The Significance of Adrenal Hemorrhage: Undiagnosed Waterhouse-Friderichsen Syndrome, A Case Series

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.

Waterhouse-Friderichsen syndrome, septic adrenal apoplexy

Waterhouse-Friderichsen syndrome is a rare but potentially fatal disorder of the adrenal gland characterized by bilateral adrenal hemorrhage. It is classically a result of meningococcal sepsis and presents acutely with features of shock, petechial rashes, abdominal pain, and non-specific symptoms such as headache, fatigue, and vomiting. Treatment consists of fluid resuscitation, corticosteroid replacement, and possibly surgery. The prognosis is poor despite treatment. This chapter will review the etiology, pathogenesis, clinical features, and management of the disease.

Approach to the Patient With Adrenal Hemorrhage

Adrenal hemorrhage is an uncommon, underrecognized condition that can be encountered in several clinical contexts. Diagnosing adrenal hemorrhage is challenging due to its nonspecific clinical features. Therefore, it remains a diagnosis that is made serendipitously on imaging of acutely unwell patients rather than with prospective clinical suspicion. Adrenal hemorrhage can follow abdominal trauma or appear on a background of predisposing conditions such as adrenal tumors, sepsis, or coagulopathy. Adrenal hemorrhage is also increasingly reported in patients with COVID-19 infection and in the context of vaccine-induced immune thrombocytopenia and thrombosis. Unexplained abdominal pain with hemodynamic instability in a patient with a predisposing condition should alert the physician to the possibility of adrenal hemorrhage. Bilateral adrenal hemorrhage can lead to adrenal insufficiency and potentially fatal adrenal crisis without timely recognition and treatment. In this article, we highlight the clinical circumstances that are associated with higher risk of adrenal hemorrhage, encouraging clinicians to prospectively consider the diagnosis, and we share a diagnostic and management strategy.

Bilateral Adrenal Hemorrhage Following Femoral Hip Hemiarthroplasty: A Case Report

Bilateral adrenal hemorrhage (BAH) is a rare and potentially fatal complication following total hip arthroplasty and low-molecule heparin use for DVT-prophylaxis. We present a case of a 64-year-old woman who sustained a femoral neck fracture, which was addressed with hip hemiarthroplasty. Twelve days postoperatively DVT was diagnosed and therapeutic doses of low-molecule-heparin were administered. The next day, CTPA was done searching for pulmonary embolism but BAH was shown and a short synacthen test confirmed the diagnosis of adrenal insufficiency. A therapeutic protocol with hydrocortisone was followed.

Waterhouse-Friderichsen syndrome in a cat with Klebsiella spp. infection

OBJECTIVE

To describe a case of Waterhouse-Friderichsen syndrome of adrenocortical failure in a cat with Klebsiella spp. infection.

CASE SUMMARY

A 12-year-old male neutered domestic short-haired cat was referred for respiratory failure requiring mechanical ventilation. The cat remained comatose despite successful weaning from the ventilator and developed a Klebsiella pneumoniae pneumonia. On day 4 of hospitalization, the cat acutely deteriorated with profound hypotension, azotemia, and hyperkalemia, which rapidly progressed to cardiac arrest. Necropsy findings revealed massive adrenal hemorrhage and intralesional bacteria, termed Waterhouse-Friderichsen syndrome. Waterhouse-Friderichsen syndrome was suspected to have been the cause of acquired adrenocortical insufficiency and sudden death of the cat.

NEW OR UNIQUE INFORMATION

To the authors' knowledge, this is the first report of sepsis causing Waterhouse-Friderichsen syndrome in a veterinary species.

Fatal Waterhouse-Friderichsen syndrome in an adult due to serogroup Y Neisseria meningitidis

Waterhouse-Friderichsen syndrome (WFS), defined as severe adrenal insufficiency due to bilateral adrenal gland haemorrhagic necrosis, occurred in a 59-year-old woman. An underlying serogroup Y Neisseria meningitidis (NM) infection was diagnosed, with a rapid progression to purpura fulminans, disseminated intravascular coagulation and WFS. Intensive treatment including fluid resuscitation, broad-spectrum antibiotic therapy, ventilatory support, platelet and factor replacement were administered. The meningococcaemia in the presence of WFS had a fulminant progression, leading to a fatal outcome within 24 hours of symptom onset. This case details the diagnosis and management challenges of the WFS, a rare complication of NM septicaemia, and describes the identification of a NM serogroup that is rare in Portugal in middle-aged patients.

