Abstract
Clinically significant endemic mycoses (fungal infections) in the United States (U.S.) include Blastomyces dermatitidis, Histoplasma capsulatum, and Coccidioides immitis/posadasii. While the majority of infections go clinically unnoticed, symptomatic disease can occur in immunocompromised or hospitalized patients, and occasionally in immune-competent individuals. Clinical manifestations vary widely and their diagnosis may require fungal culture, making the rapid diagnosis a challenge. Imaging can be helpful in making a clinical diagnosis prior to laboratory confirmation, as well as assist in characterizing disease extent and severity. In this review, we discuss the three major endemic fungal infections that occur in the U.S., including mycology, epidemiology, clinical presentations, and typical imaging features with an emphasis on the pediatric population.

Abstract
The differential diagnosis of retroperitoneal masses includes a variety of benign and malignant conditions, among which infections constitute a significant subgroup. Familiarity with these infectious pseudotumours could facilitate prompt diagnosis. In this report, we describe three patients with an infectious pseudotumour, which was clinically and radiologically highly suggestive of a neoplasm. The first patient was a 62-year-old woman with a history of Richter syndrome, who seven months after allogeneic haematopoetic stem cell transplantation from an unrelated donor presented with a renal mass. A renal biopsy at that time revealed necrotic tissue. The patient displayed multiple relapses of Richter syndrome (for which she received also chimeric antigen receptor T-cell therapy salvage chemotherapy) and remissions of the lymphoma as well as an Aspergillus pneumonia for which she was treated with intravenous ambisome and afterwards oral posaconazole. Since the renal mass persisted and to exclude malignancy, nephrectomy was performed which revealed the presence of fungal hyphae. The second patient was a 51-year-old man with a history of a low-grade non-muscle-invasive bladder urothelial carcinoma, who after Mycobacterium bovis Calmette-Guerin instillation presentedwith fever and a suspicious renal mass. A partial nephrectomy was performed. Intraoperative frozen section analysis and routine histology suggested a Mycobacterium bovis-associated lesion, which was confirmed by polymerase chain reaction (PCR) analysis. The third patient was an 85-year-old man who presented with loss of appetite, fatigue, and significant weight loss (24 Kg in less than a year) as well as a travel history. The laboratory tests showed a low sodium and a high potassium level. CT scans revealed a solitary lesion in the right lung, a small liver lesion as well as bilateral adrenal lesions. A CT-guided biopsy revealed the presence of Histoplasma capsulatum, which was confirmed by PCR analysis. A retrospective review of all parameters indicates that all three patients presented with some risk factors, such as immunosuppression, travel, or clinical history that could raise the suspicion of infection in order to be included in the differential diagnosis, thus providing an additional tool for timely diagnosis.

Abstract
Histoplasmosis is the fungal infection caused by Histoplasma capsulatum fungus. It is commonly found in a few endemic areas in the United States, where there is a large number of birds or bats and can spread through their droppings. Disseminated histoplasmosis is a severe manifestation of the fungal infection which is commonly seen in individuals with underlying immunosuppression. Our case is an unusual case of disseminated histoplasmosis in a 60-year-old, immunocompetent male patient with a history of significant alcohol abuse, which led to end stage liver failure. While the patient showed some signs of improvement initially upon beginning the treatment, he ultimately continued to deteriorate despite treatment due to an overwhelming histoplasmosis infection. This case demonstrates the importance of keeping a high index of suspicion even amongst immunocompetent patients with no obvious exposure to risk factors. It also shows that timely diagnosis with a high index of suspicion is required with an integrated treatment approach.

Abstract
Endocrine disorders associated with adrenal pathologies can be caused by insufficient adrenal gland function or excess hormone secretion. Excess hormone secretion may result from adrenal hyperplasia or hormone-secreting (ie, functioning) adrenal masses. Based on the hormone type, functioning adrenal masses can be classified as cortisol-producing tumors, aldosterone producing tumors, and androgen-producing tumors, which originate in the adrenal cortex, as well as catecholamine-producing pheochromocytomas, which originate in the medulla. Nonfunctioning lesions can cause adrenal gland enlargement without causing hormonal imbalance. Evaluation of adrenal-related endocrine disorders requires clinical and biochemical workup associated with imaging evaluation to reach a diagnosis and guide management.

