Association between anatomic variations of extrahepatic and intrahepatic bile ducts: Do look up! J Anat 2023; 242:683-694. [PMID: 36670522 PMCID: PMC10008292 DOI: 10.1111/joa.13808] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Revised: 12/06/2022] [Accepted: 12/06/2022] [Indexed: 01/22/2023] Open
Abstract
Biliary anatomic variations are usually asymptomatic, but they may cause problems in diagnostic investigations and interventional and surgical procedures, increasing both their technical difficulty and their postoperative complication rates. The aim of the present study was to evaluate the prevalence of anatomic variations in the intrahepatic biliary ducts (IHBD) in relation to demographical and clinical characteristics in a large study population requiring magnetic resonance cholangiopancreatography (MRCP) for various clinical conditions. The possible association between IHBD and extrahepatic biliary ducts (EHBD) variants was then explored. From January 2017 to May 2019, 1004 patients underwent MRCP. Demographical and clinical data were collected. IHBD and EHBD anatomy were recorded and the EHBD anatomy was classified using both qualitative and quantitative classifications. The presence of a type 3 EHBD variant (an abnormal proximal cystic duct [CD] insertion) in both qualitative and quantitative classifications and an intrapancreatic CD were associated with the presence of IHBD variants at univariate analysis (p = 0.008, p = 0.019, and p = 0.001, respectively). The presence of a posterior or medial insertion of the CD into the EHBD was a strong predictive factor of the presence of IHBD variants both at uni- and multivariate analysis (p = 0.002 and p = 0.003 for posterior insertion and p = 0.002 and p = 0.002 for medial insertion, respectively). The presence of gallstones on MRCP resulted in a strong predictor of the presence of an anatomical variant of the IHBD both at uni- and multivariate analysis (p = 0.027 and p = 0.046, respectively). In conclusion, the presence of a type 3 variant of the EHBD, an intrapancreatic CD and, especially, a posterior/medial CD insertion into the EHBD represent predictive factors of the concomitant presence of IHBD variants, thus radiologists must be vigilant when encountering these EHBD configurations and always remember to "look up" at the IHBD. Finally, the presence of an IHBD variant is a strong predictive factor of gallstones.

Mild autonomous cortisol secretion in adrenal incidentalomas and risk of fragility fractures: a large cross-sectional study. Eur J Endocrinol 2023; 188:343-352. [PMID: 36952249 DOI: 10.1093/ejendo/lvad038] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Revised: 03/07/2023] [Accepted: 03/22/2023] [Indexed: 03/24/2023]
Abstract
OBJECTIVE Mild autonomous cortisol secretion (MACS) has been associated with a higher prevalence of osteoporosis, although most data rely on single-center studies with limited sample size. We aimed to assess the prevalence of fragility fractures and contributing factors in a large cohort of patients with adrenal incidentalomas. DESIGN AND METHODS Medical records of 1023 patients with adrenal incidentalomas from 1990 to 2019 were reviewed, and 735 patients were selected. Clinically-obtained electronic radiological images closest to first endocrine evaluation, such as lateral views of spine X-rays or CT thoraco-abdominal scans, were reviewed to screen for asymptomatic morphometric vertebral fractures. Clinical fragility fractures, hormonal and DXA indices were also recorded. RESULTS 474 patients had non-functioning (NF) adrenal incidentalomas, 238 had MACS and 23 Adrenal Cushing's Syndrome (AC). Prevalence of fragility fractures was different (P = 0.018) between groups, respectively 24.1% (NF), 34.0% (MACS) and 30.4% (AC), with significant difference between NF and MACS (P = 0.012). When analyzed separately by sex and menopausal status, this difference remained significant in post-menopausal women (P = 0.011), with a fracture prevalence of 22.2% (NF), 34.6% (MACS). Fracture prevalence was similar in males. Women with MACS aged ≥65 years reported a 48.8% prevalence of fractures, as compared with 29.5% in NF (P < 0.01). In post-menopausal women, fragility fractures were associated with age (OR 1.1, P < 0.001), smoking (OR 1.8, P = 0.048) and 1mg-DST cortisol (OR 3.1, P = 0.029), while in men, only age was associated with fragility fractures. CONCLUSIONS A considerable fracture burden was shown in post-menopausal women with adrenal incidentalomas and MACS, with clinical implications for the evaluation and management of bone metabolism.

