Multimodality Imaging Appearance of Intrapericardial Paragangliomas.

ABSTRACT: Paragangliomas are neuroendocrine tumors of the sympathetic and parasympathetic nervous system that originate from neural crest cells. Less than 1% of paragangliomas are found in the heart, originating from intrinsic cardiac ganglia cells in the posterior wall the atria, atrioventricular groove, and along the root of the great vessels. A 10-year review of our institution's database identified nine patients who had documented intrapericardial paragangliomas. We describe the multimodality imaging appearance of these tumors. The most common findings include embedment and wrapping around the great vessels and atrioventricular groove within the confines of the pericardium, markedly avid heterogeneous enhancement, distinct engorged neovascularization, and in large lesions, central low attenuation areas compatible with hemorrhage, necrosis, or cystic degeneration.

A case report of malignant primary pericardial mesothelioma with atypical imaging appearance: multimodality imaging with histopathological correlation.

Project description:BackgroundPrimary pericardial mesothelioma is a rare primary cardiac malignancy, with three main histopathological types, sarcomatoid histotype being the rarest. The imaging features were atypical due to concomitant extensive calcification, which resulted in aggravated differential diagnosis.Case summaryA 45-year-old man presented to our hospital with non-specific clinical symptoms. According to clinical history, a mediastinal tumour had been suspected with a previous unsuccessful attempt of transthoracic computed tomography-guided biopsy at an overseas hospital with limited data of performed imaging procedures. Multimodality imaging at our centre revealed extensively calcified solid masses in the pericardium, invading the left atrium. As the imaging features suggested an atypical primary pericardial malignancy, a diagnostic thoracoscopy was performed. Histopathological analysis of specimen revealed sarcomatoid type of pericardial mesothelioma with areas of necrosis and foci of osteogenic differentiation. Despite planned treatment, 2 weeks after histological diagnosis, the patient passed away due to perforated peptic ulcer-related sepsis.DiscussionThe presence of extensive calcification in the lesion resulted in a challenging imaging workup and diagnosis. Initial differential diagnosis included primary or metastatic calcification-prone tumour, secondary calcification due to haemorrhage after previous interventional procedure and other pathologies, such as tuberculous pericarditis, calcified amorphous tumour, among others. Calcification may be part of the histological tumour characteristics; however, proper history taking is crucial as concomitant diseases, previous treatment, and interventional procedures may alter the imaging pattern.

Multimodality Imaging in Cardiooncology.

Project description:Cardiotoxicity represents a rising problem influencing prognosis and quality of life of chemotherapy-treated patients. Anthracyclines and trastuzumab are the drugs most commonly associated with development of a cardiotoxic effect. Heart failure, myocardial ischemia, hypertension, myocarditis, and thrombosis are typical manifestation of cardiotoxicity by chemotherapeutic agents. Diagnosis and monitoring of cardiac side-effects of cancer treatment is of paramount importance. Echocardiography and nuclear medicine methods are widely used in clinical practice and left ventricular ejection fraction is the most important parameter to asses myocardial damage secondary to chemotherapy. However, left ventricular ejection decrease is a delayed phenomenon, occurring after a long stage of silent myocardial damage that classic imaging methods are not able to detect. New imaging techniques including three-dimensional echocardiography, speckle tracking echocardiography, and cardiac magnetic resonance have demonstrated high sensitivity in detecting the earliest alteration of left ventricular function associated with future development of chemotherapy-induced cardiomyopathy. Early diagnosis of cardiac involvement in cancer patients can allow for timely and adequate treatment management and the introduction of cardioprotective strategies.

Multimodality Imaging in Carotid Web.

Project description:Purpose: Carotid web (CaW) is an underrecognized cause of cryptogenic stroke in young patients. The optimal imaging for CaW is unknown. We aim to evaluate the diagnostic accuracy of diverse imaging modalities for the diagnosis of CaW. Methods: Retrospective analysis of institutional neurovascular database was performed to identify patients with multimodal (CT angiogram-CTA, digital subtraction angiogram-DSA, and/or ultrasound-US) imaging diagnosis of CaW or atherosclerosis. Baseline clinical demographics were recorded. Blinded image analysis was performed for each imaging modality by separate readers. Discrepancies were settled by consensus. Two-sided Cohen's Kappa (κ) coefficient was used to evaluate the inter-rater agreement for the etiological diagnosis between imaging modalities. Results: Thirty patients/60 carotids were evaluated by CTA and 55 carotids were included. Patients with symptomatic CaW (n = 20), compared to individuals with atherosclerosis (n = 10), were younger (49 ± 9 vs. 60 ± 8 years; p < 0.01), more commonly female (75% vs. 30%; p = 0.01), and less frequently presented vascular risk factors: Hypertension (40% vs. 100%; p < 0.01), hyperlipidemia (0% vs. 50%; p < 0.01), diabetes (10% vs. 40%; p = 0.05), and smoking (5% vs. 70%; p < 0.01). High inter-rater correlation strength existed for CTA (n = 55; κ = 0.88; p < 0.0001) and DSA (n = 28; κ = 0.86, p < 0.0001) readers for lesion diagnosis while US inter-rater agreement was lower (κ = 0.553; p = 0.001). Across modalities CTA and DSA shared very high strength of agreement (κ = 0.92; p < 0.0001), compared to a less pronounced agreement between US and CTA (κ = 0.553; p = 0.001). The strength of correlation between DSA-CTA was significantly more robust as compared to US-CTA (Z = 3.58; p = 0.0003). Conclusion: CTA and DSA demonstrated comparable and superior performance as compared to US in the diagnosis of CaW.