Abstract
Non-traumatic adrenal crisis is a rare but critical diagnosis to make in emergency settings due to grave consequences. Various pathologies can present as acute crisis, such as spectrum of endocrine imbalance, ranging from catecholamine excess in pheochromocytomas to acute adrenal insufficiency related to glandular dysfunction. Critical manifestations may be due to structural causes related to adrenal hemorrhage, especially when they are bilateral. Oncological complications such as vascular invasion, tumoral bleed, rupture, and hormonal dysfunction can occur. Due to non-specific clinical presentation, these conditions may come as a surprise on imaging performed for other reasons. Recognition of these imaging findings is critical for appropriate patient management. Although there are few articles discussing non-traumatic emergencies in literature, this review is inclusive of all possible etiologies, thus provides a holistic approach and insight into each situation. Specific imaging approach is needed to tailor the diagnosis. This article will also discuss about the advanced imaging techniques that will complement diagnosis.

Abstract
OBJECTIVE Detailed studies of Addison's disease resulting from disseminated adrenal histoplasmosis (AH) are not available. We describe the presentation and prognosis of AH and cortisol status before and after antifungal therapy. DESIGN Single-centre retrospective hospital-based study of 40 consecutive adults with AH [39 males; age (mean ± SD) 53 ± 11 years] was conducted between 2006 and 2018. The median duration of follow-up was 2.5 years (range 0.2-12 years). PATIENTS AND METHODS AH was diagnosed by bilateral adrenal enlargement on CT scan and presence of Histoplasma by histology and/or culture of biopsied adrenal tissue. All patients received oral itraconazole and, if required, amphotericin B as per guidelines. ACTH-stimulated serum cortisol (normal > 500 nmol/L) was measured in 38 patients at diagnosis and re-tested after one year of antifungal therapy in 21 patients. RESULTS Seventy-three per cent of patients had primary adrenal insufficiency (PAI) and one-third had an adrenal crisis at presentation. HIV antibody was negative in all patients. Of the 29 patients who completed antifungal therapy, 25 (86%) were in remission at last follow-up. Overall, 8 (20%) patients died: three had a sudden death, four had severe histoplasmosis and one died due to adrenal crisis. No patient with PAI became eucortisolemic on re-testing after one year of antifungal therapy. Of the eight patients with normal cortisol at diagnosis, two developed adrenal insufficiency on follow-up. CONCLUSION All patients with AH tested negative for HIV antibody. While patients achieved a high rate of clinical remission after antifungal therapy, overall mortality was significant. Cortisol insufficiency did not normalize despite treatment.

Abstract
An 89-year-old woman presented with seizure and hyponatremia. CT and MRI demonstrated mass-like enlargement of the adrenal glands and multiple pulmonary nodules. PET/CT performed to evaluate for metastatic disease demonstrated intense F-FDG uptake within enlarged adrenal glands. Given mild uptake in the pulmonary nodules, the differential diagnosis for the adrenal uptake included lymphoma, granulomatous infection, and less likely, metastatic lung cancer.

