Acute spontaneous non-hemorrhagic adrenal infarction with systemic lupus erythematosus and antiphospholipid antibody syndrome: A case report.

RATIONALE: Adrenal infarction (AI) is a rare type of adrenal damage, which is relatively common in systemic lupus erythematosus, antiphospholipid antibody syndrome (APS) and pregnancy. The diagnosis of AI is mainly by computed tomography (CT) and magnetic resonance imaging, but is easily confused with other adrenal disease. Hence, this report details a condition of AI with systemic lupus erythematosus, APS and made a differential diagnosis from imaging. PATIENT CONCERNS: We report a case of a 55-year-old woman with pain in her fossa axillaries and inguinal regions. Then CT scan disclosed bilateral adrenal diseases, and the patient was diagnosed with systemic lupus erythematosus, APS and AI after additional autoimmune examinations. DIAGNOSES: The patient was diagnosed as systemic lupus erythematosus with lupus nephritis, hematological damage and oromeningitis, APS, AI and secondary blood coagulation disorders. INTERVENTIONS: The patient was treated with methylprednisolone, hydroxychloroquine and low molecular heparin. OUTCOMES: The patient relieves and remains well 1 year after treatment. LESSONS SUBSECTIONS: AI can be divided hemorrhagic and non-hemorrhagic, with bilateral lesions more common. In our case, the AI was bilateral, partially involved and non-hemorrhagic, and the "cutoff sign" was first put forward in CT, which might assist the diagnosis.

Characteristics of Adrenal Hemorrhage: A Single Clinic's Experience.

<b>Introduction:</b> Adrenal hemorrhage (AH) is a very rare and potentially life-threatening disease which may be secondary to trauma or of non-traumatic etiology.<b>Aim:</b> The aim of the study was to present the characteristics and management of adrenal hemorrhage and show that adrenal hemorrhage is more common than expected and that the clinical symptoms are not specific.<b>Materials and methods:</b> This retrospective study involved 199 patients with postoperative diagnosis of adrenal hemorrhage.<b>Discussion:</b> The factors identified as potential causes of adrenal hemorrhage are adrenocortical carcinoma, pheochromocytoma, and adrenal adenoma. The study group included 199 patients with postoperative diagnosis of AH. It showed that all patients with postoperative diagnosis had pheochromocytoma (n = 54), adrenal adenoma (n = 68), or adenocarcinoma (n = 17). If we look more careful at the results, we can find only 30% of patients (n = 39) with preoperative diagnosis of AH. This group of 39 patients was prepared for expedited surgery. In this group of patients, the preoperative diagnosis of AH was pheochromocytoma 28% (n = 11), adenocarcinoma (n = 4), and adrenal adenoma (n = 9).<b>Conclusions:</b> Bleeding into adrenal tumors is still an insufficiently understood topic due to its unpredictability and, as can be seen in our material, of varying severity. Out of 199 patients, only 30% (n = 39) were prepared for surgery with a preoperative diagnosis of AH; most of them had pheochromocytoma. We suggest that is very important to prepare patients for surgery with a preoperative diagnosis of AH using α-adrenoreceptor antagonists. Prolongation of the diagnostic process (time between the imaging examination and the surgery) may result in the disease progressing and adrenal bleeding.

[Pseudocyst of adrenal gland. Case report]. / Pseudoquiste de glándula suprarrenal. Reporte de un caso.

Background: Adrenal gland cysts are a rare entity, with a reported incidence in post-mortem series of 0.06-0.18%. However, the incidence seems to be increasing in recent years. The presentation of adrenal gland cysts is usually asymptomatic, but those cases in which symptoms are present are usually non-specific, which makes adrenal cysts generally recognized as incidentalomas. The finding is mainly made by computed tomography. The main objective of this article was to describe the clinical course of a patient with an adrenal gland pseudocyst, which is accompanied by symptoms of compression and persistent pain of long evolution in the left flank. Clinical case: A 65-year-old female patient attended the emergency room of a second-level hospital due to an increase in volume of the abdominal region with a sensation of fullness, heartburn, vomiting and pain. Computed tomography was performed, which reported a cystic mass and, later, exploratory laparotomy plus adrenalectomy were carried out. The pathology analysis reported a diagnosis of a 10 x 15 x 14 cm solid, cystic, and adherent tumor, coinciding with a pseudocyst of the adrenal gland. Conclusions: Adrenal gland cysts are rare. Computed tomography is recommended for its diagnosis and the standard of treatment is surgical intervention in the presence of symptoms.