Bilateral adrenal haemorrhage complicated by sepsis, coagulopathy, influenza A and adrenal crisis

Bilateral adrenal haemorrhage is a rare and often fatal condition that most commonly occurs under conditions of severe physiological stress. We describe a 33-year-old male patient with ulcerative colitis who presented with acute worsening epigastric pain, vomiting and raised inflammatory markers. Initial differentials included gastritis and peptic ulceration. Gastroscopy revealed no abnormalities. By day 3, he had developed sepsis with a sequential organ failure assessment score of 2 as well as coagulopathy. A subsequent CT scan diagnosed bilateral adrenal haemorrhage. A short Synacthen Test confirmed adrenal insufficiency and he was treated with replacement steroids and antibiotics for a possible urinary tract infection or pyelonephritis and he recovered well. Several days later he developed fever, dyspnoea and a productive cough. Subsequently, he became hypotensive (Blood Pressure (BP) 95/65 mm Hg) and unresponsive with a Glasgow Coma Scale of 7 and was hyponatraemic and hyperkalaemic. He was intubated and transferred to a tertiary hospital for intensive care unit management where investigations confirmed the patient to be influenza A positive.

A Rare Case of Waterhouse-Friderichsen Syndrome Without Purpura Secondary to Haemophilus Influenzae

The Waterhouse-Friderichsen syndrome is an entity consisting of shock, petechial rash and haemorrhages in both adrenal glands leading to adrenal failure. This syndrome is usually secondary to meningococcal septicaemia, but there are many documented cases caused by other bacteria. Purpura is an essential part of the syndrome, but it is not always there. In the current study, a case of Waterhouse-Friderichsen syndrome without purpura in an elderly patient with Haemophilus influenzae bacteraemia has been described. This patient was being managed for sepsis due to pneumonia and an incidental finding of bilateral adrenal haemorrhage was made on a CT of the thorax which was meant to evaluate empyema. This case shows the need to suspect bilateral adrenal haemorrhage in every patient with septic shock.

Anticoagulation-induced unilateral adrenal haemorrhage and pseudoaneurysm

Spontaneous unilateral adrenal haemorrhage (AH) is extremely rare. Its presentation is usually non-specific and requires a high degree of suspicion as it is associated with high morbidity and mortality if diagnosis is delayed. Hereby, we present a case of 67-year-old man with significant cardiac history presented with right-sided chest pain and non-specific abdominal pain. He was previously treated for non-ST elevation myocardial infarction 5 days ago prior to the current presentation. CT scan of abdomen and pelvis demonstrated a right-sided active AH. The patient subsequently underwent digital subtraction angiography. Angio-embolisation was attempted for the pseudoaneurysm but failed due to spasm of the vessel. He was managed conservatively and discharged after clinical improvement. Clinic review 6 months later showed significant size reduction of the pseudoaneurysm.

Bilateral adrenal hemorrhage after hip arthroplasty: an initially misdiagnosed case

Background

Bilateral adrenal hemorrhage (BAH) is a rare but potentially catastrophic condition. Its clinical manifestation is often non-specific and sometimes difficult to be diagnosed in time.

Case summary

A 57-year-old woman, who presented with severe fatigue, nausea and vomiting after left hip arthroplasty due to her femoral neck fracture in a local hospital, was transferred to our medical center. Laboratory results revealed significant hyponatremia, low serum cortisol and elevated serum ACTH. Computed tomography (CT) showed a bilateral adrenal mass, measured 3.6 × 2.7 cm on the left and 3.4 × 2.3 cm on the right. Further magnetic resonance imaging (MRI) confirmed the diagnosis of BAH. The patient was prescribed with oral prednisolone acetate, 5 mg, tid, and her condition improved gradually. Nine months after, the patient was in good condition with 5 mg prednisolone acetate per day. CT revealed a clearly shrunken adrenal mass compared with 9 months ago.

Conclusions

This case illustrates the difficulty in making the diagnosis of BAH with atypical presentation. Such cases necessitate greater alertness on the part of the clinician and require rapid diagnosis and prompt glucocorticoid replacement for better clinical outcomes.