Abstract
Invasive fungal and fungal-like infections contribute to substantial morbidity and mortality in immunocompromised individuals. The incidence of these infections is increasing-largely because of rising numbers of immunocompromised patients, including those with neutropenia, human immunodeficiency virus, chronic immunosuppression, indwelling prostheses, burns, and diabetes mellitus, and those taking broad-spectrum antibiotics. Invasive fungal pathogens include primary mycotic organisms such as Histoplasma capsulatum, Coccidioides immitis, Blastomyces dermatitidis, and Paracoccidioides brasiliensis, which are true pathogens and inherently virulent. Secondary mycotic organisms such as Candida and Aspergillus species, Cryptococcus neoformans, Pneumocystis jirovecii, and Mucorales fungi are opportunistic, less virulent pathogens. Nocardia and Actinomyces species are gram-positive bacteria that behave like fungi in terms of their growth pattern and cause fungal-like invasive indolent infections; thus, these organisms are included in this review. Fungal and fungal-like infections can affect a variety of organ systems and include conditions such as meningitis, sinusitis, osteomyelitis, and enteritis. As awareness of these infections increases, timely diagnosis and treatment will become even more important. Imaging has a critical role in the evaluation of disease activity, therapy response, and related complications. Using an organ-based approach with computed tomography, magnetic resonance imaging, and ultrasonography to gain familiarity with the appearances of these infections enables timely and accurate diagnoses. ©RSNA, 2017.

Abstract
Histoplasma capsulatum is a saprophytic fungus that in immunocompetent individuals causes self-limited pulmonary infection; however, in immunosuppressed patients involvement of the reticuloendothelial system, alimentary tract, urinary tract, and central nervous system is fairly common. Rarely patients present with bilateral adrenal masses which mimic tuberculosis and metastasis on radiology because of associated central necrosis. Ultrasound guided FNAC aided by special stains like Periodic Acid Schiff (PAS) and Gomori Methenamine Silver (GMS) may help in early diagnosis in such dubious cases. Polka dot macrophages were the clue to diagnosis of histoplasmosis on toluidine blue rapid staining, Hematoxylin & Eosin, and Pap stained smears. We report this case because of its rarity, diagnostic difficulty on radiology, and rapidity of diagnosis by FNA due of its characteristic cytomorphology.

Abstract
Purpose To determine if adrenal calcifications seen at computed tomography (CT) are associated with familial cerebral cavernous malformations (fCCMs) in carriers of the CCM1 Common Hispanic Mutation. Materials and Methods This study was approved by the institutional review board. The authors retrospectively reviewed abdominal CT scans in 38 patients with fCCM, 38 unaffected age- and sex-matched control subjects, and 13 patients with sporadic, nonfamilial cerebral cavernous malformation (CCM). The size, number, and laterality of calcifications and the morphologic characteristics of the adrenal gland were recorded. Brain lesion count was recorded from brain magnetic resonance (MR) imaging in patients with fCCM. The prevalence of adrenal calcifications in patients with fCCM was compared with that in unaffected control subjects and those with sporadic CCM by using the Fisher exact test. Additional analyses were performed to determine whether age and brain lesion count were associated with adrenal findings in patients with fCCM. Results Small focal calcifications (SFCs) (≤5 mm) were seen in one or both adrenal glands in 19 of the 38 patients with fCCM (50%), compared with 0 of the 38 unaffected control subjects (P < .001) and 0 of the 13 subjects with sporadic CCM (P = .001). Adrenal calcifications in patients with fCCM were more frequently left sided, with 17 of 19 patients having more SFCs in the left adrenal gland than the right adrenal gland and 50 of the 61 observed SFCs (82%) found in the left adrenal gland. No subjects had SFCs on the right side only. In patients with fCCM, the presence of SFCs showed a positive correlation with age (P < .001) and number of brain lesions (P < .001). Conclusion Adrenal calcifications identified on CT scans are common in patients with fCCM and may be a clinically silent manifestation of disease. © RSNA, 2017.

