Abstract
OBJECTIVE Pheochromocytomas are relatively rare neuroendocrine tumors of the adrenal medulla. Their variable clinical presentation and biologic behavior often make accurate diagnosis challenging. A variable spectrum of imaging appearances--some of which may also mimic other diseases--has been recognized. This article reviews the epidemiology; associations; and clinical, biochemical, pathologic, and multimodality imaging features of pheochromocytomas including diagnostic pearls and pitfalls. CONCLUSION Pheochromocytomas are often considered the great mimicker of other adrenal tumors. Because of their varied clinical, imaging, and pathologic appearances, accurate diagnosis can be challenging. The various imaging appearances on ultrasound, CT, MRI, and functional imaging can be complementary and have features that are useful for differentiating pheochromocytoma from other lesions of the adrenal.

Abstract
OBJECTIVE Adrenocortical carcinoma (ACC) is a rare, aggressive tumor arising from the adrenal cortex that typically presents late with a large mass. The increased use of cross-sectional imaging for unrelated reasons has led to a greater number of ACCs being detected incidentally at an earlier stage. Recognition of the typical clinical, biochemical, and imaging findings is imperative for rapid diagnosis, prompt intervention, and early use of the appropriate therapy. CONCLUSION Cross-sectional imaging with CT and MRI is essential for determining the extent of local and distant tumor spread. Complete surgical resection is currently the only potentially curative treatment of ACC, and the information attained from CT and MRI is important to guide surgery and further patient management.

Abstract
BACKGROUND Involvement of the inferior vena cava (IVC) is a controversial risk factor for surgical treatment of adrenocortical carcinoma (ACC). This study aims to assess the outcome of an aggressive surgical policy for ACC extending into the IVC and discuss treatment strategies based on a review of the literature. METHODS Over a 25-year period, 15 patients were treated for ACC extending into the IVC. The upper limit of the extension was the infrahepatic IVC in 2 patients, retrohepatic IVC in 6, and suprahepatic IVC in 7, including 4 with extension into the right atrium. Seven patients presented with concurrent metastases. The operative technique was thrombectomy (n = 13), partial resection with direct closure (n = 1), and total resection with replacement of the IVC (n = 1). Venous control was achieved by caval clamping alone (n = 4), hepatic vascular exclusion (n = 5), and the use of normothermic cardiopulmonary bypass or hypothermic circulatory arrest (n = 6). RESULTS Two patients died postoperatively. Ten patients died of metastatic complications at 4 to 31 months. Median survival time was 8 months. Three patients were still alive after 24, 25, and 45 months of follow-up, one of whom was reoperated at 17 months for a local recurrence. No evidence of recurrent intravenous involvement was found during follow-up in any patient in whom complete resection was achieved. CONCLUSIONS Our findings suggest that surgical treatment can be effective for management of ACC with extension into the IVC. Long-term prognosis is poor owing to delay in diagnosis, frequent associated metastatic disease and lack of effective adjuvant treatment.

Abstract
Technological developments in cross-sectional imaging have revolutionized the localization and characterization of functioning adrenal pathology. With effective use of modern imaging, the diagnosis of the cause and nature of functioning adrenal pathology can be reached speedily, accurately and efficiently in the majority of patients. We review the appearance of primary and secondary adrenal pathology, evaluate the diagnostic performance of imaging modalities, highlight newer technical developments, and propose a rational use of these tests in identifying functioning adrenal disease.

