Magnetic Resonance Imaging of the Adrenal Gland and Kidney

The results of examination and treatment of 647 patients with endogenous hypercortisolism were studied: pituitary corticotropinoma was detected in 494 (76.4%) patients, corticosteroma and pre corticosteroma of the adrenal gland in 142 (21.9%), bilateral macro-nodular hyperplasia of the adrenal glands of primary adrenal origin-in 11 (1.7%). Differential diagnosis of clinical forms of endogenous hypercortisolism was based on the assessment of the level of adrenocorticotropic hormone and cortisol, both in peripheral blood, and with selective bilateral blood sampling from the adrenal veins and lower stony sinuses, and the study of the nature of samples with 8 mg of dexamethasone. Topical diagnostics consisted in assessing the state of the adrenal glands and pituitary gland during computed tomography and magnetic resonance imaging with the use of contrast agents, and the use of special software 3D-Volume Rendering Technique allowed optimizing tactical and technical approaches to performing surgical interventions. Of the operated patients with adrenocorticotropic hormone dependent endogenous hypercortisolism, total removal according to the control magnetic resonance imaging was achieved in 92.3% of cases, subtotal in 7.7%. However, hormonal remission was achieved only in 82.4% of cases. All patients with corticosteroma and pre-corticosteroma of the adrenal gland underwent adrenalectomy: in 6 patients by open method, in 136 patients by endovideosurgical method (in 11 patients by laparoscopic method, in 124 patients by retroperitoneoscopic method, and in 1 patient by thoracoscopic transdiaphragmatic adrenalectomy). In all patients, the operation led to recovery. Patients with benign macronodular hyperplasia of the adrenal glands needed conservative treatment with steroidogenesis blockers. Indications for surgical treatment in the volume of unilateral adrenalectomy occurred only in 2 patients.

Severe Health Problem

AbstractAlveolar echinococcus (AE) is a severe health problem in endemic areas. In recent years, the incidence of this disease in China has been increasing. The study was designed to illustrate the multi-slice computed tomography (MSCT) and magnetic resonance imaging (MRI) features of extrahepatic AE. A cohort of 33 patients who suffered from extrahepatic AE was enrolled consecutively from January 2012 to December 2017. The MSCT and MRI features of extrahepatic AE were recorded and analyzed by experienced radiologists. All cases secondary to hepatic AE, except two primary extrahepatic AE, were found in this study. Locations of extrahepatic AE included 19 (57.6%) lung, 10 (30.3%) adrenal gland, 9 (27.3%) brain, 5 (15.2%) peritoneal cavity, 5 (15.2%) spleen, 4 (12.1%) diaphragm, 3 (9.1%) kidney, 3 (9.1%) retroperitoneal, and 2 (6.1%) vertebra; Involvement of 1 (3.0%) heart, 1 (3.0%) mediastinum, 1 (3.0%) muscle, and 1 (3.0%) pancreas was rare. AE of the lung usually appeared as irregular and scattered nodules with small vacuoles or cavities inside and peripheral distribution. Multiple cerebral nodules with calcification and surrounding edema were the most common features seen in brain AE. Adrenal gland AE presented as plaques containing different sizes of hypodense areas and different amounts of calcification. Injection of contrast medium showed no enhancement of lesions except in the brain. MSCT and MRI are reliable imaging methods for the diagnosis of extrahepatic AE. When one AE patient is clinically confirmed, MSCT scan from the chest to the abdomen should be performed to exclude other organs AE.

Abstract Background. Alveolar echinococcus (AE) is a severe health problem in endemic areas. In recent years, the incidence of this disease in China has been increasing. The study was designed to illustrate the multi-slice computed tomography (MSCT) and magnetic resonance imaging (MRI) features of extrahepatic AE.Methods. A cohort of 33 patients who suffered from extrahepatic AE was enrolled consecutively from January 2012 to December 2017. The MSCT and MRI features of extrahepatic AE were recorded and analyzed by experienced radiologists. The MSCT and MRI agreements for detecting imaging features of extrahepatic AE were calculated using kappa statistics.Results. All cases secondary to hepatic AE, except two primary extrahepatic AE, were found in this study. Locations of extrahepatic AE included 19 (57.6%) lung, 10 (30.3%) adrenal gland, 9 (27.3%) brain, 5 (15.2%) peritoneal cavity, 5 (15.2%) spleen, 4 (12.1%) diaphragm, 3 (9.1%) kidney, 3 (9.1%) retroperitoneal, and 2 (6.1%) vertebra; Involvement of 1 (3.0%) heart, 1 (3.0%) mediastinum, 1 (3.0%) muscle, and 1 (3.0%) pancreas was rare. AE of the lung usually appeared as irregular and scattered nodules with small vacuoles or cavities inside and peripheral distribution. Multiple cerebral nodules with calcification and surrounding edema were the most common features seen in brain AE. Adrenal gland AE presented as plaques containing different sizes of hypodense areas and different amounts of calcification. Injection of contrast medium showed no enhancement of lesions except in the brain. Very good agreements were seen between MSCT and MR for detecting number (κ=0.841, p=0.000), border (κ=0.911, p=0.000) and size (κ=0.864, p=0.000) of extrahepatic AE.Conclusions. MSCT and MRI are reliable imaging methods for the diagnosis of extrahepatic AE. When one AE patient is clinically confirmed, MSCT scan from the head to pelvis should be performed to exclude other organs AE.
