Spectrum of liver lesions hyperintense on hepatobiliary phase: an approach by clinical setting.
2021
AbstractHepatobiliary MRI contrast agents are increasingly being used for liver imaging. In clinical practice, most focal liver lesions do not uptake hepatobiliary contrast agents. Less commonly, hepatic lesions may show variable signal characteristics on hepatobiliary phase. This pictorial essay reviews a broad spectrum of benign and malignant focal hepatic observations that may show hyperintensity on hepatobiliary phase in various clinical settings. In non-cirrhotic patients, focal hepatic observations that show hyperintensity in the hepatobiliary phase are usually benign and typically include focal nodular hyperplasia. In patients with primary or secondary vascular disorders, focal nodul…
CT imaging findings of epiploic appendagitis: an unusual cause of abdominal pain
2019
AbstractEpiploic appendagitis is a rare cause of acute abdominal pain, determined by a benign self-limiting inflammation of the epiploic appendages. It may manifest with heterogeneous clinical presentations, mimicking other more severe entities responsible of acute abdominal pain, such as acute diverticulitis or appendicitis. Given its importance as clinical mimicker, imaging plays a crucial role to avoid inaccurate diagnosis that may lead to unnecessary hospitalization, antibiotic therapy, and surgery. CT represents the gold standard technique for the evaluation of patients with indeterminate acute abdominal pain. Imaging findings include the presence of an oval lesion with fat-attenuation…
CT and MR imaging of cystic renal lesions
2020
AbstractCystic renal lesions are a common incidental finding on routinely imaging examinations. Although a benign simple cyst is usually easy to recognize, the same is not true for complex and multifocal cystic renal lesions, whose differential diagnosis includes both neoplastic and non-neoplastic conditions. In this review, we will show a series of cases in order to provide tips to identify benign cysts and differentiate them from malignant ones.
Cerebrospinal Fluid Tau Protein Levels and <sup>18</sup>F-Fluorodeoxyglucose Positron Emission Tomography in the Differential Diagnosis o…
2010
<i>Aims:</i> In this study, we aimed to compare cerebrospinal fluid (CSF) levels of total tau (t-tau), phosphorylated tau (p-tau<sub>181</sub>) and positron emission tomography with <sup>18</sup>F-fluorodeoxyglucose (FDG-PET) in the differential diagnosis of Alzheimer’s disease (AD) under clinical conditions. <i>Method:</i> In a cross-sectional, blinded, single-center study, we examined a sample of 75 unselected memory clinic patients with clinical diagnoses of dementia of Alzheimer type (DAT; n = 24), amnestic mild cognitive impairment (MCI; n = 16), other dementias (n = 13) and nondemented controls (n = 22). Discriminative accuracy, sensitiv…
Diagnostic challenges and potential early indicators of breast periprosthetic anaplastic large cell lymphoma
2020
Abstract Rationale: Anaplastic large T-cell lymphoma (BI-ALCL) is a rare primitive lymphoma described in women with breast implant prostheses, which has been arousing interest in recent years due to its potentially high social impact. The difficult diagnosis associated with the high and increasing number of prosthetic implants worldwide has led to hypothesize an underestimation of the real impact of the disease among prosthesis-bearing women. The aim of this work is to search for specific radiological signs of disease linked to the chronic inflammatory pathogenetic mechanism. Patient concerns: This work describes a case of BI-ALCL in an American woman with no personal or family history of c…
Abdominal Tumor in a 14-Year-Old Adolescent: Imperforate Hymen, Resulting in Hematocolpos—A Case Report and Review of the Literature
2014
Background. Abdominal masses in female adolescents are uncommon. A rare cause of this condition is hematocolpos due to imperforate hymen.Case. We present a case of an unusually massive asymptomatic abdominal bulk in a 14-year-old female patient, who sought for medical advice after unusual abdominal pain lasting for few weeks. The patient was otherwise asymptomatic, apart from an unusual dramatic expansion of her abdominal wall during the last month. We describe the surgical management and the follow-up of the patient.Summary and Conclusion. Clinicians should keep in mind that an imperforate hymen can cause abdominal growth due to hematocolpos and include it in the differential diagnosis of …
Necrobiotic xanthogranuloma. Differential diagnosis, treatment and systemic involvement. Case report
2014
Abstract Case report A 48-year-old male was referred to our hospital for further evaluation of eyelid edema with bilateral yellowish ulcerated nodules. Suspecting a xanthogranulomatosis, imaging tests and biopsy were performed with diagnosis of necrobiotic xanthogranuloma. IgG monoclonal gammapathy was diagnosed in a systemic study. Systemic corticosteroids and cyclosporine were initiated unsuccessfully; therefore, intra-lesional injections of triamcinolone were started, which controlled the orbital disease. Discussion Necrobiotic xanthogranuloma is a rare condition that usually affects the eyelids and anterior orbit. Its diagnosis is important as it is associated with malignant lymphoproli…
Management of Pulmonary Embolism: Results from the German Chest Pain Unit Registry.
2020
<b><i>Introduction:</i></b> Since 2008, specialized chest pain units (CPUs) were implemented across Germany ensuring structured diagnostics in acute chest pain. This study aims to analyze the management of pulmonary embolism (PE) patients in such certified CPUs. <b><i>Methods:</i></b> Data were retrieved from 13,902 patients enrolled in the German CPU registry and analyzed for the diagnosis of PE including patient characteristics, critical time intervals, diagnostic workup, treatment, and prognosis. PE patients were compared to the overall CPU patient cohort. Only patients with a complete 3-month follow-up were included. <b><i>Resu…
Kutane Manifestationen der essentiellen Thrombozyth�mie Erythromelalgie, isch�mische Akrozyanose, Livedo racemosa*
1995
A case report is presented to illustrate the cutaneous manifestations in essential thrombocythaemia. Knowledge of the related skin lesions may lead to earlier detection of this myeloproliferative disorder. Treatment may prevent severe haemorrhagic or thrombotic complications. Erythromelalgia is causally related to thrombocythaemia; prompt relief of painful symptoms after treatment with aspirin is typical.
Dental considerations in patients with respiratory problems.
2011
Many respiratory disorders can compromise routine dental care and require special treatment for the affected patients. Patients often visit the dental clinic with respiratory problems already diagnosed by other specialists. The dental professional therefore must provide correct dental care in the context of such a diagnosis. The present study offers a literature review of those respiratory disorders which can have implications for dental care. Chronic obstructive pulmonary disease (COPD) and asthma require special measures, such as working with the patient in the vertical position, since some of these subjects do not tolerate decubitus. On the other hand, patients with COPD can suffer infec…
