Lymphoma presenting with adrenal insufficiency. Adrenal enlargement on computed tomographic scanning as a clue to diagnosis.

A 73-year-old woman who presented with primary adrenal insufficiency and enlarged adrenal glands on computed tomographic scanning was ultimately found to have a large-cell lymphoma that had initially involved the adrenals and the stomach. A search of the English language medical literature revealed only seven other cases of lymphoma presenting with hypoadrenalism, none of which involved the stomach. As in this case, in most of those cases adrenal enlargement was documented on computed tomographic scanning. Despite its rare occurrence, lymphoma should be searched for in patients presenting with Addison's disease and enlarged adrenal glands.

Adrenal insufficiency.

Adrenal insufficiency is caused by either primary adrenal failure (mostly due to autoimmune adrenalitis) or by hypothalamic-pituitary impairment of the corticotropic axis (predominantly due to pituitary disease). It is a rare disease, but is life threatening when overlooked. Main presenting symptoms such as fatigue, anorexia, and weight loss are non-specific, thus diagnosis is often delayed. The diagnostic work-up is well established but some pitfalls remain, particularly in the identification of secondary adrenal insufficiency. Despite optimised life-saving glucocorticoid-replacement and mineralocorticoid-replacement therapy, health-related quality of life in adrenal insufficiency is more severely impaired than previously thought. Dehydroepiandrosterone-replacement therapy has been introduced that could help to restore quality of life. Monitoring of glucocorticoid-replacement quality is hampered by lack of objective methods of assessment, and is therefore largely based on clinical grounds. Thus, long-term management of patients with adrenal insufficiency remains a challenge, requiring an experienced specialist. However, all doctors should know how to diagnose and manage suspected acute adrenal failure.

Adrenal Insufficiency↗

[Adrenal insufficiency].

Adrenal insufficiency can be either primitive as the result of a destruction of the glands or secondary to a corticotropic failure. Adrenal insufficiency can appear as an acute event or in contrast arise progressively. An acute adrenal insufficiency can occur any time and threatens the vital prognosis. It should be prevented by adapted treatment and education of the patient. The treatment of adrenal insufficiency includes substitutive doses of mineralo and/or glucocorticoids and, as often as possible, etiologic therapy. For this reason, as soon as the diagnosis of adrenal insufficiency has been done, a main point is to determine the cause of the endocrine failure. Indeed, some diseases responsible for adrenal deficiency, among a progressively extending list of etiologic factors, can benefit for a specific treatment.

Acute Disease↗

Hypothalamic-pituitary-adrenal insufficiency.

Adrenal insufficiency is a common and underdiagnosed disorder that develops in critically ill patients. Most forms are acquired and will resolve with treatment of the underlying disease. Hypotension that is refractory to fluids and requires vasopressors is the most common presentation of adrenal insufficiency in the ICU. It is important to make the diagnosis of adrenal insufficiency, because current data suggest that treatment with glucocorticoids improves outcome. Diagnosis usually can be made on the basis of a stress cortisol level. Occasionally, when the level of stress is uncertain, the low-dose corticotropin stimulation test will be required for definitive diagnosis. A therapeutic trial with hydrocortisone should be started in patients with suspected adrenal insufficiency pending results of diagnostic testing.

Disseminated North American blastomycosis. Occurrence with clinical manifestations of adrenal insufficiency.

Adrenal involvement in cases of disseminated North American blastomycosis occurs frequently, but clinically substantive adrenal insufficiency is rare. An unusual case of disseminated blastomycosis with clinical manifestations of adrenal insufficiency was found. One should be alert to the symptoms of adrenal insufficiency that may develop in patients with disseminated mycoses.

Acute adrenal insufficiency.

Adrenal insufficiency is a rare disorder, usually with gradually evolving clinical symptoms and signs. Occasionally, an acute adrenal insufficiency crisis can become a life-threatening condition because of acute interruption of a normal or hyperfunctioning adrenal or pituitary gland or sudden interruption of a adrenal replacement therapy. Acute stress situations can aggravate the symptomatology. A simple strategy or diagnostic screening and early intervention with sodium chloride-containing fluids and hydrocortisone should be widely implemented for cases with suspicion of an acute Addison disease crisis. In contrast, the chronic replacement dosage for patients with adrenal insufficiency should be as low as possible with clear instructions for dosage adjustments in case of stress or acute emergencies.

Surgical management of isolated bilateral adrenal metastases from colon carcinoma causing adrenal insufficiency.

Adrenal insufficiency due to histologically proven bilateral metastatic adrenal involvement from colon cancer has been clinically reported only twice. Surgical treatment of bilateral adrenal metastases is seldom performed, since other metastatic localizations are usually concomitant. To the best of our knowledge, we report the first case of relatively long-term disease-free survival after bilateral adrenalectomy in a patient with adrenal insufficiency due to bilateral metastases from colon carcinoma.

Adrenal insufficiency after adrenal hemorrhage.

Acute adrenal hemorrhage (AAH) is an extremely rare disorder, especially in adults, and may be difficult to diagnose because of its nonspecific presentation. We report a case of AAH following a sepsis, resulting in persistant adrenal insufficiency contrasting with the radiologic normalisation of the adrenals on computed tomography (CT) scan imaging.

Adrenal insufficiency with enlarged adrenals.

Five patients with adrenal insufficiency and large adrenal glands at presentation are reported. Addison's disease was due to adrenal tuberculosis in three patients, with important changes in adrenal configuration on CT reflecting the natural history of the disease. Adrenal infiltration by non-Hodgkin lymphoma and metastatic carcinoma of the lung was the cause of the disease in the fourth and fifth patients, respectively, who developed signs of adrenal insufficiency before the diagnosis of the primary lesion became apparent. Histologic confirmation was established after unilateral adrenalectomy in three patients. In two patients with adrenal tuberculosis, long clinical and laboratory follow-up confirmed the diagnosis. This report indicates that Addison's disease is not infrequently associated with adrenal enlargement. Adrenal size is related to the cause and duration of the various disease states leading to adrenal insufficiency. Moreover, adrenal insufficiency associated with enlarged adrenal glands can be the presenting manifestation of lymphoma or metastasis.

[Acute adrenal insufficiency during unilateral adrenal hemorrhage secondary to the antiphospholipid syndrome].

INTRODUCTION: Acute adrenal insufficiency during antiphospholipid syndrome is usually due to a bilateral adrenal hemorrhage. For a patient, an unilateral involvement has induced an acute adrenal insufficiency. CASE REPORT: A patient with an antiphospholipid syndrome has developed an acute adrenal insufficiency with an unilateral adrenal hemorrhage. This complication was caused by a concurrent steroid therapy, for an associated lupus, which resulted in a suppression of the contralateral adrenal gland. CONCLUSION: In patients with antiphospholipid syndrome and concurrent steroid therapy, usually for lupus, unilateral adrenal hemorrhage can cause acute adrenal insufficiency. Withdrawal of steroid might be difficult in case of undetected bilateral hemorrhage.

Adrenal insufficiency from bilateral adrenal hemorrhage after total knee replacement surgery.

Adrenal hemorrhage is a rare cause of adrenal insufficiency in adults. We examine the incidence, etiology, diagnosis, and therapy of adrenal insufficiency secondary to adrenal hemorrhage. This case illustrates the nonspecific presentation of adrenal insufficiency and the necessity of maintaining a high index of suspicion in a clinically confusing scenario.