Computerized tomography texture analysis of pheochromocytoma: relationship with hormonal and histopathological data. J Endocrinol Invest 2022; 45:1935-1944. [PMID: 35680695 PMCID: PMC9463266 DOI: 10.1007/s40618-022-01826-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2021] [Accepted: 05/17/2022] [Indexed: 11/29/2022]
Abstract
OBJECTIVES Pheochromocytomas are rare tumors which can present with heterogeneous secretion profiles, clinical manifestations, and radiologic appearance. Under a histopathological point of view, they can be characterized as more or less aggressive with the Pheochromocytoma of the Adrenal gland Scaled Score (PASS) and the Grading system for Adrenal Pheochromocytoma and Paraganglioma (GAPP) score. The aim of this study is to analyze the texture analysis characteristics of pheochromocytoma and identify whether the texture analysis can yield information aiding in the diagnosis and the characterization of those tumors. METHODS Radiological, biochemical, and histopathological data regarding 30 consecutive patients with histologically confirmed pheochromocytoma were analyzed. Images obtained in the unenhanced, late arterial, venous, and delayed phases were used for the texture analysis. RESULTS Urinary epinephrine and metanephrine levels showed a significant correlation (R2 = 0.946; R2 = 699) in the multivariate linear model with texture features, as well as Ki-67 (R2 = 0.397), PASS score (R2 = 0.182), GAPP score (R2 = 0.705), and cellularity showed a significant correlation (R2 = 0.389). The cluster analysis based on radiomic features resulted in 2 clusters, with significative differences in terms of systolic and diastolic blood pressure values at the time of diagnosis (p = 0.025), GAPP score (4 vs 6, p = 0.05), histological pattern (1-2, p = 0.039), and comedonecrosis (0% vs 50%, p = 0.013). CONCLUSION In conclusion, our study provides the proof of concept for the use of texture analysis on contrast-enhanced CT images as a noninvasive, quantitative tool for helping in the characterization of the clinical, biochemical, and histopathological features of pheochromocytoma.

An Imaging Overview of COVID-19 ARDS in ICU Patients and Its Complications: A Pictorial Review. Diagnostics (Basel) 2022; 12:846. [PMID: 35453894 PMCID: PMC9032937 DOI: 10.3390/diagnostics12040846] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Revised: 03/23/2022] [Accepted: 03/28/2022] [Indexed: 01/08/2023] Open
Abstract
A significant proportion of patients with COVID-19 pneumonia could develop acute respiratory distress syndrome (ARDS), thus requiring mechanical ventilation, and resulting in a high rate of intensive care unit (ICU) admission. Several complications can arise during an ICU stay, from both COVID-19 infection and the respiratory supporting system, including barotraumas (pneumothorax and pneumomediastinum), superimposed pneumonia, coagulation disorders (pulmonary embolism, venous thromboembolism, hemorrhages and acute ischemic stroke), abdominal involvement (acute mesenteric ischemia, pancreatitis and acute kidney injury) and sarcopenia. Imaging plays a pivotal role in the detection and monitoring of ICU complications and is expanding even to prognosis prediction. The present pictorial review describes the clinicopathological and radiological findings of COVID-19 ARDS in ICU patients and discusses the imaging features of complications related to invasive ventilation support, as well as those of COVID-19 itself in this particularly fragile population. Radiologists need to be familiar with COVID-19's possible extra-pulmonary complications and, through reliable and constant monitoring, guide therapeutic decisions. Moreover, as more research is pursued and the pathophysiology of COVID-19 is increasingly understood, the role of imaging must evolve accordingly, expanding from the diagnosis and subsequent management of patients to prognosis prediction.

Association Between Aldosterone and Parathyroid Hormone Levels in Patients With Adrenocortical Tumors. Endocr Pract 2021; 28:90-95. [PMID: 34508903 DOI: 10.1016/j.eprac.2021.09.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2021] [Revised: 09/01/2021] [Accepted: 09/03/2021] [Indexed: 11/19/2022]
Abstract
OBJECTIVE Patients with primary aldosteronism (PA) can present with high PTH levels and negative calcium balance, with some studies speculating that aldosterone could directly stimulate PTH secretion. Either adrenalectomy or mineralocorticoid receptor blockers could reduce PTH levels in patients with PA. The aim of this study was to assess the relationship between aldosterone levels and parathyroid hormone (PTH)-vitamin D-calcium axis in a cohort of patients with PA, compared with patients with nonsecreting adrenocortical tumors in conditions of vitamin D sufficiency. METHODS We enrolled a series of 243 patients retrospectively, of whom 66 had PA and 177 had nonsecreting adrenal tumors, and selected those with full mineral metabolism evaluation and 25(OH) vitamin D levels >20 ng/mL at the time of initial endocrine screening. The final cohort was composed of 26 patients with PA and 39 patients, used as controls, with nonsecreting adrenal tumors. The relationships between aldosterone, PTH levels, and biochemistries of mineral metabolism were assessed. RESULTS Aldosterone was positively associated with PTH levels (r = 0.260, P < .05) in the whole cohort and in the PA cohort alone (r = 0.450; P = .02). In the multivariate analysis, both aldosterone concentrations and urinary calcium excretion were significantly related to PTH levels, with no effect of 25(OH) vitamin D or other parameters of bone metabolism. CONCLUSION PTH level is associated with aldosterone, probably independent of 25(OH) vitamin D levels and urinary calcium. Whether aldosterone interacts directly with the parathyroid glands remains to be established.

