Acute adrenal insufficiency postoperatively is an uncommon problem and, if unrecognized, it may cause serious morbidity and can be fatal. It can occur as the result of acute bilateral adrenal hemorrhage associated with anticoagulation, inadvertent injury to or removal of a solitary adrenal gland, or postoperative stress in an individual with incipient adrenal insufficiency. Its manifestations, such as fever, tachycardia, hypotension, lethargy, abdominal pain and gastrointestinal dysfunction, mimic the other more common postoperative complications and compound the difficulty in establishing the correct diagnosis. Once the diagnosis is made the condition is readily managed successfully. We report 3 cases of acute adrenal insufficiency occurring after salvage cystectomy, ileal replacement of the ureter and retropubic prostatectomy, which illustrate the salient clinical features, problems in diagnosis and predisposing risk factors. All 3 patients survived once the diagnosis of adrenal insufficiency was made. These cases emphasize the need to be aware of the possibility of this complication to make the correct diagnosis and to institute proper treatment.

A 56-year-old man with persistently elevated liver enzyme levels, fatigue, lethargy and a 9.0 kg weight loss over six months underwent a percutaneous liver biopsy that demonstrated multiple granulomas. Screening serologies were positive for histoplasmosis, and he was started on itraconazole treatment. He returned to hospital the same night with coffee-ground emesis and in Addisonian crisis requiring parenteral steroids and intensive care unit support. An abdominal computed tomography scan revealed bilaterally enlarged, nonenhancing adrenal glands suggestive of infarcts, presumed secondary to histoplasmosis. Treatment was initiated with amphotericin B, and Histoplasma capsulatum was cultured from his urine and cerebrospinal fluid. A serum immunodiffusion test was also positive for both H and M bands, indicating active infection with Histoplasmosis species. His serum and urine samples were also weakly positive for the antigen. Despite complications of renal failure, pneumonia and congestive heart failure, he recovered with medical therapy and was discharged home to complete a prolonged course of itraconazole therapy. While hepatic granulomas often reflect an occult disease process, the cause may remain undiscovered in 30% to 50% of patients despite exhaustive investigations. H capsulatum is an uncommon cause of granulomatous liver disease, and with its protean clinical presentation, a high index of suspicion is needed to make the diagnosis and avoid the potentially high fatality rate associated with disseminated infection.

Addisonian crisis, also commonly referred to as adrenal crisis, occurs when the cortisol produced by the adrenal glands is insufficient to meet the body's acute needs. The symptoms are nonspecific and can mimic other processes, such as sepsis. Hypotension, lethargy, and fever can all be presenting signs. Secondary addisonian crisis can also result from pituitary apoplexy. Pituitary apoplexy usually occurs as hemorrhagic or ischemic necrosis in the presence of a pre-existing pituitary adenoma, and is a rare sequela of surgery. The symptoms of pituitary apoplexy are typically impressive and are relieved by urgent transsphenoidal decompression. Hypopituitarism resulting from pituitary apoplexy can be treated with exogenous hormones. The case presented herein illustrates occult pituitary apoplexy that occurred after on-pump coronary artery bypass grafting. In this patient, the initial signs of addisonian crisis were overlooked; however, once recognized, they were reduced dramatically with standard stress-dose cortisone. A suprasellar mass with a cystic component was found on magnetic resonance imaging. The hemorrhagic pituitary gland was treated by transsphenoidal decompression, which relieved the patient's bitemporal hemianopia and 6th-nerve palsy.

Acute adrenocortical insufficiency is a critical care emergency characterized by hemodynamic instability, lethargy, and cardiovascular collapse. Acute adrenal insufficiency has many etiologies, from rapid withdrawal of exogenous glucocorticoids to adrenocortical destruction to poor adrenal reserve after administration of steroid synthesis inhibitors. Etomidate, a parenteral hypnotic agent, is a steroid synthesis inhibitor. Although the use of continuous etomidate infusion in the intensive care unit fell from favor secondary to reports of adrenal crisis, single-dose etomidate for induction of anesthesia is common for the hemodynamically unstable patient or in patients who may not tolerate wide variance in heart rate or blood pressure. A case is presented of acute adrenocortical insufficiency and crisis after a standard induction dose of etomidate. Acute adrenal insufficiency should be suspected in intensive care unit patients who have undergone general anesthesia with etomidate induction and present with hypotension refractory to standard vasopressor administration.

Context. Pseudohypoaldosteronism type 1 (PHA1) is a life-threatening disease that causes severe hyperkalemia and cardiac arrest if not treated appropriately or if diagnosis is missed. Objective. To report a case of a newborn with vomiting and lethargy, ultimately diagnosed with pseudohypoaldosteronism. Patient. This case presented to the ED at an age of 14 days in hypovolemic shock. There was a family history of sudden infant death, her sister who was diagnosed with CAH and passed away at 3 months of age despite regular hormone replacement. Our patient had cardiac arrest in ED, due to hyperkalemia; while receiving fluid boluses, cardiopulmonary resuscitation was initiated. After stabilization, diagnostic workup demonstrated persistently low sodium, acidosis, and high potassium, which required peritoneal dialysis. Based on these findings, the patient was diagnosed with CAH. It turned out later that the patient had PHA1. Two years later, the patient had a new sibling with the same disease diagnosed at birth and started immediately on treatment without any complication. Conclusions and Outcome. This case highlights the significant diagnostic and therapeutic challenges in treating children with PHA1. Adrenal crisis is not always CAH; delayed diagnosis can lead to complication and even death. The presence of high plasma renin activity, aldosterone, and cortisol, along with the presence of hyponatremia and hyperkalemia, established the diagnosis of PHA type 1 and ruled out CAH.