Abstract
A 53-year-old woman presented with Cushing's syndrome resulting from an adrenocortical adenoma, 6.5 cm in diameter and 75 g in weight, which is larger than usual. Endocrinological data of this patient showed adrenocorticotropin (ACTH)-independent hypercortisolemia. A computed tomography scan of the adrenal glands revealed a single large and well-encapsulated tumor with an irregularly shaped area of calcification and loss of parenchyma on the left adrenal. The right adrenal gland was atrophic. Laparoscopic removal of the left adrenal tumor was performed. The tumor was lobulated and clearly encapsulated, and the non-neoplastic area of the left adrenal was atrophic without any nodularity. The histological analysis confirmed the diagnosis of adrenal adenoma. In addition, this adenoma displayed histopathological features in common with ACTH-independent macronodular adrenocortical hyperplasia (AIMAH), including clear cell predominance, a pattern of small compact cell nests in clear cell areas, and very long cord-like arrangement of small compact cells. In AIMAH, adrenals are extremely enlarged and are more massive than in any other subtype of Cushing's syndrome. The fact that the present adrenocortical adenoma was larger than those typical adenomas of Cushing's syndrome may reflect an AIMAH-type cellular composition of clear cell predominance and small compact cell nests.

Abstract
BACKGROUND The purpose of the present paper was to carry out an audit of clinicopathological profile and treatment outcome in 13 children with functioning adrenal tumours. METHODS The medical records of 13 children with functioning adrenal tumours who were managed between June 1990 and January 1999 were reviewed. Demographic data, clinical features, biochemical and localization studies, operative details and follow-up records were studied. Children with neuroblastoma were excluded. RESULTS The mean age was 7.4 +/- 5.3 years. Seven patients had Cushing's syndrome (CS), two patients had virilizing tumours, three patients had phaeochromocytoma (PCC) and one patient had Conn's syndrome. All patients (except one child with CS) were treated surgically. Two children with adrenocortical carcinoma (ACCa) died during the perioperative period. Histopathological diagnosis was adrenal cortical adenoma (ACAd) in four patients, ACCa in five patients and PCC in three patients. Two ACCa patients died of metastases at 12 and 14 months, respectively, while the third is alive and well at 30 months. Children with ACAd are alive and well at 91, 56, 32 and 27 months postoperatively. Children with PCC are free of disease (normal urinary metanephrines) at 63, 18 and 8 months after surgery but require antihypertensive drugs in low doses. CONCLUSION The outcome of surgery is good in cases of ACAd and PCC. Although outcome is poor in ACCa, surgery remains the mainstay of treatment and offers good palliation.

Abstract
Most adrenal masses are detected on CT scans, but only a minority has morphologic features that are characteristic of a specific histologic diagnosis. In patients with clinical or biochemical features of a hyperfunctioning adrenal syndrome, CT detection of a unilateral adrenal mass typically leads to surgical resection, although functional assessment of the mass with iodomethylnorcholesterol or MIBG scintigraphy sometimes is used to augment the CT findings. In patients with a nonhyperfunctioning adrenal mass, chemical shift MR and CT densitometry have begun to replace percutaneous adrenal biopsy or serial follow-up CT as methods to establish a specific diagnosis. In this article the authors review the clinical features and imaging findings of patients with known or suspected adrenal masses.

Abstract
A case of adrenal cortical carcinoma with inferior vena cava (IVC) involvement is presented. Ultrasonography, computed tomography, and venacavography all presumptively showed a large mass over the upper pole of the left kidney with tumor thrombus in the IVC. However, aortography demonstrated that this mass was receiving its blood supply from the left inferior phrenic artery, aorta, and left renal artery. Radical surgery, including resection of the tumor and its adjacent organs (kidney, distal pancreas, spleen) and the tumor thrombus in the IVC, with the aid of cardiopulmonary bypass, was performed. We emphasize that adrenal cortical carcinoma can have tumor thrombi invading the IVC, and in such cases we suggest radical surgical removal of the tumor and the thrombus.

Abstract
The purpose of the study was to define the magnetic resonance (MR) imaging appearance of adrenocortical carcinoma (ACC) with current MR techniques. Eight patients with ACC underwent high-field-strength MR imaging with the following sequences: axial T1-weighted gradient echo, fat-suppressed T1-weighted spin echo, fat-suppressed T2-weighted spin echo, and gadolinium-enhanced T1-weighted gradient echo and fat-suppressed T1-weighted spin echo. Postcontrast images were also acquired in the sagittal (six patients) and coronal (three patients) planes. Out-of-phase gradient-echo images were obtained in two patients. Lesion morphology, signal intensity features, and presence of metastatic disease were retrospectively evaluated. MR imaging features of ACC included internal hemorrhage (seven of eight patients), central necrosis (seven of eight), and peripheral enhancing nodules (seven of eight). Out-of-phase images in two of two patients demonstrated signal loss compared with in-phase images, which may be a common feature of these tumors. Liver metastases were present in four patients. Consistent MR features of ACC are identified.

