BACKGROUND This study was designed to evaluate the clinical, endocrinological and histological characteristics of adrenal incidentalomas. METHODS Eighty patients (41, males; 38, females; age range 17-80 years) who were diagnosed with adrenal incidentaloma at Korea University Hospital from 1992 to 2003 were studied retrospectively. RESULTS Endocrinological investigation revealed 16 pheochrom...

Adrenal incidentalomas are commonly encountered in this era of ubiquitous imaging. The attenuation of the incidentaloma measured in Hounsfield units (HU) is an important step in the work up. Attenuation less than 10 HU indicates a benign lesion in more than 98% of cases, whereas attenuation greater than 30 HU is highly suspicious for adrenocortical cancer (ACC). Adrenal hematoma is rarely suspe...

One of the rarest situations regarding an adrenal incidentaloma is an adrenal cyst. We present the case of a 61-year-old male patient diagnosed with peritonitis. During surgery, a right adrenal tumor of 2 cm is discovered. The patient was referred to endocrinology. 6 months later the diameter of the tumor is 7 times bigger than the initial stage. It has no secretory phenotype, except for the sm...

A right adrenal tumor was found incidentally during abdominal computed tomography exam in a 51-year-old female patient, who had had diabetes and hypertension for more than 10 years. The computed tomography scan was arranged for possible pancreatic lesion by a neurologist. Norepinephrine level was high in the plasma and urine. Vanillylmandelic acid level was elevated in the urine. Diurnal cortis...

The adrenal ‘incidentaloma’ (AI) is an adrenal tumour greater than 1cm in diameter that is discovered incidentally during a radiologic examination performed for indications other than an evaluation of adrenal disease. 1,2,5,11,12 It is typically found on a CT scan done for other purposes and frequently causes much grief to the clinician who is unsure how to act upon the finding. Most AIs ar...

A case of 49-year-old woman with a retroperitoneal undifferentiated foregut cyst attached to the right adrenal gland is reported. The bronchogenic cyst is a type of foregut cyst with a cartilage component, but in this case the multicystic tumor lacked both cartilage and gland. It is quite rare among retroperitoneal tumors and has not been reported so far to have malignant potential. The preoper...

Composite pheochromocytoma (cPC) is extremely rare, arising in the adrenal medulla as a mixture of PC and other tumors of neural origin. We herein report on a case of adrenal incidentaloma post-operatively diagnosed as cPC with ganglioneuroblastoma (GNBL). The PC component had 7 points on the PASS, a Ki-67 index of 5.1%, a focal absence of sustentacular cells, and no genetic aberrations in succ...