Abstract
PET/CT with (18)F-fluorodeoxyglucose (FDG) or using different radiocompounds has proven accuracy for detection of adrenal metastases in patients undergoing cancer staging. It can assist the diagnostic work-up in oncology patients by identifying distant metastases to the adrenal(s) and defining oligometastatic disease that may benefit from targeted intervention. In patients with incidentally discovered adrenal nodules, so-called adrenal "incidentaloma" FDG PET/CT is emerging as a useful test to distinguish benign from malignant etiology. Current published evidence suggests a role for FDG PET/CT in assessing the malignant potential of an adrenal lesion that has been 'indeterminately' categorized with unenhanced CT, adrenal protocol contrast-enhanced CT, or chemical-shift MRI. FDG PET/CT could be used to stratify patients with higher risk of malignancy for surgical intervention, while recommending surveillance for adrenal masses with low malignant potential. There are caveats for interpretation of the metabolic activity of an adrenal nodule on PET/CT that may lead to false-positive and false-negative interpretation. Adrenal lesions represent a wide spectrum of etiologies, and the typical appearances on PET/CT are still being described, therefore our goal was to summarize the current diagnostic strategies for evaluation of adrenal lesions and present metabolic and anatomic appearances of common and uncommon adrenal lesions. In spite of the emerging role of PET/CT to differentiate benign from malignant adrenal mass, especially in difficult cases, it should be emphasized that PET/CT is not needed for most patients and that many diagnostic problems can be resolved by CT and/or MR imaging.

Abstract
The discovery of an incidental adrenal mass (adrenal incidentaloma) continues to rise with the increasing use of cross-sectional imaging. Although most adrenal lesions are benign and asymptomatic, radiologists should guide evaluation of these lesions, whether benign or malignant. This article reviews the various imaging techniques used to evaluate adrenal masses and their relative strengths and weaknesses. It focuses on the most prevalent adrenal pathologies and their typical imaging characteristics, and concludes with a brief discussion of developing techniques, including diffusion-weighted imaging and dual-energy CT.

Abstract
Histoplasmosis is a fungal infection caused by Histoplasma capsulatum, which commonly presents as transient pulmonary infection that usually subsides without treatment. Disseminated histoplasmosis may affect almost all systems, including the reticuloendothelial system, lungs, gastrointestinal tract, renal tract, central nervous system, bone marrow, and adrenal glands. Adrenal gland is frequently involved in disseminated histoplasmosis but commonly present as unilateral mass; bilateral involvement is rare. It is also rare in immunocompetent hosts and only few cases have been reported in past. We report four cases of adrenal histoplasmosis with bilateral involvement. These cases were initially diagnosed cytopathologically on fine needle aspirations performed on adrenal glands. All these patients were immunocompetent and two of them also had associated adrenal insufficiency. Diagnosis of adrenal histoplasmosis can be easily made on fine needle aspiration cytology. Adrenal histoplasmosis can occur in immunocompetent individuals and should be considered in differential diagnosis of bilateral adrenal masses in immunocompetent individuals.

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
Although endemic mycoses are a frequent health problem in Latin American countries, clinical and epidemiological data remain scarce and fragmentary. These mycoses have a significant impact on public health, and early diagnosis and appropriate treatment remain important. The target population for endemic disease in Latin America is mostly represented by low-income rural workers with limited access to a public or private health system. Unfortunately, diagnostic tools are not widely available in medical centers in Latin America; consequently, by the time patients are diagnosed with fungal infection, many are already severely ill. Among immunocompromised patients, endemic mycoses usually behave as opportunistic infections causing disseminated rather than localized disease. This paper reviews the epidemiology of the most clinically significant endemic mycoses in Latin America: paracoccidioidomycosis, histoplasmosis, and coccidioidomycosis. The burdens of disease, typically affected populations, and clinical outcomes also are discussed.

Abstract
Histoplasmosis is a fungal disease endemic in central and eastern states of United States, South America, Africa, and Asia. It may present as chronic pulmonary infection or in disseminated form of infection. The disseminated form of histoplasmosis frequently affects the adrenal gland and is more likely to affect immunocompromised patients as compared to immunocompetent individuals. There are very few cases of adrenal histoplasmosis diagnosed on fine needle aspiration cytology. In the present era when fine needle aspiration has become popular modality for diagnosis, adrenal fine needle aspiration is still a less commonly practiced technique. We report eight cases of adrenal histoplasmosis diagnosed on fine needle aspiration cytology in patients with bilateral adrenal masses. The present case series supports the role of fine needle aspiration cytology of adrenal gland infections where surgery can be prevented and a definitive diagnosis can be made on which treatment can be offered.