The Conundrum of Septic Shock Imitators in Patients with Hematologic Cancers: Case Presentation and Possible Differential Diagnoses

The authors describe the case of a patient treated with several cycles of chemotherapy due to an advanced stage non-Hodgkin lymphoma. One daafter the last cycle, he was admitted to our Intensive Care Unit with a septic shock-like clinical picture which didn't respond to the aggressive treatment and the patient died a few hours later. The autoptical findings cast some doubts on the diagnosis, and demonstrated the presence of other factors imitating its symptoms. In this article, the mimickers of septic shock are reviewed and discussed, as some of them require an aggressive immunosuppression instead of the recommended treatment for septic shock.

A unique fatal case of Waterhouse-Friderichsen syndrome caused by Proteus mirabilis in an immunocompetent subject: Case report and literature analysis

INTRODUCTION

The Waterhouse-Friderichsen syndrome (WFS), also known as purpura fulminans, is a potentially lethal condition described as acute hemorrhagic necrosis of the adrenal glands. It is often caused by infection. Classically, Neisseriae meningitidis represents the main microorganism related to WFS, although, infrequently, also other infectious agents are reported as a possible etiologic agent. The authors report the first case of death due to Proteus mirabilis infection, with postmortem evidence of WFS.

PATIENT CONCERNS

After a facial trauma that provoked a wound on the nose, the subject, a healthy 40-years old man, was conducted to the local hospital (in Sicily, Italy) after the primary care he was discharged. Subsequently, after 2 days of general malaise, he returned to the hospital due to the worsening of the clinical condition. During the hospitalization, hypotension, and neurological impairment appeared; the laboratory analysis showed leukocytosis and the alteration of renal, hepatic and coagulative parameters. Microbiological blood analysis resulted positive for a P mirabilis infection.

DIAGNOSIS

Multiorgan failure (MOF) with disseminated intravascular coagulation (DIC) due to sepsis was diagnosed.

INTERVENTIONS

The practitioners administered intensive support, antibiotic therapy, antithrombin III, vitamin K, and plasma.

OUTCOMES

After 3 days the subject died. The autopsy and the microscopic investigation were performed revealing, also, the adrenal diffuse micronodular hyperplasia associated with a cortico-medullary hemorrhagic apoplexy.

CONCLUSION

To our knowledge, this is the first case of MOF with WFS due to P mirabilis infection. This case report suggests that P mirabilis should be added to the list of unusual bacteria causing WFS. Furthermore, it supports the theory that any bacterium which causes DIC may cause adrenal hemorrhage and should suggest to clinicians the importance to consider a potential adrenal involvement in every patient with sepsis and DIC.

The importance of the postmortem interval for the diagnosis of Waterhouse-Friderichsen syndrome by Neisseria meningitidis in a series of forensic cases

The effective value of microbiological post-mortem examinations stands as fundamental in forensic cases involving microbiology. We ran these analyses on five victims, who suddenly died after showing persistent fever. The examinations were conducted between 48 hours and 10 days after death, and adrenal gland apoplexy was detected in all the cases.

Microbiological examinations identified Neisseria meningitidis, which was accountable for Waterhouse–Friderichsen syndrome. Diplococci were isolated from three cadavers that underwent forensic dissection between 2 and 3 days after death. The remaining two cadavers showed polymicrobial contamination, and a polymerase chain reaction technique was necessary to identify the pathogen.

We assumed that the microbial overlap could lead to diagnostic mistakes and conceal the identification of the lethal pathogen. Therefore, we suggest using molecular techniques for a postmortem interval (PMI) longer than 72 hours. Classical microbiological examination should be performed for PMI within 72 hours.

Acute non-traumatic adrenal haemorrhage-management, pathology and clinical outcomes

Background

Acute adrenal haemorrhage is a rare medical emergency. The aim of the series was to study the clinical presentation and management of patients presenting with acute non-traumatic adrenal haemorrhage.

Methods

The records of patients presenting with an acute abdomen secondary to adrenal haemorrhage and treated in a tertiary endocrine surgical unit over a period of 6 years were reviewed.

Results

Of the 11 included patients, there were 4 males and 7 females; the median [range] age at presentation was 58 [27-89] years. All were initially managed conservatively for bleeding, except one who underwent angioembolisation to ensure hemodynamic stability. Two patients underwent percutaneous drainage of persistent collection and suspected sepsis. Biochemical workup showed hyper function with metanephrine excess in 1 patient. Adrenalectomy was performed in 5 patients after a median [range] of 10 [7-11] weeks. Histology showed benign pathology in 2 patients, malignant in 2 patients and necrotic tumour in 1 patient. Two patients died of disseminated metastatic disease at 5 and 2 months after presentation with bleeding. Conservative management in the other 3 patients was successful at a median follow up of 26 [6-66] months.