Introducción: los quistes de glándula suprarrenal son una entidad rara, con un reporte en la incidencia de series post mortem de 0.06-0.18%. Sin embargo, la incidencia parece ir en aumento en los últimos años. La presentación de los quistes de glándula suprarrenal es habitualmente asintomática, pero en aquellos casos en que se presentan síntomas, estos suelen ser inespecíficos, lo cual hace que los quistes suprarrenales generalmente sean reconocidos como incidentalomas. El hallazgo se hace principalmente mediante tomografía computarizada. El objetivo principal de este artículo fue describir el curso clínico de una paciente con un pseudoquiste de glándula suprarrenal, que se acompaña de síntomas de compresión y dolor persistente de larga evolución en el flanco izquierdo. Caso clínico: mujer de 65 años que acudió a urgencias de un hospital de segundo nivel por aumento de volumen de región abdominal con sensación de plenitud, pirosis, vómito y dolor. Se realizó tomografía computarizada que reportó masa quística; posteriormente se realizó laparotomía exploradora y adrenalectomía. El análisis de patología reportó diagnóstico de tumor de 10 x 15 x 14 cm, sólido, quístico y adherido, coincidente con pseudoquiste de glándula suprarrenal. Conclusiones: los quistes de glándula suprarrenal son raros. Para su diagnóstico se recomienda realizar tomografía computarizada y el estándar de tratamiento es la intervención quirúrgica ante la presencia de sintomatología.

Association between gut microbiota and adrenal disease: a two-sample Mendelian randomized study.

Background: Some observational studies and clinical experiments suggest a close association between gut microbiota and metabolic diseases. However, the causal effects of gut microbiota on adrenal diseases, including Adrenocortical insufficiency, Cushing syndrome, and Hyperaldosteronism, remain unclear. Methods: This study conducted a two-sample Mendelian randomization analysis using summary statistics data of gut microbiota from a large-scale genome-wide association study conducted by the MiBioGen Consortium. Summary statistics data for the three adrenal diseases were obtained from the FinnGen study. The study employed Inverse variance weighting, MR-Egger, and MR-PRESSO methods to assess the causal relationship between gut microbiota and these three adrenal diseases. Additionally, a reverse Mendelian randomization analysis was performed for bacteria found to have a causal relationship with these three adrenal diseases in the forward Mendelian randomization analysis. Cochran's Q statistic was used to test for heterogeneity of instrumental variables. Results: The IVW test results demonstrate that class Deltaproteobacteria, Family Desulfovibrionaceae, and Order Desulfovibrionales exhibit protective effects against adrenocortical insufficiency. Conversely, Family Porphyromonadaceae, Genus Lachnoclostridium, and Order MollicutesRF9 are associated with an increased risk of adrenocortical insufficiency. Additionally, Family Acidaminococcaceae confers a certain level of protection against Cushing syndrome. In contrast, Class Methanobacteria, Family Lactobacillaceae, Family Methanobacteriaceae, Genus. Lactobacillus and Order Methanobacteriales are protective against Hyperaldosteronism. Conversely, Genus Parasutterella, Genus Peptococcus, and Genus Veillonella are identified as risk factors for Hyperaldosteronism. Conclusions: This two-sample Mendelian randomization analysis revealed a causal relationship between microbial taxa such as Deltaproteobacteria and Desulfovibrionaceae and Adrenocortical insufficiency, Cushing syndrome, and Hyperaldosteronism. These findings offer new avenues for comprehending the development of adrenal diseases mediated by gut microbiota.

Adrenal Pathologies.

Adrenal pathologies have variable clinical presentations and primary care providers should be aware of common and serious adrenal disorders. All adrenal masses require evaluation for malignancy, whether primary or metastatic, and all masses require evaluation for inappropriate hormonal secretion. In the event of adrenal insufficiency, the etiology of cortisol inadequacy must be identified and appropriately treated to prevent life-threatening complications.

Endocrine Emergencies.

Endocrine emergencies encompass a group of conditions that occur when hormonal deficiency or excess results in acute presentation. If these endocrine disorders are not rapidly identified or if specific treatment is delayed, significant complications or even death may occur. This article outlines the basics of endocrine emergencies involving the thyroid, parathyroid, pituitary, pancreas, and adrenal glands. It discusses various causative factors, diagnostic approaches, and treatment modalities, emphasizing the significance of preventive measures. This article is aimed at guiding health care professionals, and this overview seeks to enhance understanding and improve patient outcomes in managing endocrine emergencies.