Abstract
The adrenal gland is a common site of disease, with an abnormality prevalence as high as 9% in autopsy series. With the increasing use of CT, adrenal lesions are frequently found in the daily practice of radiology and are diagnosed in up to 5% of CT examinations performed for varied reasons. Imaging features on CT can establish a specific diagnosis of many of these lesions, including myelolipoma, hematoma and cysts. Once a diagnostic dilemma, now adenomas can be accurately diagnosed using unenhanced CT, chemical shift magnetic resonance imaging and CT contrast washout analysis. Because the adrenal gland is also a frequent site of metastasis, recent literature has focused on imaging characterization of adrenal masses for differentiation of adenomas from metastases. In patients without known malignancy, most adrenal lesions are benign and a specific diagnosis can now be made on the basis of imaging features. It is important to understand the prevalence of adrenal abnormalities because the gland is a common site of disorders, and the increased use of cross-sectional imaging has increased the frequency of detection of adrenal lesions. The prevalence of disease is important in predicting the risk of malignancy when an adrenal mass is discovered in a patient without known cancer. Detection of adrenal gland diseases has increased substantially with the advent and widespread use of imaging techniques. Although several imaging modalities can be used, CT has a central role in both detection and differential diagnosis of an adrenal lesion. The aim of this article is to review the CT findings of adrenal gland diseases.

Abstract
Infection with Histoplasma capsulatum occurs commonly in areas in the Midwestern United States and Central America, but symptomatic disease requiring medical care is manifest in very few patients. The extent of disease depends on the number of conidia inhaled and the function of the host's cellular immune system. Pulmonary infection is the primary manifestation of histoplasmosis, varying from mild pneumonitis to severe acute respiratory distress syndrome. In those with emphysema, a chronic progressive form of histoplasmosis can ensue. Dissemination of H. capsulatum within macrophages is common and becomes symptomatic primarily in patients with defects in cellular immunity. The spectrum of disseminated infection includes acute, severe, life-threatening sepsis and chronic, slowly progressive infection. Diagnostic accuracy has improved greatly with the use of an assay for Histoplasma antigen in the urine; serology remains useful for certain forms of histoplasmosis, and culture is the ultimate confirming diagnostic test. Classically, histoplasmosis has been treated with long courses of amphotericin B. Today, amphotericin B is rarely used except for severe infection and then only for a few weeks, followed by azole therapy. Itraconazole is the azole of choice following initial amphotericin B treatment and for primary treatment of mild to moderate histoplasmosis.

Abstract
The detection of incidental adrenal masses has increased substantially with the advent and widespread use of high-resolution cross-sectional imaging techniques such as CT and MRI. The work-up and treatment of these incidentally found adrenal masses continue to be a clinical challenge for radiologists, endocrinologists, and adrenal surgeons. The approach to the evaluation of most of these adrenal masses depends on the radiologic appearance of the lesion, and whether the patient has a known underlying malignancy. The aim of this article is to review imaging features of pathologic abnormalities of the adrenal gland. Recent advances in noninvasive imaging methods that attempt to differentiate benign from malignant lesions also are addressed.

Abstract
Differentiation of pathologic alterations of the adrenal glands is still a frequent and challenging problem of daily practice in radiology. Two main groups of patients have to be differentiated: those with clinical symptoms, mainly of endocrinopathies, and those in which a mass of the adrenal gland is detected incidentally. In the first group, magnetic resonance imaging (MRI) plays a minor role, although it allows to detect and often even differentiate the cause of the disease. In the second group, MRI has an excellent performance in differentiating between adenomas and non-adenomatous lesions of the adrenal glands.