Conclusions

Acute adrenal haemorrhage is usually associated with an underlying pathology; which may be benign or malignant; functional or non-functional. Initial conservative management is preferred as it allows determination of functional status and elective surgery, if necessary.

A Rare Case of Bilateral Adrenal Hemorrhage

Bilateral adrenal hemorrhage (BAH) is a rare but potentially fatal entity that carries a mortality rate of 15%. Most cases are associated with sepsis, antiphospholipid syndrome, the use of anticoagulants, as well as trauma and surgery. In this case report, we present a case of BAH in a previously healthy man with a recent history of corticosteroid use. Our case emphasizes the ambiguous clinical presentation of BAH, which poses a challenge in the establishment of a correct diagnosis. We also illustrate the pathophysiology, diagnosis, and subsequent therapeutic approach to this rare clinical entity.

Fulminant group A streptococcal infection without gangrene in the extremities: Analysis of five autopsy cases

Five autopsy cases of fulminant group A streptococcal infection without gangrene in the extremities are presented. Clinical course of the fulminant illness was short (2-4 days). One pathological autopsy case was aged (86-years-old), and hemorrhagic cystitis was observed. The other four forensic autopsy cases were young (24-38 years-old) with the mean age of 32, and the primary infective lesions were located in the postpartum endometrium, tonsil and bronchus (2 cases). Systemic coccal dissemination with poor neutrophilic reaction was seen in two of five cases. Bilateral renal cortical necrosis was noted in three cases (including two with bacterial embolism). Hemophagocytosis, probably resulting from hypercytokinemia, was characteristic in three cases without bacterial embolism. Gram-positive cocci colonizing the hemorrhagic and necrotizing lesions were consistently immunoreactive for streptococcal antigens and Strep A (a carbohydrate antigen on group A streptococci). Neutrophilic reaction was mild in the primary infected foci. Clinicians should note that fulminant streptococcal infection (streptococcal toxic shock syndrome) in young and immunocompetent patients may not be associated with gangrene in the extremities. Autopsy prosecutors (diagnostic and forensic pathologists) must recognize the difficulty in making an appropriate autopsy diagnosis, particularly when bacterial embolism is not associated.

Hydrocortisone therapy in a cat with vasopressor-refractory septic shock and suspected critical illness-related corticosteroid insufficiency

A 27‐month‐old female cat was presented with septic peritonitis secondary to a ruptured pyometra and subsequent pyothorax. Vasopressor‐refractory septic shock led to a suspicion of critical illness‐related corticosteroid insufficiency, successfully treated with intravenous hydrocortisone. Previous megestrol acetate administration may have played a role in the development of adrenocortical dysfunction.

Streptococcus Pneumoniae Detection Long Time After Death in a Fatal Case of Waterhouse-Friderichsen Syndrome

We report a fatal case of Waterhouse-Friderichsen syndrome in a 64-year-old man. The diagnosis, suspected during the autopsy (performed 63 hours after death), was confirmed through the successful detection of Streptococcus pneumoniae DNA and antigens in samples (blood and liver) collected during the autopsy. These results conformed with blood cultures performed antemortem, which became available only the day after the autopsy. The case underlines the need to collect biological material (liver and blood samples) during autopsy for microbiological investigations, although the collection is performed a long time after the death, suggesting that a liver sample works for DNA and liver and blood work for Streptococcus pneumoniae antigen detection.

Adrenal crisis secondary to bilateral adrenal haemorrhage after hemicolectomy

Adrenal haemorrhage is a rare cause of adrenal crisis, which requires rapid diagnosis, prompt initiation of parenteral hydrocortisone and haemodynamic monitoring to avoid hypotensive crises. We herein describe a case of bilateral adrenal haemorrhage after hemicolectomy in a 93-year-old female with high-grade colonic adenocarcinoma. This patient's post-operative recovery was complicated by an acute hypotensive episode, hypoglycaemia and syncope, and subsequent computed tomography (CT) scan of the abdomen revealed bilateral adrenal haemorrhage. Given her labile blood pressure, intravenous hydrocortisone was commenced with rapid improvement of blood pressure, which had incompletely responded with fluids. A provisional diagnosis of hypocortisolism was made. Initial heparin-induced thrombocytopenic screen (HITTS) was positive, but platelet count and coagulation profile were both normal. The patient suffered a concurrent transient ischaemic attack with no neurological deficits. She was discharged on a reducing dose of oral steroids with normal serum cortisol levels at the time of discharge. She and her family were educated about lifelong steroids and the use of parenteral steroids should a hypoadrenal crisis eventuate.