Reducing the Gap in Knowledge and Expectations between Clinicians and People with Polycystic Ovary Syndrome or Adrenal Conditions: Simulation via Instant Messaging-Birmingham Advance: Patient and Public Involvement (SIMBA-PPI) Study.

BACKGROUND: To evaluate the efficacy of SIMBA as an educational intervention for both HCPs and people with either PCOS or adrenal conditions and to study the change in knowledge of people with PCOS or adrenal conditions about the conditions and expectations from the HCPs involved in their care following SIMBA-PPI sessions. METHODS: Two SIMBA-PPI sessions (SIMBA-PPI Polycystic ovary syndrome (SIMBA-PCOS) and SIMBA-PPI Adrenal conditions (SIMBA-Adrenal conditions)) were conducted in September 2021 and March 2022. In both sessions, HCPs interacted with moderators on patient management through WhatsApp. Patients with respective conditions underwent workshop-style learning in the same cases. SIMBA-PCOS transcripts were also translated into Brazilian Portuguese and workshops were held in both Brazilian Portuguese and English. The two groups (HCPs and patients) were then brought together to discuss exploring gaps in knowledge and expectations. The Wilcoxon Signed-Rank test compared differences in pre- and post-SIMBA self-reported confidence levels in HCPs and patients. Qualitative data from the online recordings were transcribed and analysed with inductive thematic analysis to identify gaps in knowledge and expectations from managing the cases. RESULTS: 48 HCPs and 25 patients participated in our study. When compared to pre-SIMBA confidence levels, SIMBA-PPI sessions effectively improved clinicians' confidence in managing PCOS (40.5%, p < .001) and adrenal conditions (23.0%, p < .001) post-SIMBA. Patient participants' confidence in HCPs significantly increased in the PCOS session (SIMBA-PCOS: 6.25%, p = 0.01). CONCLUSIONS: Integration of PPI into SIMBA improved HCPs' confidence in managing PCOS and adrenal conditions. SIMBA-PPI also improved patients' confidence in HCPs. Our findings suggest that participating in SIMBA-PPI sessions can reduce the gap in knowledge and expectations between patients and HCPs involved in their care.

Adrenal cysts less than 10 cm can be safely observed.

BACKGROUND: Adrenal cysts are rare and appropriate management is unclear due to a lack of data on their natural history. Understanding adrenal cyst growth patterns would assist in clinical management. METHODS: This single-institution study included all adult patients diagnosed with simple adrenal cysts between 2004 and 2021. Baseline characteristics and outcomes of those who underwent resection (ADX) or observation (OBS) were compared using the chi-squared test, student's t-test, and Wilcoxon rank-sum test. Growth curves and sensitivity analysis were plotted for all patients who had follow-up imaging. RESULTS: We identified 77 patients with imaging-confirmed adrenal cysts. The majority were female (75.3%) and more than half were white (55.8%). One-third of patients underwent ADX, and the remaining were observed. ADX patients were younger (median age [IQR]: 55.5 y [45.0-68.2 y] vs. 44.2 y [38.7-55.0 y], p = 0.01) and more likely to be Hispanic (12% vs. 0%, p = 0.05). ADX patients presented with larger cysts (5.6 vs. 2.6 cm, p = 0.002). The median time from diagnosis to last follow-up was 1.1 y for ADX and 4.1 y for OBS. Average growth for OBS was 0.3 cm/y, while average growth for ADX was 3.9 cm/y. In ADX patients, cysts >10 cm grew significantly faster than cysts <10 cm (median growth rate 13.2 cm/y vs. 0.3 cm/y, p < 0.05). There was no adrenal malignancy diagnosis, hyperfunctionality, or observation-related complications (e.g., rupture). CONCLUSION: While size >4-6 cm has guided surgical referral for solid adrenal masses, this study demonstrates a size threshold of 10 cm, below which asymptomatic, simple adrenal cysts can safely be observed.

Neonatal adrenal haemorrhage with contralateral scrotal haematoma and inguinal ecchymosis.

Neonatal adrenal haemorrhage (NAH) is more frequently described in neonates due to their relatively larger size and increased vascularity. While most are asymptomatic, they can present with anaemia, jaundice, abdominal mass, scrotal haematoma or more severe complications such as shock and adrenal insufficiency. Scrotal haematoma seen with NAH may be mistaken for other more serious conditions causing acute scrotum. Prompt sonographic examination that includes the bilateral adrenal glands may help to detect NAH early and to avoid unnecessary interventions. Cases of NAH causing ipsilateral inguinal ecchymosis and scrotal haematoma have been reported, but contralateral haematomas are very rare. In this report, we present a unique case of a neonate with an antenatally acquired adrenal haematoma complicated with an acute peripartum rebleeding manifesting as a contralateral scrotal haematoma and inguinal ecchymosis. The NAH was treated conservatively and resolved on follow-up imaging.

