AimsTo review the morphology of the adrenal glands in multiple endocrine neoplasia type 1 (MEN1) on computed tomography (CT) to compare the results with established normal values for adrenal size and nodularity and to correlate adrenal size with serum cortisol secretory dynamics.Materials and methodsTwo observers independently reviewed the adrenal CT in 28 patients with MEN1, measuring the maximum width of the body of the gland and the medial and lateral limbs. Incidence and location of nodules >5 mm within the gland were recorded. Following exclusion of known cases of Cushing's syndrome, adrenal gland size was compared with previously documented normative data. Adrenal gland size was compared between patients with normal and abnormal cortisol dynamics.ResultsComparison of mean adrenal size in MEN1 patients with normative data showed that the adrenal limbs were significantly larger in MEN1 than normal (P<0.0001 in all four limbs). Adrenal body was also significantly larger (P<0.05). Nodules were demonstrated in 17 (60%) of patients (versus 0.4–2% in the normal population). No statistically significant correlation was demonstrated between adrenal limb hyperplasia and abnormal cortisol dynamics.ConclusionsIn patients with MEN1, adrenal limb hyperplasia and adrenal nodules are significantly more common than in the normal population, a phenomenon not previously documented in a quantitative manner. There was no significant correlation between adrenal limb hyperplasia and abnormal cortisol dynamics.

With the steep increase in the use of cross-sectional imaging in recent years, the incidentally detected adrenal lesion, or "incidentaloma", has become an increasingly common diagnostic problem for the radiologist, and a need for an approach to classifying these lesions as benign, malignant or indeterminate with imaging has spurred an explosion of research. While most incidentalomas represent benign disease, typically an adenoma, the possibility of malignant involvement of the adrenal gland necessitates a reliance on imaging to inform management decisions. In this article, we review the literature on adrenal gland imaging, with particular emphasis on computed tomography, magnetic resonance imaging, and photon-emission tomography, and discuss how these findings relate to clinical practice. Emerging technologies, such as contrast-enhanced ultrasonography, dual-energy computed tomography, and magnetic resonance spectroscopic imaging will also be briefly addressed.

Renal cell cancer metastases without evidence of a primary tumor are extremely rare. These variants are usually showed as a spontaneous description of single clinical cases. Aim.This contribution is a clinical follow-up of synchronous renal cell cancer metastases of unknown primary site. Results.A 52-year-old patient U. with a history of increased blood pressure, up to 170/100 mmHg for the last 5 years, who had undergone many instrumental examinations, including ultrasound examination, because of this disease. The computed tomography of the abdomen showed a 4975 mm heterogeneous tumor in the right adrenal gland in October 2017. The combined positron emission and X-ray computed tomography showed a 795441 mm mass in the right adrenal gland, associated with elevated fluorodeoxyglucose metabolic activity SUVmax 7.25. Focal accumulation of the radiopharmaceutical SUVmax 4.31 in a 171124 mm mass was detected in the space of bifurcation in the mediastinum. The lytic lesion (1015 mm) was found in right superior L3 articular process. The patient underwent retroperitoneoscopic adrenalectomy and thoracoscopic removal of mediastinal tumor in November 2017 because of the oligometastatic nature of the process. The histological study identified clear-cell carcinoma with areas of papillary structure in the right adrenal gland. The immunohistochemical study showed carcinoma cells intensively expressing CD10, and some other cells RCC. The immune phenotype of the tumor was identified as clear-cell renal cell carcinoma. The immunohistological and immunohistochemical analysis reviled the metastases of the same variant of renal cell carcinoma in one of 9 lymph nodes. The patient was treated with pazopanib. The primary renal tumor was not detected during the dynamic observation, including the application of annual combined positron emission and X-ray computed tomography. The patient is alive without disease progression with a follow-up of 32 months. Conclusion.Metastases of clear-cell renal cell carcinoma, including adrenal gland, without evidence of a primary site are extremely rare. The main method of treatment is a combination of surgery and targeted therapy, providing long-term local control of the course of the disease.

The adrenal incidentaloma is a lesion of a different etiology and found incidentally in patients who underwent a diagnostic study not about the disease of this organ. Lesions can be both hormonally inactive and hormonally active, can arise from different zones of the adrenal gland or have non-specific organ affiliation, can be benign or malignant. Computed tomography characterization of these lesions, especially the differential diagnosis of benign and malignant, is extremely important for the correct diagnosis in order to provide adequate management of the patient. The article presents the key computed tomography criteria that allow radiologist to characterize the lesion most accurately and consider appropriate diagnosis.

Synacthen Test

A 64-year-old man presented to the emergency department with generalised fatigue and dizzy spells. His background history includes a previous admission with right leg deep vein thrombosis, provoked by pneumonia. Laboratory results showed evidence of hyponatremia and hyperkalaemia. A synacthen test was performed that indicated hypoadrenalism. CT of his abdomen revealed enlarged adrenal glands bilaterally. Adrenal antibodies and positron emission tomography (PET) scan were performed to assess the cause of enlarged adrenals. PET scan showed no evidence of increased uptake. Adrenal antibodies were found to be negative. Tuberculous (TB) adrenalitis was the principle differential diagnosis. TB QuantiFERON was strongly positive. Following 9 months of TB treatment, surveillance CT scan indicated a significant reduction in adrenal gland size. However, subsequent events culminated in a retrospective review of CT scans questioning the initial clinical diagnosis and suggesting that the observed adrenal gland enlargement was secondary to bilateral adrenal infarction and haemorrhage. Equally, the subsequently observed marked reduction in adrenal gland size was not secondary to an assumed response to TB therapy, but rather the sequela of infracted atrophied adrenal glands, as a manifestation of the underlying antiphospholipid syndrome (APS). The case highlights the importance of recognising adrenal insufficiency in patients with a history of APS. It also illustrates the role of multidisciplinary meetings in the management of such complex cases.

A 23-year-old woman was referred to our center with hirsutism, acne, weight gain, weakness, and irregular menses. Laboratory tests revealed increased levels of cortisol and sex hormones, and reduced adrenocorticotropic hormone levels. The patient underwent a right adrenalectomy. Pathology of the resected right adrenal gland showed an adrenal carcinoma. Computed tomography 8 months after the surgery revealed a thymic mass that was not detected preoperatively. The frequency of rebound thymic hyperplasia after normalization of hypercortisolism is not known, but possibly as high as 40%. Physicians must be aware of this phenomenon to avoid unnecessary thoracic surgery.

Adrenal sarcomatoid carcinomas are extremely rare tumors presenting with extensive locoregional spread at the time of diagnosis. Patients succumb to metastases within a couple of months. As a result, very few cases are reported in the literature until now. We present a case of a 62-year old female with non-functional sarcomatoid carcinoma of the right adrenal gland. There was no radiological evidence of locoregional metastases. Patient underwent right adrenalectomy. Follow up after 3 months showed para-aortic lymphadenopathy and similar left adrenal mass on computed tomography. Patient refused further treatment and succumbed to the disease. A brief case report with review of literature is presented.