LEARNING POINTS

Adrenal haemorrhage is a rare cause of hypoadrenalism, and thus requires prompt diagnosis and management to prevent death from primary adrenocortical insufficiency.Mechanisms of adrenal haemorrhage include reduced adrenal vascular bed capillary resistance, adrenal vein thrombosis, catecholamine-related increased adrenal blood flow and adrenal vein spasm.Standard diagnostic assessment is a non-contrast CT abdomen.Intravenous hydrocortisone and intravenous substitution of fluids are the initial management.A formal diagnosis of primary adrenal insufficiency should never delay treatment, but should be made afterwards.

Adrenal insufficiency due to the development of bilateral adrenal haemorrhage following hip replacement surgery

Bilateral adrenal haemorrhage should be considered as a differential diagnosis in patients presenting with non-specific symptoms and hypotension postoperatively.

Traumatic and non-traumatic adrenal emergencies

Multiple traumatic and non-traumatic adrenal emergencies are occasionally encountered during the cross-sectional imaging of emergency department patients. Traumatic adrenal hematomas are markers of severe polytrauma, and can be easily overlooked due to multiple concomitant injuries. Patients with non-traumatic adrenal emergencies usually present to an emergency department with a non-specific clinical picture. The detection and management of adrenal emergencies is based on cross-sectional imaging. Adrenal hemorrhage, adrenal infection, or rupture of adrenal neoplasm require immediate detection to avoid dire consequences. More often however, adrenal emergencies are detected incidentally in patients being investigated for non-specific acute abdominal pain. A high index of suspicion is required for the establishment of timely diagnosis and to avert potentially life-threatening complications. We describe cross-sectional imaging findings in patients with traumatic and non-traumatic adrenal hemorrhage, adrenal infarctions, adrenal infections, and complications of adrenal masses.

Post-operative bilateral adrenal haemorrhage: A case report

•

An unusual complication of intra-abdominal sepsis.

•

A demonstration of diagnostic difficulty in the post-operative patient.

•

A variation from the normal electrolyte profile observed in adrenal insufficiency.

•

Highlights the clinical importance of a high index of suspicion for further investigation of ‘on-ward’ electrolyte abnormalities.

INTRODUCTION

Bilateral adrenal haemorrhage is a rare, but serious, illness carrying an estimated 15% mortality.^1,2 The majority of cases occur in patients with acute, stressful illness, however the exact mechanism underlying adrenal haemorrhage remains unclear. This medical emergency carries significant diagnostic difficulty⁴ with non-specific clinical symptoms and variations in electrolyte abnormalities. Timely treatment is important as it prevents both the acute and long-term sequelae of adrenal failure.

PRESENTATION OF CASE

This report describes a medical emergency in a surgical patient following emergency surgery for intra-abdominal sepsis. The patient reported non-specific symptoms of confusion, mild pyrexia and vague abdominal pain during the post-operative phase, with subtle electrolyte abnormalities and a low serum cortisol suggestive of adrenal crisis. Timely medical treatment, with intravenous hydrocortisone and intensive monitoring, and appropriate medical follow-up with addition of long-term fludrocortisone resulted in a satisfactory outcome.

DISCUSSION

This report describes a potentially life-threatening complication of intra-abdominal sepsis with adrenal crisis secondary to bilateral adrenal haemorrhage. In particular, this case highlights the diagnostic difficulty in such surgical patients due to vague symptoms and, in this case, the presence of a presentation variant with acute hyponatraemia and normal potassium.

CONCLUSION

This case highlights the importance of awareness of both the symptoms and signs and variation in electrolyte profile when assessing surgical patients post-operatively. In addition, this case highlights the benefit of early recognition and initiation of treatment and the importance of follow-up as long-term medical management is often required to prevent further relapse.

Tuberculosis of the adrenal gland: a case report and review of the literature of infections of the adrenal gland

Infections of the adrenal glands remain an important cause of adrenal insufficiency, especially in the developing world. Indeed, when Thomas Addison first described the condition that now bears his name over 150 years ago, the vast majority of cases were attributable to tuberculosis. Here we describe a classic, but relatively uncommon, presentation in the United States of adrenal insufficiency followed by a review of the current literature pertaining to adrenal infections.