Abstract
We report on 2 cases of an adrenocortical carcinoma with vena caval involvement. Preoperative evaluation included a magnetic resonance imaging (MRI) scan confirming the presence of vena caval involvement. Extremely precise detail of the vena caval tumor thrombus was very helpful in preparing for the surgical extirpation. MRI detail far outweighed what was seen on the computed tomography scan and venacavogram. The MRI scan correlated exactly with what was found surgically. Although MRI scanning has been used to evaluate renal tumors with vena caval extension, few cases have been reported with similar adrenal tumors.

Abstract
BACKGROUND Adrenal cortical carcinoma is rare; the authors have treated only eight patients with the disease at Good Samaritan Regional Medical Center since 1974. No exhaustive collection of cases of this cancer has been done since 1952. METHODS The authors retrospectively reviewed the medical records of their eight patients with adrenal cortical carcinoma. They also searched the English literature from 1952 to 1992 for reports of patients with the disease. They treated each report as a series if two or more previously unreported patients were reported. They paid special attention to patients for whom stage of disease was noted at diagnosis, treatment with mitotane (o,p'-DDD) was used, and the outcome was reported. RESULTS Five were male and three were female patients. Five had nonfunctional tumors. None were pediatric. The authors found 1891 cases in the English literature. Adrenal cortical carcinomas are more common in women (58.6%) than in men (41.4%). The age distribution of tumors is bimodal, with peaks in the first and fifth decades. Tumors in children are more commonly functional (83.5% in female patients, 85.6% in male patients), although nonfunctional tumors are more common in older patients (84.7%). Most (68%) of these tumors are diagnosed late in disease when surgery is no longer curative. Only 35% of patients treated with mitotane had a clinical response. CONCLUSIONS Adrenal cortical carcinomas are diagnosed most often in children because of functionality and older men because of mass effect. Most tumors are discovered too late for curative resection. Treatment of metastatic disease with mitotane has limited success.

Abstract
Adrenal cortical carcinoma is a rare and highly malignant tumor. This retrospective study includes 99 patients (57 males and 42 females) reported to The Cancer Registry of Norway during the 15 year period from 1970 to 1984. The age adjusted incidence was 1.5 per million per year. Eighty-one patients were diagnosed with adrenal cortical carcinoma when still alive. In 18 cases the diagnosis was first made at autopsy. Median age at diagnosis was 54 years (range 2-88 years) with a slight male predominance. Information about initial symptoms was available in 67 patients, of whom 26 patients (18 females and 8 males) presented with clinically functioning tumors, the Cushing syndrome and virilization being most frequently encountered. Only 28 (35%) of 81 patients diagnosed when still alive had tumors confined to the adrenals. Half of the patients had distant metastases, with lungs and liver being the most frequent sites. Sixty-one patients underwent surgery; 51 patients had a radical or debulking operation and 10 patients had laparotomy with tumor biopsy. After a complete follow-up for at least 6 years (range 6-21 years), only 9 patients were still alive. Early stage (Stage I and II) and curative resection had a significant impact on the outcome of this disease. To improve prognosis, early diagnosis and radical surgery, if feasible, are needed.

Abstract
We report our experience with the management of 7 primary nonrenal parenchymal malignancies with vena caval tumor thrombus. Included are 3 cases of adrenal cortical carcinoma and 1 each of transitional cell carcinoma, embryonal cell testicular carcinoma, pheochromocytoma and primary small cell carcinoma of the lung with metastases to the kidney. Surgical treatment and followup are presented, as well as a review of the literature. An aggressive surgical approach is warranted because prolonged survivals free of disease are possible.
