrenalectomy is available for most adrenal tumors. Suction could be used unrestrictedly and there were no hemodynamic or ventilatory effects due to pneumoperitoneum. This procedure appears to be safe and advantageous for the treatment of most adrenal tumors.