Abstract
Adrenal histoplasmosis is one of the most common adrenal granulomatous infections in endemic areas. Although CT or MRI findings of adrenal histoplasmosis have been documented, there are no reports regarding 18F-fluorodeoxyglocose (FDG) positron emission tomography (PET) findings. We report a case of bilateral adrenal histoplasmosis showing a significantly high uptake of 18F-fluorodeoxyglocose on PET study. Adrenal histoplasmosis should be considered as one of the differential diagnoses in cases of adrenal tumors with intense FDG uptake, even in non-endemic areas.

Abstract
Gastrointestinal histoplasmosis (GIH) is an uncommon disease with protean manifestations. It may occur as a result of mediastinal histoplasmosis or in the setting of progressive dissemination. GIH may be misdiagnosed as inflammatory bowel disease, malignancy, or other intestinal diseases leading to inappropriate therapies and unnecessary surgical interventions. Patients with bowel obstruction, perforation, or bleeding, and systemic findings suggestive of histoplasmosis should be evaluated for GIH. This is especially true for immunosuppressed patients, especially those with AIDS. Diagnosis first requires consideration of histoplasmosis in the differential in patients with the above types of gastrointestinal abnormalities, and second, familiarity with a battery of mycologic and serologic tests. Progressive disseminated histoplasmosis (PDH) is lethal if left untreated, and treatment is highly effective. This review will focus on the clinical and histopathologic features of GIH, the approach to diagnosis, and recommendations for treatment.

Abstract
MR imaging is used commonly for imaging the adrenal glands. Its high-contrast resolution and multiplanar imaging capability enables the detection and characterization of many adrenal masses. The advent of chemical-shift imaging revolutionized the role of MR imaging in characterizing adrenal masses. In this article, the authors discuss the range of MR appearances of common and uncommon adrenal masses, focusing on the nonfunctioning incidentally discovered mass and its characterization methods. MR imaging is continuously improving. The increasing use of higher strength magnets and the introduction of newer coils, sequences, and techniques will help detect and characterize very small adrenal masses, quantify their fat content, and provide exquisite morphologic images of the gland and its vascular supply.

Abstract
The diagnosis of histoplasmosis depends on recognition of the different clinical manifestations of infection, accompanied by knowledge of the accuracy and limitations of tests used for diagnosis of fungal infections. Although most infections are asymptomatic, histoplasmosis can be severe, or even fatal, in patients who have experienced a heavy exposure, have underlying immune defects, or develop progressive disease that is not recognized and treated. This article provides an up-to-date clinical review of histoplasmosis, focusing on recognition, diagnosis, and management.

Abstract
Histoplasmosis remains a common infection in endemic regions of North America and Latin America, causing a broad spectrum of clinical findings. Experience during recurrent outbreaks in Indianapolis has shown the importance of immunosuppressive conditions including the acquired immunodeficiency syndrome (AIDS) as a risk factor for disseminated disease and expanded our knowledge of the common clinical manifestations. Pericarditis, rheumatologic manifestations, esophageal compression, and sarcoidlike manifestations were found to be relatively common findings in histoplasmosis. These studies have established the useful role of serologic testing and have led to the discovery of antigen testing for diagnosis of histoplasmosis. This experience also has offered the opportunity to examine the outcome of treatment in persons with AIDS, contributing to studies that have found itraconazole to be an excellent alternative to amphotericin B in persons with mild or moderately severe infection.

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
Adrenal histoplasmosis is a rare infection that can be misdiagnosed as tuberculosis. We present here a case of adrenal histoplasmosis in a 65 year-old male diabetic with marked weight loss. Laboratory investigations noticed an inflammatory syndrome and the abdominal computed tomography scanner reported an heterogenous left adrenal mass of 6 cm in diameter. Hormonal as well as bacteriological studies were negative. The patient was operated and the histopathological examination proved that the mass was a tuberculoma and an anti-tuberculous treatment was started. Four months later, the patient suffered from recurrence of symptoms and laboratory investigations confirmed the inflammatory syndrome and the abdominal computed tomography scanner showed a right adrenal mass. A surgical biopsy was performed and specific fungal researches proved that the lesion was due to Histoplasma capsulatum. The patient experienced a remarkable improvement under anti-fungal treatment.

