Intense adrenal enhancement in patients with acute pancreatitis and early organ failure

Cross-sectional imaging features of unusual adrenal lesions: a radiopathological correlation

The detection rates of adrenal masses are increasing with the common and widespread use of cross-sectional imaging. Adrenal adenomas, myelolipomas, metastases, pheochromocytomas, and adrenocortical tumors are well-known and relatively common adrenal tumors. However, there are many less-known neoplastic and nonneoplastic adrenal diseases that might affect the adrenal glands in addition to these common lesions. These rare entities include, but are not limited to, hydatid cysts, congenital adrenal hyperplasia, Wolman disease, adrenal tuberculosis, primary adrenal lymphoma. This article aims to present imaging findings of these unusual lesions in accordance with their pathologic characteristics. We think that the simultaneous presentation of the pathological findings with the imaging features may facilitate the learning process and may potentially enhance the recognition of these entities.

Intense Adrenal Enhancement: A CT Feature of Cardiogenic Shock

In this report, images of intense adrenal enhancement in a 79-year-old female patient with right-sided heart failure and severe tricuspid insufficiency are presented. Only two cases of intense adrenal enhancement as a sign of cardiogenic shock were previously reported in the literature. Intense adrenal enhancement could be one of the earliest CT signs of cardiogenic shock. Its presence should be immediately reported to the referring physician as a sign of significant hemodynamic instability warranting early critical-care management.

The revised Atlanta classification for acute pancreatitis: a CT imaging guide for radiologists

Accurate diagnosis and description of the various findings in acute pancreatitis is important for treatment. The original Atlanta classification for acute pancreatitis sought to create a uniform system for classifying the severity of acute pancreatitis as well as common language to describe the various events that can occur in acute pancreatitis. The goal was to allow accurate communication between physicians using standardized language so correct treatment options could be used. Since that time, advances in the understanding of acute pancreatitis as well as improvements in both interventions and imaging have led to criticisms of the system and its abandonment by physicians. A 2007 revision of the Atlanta classifications sought to address many of these issues. This article will explain the changes to the Atlanta classification system and provide pictorial examples of the findings in acute pancreatitis as described by the Atlanta classification system.

The adrenocorticotropic hormone-induced cortisol response in acute pancreatitis

The evidence that severe acute pancreatitis can result in critical illness-related corticosteroid insufficiency following impaired adrenal secretion is accumulating. The study by Peng and coworkers in Critical Care certainly contributes to that idea, even though the question whether relative adrenal insufficiency should prompt for treatment by substitution doses of corticosteroids remains unresolved. The study is discussed in terms of the risk factors, circumstances and significance of impaired corticosteroid secretion by adrenals in severe acute pancreatitis.
