Abstract

Incidentaloma is defined as an asymptomatic mass lesion that shows no associated hormonal hyper- or hyposecretion. Adrenal incidentaloma is also a typical mass detection of which is known to have increased with improved imaging techniques such as CT or MRI. We report a case in which a pituitary incidentaloma is accompanied by an adrenal incidentaloma. The 65-year-old patient was admitted due to oropharyngeal pain, and had a medical history that included an operation for rectal cancer. The adrenal tumor had no function, but left adrenalectomy was performed for the evaluation of rectal cancer recurrence, which was diagnosed pathologically as a benign adrenocortical nodule. In our experience we have found that, in the case of multiple incidentalomas, it is important to evaluate the function or malignancy status of each.

Figure

• 

  Fig. 1 Sellar MRI findings. It is shown as pituitary incidentaloma, such as macroadenoma. Right side erosion of floor of sella with surrounding slightly low and high signal intensity lesion extending into left side parasella with suprasella and relatively contrast enhancement with right side deviation of infundibulum, about 1.2 cm in length are noted.

• 

  Fig. 2 Abdomen and pelvis CT findings. It is shown that nodular mass lesion on left adrenal area about 2.0 cm sized with homogenous and smooth margined wall which is like adrenal incidentaloma, but cannot be ruled out metastasis.

• 

  Fig. 3 Pathologic findings of adrenal mass. There are numerous benign cortical nodular lesions observed in normal adrenal cortical tissue. It is diagnosed as adrenal cortical nodule, favor of nodular hyperplasia (H&E stain, × 100).