Multimodality imaging of Abernethy malformation.

Project description:Abernethy malformation, or congenital extrahepatic portosystemic venous shunt, is a rare anomaly involving the portal venous system. Despite its rarity, it is increasingly being reported, and therefore, it is important to diagnose given the potential adverse clinical consequences if left untreated. It has a spectrum of presentations, ranging from complete lack of symptoms, to causing hepatic carcinoma, hepatic encephalopathy, severe pulmonary hypertension, and diffuse pulmonary arteriovenous malformation. We herein describe the case and echocardiographic, computed tomography, and magnetic resonance imaging findings of a transgender individual, with this anomaly detected incidentally during adulthood.

Multimodality Imaging of Prostate Cancer.

Project description:Prostate cancer is a very heterogeneous disease, and contemporary management is focused on identification and treatment of the prognostically adverse high-risk tumors while minimizing overtreatment of indolent, low-risk tumors. In recent years, imaging has gained increasing importance in the detection, staging, posttreatment assessment, and detection of recurrence of prostate cancer. Several imaging modalities including conventional and functional methods are used in different clinical scenarios with their very own advantages and limitations. This continuing medical education article provides an overview of available imaging modalities currently in use for prostate cancer followed by a more specific section on the value of these different imaging modalities in distinct clinical scenarios, ranging from initial diagnosis to advanced, metastatic castration-resistant prostate cancer. In addition to established imaging indications, we will highlight some potential future applications of contemporary imaging modalities in prostate cancer.

Multimodality Imaging Findings in Cardiac Plasmacytoma.

Project description:Extramedullary plasmacytoma involving the heart is a rare occurrence. We present the case of a 74-year-old man who received a diagnosis of cardiac plasmacytoma in the context of relapsed multiple myeloma. The tumor primarily presented as a solitary extramedullary plasmacytoma with extensive infiltration into the right ventricle, leading to mild symptoms such as dyspnea. There was no evidence of systemic involvement. A treatment with DRd (daratumumab, lenalidomide, and dexamethasone) was promptly initiated. This case demonstrates the effective use of multimodal imaging techniques to characterize cardiac masses and to determine the most appropriate management plan.

Multimodality imaging of anomalous pulmonary veins.

Project description:Partial anomalous pulmonary venous connection (PAPVC) is an extremely rare congenital condition where one or more of the pulmonary veins are connected to the venous circulation. Although initially suspected with unexplained right ventricular enlargement on transthoracic echocardiography (TTE), cardiac MRI is able to delineate the anatomical variant. We present a case of a 65-year-old male diagnosed with left sided PAPVC using multimodality cardiac imaging.

Imaging features of retroperitoneal extra-adrenal paragangliomas in 10 dogs.

Project description:Retroperitoneal paragangliomas are rare tumors of the neuroendocrine system. Only a few canine case reports are available with rare descriptions of their imaging features. The objectives of this multi-center, retrospective case series study were to describe the diagnostic imaging features of confirmed retroperitoneal paragangliomas and specify their location. Medical records and imaging studies of 10 affected dogs with cytological or histopathologic results concordant with retroperitoneal paragangliomas were evaluated. Dogs had a median age of 9 years. Four of them had clinical signs and laboratory reports compatible with excessive production of catecholamines. Six ultrasound, four CT, four radiographic, and one MRI studies were included. The paragangliomas did not have a specific location along the aorta. They were of various sizes (median 33 mm, range: 9-85 mm of length). Masses had heterogeneous parenchyma in six of 10 dogs, regardless of the imaging modality. Strong contrast enhancement was found in all CT studies. Encircling of at least one vessel was detected in six of 10 masses, clear invasion of a vessel was identified in one of 10 masses. In five of 10 cases, the masses were initially misconstrued as lymph nodes by the on-site radiologist. Retroperitoneal paragangliomas appear along the abdominal aorta, often presenting heterogeneous parenchyma, possibly affecting the local vasculature, and displaying strong contrast enhancement on CT. Clinical signs can be secondary to mass effects or excessive catecholamine production. Underdiagnosis and misdiagnosis of this tumor are suspected as they can be silent, of small size, or confused with other structures.