Imaging-based diagnosis of benign lesions and pseudolesions in the cirrhotic liver. Magn Reson Imaging 2021; 75:9-20. [PMID: 32926993 DOI: 10.1016/j.mri.2020.09.008] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2020] [Revised: 09/07/2020] [Accepted: 09/08/2020] [Indexed: 02/07/2023]
Abstract
Liver cirrhosis is a leading cause of death worldwide, with 1-year mortality rates of up to 57% in decompensated patients. Hepatocellular carcinoma (HCC) is the most common primary tumor in cirrhotic livers and the second leading cause of cancer-related mortality worldwide. Annually, up to 8% of patients with cirrhosis develop HCC. The diagnosis of HCC rarely requires histological confirmation: in fact, according to the most recent guidelines, the imaging features of HCC are almost always sufficient for a certain diagnosis. Thus, the role of the radiologist is pivotal because the accurate detection and characterization of focal liver lesions in patients with cirrhosis are essential in improving clinical outcomes. Despite recent technical innovations in liver imaging, several issues remain for radiologists regarding the differentiation of HCC from other hepatic lesions, particularly benign lesions and pseudolesions. It is important to avoid misdiagnosis of benign liver lesions as HCC (false-positive cases) because this diagnostic misinterpretation may lead to ineligibility of a patient for potentially curative treatments or inappropriate assignment of high priority scores to patients on waiting lists for liver transplantation. This review presents a pocket guide that could be useful for the radiologist in the diagnosis of benign lesions and pseudolesions in cirrhotic livers, highlighting the imaging features that help in making the correct diagnosis of macroregenerative nodules; siderotic nodules; arterioportal shunts; hemangiomas, including fast-filling hemangiomas, hemangiomas with pseudowashout, and sclerosed hemangiomas; confluent fibrosis; pseudomasses in chronic portal vein thrombosis; and focal fatty changes.

Radiologically defined lipid-poor adrenal adenomas: histopathological characteristics. J Endocrinol Invest 2020; 43:1197-1204. [PMID: 32062826 DOI: 10.1007/s40618-020-01198-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2019] [Accepted: 02/10/2020] [Indexed: 12/21/2022]
Abstract
BACKGROUND Adrenal lipid-poor adenomas (LPA) are defined by high unenhanced density (≥ 10 HU), and absolute and relative contrast medium washout > 60% and > 40%, respectively, at computerized tomography (CT). To date, no thorough histopathological characterization has been performed in those frequent lesions (one-third of adrenal adenomas). Our aim was to analyze the histopathological characteristics of adrenal LPA. METHODS Patients with LPA (n = 57) were selected among consecutive subjects referred for an adrenal incidentaloma or ACTH-independent Cushing syndrome. FluoroDeoxyGlucose-Positron Emission Tomography (FDG-PET) was performed in 37 patients. In patients treated by adrenalectomy (n = 17), Weiss score and Lin-Weiss-Bisceglia score (in tumors composed entirely or predominantly of oncocytes) were calculated. RESULTS Radiological parameters did not differ among patients with ACTH-independent Cushing syndrome (n = 6) and those with adrenal incidentalomas associated with primary aldosteronism (n = 2), autonomous cortisol secretion (n = 14), or non-functioning (n = 35). Patients treated by adrenalectomy had larger tumors (28.9 ± 11.2 vs 17.3 ± 8.4 mm, P < 0.001), higher CT unenhanced density (29.1 ± 11.0 vs 23.1 ± 9.0 HU, P = 0.043), and FDG-PET adrenal uptake (9.0 ± 6.4 vs 4.4 ± 2.3 SUV, P = 0.003) than non-operated ones. Oncocytic features > 75% of the tumor were detected in 12/17 cases (70.6%). Five of those showed borderline-malignant histopathological characteristics by Lin-Weiss-Bisceglia score. Among remaining non-oncocytic tumors, 1/5 had a Weiss score ≥ 3. Overall, 6/17 tumors (35.3%) had borderline-malignant potential. Radiological parameters were similar between patients with benign and borderline-malignant tumors. CONCLUSIONS Adrenal LPA are a heterogeneous group of tumors, mostly composed of oncocytomas. Up to 1/3 of those tumors may have a borderline-malignant potential at histopathology.

