New Insights about Pulmonary Epithelioid Hemangioendothelioma: Review of the Literature and Two Case Reports.

Pulmonary epithelioid hemangioendothelioma (PEH) is a rare neoplasm of vascular origin. There are three different major imaging patterns identified in thoracic manifestation of epithelioid hemangioendothelioma: (1) multiple pulmonary nodules; (2) multiple pulmonary reticulonodular opacities; and (3) diffuse infiltrative pleural thickening. Radiographically, presence of bilateral multiple nodules is the most common pattern of presentation.

Isolated papillary muscle hypertrophy: A gap in our knowledge of hypertrophic cardiomyopathy?

Increased thickness of left ventricular walls is the predominant characteristic and one of the diagnostic criteria of hypertrophic cardiomyopathy (HCM). This case illustrates an uncommon but important finding of isolated hypertrophy of the papillary muscles (PMs), observed in a young woman in whom an abnormal electrocardiogram was initially detected. During the investigation isolated PM hypertrophy was identified.

Myocardial ischemia evaluation with dual-source computed tomography: comparison with magnetic resonance imaging.

Introduction And Objectives: Computed tomography does not accurately determine which coronary lesions lead to myocardial ischemia and consequently further tests are required to evaluate ischemia induction. The aim of this study was to compare diagnostic accuracy between dual-energy computed tomography and magnetic resonance imaging in the assessment of myocardial perfusion and viability in patients suspected of coronary artery disease.

Methods: A prospective study was performed in 56 consecutive patients (39 men [69.

Multiple paraganglioma in a female patient: review of genetic features.

We report the case of a female patient who presented with symptoms of catecholamine excess. Urinary catecholamines were elevated. Radiologic tests were compatible with paraganglioma.

Radiologic findings of segmental testicular infarction.

Objective: Our objective was to describe the radiologic findings of segmental testicular infarction and to establish a proper diagnosis that can avoid orchiectomy.

Conclusion: The presence of a triangular-shaped avascular intratesticular lesion on sonography or MRI and enhancement of the surrounding borders on enhanced MR images may suggest a presurgical diagnosis of segmental testicular infarction and therefore avoid a total orchiectomy in these patients.

Ovarian maldescent.

Undescended ovary is a rare disorder that can be associated with müllerian malformations. There is an unclear association with infertility and malignant disease. When an ovary is not in its normal location, it is sought in other locations above the pelvic brim.