Abstract
CT is the imaging procedure of choice for detecting adrenal masses. In patients with biochemical evidence of an adrenal endocrine syndrome, CT can detect or exclude an adrenal mass in a high percentage of cases. Radionuclide scintigraphy is a useful adjunct in selected cases to characterize an adrenal mass as functional cortical (NP-59) or medullary (MIBG) tissue. In this article, the spectrum of adrenal imaging findings in patients with Cushing's syndrome, Conn's syndrome (primary aldosteronism), and pheochromocytoma is described and illustrated. In patients without an adrenal endocrine syndrome, an adrenal mass is detected on CT as an incidental finding or during a search for metastatic disease. Although pathognomonic findings of adrenal hemorrhage or myelolipoma are occasionally demonstrated, most adrenal masses have nonspecific morphological CT features. Differentiation of common benign adenomas from nonadenomatous adrenal masses, including metastases, remains an important clinical problem. This article reviews the current status, advantages, and limitations of the following methods to characterize an adrenal mass: (1) percutaneous adrenal biopsy, (2) NP-59 scintigraphy, (3) unenhanced CT densitometry, and (4) opposed-phase chemical shift MRI.

Abstract
The purpose of this study was to determine the patterns of iodine-131 6 beta-iodomethylnorcholesterol (NP-59) imaging and the correlation with computed tomography (CT)-guided adrenal biopsy and follow-up in patients with bilateral adrenal masses. To this end we investigated a consecutive sample of 29 euadrenal patients with bilateral adrenal masses discovered on CT for reasons other than suspected adrenal disease. Adrenal scintigraphy was performed using 1 mCi of NP-59 injected intravenously, with gamma camera imaging 5-7 days later. In 13 of the 29 patients bilateral adrenal masses were the result of metastatic involvement from lung carcinoma (5), lymphoma (3), adrenocarcinoma of the colon (3), squamous cell carcinoma of the larynx (1), and anaplastic carcinoma of unknown primary (1). Among these cases the NP-59 scan demonstrated either bilaterally absent tracer accumulation (in eight, all with bilateral metastases proven by CT-guided biopsy or progression on follow-up CT) or marked asymmetry of adrenocortical NP-59 uptake (in five). Biopsy of the adrenal demonstrating the least NP-59 uptake documented malignant involvement of that gland in five of five patients. In two patients an adenoma was found simultaneously in one adrenal with a contralateral malignant adrenal mass. In each of these cases, the adenoma demonstrated the greatest NP-59 uptake. In 16 patients diagnosis of adenoma was made on the basis of (a) CT-guided adrenal biopsy of the gland with the greatest NP-59 uptake of the pair (n = 4), or (b) adrenalectomy (n = 2), or (c) absence of change in the size of the adrenal mass on follow-up CT scanning performed 6 months to 3 years later (n = 10).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Tubercular adrenalitis presents with adrenal enlargement prior to its atrophy and calcification. Imaging modalities like ultrasound, computerized tomography (CT), and magnetic resonance imaging have depicted adrenal enlargement due to various causes. Presented is a clinical-cum-CT review of 14 cases of tubercular adrenal enlargement with addition of five new cases and their CT follow-up.

Abstract
We describe three patients with puzzling systemic illnesses in whom computed tomography (CT) led to the diagnosis of active adrenal histoplasmosis. CT was performed in two patients because of gastrointestinal symptoms and weight loss and in the third because of fever developing 2 years after an apparent cure of histoplasmosis. All three patients had adrenal enlargement on CT with features of granulomatous adrenal disease in two. Hormone assays performed after CT supported the diagnosis of adrenal insufficiency and fine-needle adrenal aspiration biopsy with special stains of the aspirates showed histoplasma organisms in all three patients. The combination of adrenal enlargement on CT and laboratory findings of adrenal insufficiency should suggest the diagnosis of histoplasmosis, especially in endemic areas.