Diagnostic Accuracy of North America Expert Consensus Statement on Reporting CT Findings in Patients Suspected of Having COVID-19 Infection: An Italian Single-Center Experience. Radiol Cardiothorac Imaging 2020; 2:e200312. [PMID: 33778611 PMCID: PMC7380122 DOI: 10.1148/ryct.2020200312] [Citation(s) in RCA: 28] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2020] [Revised: 07/09/2020] [Accepted: 07/10/2020] [Indexed: 12/23/2022]
Abstract
PURPOSE To evaluate the diagnostic accuracy of the four standardized categories for CT reporting proposed by the Radiological Society of North America (RSNA) to support a faster triage compared with real-time reverse-transcription polymerase chain reaction (RT-PCR), which is the reference standard for suspected coronavirus disease 2019 (COVID-19), but has long reporting time (6-48 hours). MATERIALS AND METHODS A retrospective analysis of 569 thin-section CT examinations performed for patients suspected of having COVID-19 from February 27 to March 27, 2020 (peak of infection in Italy) was conducted. The imaging pattern was classified according to the statement by the RSNA as "typical," "indeterminate," "atypical," and "negative" and compared with RT-PCR for 460 patients. Interobserver variability in reporting between a senior and a junior radiologist was evaluated. Use of the vascular enlargement sign in indeterminate cases was also assessed. RESULTS The diagnosis of COVID-19 was made in 45.9% (211/460) of patients. The "typical" pattern (n = 172) showed a sensitivity of 71.6%, a specificity of 91.6%, and a positive predictive value of 87.8% for COVID-19. The "atypical" (n = 67) and "negative" (n = 123) pattern demonstrated a positive predictive value of 89.6% and 86.2% for non-COVID-19, respectively. The "indeterminate" (n = 98) pattern was nonspecific, but vascular enlargement was most frequently found in patients with COVID-19 (86.1%; P < .001). Interobserver agreement was good for the "typical" and "negative" pattern and fair for "indeterminate" and "atypical" (κ = 0.5; P = .002). CONCLUSION In an epidemic setting, the application of the four categories proposed by the RSNA provides a standardized diagnostic hypothesis, strongly linked to the RT-PCR results for the "typical," "atypical," and "negative" pattern. In the "indeterminate" pattern, the analysis of the vascular enlargement sign could facilitate the interpretation of imaging features.© RSNA, 2020.

Abstract
CONTEXT Chronic glucocorticoids excess leads to morphological and functional cardiac alterations, a substrate for arrhythmias. Autonomous cortisol secretion (ACS) in adrenal incidentalomas is a model of chronic endogenous hypercortisolism. OBJECTIVE To investigate prevalence and incidence of atrial fibrillation (AF) in a large cohort of patients with ACS. DESIGN Retrospective study. SETTING University hospital. PATIENTS Patients evaluated between 1990 and 2018 for adrenal incidentalomas (n = 632), without pheochromocytoma, primary aldosteronism, Cushing syndrome, congenital adrenal hyperplasia, and adrenal malignancy. Cortisol after 1-mg dexamethasone suppression test < or > 50 nmol/L defined nonsecreting tumors (NST) (n = 420) and ACS (n = 212), respectively. INTERVENTION Assessment of AF at baseline (n = 632) and during a median follow-up of 7.7 years retrospectively (NST, n = 249; ACS, n = 108). Comparison with general population. MAIN OUTCOME MEASURE Prevalence and incidence of AF. RESULTS AF prevalence was higher in patients with ACS (8.5%) than NST (3.1%, P = 0.003) and the general population (1.7%; P < 0.001 vs ACS, P = 0.034 vs NST). The age-adjusted rate ratio to the general population was 1.0 for NST and 2.6 for ACS. AF was associated with ACS (odds ratio, 2.40; 95% confidence interval [CI], 1.07-5.39; P = 0.035). The proportion of patients with AF at last evaluation was higher in ACS (20.0%) than NST (11.9%; P = 0.026). ACS showed a higher risk of incident AF than NST (hazard ratio, 2.95; 95% CI, 1.27-6.86; P = 0.012), which was associated with post-dexamethasone cortisol (hazard ratio, 1.15; 95% CI, 1.07-1.24; P < 0.001), independently of known contributing factors. CONCLUSIONS Patients with adrenal incidentalomas and ACS are at risk of AF. Electrocardiogram monitoring may be recommended during follow-up.