Challenges in genetic screening for inherited endocrinopathy affecting the thyroid, parathyroid and adrenal glands in Singapore.

Significant progress has been made in the understand-ing of many human diseases, especially cancers, which has contributed to improved and increased survival. The Human Genome Project and The Cancer Genome Atlas project brought about a new era, with an understanding of inherited diseases at a molecular level, which subsequently facilitated the option of precision medicine. Precision medicine has helped tailor treatment decisions at an individual level, for instance in terms of surgical treatments or targeted therapies in advanced diseases. Despite the increasing advances in genetic-lead precision medicine, this has not translated into increasing uptake among patients. Reasons for this may be potential knowledge gaps among clinicians; on reasons for poor uptake of genetic testing such as for cultural, religious or personal beliefs; and on financial implications such as lack of support from insurance companies. In this review, we look at the current scenario of genetic screening for common inherited endocrine conditions affecting the thyroid, parathyroid and adrenal glands in Singapore, and the implications associated with it.

Clinical characteristics of systemic lupus erythematosus patients with adrenal hemorrhage.

INTRODUCTION: Adrenal hemorrhage (AH) is a rare condition and severe cases can lead to acute adrenal insufficiency with potentially life-threatening consequences. AH can be caused by a variety of etiologic factors, including systemic lupus erythematosus and antiphospholipid syndrome (APS). The early identification and treatment of these patients improves their prognosis. OBJECTIVE: The aims of this study were to analyze and summarize the clinical characteristics of systemic lupus erythematosus patients with AH. METHODS: The clinical characteristics of 6 systemic lupus erythematosus patients complicated with AH admitted to Peking Union Medical College Hospital and Beijing Shijitan Hospital from May 2004 to April 2022 were retrospectively analyzed. RESULTS: The diagnosis of AH was based on computed tomography (CT) findings. Two patients had bilateral lesions, and the other 4 patients had unilateral lesions. The symptoms of adrenal insufficiency were observed in 2 patients. The frequent presenting symptoms were abdominal pain, lower abdominal distension, vomiting, weakness, fever, arthrodynia, and skin rash. Four patients had APS. Five patients (4 patients with APS and 1 patient without APS) had thromboembolic events. All patients received glucocorticoid and immunosuppressant therapy. Five patients were treated with anticoagulant therapy. Follow-up imaging examinations showed a partial or total regression of the lesions after treatment. CONCLUSIONS: In the proper clinical setting, having high clinical suspicion for AH, early diagnosis and timely management is crucial to avoid life-threatening adrenal insufficiency. Key Points • AH is a rare condition and severe cases may lead to death. It can be caused by a variety of etiologic factors, including SLE. • In patients with SLE, especially combined with APS, if they complain of abdominal pain, particularly when common gastrointestinal involvement is difficult to explain, a high index of clinical suspicion is needed for the diagnosis of AH. • Early identification of AH in SLE patients can improve their prognosis.

Retrospective application of a validated algorithm for estimation of adrenal gland volume after computed tomography on 46 dogs undergoing adrenalectomy.

Canine adrenal gland volume can be predicted based on body weight and computed tomography (CT) measurements using a validated algorithm. Use of this algorithm to detect adrenal pathology, including hyperplasia, hypoplasia and neoplasia, in clinical cases has not been described. The objective of this study was to illustrate application of the algorithm by estimating subject-specific adrenal gland volume in a historical cohort of dogs with known adrenal disease. Forty-six dogs that underwent CT and subsequent adrenalectomy were included. Clinical records and CT images from dogs that underwent adrenalectomy and histologic examination of the excised adrenal gland(s) were reviewed. Normal adrenal gland volumes for each dog were estimated using the algorithm, and compared with measured volumes of the affected glands. Linear measurement of the largest lesion diameter was also recorded. Fifty-eight adrenal glands were removed from 46 dogs, with pathology confirmed in all glands. Pathology included 28 adenomas, 13 carcinomas, 11 pheochromocytomas and 6 other benign pathologies. The volume of all removed adrenal glands was measured to be larger than the expected normal volume estimated by the algorithm, ranging from 1.1 to 212.9 times larger than estimated. Adrenal glands with malignant and benign pathology showed variable volumes with overlapping ranges recorded. Assessment of the dimensions of any focal lesion against a cut-off of 20 mm failed to discriminate malignancy. This study illustrates and supports the application of a validated volumetric algorithm for estimation of subject-specific adrenal gland volume to identify the presence of pathology and as a tool to assist clinical decision-making.