Abstract
CONTEXT Steroid profiling by mass spectrometry has shown implications for diagnosis and subtyping of adrenal tumors. OBJECTIVES To investigate steroid profiles and their cardiovascular correlates in a large cohort of patients with nonsecreting (NS) adrenal incidentalomas and autonomous cortisol secretion (ACS). DESIGN Cohort study. SETTING University hospital. PATIENTS Patients (n = 302) with incidentally discovered adrenal masses, divided into unilateral adenoma and hyperplasia with ACS (n = 46 and n = 52, respectively) and NS (n = 120 and n = 84, respectively). Post-dexamethasone suppression test (DST) cortisol <50 or >50 nmol/L defined NS and ACS, respectively. INTERVENTION Analysis of 10-steroid panel by liquid chromatography-tandem mass spectrometry (LC-MS/MS) and clinical data (mean follow-up 39 months). MAIN OUTCOME MEASURES Difference in baseline and post-DST steroid profiles between groups. Correlation with cardiovascular profile. RESULTS Patients with unilateral adenomas and ACS showed higher cortisol, 11-deoxycortisol, and corticosterone and lower dehydroepiandrosterone than those with NS adenomas. Patients with ACS hyperplasia showed higher cortisol and lower androgens in women than those with NS. Patients with ACS had reduced suppression of post-DST cortisol, 11-deoxycortisol, and corticosterone, irrespective of adrenal morphology. Post-DST cortisol and corticosterone were associated with higher prevalence of severe/resistant hypertension. Patients with ACS unilateral adenomas showed higher incidence of worsening of hypertensive disease and novel cardiovascular events than those with NS, with post-DST cortisol [hazard ratio (HR) 1.02; 95% CI, 1.01 to 1.03; P < 0.001] and baseline corticosterone (HR 1.06; 95% CI, 1.01 to 1.12; P = 0.031) among the main predictors. CONCLUSIONS Patients with adrenal incidentalomas showed different steroid profiles, depending on functional status and adrenal morphology, with implications for their cardiovascular status.

Abstract
OBJECTIVE Primary aldosteronism is associated with higher cardiovascular morbidity as compared with essential hypertension. Vascular complications encompass myocardial infarction and cerebrovascular events. Aortic damage in primary aldosteronism has never been explored, although a few cases of ascending aorta aneurisms have been reported. DESIGN AND METHODS We consecutively enrolled patients affected by primary aldosteronism (n = 45) and compared them with patients affected by essential hypertension (n = 47), on an outpatient setting. Echocardiographic data of patients with primary aldosteronism were collected during a mean follow-up of 3 years, in subjects who underwent adrenal surgery (n = 12) and those on mineralocorticoid receptor antagonists (n = 33). RESULTS AND CONCLUSION We found that patients with primary aldosteronism had larger ascending aorta diameters than those with essential hypertension before starting any specific treatment. Patients with primary aldosteronism did not show significant changes in the size of ascending aorta during a mean of 3 years of follow-up, irrespective of the type of treatment (medical vs. surgical treatment). A longer follow-up will better clarify if worsening of the aortic damage may be better prevented by surgery rather than by mineralocorticoid receptor antagonists.

Abstract
AIM To evaluate the survival of patients with unresectable perihilar cholangiocarcinoma (PHC) treated with multimodal palliative approaches. PATIENTS AND METHODS thirty-two patients were enrolled in a multimodal protocol including: bilateral biliary drainage; Yridium-192 intraluminal brachytherapy (BT); metal biliary stenting; external-beam radiotherapy (EBRT); systemic chemotherapy (ChT). All patients underwent BT and biliary stenting: this was the only treatment for 14 patients, it was combined with EBRT in 11, and with EBRT and ChT in seven. Mean and median survival, complication rates and duration of hospital stay were calculated for each group. RESULTS BT with EBRT and ChT obtained the best median (15 months) and one year (71.42%) survival followed by BT with EBRT (14 months and 63.63%, respectively). BT with EBRT in a total dose of 54-60 Gy, with or without ChT, led to a significantly higher median survival rate (14 months) than that for BT alone (seven months). CONCLUSION BT with EBRT, with or without ChT, improves survival and should be considered as a suitable alternative to palliative surgery for patients with unresectable perihilar cholangiocarcinoma.