Clinical characteristics and outcomes of adrenal hemorrhage.

BACKGROUND: Although uncommon, adrenal hemorrhage has multiple etiologies. Because clinical characteristics, management, and outcomes of patients with adrenal hemorrhage are inadequately described, we examined the underlying etiology, need for intervention, evolution of imaging characteristics, and adequacy of subsequent evaluation. METHODS: We performed a retrospective review of patients diagnosed with adrenal hemorrhage (radiologist-confirmed density consistent with hemorrhage on computed tomography) from 2005 to 2021 at a university-based institution. Demographic characteristics, hemorrhage etiology, and subsequent follow-up were analyzed. RESULTS: Of 193 adrenal hemorrhage patients, the mean age was 49.2 ± 18.3 years, and 35% were female. Clinical presentations included trauma (47%), abdominal or flank pain (28%), incidental findings on imaging acquired for other reasons (12%), postoperative complication (8%), or shock (3%). Hemorrhage outside of the gland was present in 62% of patients. Unilateral hemorrhage was more frequent (93%) than bilateral (7%). A total of 12% of patients had nodules, but only 70% of these were identified on initial imaging, and only 43% had hormonal evaluation. Of 7 patients who had adrenalectomy or biopsy, pathology was either benign (57%) or nonadrenal malignancy (43%). No adrenocortical carcinomas were identified. Follow-up imaging was performed in 56% of patients and revealed decreased, stable, resolved, or increased adrenal hemorrhage size in 39%, 19%, 30%, and 12% of patients, respectively. CONCLUSION: Adrenal hemorrhage is secondary to multiple etiologies, most commonly trauma. In the setting of adrenal hemorrhage, many adrenal nodules were not identified on initial imaging. Only a minority of patients with nodules underwent "complete" biochemical evaluation. Follow-up imaging may improve the identification of underlying nodules needing hormonal evaluation.

Approach to the Patient With Bilateral Adrenal Masses.

Bilateral adrenal masses, increasingly encountered in clinical practice, manifest across diverse contexts, including incidental discovery, malignancy staging, and targeted imaging after hormonal diagnosis of adrenal disorders. The spectrum encompasses various pathologies, such as cortical adenomas, macronodular adrenal disease, pheochromocytomas, myelolipomas, infiltrative disorders, and primary and secondary malignancies. Notably, not all masses in both adrenal glands necessarily share the same etiology, often exhibiting diverse causes. Recently, the European Society of Endocrinology and the European Network for the Study of Adrenal Tumors updated guidelines, introduced a 4-option schema based on imaging, aiding in targeted hormonal testing and management. This "Approach to the Patient" review delves into the latest advancements in imaging, biochemical, and genetic approaches for the diagnostic and management nuances of bilateral adrenal masses. It provides insights and a contemporary framework for navigating the complexities associated with this clinical entity.

Imaging features of intra-abdominal and intra-pelvic causes of hirsutism.

Hirsutism is a relatively common disorder which affects approximately 5% to 15% of women. It is defined by excessive growth of terminal hair in women, which primarily affects areas dependent on androgens, such as the face, abdomen, buttocks, and thighs. Hirsutism can be caused by a variety of etiologies, which are most often not lifethreatening. However, in some cases, hirsutism can be an indicator of more serious underlying pathology, such as a neoplasm, which may require further elucidation with imaging. Within the abdomen and pelvis, adrenal and ovarian pathologies are the primary consideration. The goal of this manuscript is to review the etiologies and imaging features of various intra-abdominal and intra-pelvic causes of hirsutism.

[Xanthogranulomatous adrenalitis : A rare and difficult differential diagnosis of adrenal gland tumors]. / Xanthogranulomatöse Adrenalitis : Seltene und schwierige Differentialdiagnose von Nebennierentumoren.

A radiologically diagnosed tumor in a 29-year-old woman with a fever of around 39 °C was operated on under the suspicion of cholecystitis or a liver abscess. A solid tumor was found in the adrenal gland and resected. The frozen section findings did not reveal a clear diagnosis of entity and assignment. Histologically, the tumor was found to consist of densely clustered large histiocyte-like cells with expression of vimentin, CD68, and CD163 as well as negativity for keratin, langerin, and SMA. We diagnosed xanthogranulomatous adrenalitis and discussed the differential diagnoses (Langerhans cell histiocytosis, Rosai-Dorfman disease, malakoplakia, Erdheim-Chester disease).
